To prevent such risks, install and operate ROTEX Sanicube only:– as stipulated and in perfect condition,– with an awareness of the safety and hazards involved.This assumes knowledge and use of the contents of this manual, the relevant accident prevention regulations and the recognised safety-related and occupational medical rules.

1.4 Proper use

The ROTEX Sanicube may only be used as a hot water storage tank. The ROTEX Sanicube must be installed, connected and operated only according to the information in this manual.

Only those electric immersion heaters supplied by ROTEX may be used.

Any other use outside the above-mentioned use is considered as improper. Any resulting damages will be borne by the user/owner alone.

Intended use also includes compliance with the maintenance and service conditions. Spare parts must at least satisfy the technical requirements defined by the manufacturer. This is the case, for example, with original spare parts.

1.5 Instructions for operating safety

Before working on the hot water storage tank and the heating system• Work on the hot water storage tank and heating system (e.g. installation, connection and initial start-up) should only be

carried out by authorised and trained heating experts.• Switch off the mains supply before starting any work on the hot water storage tank and heating system and secure it against

unintentional switch-on.• Seals must not be damaged or removed.• Make sure that the safety valves comply with the requirements of EN 12828 when connecting on the heating side, and with

the requirements of EN 12897 when connecting on the domestic water side.

Electrical installation of optional accessories• Electrical installations may only be carried out by qualified electrical technicians under observance of the relevant electrical

guidelines and the regulations of the electric utilities company.• Compare the mains voltage indicated on the nameplate with the supply voltage before connecting to the mains.

Installation room• Only erect the ROTEX Sanicube if a ground load-bearing capacity of 1050 kg/m² plus safety factor is guaranteed. The ground

must be flat and level.• Erection outdoors is only possible to a limited extent. The storage tank must not be continuously exposed to direct sunlight.• The ROTEX Sanicube must be protected from frost.

Corrosion protectionIn a few regions, the water utility company supplies corrosive domestic water, which can result in corrosion damage even if high-quality stainless steel is used. Ask your water utility whether the use of hot water storage tanks made from stainless steel results in problems with corrosion in your area.

Suitable water treatment may be needed.

2.2 Brief description

The ROTEX Sanicube is a combination of heat storage tank and instantaneous water heater.

The pressureless storage water serves as heat storage medium. Useful heat is supplied and removed via the spiral corrosion-resistant heat exchanger, which is made from a corrugated stainless steel pipe (1.4404), and is completely immersed in the storage tank water. In the heat exchanger for domestic hot water there are approx. 24 litres (19 l on SCS 328/14/0) of domestic water stored at the temperature level of the readiness zone.

The cold water which flows out when the hot water is removed is first routed to the storage tank at the very bottom of the heat exchanger, where it cools the lower area of the storage tank down as much as possible. The readiness zone is heated by an external heat generator (condensing boiler, Solaris, electric immersion heater). Water flows through the heat exchanger for storage charging (SL-WT) from top to bottom.

On its way to the top, the domestic water continuously absorbs the heat of the storage tank water. Since the flow direction makes use of the counter flow principle, and the heat exchanger is shaped like a spiral, there is definite temperature stratification within the storage tank. As high temperatures can be maintained for a very long time in the upper section of the storage tank, a high hot water output is achieved even if water is drawn off over a long period of time.

The hot water storage tank in the ROTEX Sanicube INOX Solaris can also be heated by solar energy. In the ROTEX Sanicube Solaris, the solar zone in the lower part of the tank is cooled by the cold water flowing in. Cooling also takes place on the heating side if the heating return temperature is lower than the temperature of the storage tank water. This means that the solar energy installation always operates at maximum efficiency and produces the maximum heat yield.

2.3 Advantages

Optimum water hygieneLow flow or unheated zones on the domestic water side are completely excluded with the ROTEX Sanicube. It is impossible for sludge, rust or other sediments to be deposited, as can be the case with other large volume tanks. The water which is fed into the system first is also discharged first (first in, first out principle).

Low maintenance and corrosionThe ROTEX Sanicube is made of plastic and is completely corrosion free. Sacrificial anodes or similar anti-corrosion units are not necessary. This means that associated maintenance work, e.g. changing the protective anodes or cleaning the storage tank, does not need to be carried out on the ROTEX Sanicube. Only the fill level of the storage tank water needs to be checked.

The corrugated stainless steel pipe heat exchangers on the heating and domestic water side are made from high quality stainless steel (1.4404).

Low scalingOn the storage tank side only one deposition of scale is possible. The immersion heater therefore remains clean, as do the stainless steel heat exchanger pipes in the storage tank water. This means that no scale can build up which would continuously reduce the efficiency of heat transfer in the course of operation (as is the case with other storage tank designs).

The thermal and pressure expansion and high flow rates in the domestic water heat exchanger release any possible scale deposits, which are then flushed away.

Economical operationThe full area heat insulation of the storage tank ensures very low heat losses in use and means that the best use is made of the heat energy being applied.

Modular extension facilityIf the heat output of a single ROTEX Sanicube is not adequate you can interconnect several storage tanks.

Electronic controlA control system integrated in the heat generator controls all heating and hot water functions for the direct heating circuit, a mixed heating circuit which can be connected as an option and a storage tank charging circuit.

SCS only : Settings, displays and functions of the Solaris heating are e.g. carried out by the regulating and pump station RPS3.



2.4 Accessories

2.4.1 Electric immersion heaters

In addition to the heating possibilities via the corrugated stainless steel pipe heat exchanger from various different heat sources and energy carriers, the ROTEX Sanicube can also be charged using an electric immersion heater.

2.4.2 Non return valves

In order to prevent heat losses from the connection pipes when the heating pump is switched off and during periods without domestic water being drawn off (gravity circulation) you should fit non return valves (set – 2 pcs, 16 50 70) in the connections to the ROTEX Sanicube.

2.4.3 Dirt filter

If the ROTEX Sanicube is connected to a heating system with steel pipes, radiators or non-diffusion-proof floor heating pipes, slurry and swarf could enter the hot water storage tank and cause blockages, local overheating or corrosion. This can be prevented by fitting a dirt filter.

– for units up to 28 kW: SFR 28 ( 15 60 11)– for units up to 50 kW: SFR 50 ( 15 60 12)

2.4.4 Scalding protection

There is a danger of scalding at hot water temperatures over 60 °C. The fitting of scalding protection means that the hot water temperature can be varied continuously and limited from 35–60 °C.

– Scalding protection VTA 32 ( 15 60 15)– Screw fittings set 1" ( 15 60 16)

2.4.5 Thermometer Set

The thermometer THSS ( 16 50 20) can be fitted for analogue display of the storage tank temperature.

3.2 Set-up

CAUTION:

• Only erect the ROTEX Sanicube if a ground load-bearing capacity of 1050 kg/m² plus safety factor is guaranteed. The ground must be flat and level.

• Erection outdoors is only possible to a limited extent. The storage tank must not be exposed to continuous direct sunlight, as the UV radiation and the effects of the weather will damage the plastic.

• The ROTEX Sanicube must be protected from frost.• Make sure that the supply company does not provide corrosive domestic water.

– Suitable water treatment may be needed.

Incorrect set-up and installation would render the manufacturer's guarantee void.

If you have questions, please contact our Technical Customer Service.

• Remove the packaging and dispose of it in an environmentally sound manner.

• Transport the ROTEX Sanicube carefully, using the handles provided.

• Install the ROTEX Sanicube at the installation site. Recommended wall distance of 200 mm must be observed.

• When using an electric immersion heater (see Chapter 2.4.1 "Electric immersion heaters"), it must be screwed into the cover opening in the ROTEX Sanicube (see Fig. 3-5 and Fig. 3-6, Item 18).– With restricted headroom tilt the ROTEX Sanicube until the

electric immersion heater can be fitted without damage.

Fig. 3-5 Mounting position of electric immersion heater

Only connect the immersion heater to the mains supply on the distribution board of the domestic installation after the ROTEX Sanicube has been filled up (see Chapter 3.3.8 "Connecting the electric immersion heater (accessories)").

3.3 Installation

3.3.1 Overview of connections

Instructions for water connection

• For domestic water pipes observe the stipulations of EN 806 and EN 1717.• The position and dimensions of the connections can be found in Fig. 3-6 / Fig. 2-1.• Carefully lag the hot water pipes to prevent heat loss.• Install the hot water storage tank near to the removal point to dispense with the need for a circulation pipe. If a circulation

pipe is essential then it must be installed in accordance with the schematic drawing in Fig. 3-1, Fig. 3-2, Fig. 3-3 or Fig. 3-4.

– Avoiding deposits: Observe the regulations in VDI 2035 in order to avoid corrosive products and deposits. If the filling and additional water has a high degree of hardness, measures must be taken to stabilise this hardness or soften the water.

CAUTION!

If the ROTEX Sanicube is connected to a heating system with steel pipes, radiators or non-diffusion-proof floor heating pipes, slurry and swarf could enter the hot water storage tank and cause blockages, local overheating or corrosion.

• Flush the feed pipes before filling the heat exchanger.• Rinse out the heat distribution network (in the existing heating system).• Fit dirt filter in the heating return pipe (see Chapter 2.4.3 "Dirt filter").

WARNING!

There is a danger of scalding at water temperatures >60 °C. This can arise with solar energy utilisation, if the Legionella protection is activated or if the target temperature is set to >60 °C.

• Fit scalding protection (see Chapter 2.4.4 "Scalding protection").

3.3.2 Hydraulic connection

1. When using non return valves (see Chapter 2.4.2 "Non return valves"), these should be fitted in the pipe connections on the ROTEX Sanicube.

2. Connect the drain hose to the safety overflow connection (Fig. 3-6 / Fig. 2-1, connection 27).

– Use transparent drain hose (draining water must be visible).– Connect the drain hose to an adequately dimensioned waste water installation.– Drain should not be lockable.

3. Check the water pressure at the cold water connection (<6 bar).

If the pressure in the domestic water supply is greater then fit a pressure reducer and limit the water pressure to <6 bar.

4. Establish a connection to the cold water supply (Fig. 3-6, connection 2).

5. Establish connections to the hot water distribution network.

6. Establish connections to the heating circuit.

– When connecting the heating side of the ROTEX Sanicube you must always ensure proper de-areation of the storage tank charging pipes (e.g. by the use of automatic vent valves at connections 4 to 9, Fig. 3-6 / Fig. 2-1).

7. Establish connections to the heat generator.

8. Establish connections to the Solaris System (optional).

– See Solaris installation and maintenance instructions.

3.3.3 Interconnection of several storage tanks

If the heat output of a single ROTEX Sanicube is not adequate you can interconnect several ROTEX Sanicube modules.

This means that both the stainless steel heat exchangers for post-heating and the hot water heat exchangers are interconnected in accordance with the Tichelmann principle (SC: Fig. 3-3, SCS: Fig. 3-4).

With seasonal variations in demand these individual units can be added or taken out of service accordingly. In this way the total hot water output can be manually matched to the actual demand.

In Chapter 6.2 "Performance diagrams" you can see what efficiency characteristics can be achieved by interconnecting several ROTEX Sanicube units.

For Solaris only:

1 ROTEX Sanicube Solaris2 Regulation and pump unit RPS 3 3 Solaris – flow manifold4 Connecting T piece

AGL Equalisation pipeCON SX A Storage tank extension set (bottom)CON SX B Storage tank extension set (top)FLG FlowGuardFLS FlowSensor

For the interconnection of several ROTEX Sanicube Solaris units you can purchase the Solaris Storage Tank Extension Set CON SX, the equalisation pipe AGL, and the Solaris FlowGuards and the Solaris FlowSensor. For purchasing information see Chapter 2.4.6 "Solaris storage tank extension set".

The fitting and operation of these accessories is described in detail in the Solaris operating and installation instructions.

Fig. 3-7 Schematic drawing of the Solaris storage tank extension equipment



3.3.4 Filling the hot water heat exchanger

1. Open the shutoff valve for the cold water supply pipe.

2. Open the hot water tap connections so that the draw-off volume can be set as high as possible.

3. Once water has been discharged from the tap connections, do not interrupt the cold water inflow; this will ensure that the heat exchanger will be fully vented and that any impurities or residue will be discharged.

3.3.5 Filling the storage tank (without Solaris System installed)

1. Connect the filler hose with back flow preventer (½") via the hose connector provided to the filling and drain connection (Fig. 3-6, Item 11).

2. Fill the storage tank (Fig. 3-6, Item 10) until water comes out of the safety overflow connection (Fig. 3-6, Item 27).

3.3.6 Filling the storage tank (with Solaris System installed)

1. Connect the filling hose with return flow inhibitor (½") to the KFE cock on the control and pump unit (RPS).

2. Fill the storage tank (Fig. 3-6, Item 10) until water comes out of the safety overflow connection (Fig. 3-6, Item 27).

3.3.7 Filling the heating system and the storage tank charging circuit

• Fill and bleed the heating system and storage tank charging circuit in accordance with the installation and operating instructions for the particular heat generator.

3.3.8 Connecting the electric immersion heater (accessories)

5 x Operation and Maintenance

5 Operation and Maintenance5.1 Operation

5.1.1 Storage tank

No separate controller is required to operate the ROTEX Sanicube. The regulation is effected in each case by the control system of the connected heat generator and, in the case of Solaris installations, by the Regulation and Pump Station.

• Check the level in the storage tank (see Chapter 2 "Product description", Fig. 2-1) at regular intervals and top up with water if required.

5.1.2 Electric immersion heater (accessory)

CAUTION!

If the electric immersion heater is used when the storage tank is not completely full this can lead to a reduction in heating efficiency and can cause an electrical fault under certain circumstances.

• Only use the electric immersion heater when the storage tank is completely full.

• Set the target temperature using the regulating knob on the electric immersion heater.– The ranges between positions B, C and D are

continuously adjustable.

5 x Operation and Maintenance

5.2 Service and maintenance

The ROTEX Sanicube is practically maintenance free as a result of its design. No corrosion protection equipment is required (such as sacrificial anodes). This means that associated maintenance work, e.g. changing the protective anodes or cleaning the inside of the storage tank, does not need to be carried out.

Regular inspection of the ROTEX Sanicube guarantees a long working life and fault-free operation.

Tests performed during the annual service:

– Visual check of general condition of the ROTEX Sanicube.– Visual check of connections and pipes. In the event of damage determine the cause

Replace defective parts.

– Check all electrical components, connections, and cables.

Repair damaged parts or replace them.

– Check the water pressure of the cold water supply (<6 bar)

and if necessary the fitting or adjustment of the pressure reducer.

– Visual check of the water storage tank level (water level at the overflow point).

If necessary, top up the supply water to the overflow point.

– Check the connection of the safety overflow and drain hose for leaks, free drainage and gradient.

If necessary clean the safety overflow and drain hose and and re-route, replace damaged parts.

Clean the storage tank (annually)• The low-maintenance plastic must only be cleaned with a soft cloth and a mild detergent.• Do not use cleaning agents containing aggressive solvents, as this will damage the plastic surface.

WARNING!

Live parts can cause an electric shock on contact and cause fatal burns and injuries.

• If there is an electric immersion heater or regulation and pump station installed in the ROTEX Sanicube then these components must be isolated from the power supply before starting the inspection and maintenance work (e.g. fuse, main switch switched off and secured against inadvertent switching on again).

WARNING!

All work performed on live components must be carried out in accordance with the proper procedures, otherwise there may be a danger to the life and health of individuals and the function may be impaired.

• Rectification of damage to live components must only be carried out by heating engineers authorised and recognised by the energy supply company.
