SECTION IV: INSTALLATION
PCP INSTALLATION
INTRODUCTION
Installation requires the unit to be placed on a roof mounted curb, the mechanical room floor, an appropriate location in
the pool room, or outside on an equipment housekeeping pad. Isolation pads should be placed under the unit to minimize
transmission of noise due to unit operation. Then pool water is piped to the unit. Electrical power from a properly sized
fused disconnect is connected to the unit. The supply and return air ducts are connected to their respective locations on
the unit. The condensate is piped back to the pool or to the sewer.
If an optional remote air-cooled condenser is used, place the condenser in a proper outdoor location. Refrigerant
piping is then run from the air cooled condenser to the PoolComPak™ unit. Refrigerant lines must be leak checked and
evacuated through installer provided Schrader valves. Control and power wiring are run to complete the installation.
If a field-furnished auxiliary space heating coil is installed, the control for this heater must be field wired to the
PoolComPak™ controls shown in Section V1 - Wiring (
Figure 6-3, Field Wiring Diagram
).
Outside air can be ducted into the unit through the optional outside air duct connection. The unit can draw up to 30%
of its supply air from the outside. When ventilating the natatorium in this way, an exhaust fan must be furnished in the
natatorium to exhaust to the outside an air volume slightly greater than the air volume introduced into the natatorium
from the outside. This will maintain a negative pressure in the space, preventing odor and moisture migration. Outside
air filters are provided for Horizontal PoolComPak™ units. For Vertical PoolComPak™ units, outside air must be filtered
before entering the unit.
