1. SYSTEM DESCRIPTION

1.%2% Scope of works

In this project, our scope of works including supply and install of :-

A. Fan Coil Unit

1.2. System Description

The Proposed Development is located at.

a) Fan Coil Units

Fan coil units are installed in all area located on LG floor, UG floor and Ground floor

which required individual air-conditioning control. Fresh air for those rooms has been

provided by pre-treated air supplied by pre-treated air handling units. Electrical duct

heaters are provided for some rooms and common area.

2. OPERATION AND MAINTENANCE INSTRUCTIONS

2.1. Manual Operation

a) Fan Coil Unit

Start

1. Ensure fuse spur for FCU is normal

2. Switch on fan at wall mounted thermostat

3. FCU starts

Stop

1. Switch “off” fan at wall mounted thermostat

2. FCU Stops

2.2 MAINTENANCE SCHEDULE (MVAC)

2.2.1 Monthly Works

(a) General

(i) To check the general condition of the plant and equipment. To

ensure that the plant and equipment are satisfactorily operating

within design conditions;

(ii) To check the lubricating system of all running parts; cleaning,

greasing and oiling where necessary;

(iii) To check any water leakage from the pipe work and to repair if

required;

(iv) Visual checking on all supply and return grilles and louvers,

cleaning if necessary;

(v) To check the corrosion of metal surface, framework and

support/mounting brackets, etc., and to reinstate the surface by

removing rust and repaint if necessary;

(vi) To check the operation conditions of the water treatment system.

(vii) To check & record the reading of the pressure & temperature gauge

at suction and discharge water pipe which are on normal operating

condition.

(b) Fan Coil Units

(i) To check that the fan coil units and its control/sensing devices are

functioning properly and inspect drain pipes to ensure no clogging

and flooding. Rectify if necessary;

(ii) To check and clean the condensing water drain pan, drain pipes to

ensure no clogging and flooding. Rectify if necessary; and

(iii) Visual checking on surface condition of the supply and return air

grilles and filter, cleaning as necessary.

(iv) To check the operation and overheat cut-out of duct heater if

available

1.2.2 Half Yearly Works

Half-yearly service and maintenance shall include the following items:-

(a) To inspect the condition of pipe fittings, supports, ductworks,

hangers, etc., for sign of corrosion. Remove the rust and repaint

with primer and finish coating as necessary;

(b) To check the performance of controls and safety cut-outs and

check all control panel indication lamps, rectify as required;

(c) To clean electrical panels including wiring terminals and

connection points as required;

(d) To touch up with finish-coating where there is any rust or sign of

corrosion of the equipment by first removing the rust/corrosion;

(e) To check and adjust, if necessary, the air flow in the air-ductwork

system;

(f) Visual checking on air-cooled chiller’s condenser coils, cleaning

by high-pressure water or steam jet with approved cleaning

detergent if necessary;

(g) Visual checking on cooling/heating coils of all AHUs/

PAUs(excluding fan coil units), cleaning by high-pressure water

or steam jet with approved cleaning detergent if necessary;

(h) To check and serve all IAQ control and sensing equipment

including CO2 sensors, air movement sensors, thermostat,

pressure sensors, temperature sensors and volume control

dampers as necessary; and

(i) To inspect all components of ventilation system for cleanliness

and microbial growth and clean them as necessary at no cost to

Government.

1.2.3 Annual Works

(a) To inspect the condition of pipe fittings, supports, ductwork, hangers,

etc., for sign of corrosion. Remove the rust and repaint with primer

and finish coating as necessary;

(b) To check the condition of pipe work and ductwork. Recondition and if

instructed, replace the deteriorated portion in accordance with

acceptable engineering practice and standard;

(c) To refit the isolating valves, change the valve gland and gasket, and

recondition the globe valves, etc. if necessary;

(d) To examine, check and maintain the proper operation of associated

electrical panels in the plant room. Repair and renew as appropriate;

(e) To check, test and recalibrate or replace as necessary, all control and

safety devices;

(f) To check, test, adjust, clean and repair/rectify defects if required for all

electronic circuit boards and control/ sensing/ detection devices

including building automation system if available in the system;

(g) To inspect and clean all internal surface of ductwork including the

supply and return air plenums if necessary. The cleaning of the

ductwork shall not affect the normal operation of the building. The

contractor shall arrange the cleaning after the office hours of the

building;

(h) To inspect aluminum foil, paints or other concrete sealing layers and

wall surface which meant to stop radon gas emission and provide all

necessary touch up work; and

(i) Check operation of all fire damper, fire & smoke damper and issue the

ventilation certificate
