INSTALLATION, START-UP AND SERVICE
INSTRUCTIONS FOR FCA18 INDOOR UNIT
SAFETY CONSIDERATIONS
1. Installation and servicing of air conditioning equipment can be hazardous due to system
pressure and electrical components. Only trained and qualified personnel should service
equipment.
2. When working on air conditioning equipment observe precautions in the literature and
labels attached to the unit and other safety precautions that may apply. Follow all safety
codes. Wear safety glasses and work gloves. Use quenching cloth for brazing operations.
Have a fire extinguisher available for all brazing operations.
WARNING!
Before performing service or maintenance operations on the system, turn off the
main power switches to the unit. Electrical shock could cause personal injury.
INSTALLATION INITIAL CHECK
1. The carton should not be removed from unit until reaching final location to avoid damage.
2. Inspect unit for shipping damage and file a claim with the transport agency if necessary.
3. Check field electrical works:
a. Proper size of fuses and wire, correct wiring connections and grounding as specified
by the local electrical codes.
b. Also check supply voltage. This must be within the limits shown on the rating plate.
4. Check for a proper condensate flow.
5. Be sure piping insulation is adequate.
6. Confirm there are no obstructions to air flow for the unit. Also check for sufficient
clearances for servicing of the unit.
SELECTION OF THE INSTALLATION LOCATION
1. Unit should be installed for horizontal and vertical discharge application only, as shown in
Fig. 1.
2. There should not be any heat source of steam near the unit.
3. There should not be any obstacles to prevent the air circulation.
4. A place where air circulation in the room will be good.
5. A place where noise prevention is taken into consideration.
6. Ensure the spaces indicated by arrow from the wall, ceiling, fence, or other obstacles.
7. Do not install the unit near the door way.
8. Do not install the unit near a fire alarm.
9. Do not install the unit in a machinery shop or kitchen where oil vapour flows into the unit.
The oil will deposit on the heat exchanger, thereby reducing the unit performance. In the
worse case it may deform or break the plastic parts of the units. It is recommended that the
standard filter be replaced with a special filter if necessary.
