DESCRIPTION

®These completely assembled units include a well-insulated cabinet, a DX cooling coil with copper tubes and aluminum fins, expansion valve(s), distributor(s), throwaway filters, a centrifugal blower, a blower motor, an adjustable belt drive, a blower motor contactor and a small holding charge of refrigerant-22.

The units are shipped in the vertical position ready for field installation. They can be installed for horizontal operation by reversing the position of the solid bottom panel with the return air duct flange on the front of the unit.

ACCESSORIES—FIELD INSTALLED

SUPPLY AIR PLENUMS

These fully insulated plenums are available for free standing units located within the conditioned space, are shipped knocked-down for easy field assembly, are finished to match the exterior of the basic unit, and have double deflection grills that can be adjusted to vary the throw, spread and drop of the supply air.

RETURN AIR GRILLS

These expanded metal grills are available for free standing units located within the conditioned space, are finished to match the exterior of the basic unit and are shipped in one piece for easy installation.

BASES

Bases are available to raise vertical units above the floor. Outdoor air may be introduced through these bases by cutting an access opening to accommodate the outdoor air duct connection. These bases are fin- ished to match the exterior of the basic unit. They may have to be insu- lated in the field for certain applications.

THREE-PHASE ELECTRIC HEATERS

Electric heaters are available in several capacities to provide maxi- mum flexibility. Both the air conditioning unit and the heater can be selected to precisely match the cooling and heating requirements of the conditioned space. These heaters are designed for easy field installation over the supply air opening of the unit. They have been tested by and will be shipped with a CSA label. Every heater will be fully protected against excessive current and temperature by fuses and two high limit thermostats.

Units with electric heat will require only one power supply for both the heating elements and the supply air blower motor, and the power wir- ing can be protected by either dual element/time delay fuses or an inverse time circuit breaker.
