Introduction

McQuay offers the most complete line of PTAC and PTHP products for new construction projects and exact replacements for our original Singer, Remington, American Air Filter and American Standard brand equipment, and models from other manufacturers.

McQuay products feature our proven institutional grade design and construction that allows you to benet from the long life, reliability, and low sound levels, along with higher energy efciencies for lower operating costs. Plus, McQuay offers a nationwide network for original equipment replacements with local parts and service.

McQuay Conditioners and Heat Pumps are designed and built for through-the-wall installation in either new or existing buildings. The self-contained refrigerant system delivers cooling to the desired space. Heating can be accomplished with electric resistance, with hydronic (water or steam), hydronic with intermediate electric resistance or with reverse cycle technology (heat pump models only). Generally, an estimate for capacity selection is 35 BTUH per square foot of oor space (cooling) and 4 BTUH (1.25 watts) per cubic foot (heating). The architect or engineer must verify the selection. Note that the heat pump reverse cycle generates approximately 10 BTUs per electrical watt as compared to 3.4 BTUs per watt with resistance electric heat. The unit will restart at its last setting after

a power interruption.

Panel Wall Construction Type

For panel wall and thin wall construction, it is recommended that a louver frame be used (See Louver Frame Installation For Thin Wall Types on page 11, and gures 19, 20 & 21).

Panel wall and thin wall construction varies only slightly from frame and brick construction.

Note: The center of gravity is 10" (260mm) from the rear face of the wall sleeve. The wall sleeve must be inserted into the wall at least 10" (260mm) or other support must be employed.

Support can be from a factory supplied subbase or from other eld supplied materials. Installation for this application is as follows (Figures 19, 20, & 21).

1. Clean the opening of all debris that may interfere with installation.

2. If the unit is to be supplied with a subbase, install subbase before installing wall sleeve (see IM 936).

3. If the optional drain kit is to be employed, see IM

942.

4. Be sure the wall sleeve is mechanically attached to the wall and caulked to assure a proper seat. It is recommended that the louver frame be used for

this purpose.
