AIR VENT AND WATER PURGE VALVES
1. After connecting the water inlet and outlet pipes to the main supply lines turn on the main breaker and operate
the unit in COOLING mode. The high-wall unit should be mounted on a solid wall.
2. Open the water inlet valve and flood the coil.
3. Check all connections for water leakage. If no leak is found, open the purging valve with an open end wrench while
supporting the unit with your other hand then purge the air trapped inside the coil. When performing this activity,
take care not to touch the electrical parts.
4. Close the purging valve when no bubbles appear.
5. Open the water outlet valve.
MOUNTING DETAIL
Select the location for the high-wall unit with the following considerations:
1. The air inlet and outlet area should be clear without obstructions. The air should flow freely.
2. The high-wall unit should be mounted on a solid wall.
3. The location should allow easy access to connect water pipes easily to achieve drainage.
4. Ensure the clearance around the fan coil unit conforms to the following drawing.
Notes for above diagram:
•
Required clearance for maintenance and servicing is as shown above.
•
All dimensions shown in mm.
5. The unit should be installed higher than eye level.
6. Avoid installing the unit where it will be in direct sunlight.
7. The signal receiver on the unit must be kept away from any high frequency emission source.
8. Keep the unit away from fluorescent lamps, which may affect the control system.
9. Avoid electromagnetic control system interference, ensure control wires are installed separately from 110-240 VAC
power supply wires.
10. Use shielded sensor cables where electromagnetic waves are present.
11. If electrical noise is present, the use of an approved electrical noise filter is suggested.
