The minimum clearances for the unit are illustrated in Figure 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.
.3.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:
