The Healthy Climate® PureAir® air purification system (PCO20−28) may be used with 15GCSX units installed in horizontal air discharge applications only. Installation hardware kit (Y0629) is required to install the PCO20−28 (X8787) in the packaged unit. The PCO20−28 is designed for universal voltage, and is ready to operate at 208/230V. When used, the PCO should be installed before the unit is set in place and before the duct connections are made.

Supply & Return Duct Connections

The duct system should be designed and sized according to the methods in Manual Q of the Air Conditioning Contractors of America (ACCA).

A closed return duct system shall be used. This shall not preclude use of economizers or outdoor fresh air intake. It is recommended that supply and return duct connections at the unit be made with flexible joints.

The supply and return air duct systems should be designed for the CFM and static requirements of the job. They should NOT be sized by simply matching the dimensions of the duct connections on the unit.

CAUTION

When fastening duct system to side duct flanges on unit, insert screws through duct flanges only. Do not insert screws through casing. Outdoor duct must be insulated and waterproofed.

The 15GCSX unit is shipped ready for horizontal air discharge (side duct connections). If bottom air discharge is desired, the covers must be removed from the supply and return air openings on the bottom of the unit and re−installed to cover the side openings.

The upper return air opening cover must be removed when the PureAir® air purification system (PCO20−28) is being used. In PCO applications, both upper and lower return air openings must be covered by the return air plenum to ensure proper PCO operation. The upper return air opening is not required in horizontal applications when the PCO is not used.
