5.OTHER INSTALLATIONS – Many other installations are possible with the packaged air conditioner. No matter what the installation, always consider the following facts:

A.Insure that the discharge air is not obstructed in any way so as to cause operation difficulties.

B.The indoor coil drain pan is equipped with a coupling that must be piped through a condensate drain trap to a suitable drain.

C.Always mount the unit is such a position that it may be easily reached for servicing and maintenance.

D.Insure that the unit is clear so that proper air flow over the outdoor coil will be maintained.

If this unit is operated in cooling below a 65° outdoor ambient temperature, the installation of low ambient controls (CMA-6) to unit is required.

CONDENSATE DRAIN TRAP

It is very important to provide a trap in the condensate drain line to allow a positive liquid seal in the line and assure correct drainage from the coil condensate pan.

Install condensate drain trap shown in Figure 8. Use drain connection size or larger. Do not operate unit without trap. Unit must be level or slightly inclined toward drain. With a trap installed on a unit located in an unconditioned area, water in the trap may freeze. It is recommended that the trap material be of a type that will allow for expansion of water when it freezes.

AIR FILTERS

Air filters for the return air side of the system are not provided as part of these models, and must be field supplied and installed as part of the final installation.

Prior thought should be given to return air location and placement of the air filter(s). The air filter(s) must be of adequate size and readily accessible to the operator of the equipment. Filters must be adequate in size and properly maintained for proper operation. If this is not done, excessive energy use, poor performance, and multiple service problems will result. It is impossible to oversize air filters. Generous sizing will result in cleaner air and coils as well as lower operating costs and extend the time between required changes. Table 8 shows minimum filter areas and recommended filter sizes. Actual filter sizes can vary with the installation due to single or multiple returns utilizing a filter/grille arrangement or being placed immediately ahead of the indoor coil face in the return air duct.
