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
