8.4.UNIT CLEARANCES
Fig. 8.--1
The minimum clearances for the unit are illustrated in
Fig. 8--1
. Condenser air enters from
three sides. Air discharges upward from the top of the unit. Refrigerant tube and electrical
connections are made
from the service access area. The most common application will find the unit best located
about 10" from back wall with connection side facing the wall. This application minimizes
exposed tubing and wiring, minimizing the space for youngsters to run around the unit with
subsequent damage to the tubing or wiring.
In more confined application spaces, such as corners provide a minimum of 10" clearance
on all air inlet sides. For service access to the compressor and control box, allow 18"
minimum clearance. Ensure top is unobstructed. If units are to be located under an
overhang, there should be a minimum of 36" clearance and provision made to deflect the
warm discharge air out from the overhang.
In order to have an unrestricted air flow, owners should be advised to avoid lawn mower
discharge toward the unit depositing debris on the fin coil surface reducing the unit
efficiency.
8.5 REFRIGERANT PIPING
The refrigerant piping is very important as it affects the proper operation and efficiency of
the air conditioning system. Note the following guidelines:
1. The total run ,both vertical and horizontal ,can’t be exceed 50 feet
2. Use the next larger liquid line size if the vertical separation exceeds 10 feet.
