CONDENSATE DRAIN TRAP

MIS-136

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 7. 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 5

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.

NOTE: If roof hood accessory is to be used,

information on air filters may be found

under that heading in this manual. Air

filters are supplied as part of that package.

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.
