Installation
Unless otherwise requested by the customer at the time of shop drawing approval, the cabinet insulation is
left intact, covering the supply air openings and, if applicable, the secondary return air opening. The reasons
for this are:
•
To provide a measure of protection from wind, driven rain or snow entering the unit before the
windows are installed.
•
To prevent construction dust entering the unit.
The installer is responsible for cutting out the insulation and buttering the cut edge prior to installing the
grilles.
Remove the inlet service panel and check the fan wheel for free rotation by spinning it manually. Slight
misalignment can be corrected by repositioning the motor or by loosening the fan hub set screw and
repositioning the fan on the motor shaft.
Use solder to connect the risers. Do not use Silfos (brazing) as this will cause the pipe to overheat and
the insulation to be damaged.
Ensure that the horizontal run-out from each riser is centered in the
slot in the cabinet and that the run-out from the riser is at 90º as it enters the cabinet, prior to
soldering the risers. Anchoring the risers to the floor slabs is the responsibility of the contractor.
Shim the unit plumb. It is not necessary to use a pad under the unit. Fire stopping the floor opening and
making good the riser insulation at the floor opening is the responsibility of the contractor. Check that
the drain hose is not kinked before soldering the condensate riser. If the risers incorporate expansion
compensation loops, remove the support brackets after anchoring the risers.
The fan coil unit has unions at the shut off valves. These fittings must be checked prior to pressure
testing the system by the contractor as part of the installation procedure. Mechanical fittings can
loosen during transportation and handling. If contractor /installer deem it necessary to tighten mechanical
fittings Temspec does not assume any responsibility for this procedure.
It is stressed that the component
manufacturer's recommended procedures be strictly followed
.
The coil is pressure tested hydrostatically at the factory using a propylene glycol solution. Trace amounts of
this solution are allowed to remain in the coil to ensure that the coil does not freeze during
transportation. After testing on site with water the fan coil unit must not be exposed to freezing temperatures.
The interior of the unit must be vacuumed clean before the unit is started up. This includes fan motor
windings.
Accessories
Do not install grilles or thermostats until after the walls have been painted. Caution the painter
against spraying over the labels on the front cover of the unit.
