50% fewer moving parts than standard piston-type compressors. This equates to much improved reliability and improved efficiency. Scroll compressors are also much quieter inoperation than their piston-type counterparts. And, while all heat pumps are known for their low operating noise levels.

The cabinet of the ZA1 model , being made from resilient, UV-Protected ABS material, has superior fade resistance and can never rust or corrode. You can expect the cabinet to retain a like-new appearance with only an occasional wash down and if so desired a quick waxing.

Hot Gas Defrost*

Hot gas defrost heat pumps are uniquely equipped for an active defrost cycle. Active def-rost involves directing hot refrigerant vapor to the heat collector, melting accumulated iceaway in a matter of a few minutes... then right back to heating. Standard defrost heat pu-mps may remain off in defrost for extended periods during very cold weather. Becau-se of their ability to continue to operate-even during freezing weather-hot gas defrost models extend the swimming season longer than any standard-defrost heat pump.

PLEASE READ FURTHER TO BECOME FAMILIAR WITH ALL THE FEATURES, THE SAFEOPERATION, AND THE CARE OF YOUR NEW HEAT PUMP.


The heart of your heat pump is the patented heat exchanger. One of the primary causes of premature heat pump demise is the failure of the heat exchanger. Ordinary heat exchangers are made from a cupronickel alloy . This cupron-ickel material is susceptible to attack from the sanitizers used in pools and spas and from other related water chemistry conditions. Once the heat exchanger fails, the heat pump isruined.

The heat exchanger tube is made from titanium, and is virtually impervious to water chemistry damage,

and the shell is made by PVC

And The PVC is can't bear too high pressure and temperature, and exit the risk of

burst and leak. and the shell is made a patent secret ingredients,

it can stand more than 21kg water pressure and high temperature.

1. Positioning Your Swimming Pool Heat Pump1.1 For correct operation air must be free to circulate around the heat pump. Do not place the unit in a shed, greenhouse or similar. This unit is designed to be placed outdoors only.1.2 Refer to the drawing below for required clearance.1.3 You should position the heat pump so that the control panel does not face directly towards the sun.1.4 The heat pump must be upright.1.5 The distance between the heat pump and the pool / plant room should be as short as practically possible to reduce pressure and heat loss in the pipe work.1.6 Insulating the pipe work will assist with the prevention of heat losses.1.7 An isolator switch should be installed (by a qualified electrician) near the heat pump.1.8 The electrical supply to the heat pump must be protected by a 30mA RCD.1.9 The air inlets and outlets must not be obstructed or blocked.1.10 Even though the heat pump is low noise, it must be positioned so as to be considerate to neighbours.1.11 Your heat pump must be placed on a solid base.1.12 Condensation will drip from underneath the heat pump, your base must be able to tolerate this.

2. Connecting Your Swimming Pool Pipe Work2.1 The pool water is fed through the heat pump by a swimming pool pump.2.2 The heat pump must be installed after (down stream) the swimming pool filter so clean, filtered water passes through it.2.3 Double union ball valves must be fitted just before the heat pump inlet and just after the outlet to aid servicing and winterising.2.4 Each heat pump has a maximum water flow rate. If the flow via the pool pump is higher than this then a by-pass should be installed. Consult your supplying dealer.2.5 Each heat pump also has a minimum flow rate, below this the heat pump will not operate. Consult your supplying dealer.2.6 Pipe work of less than 1-1/2 diameter should not be used.2.7 Fit a union nut onto each pipe.2.8 Push the gasket over the pipe until the gasket is about 5 -10mm from the edge of the pipe. You may need to lubricate the gasket.2.9 Insert the pipe into the heat pump and tighten the union nut.2.10 The union must only be hand tightened.2.11 If the swimming pool is equipped with a chlorinator, brominator, or possibly chemical control with acid and chlorine pumps, these must be in the return pipe work after the heat pump and a non-return valve used. Any dosing system must be the final equipment before the water returns to the swimming pool. Damage caused to the heat pump by chemical dosing units is not covered by warranty.2.12 Any heat exchanger or electric heater fitted as auxiliary heating must be installed after (down stream from) the heat pump so as to avoid pre-heating the pool water before it enters the heat pump.

If you are having a problem with your pool heater, FIRST perform the consumer troubleshooting steps

detailed in your pool heater Owners Manual then CALL THE INSTALLING DEALER and have him verify

that the cause is NOT external to your pool heater (such as tripped breaker, clogged pool filter, inadequate

pump run time ,etc.)

1. Provide your Dealer with the following information:

A. Serial # located on back panel nameplate of your pool heater.

B. Proof of Installation Date(Bill of sale or original invoice only)

C. Description of the Symptoms

Will Never Need Freon

Unless your pool heater has a leak in the sealed refrigeration system, the factory charge of freon should last

for the life of the unit. Freon is very stable and should not degrade or breakdown even under severe operating

conditions. If your unit needs freon, then it has a leak, and adding freon will not solve the problem. The leak

must be located and repaired. Fortunately, freon leaks are very uncommon and usually are due to shipping.

For Installing Dealer

If your customer is having a problem with your pool heater and you as the installing dealer have

verified that the cause is NOT external to your pool heater(such as tripped breaker, clogged pool filter,

inadequate pump run time, etc.)following these steps will help you obtain the fastest service possible

for your customer.

1. Help your customer gather the following information:

A. Serial # located on back panel nameplate of your pool heater.

B. Proof of Installation Date(Bill of sale or original invoice only)
