Normally, the unit is installed outdoors either on the roof or ground, where practical. In normal roof installation, the unit is placed on an angle iron frame, and where required in some instances, isolated from the frame with rubber, cork or spdng mounts. These mounts are to help eliminate vibration and noise. Ground installation is basically the same for both self-contained units and split-system outdoor -units. Locate the unit on a concrete slab or blocks not connected to the buildingsfoundation. Allow adequate clearance for service and air intake and discharge. The unit must be level in order to assure proper condensate drainage, and the gravity flow condensate line should be a minimum of 314 inch

I.D. diameter and be properly graded. Loosen the compressor mounting bolt_tO ensure that the compressor is resting on the rubber grommets and not on the metal sleeves.

The actual amount of total refrigerant charge for each installation may have to be adjusted to insure that unit performance characteristics (compressor electrical current draw, suction and discharge pressures) are consistent with those given in the application tables for the applicable ambient conditions.

It is extremely important that a condensate "P" trap be installed in the drain line below the bottom of the unit, as shown in the sketch below.

Apart from ensuring proper drainage, the condensate trap will prevent the hot and humid outside air

from being drawn into the conditioned space through the drain line, thus reducing cooling and dehumidification of the unit.
