Unit Location

Unobstructed condenser airflow is essential to maintaining capacity and operating efficiency. When determining unit placement, give careful consideration to assure sufficient airflow across the condenser coils. Avoid these two detrimental conditions: warm air recirculation and coil starvation.

Both warm air recirculation and coil starvation cause reductions in unit efficiency and capacity because of the higher head pressure associated with them. In more severe cases, nuisance unit shutdowns will result from excessive head pressures.

Clearance

Ensure vertical condenser air discharge is unobstructed. While it is difficult to predict the degree of warm air recirculation, a unit installed with a ceiling or other obstruction above it will experience a capacity reduction that will reduce the maximum ambient operation limit. Nuisance high head pressure tripouts may also occur.

The coil inlet must also be unobstructed. A unit installed closer than the minimum recommended distance to a wall or other vertical riser will experience a combination of coil starvation and warm air recirculation. This may result in unit capacity and efficiency reductions, as well as possible excessive head pressures. Reference the service clearance section on page 93 for recommended lateral distances.

Ambient Limitations

Standard ambient control allows operation down to 45 F (7.2 C) with cycling of condenser fans. Units with the low ambient option are capable of starting and operating in ambient temperatures down to 0 F (-17.8 C). Optional low ambient units use a condenser fan damper arrangement that controls condenser capacity by modulating damper airflow in response to saturated condenser temperature.

Maximum ambient temperature operation of a standard condenser is 115 F (46.1 C). Operation at design ambient above 115 F can result in excessive head pressures. For applications above 115 F, contact the localTrane sales office.
