completed during start-up and sent to Trane. This
checklist should be used as a guideline for items
that need to be confirmed during start-up.
Test cooling operation by adjusting the temperature

Operational Description
When used with a Trane indoor evaporator unit, the A/C
system compressor starts then the condenser fan(s) start.
Operation of the condenser fans is dependent on the head
pressure control method used.
Remote air-cooled condensers may
be configured for
stan
d-alone operation. In this case the fans begin
operating when power is turned on.
Refrigerant flowing from the evaporator
in the form of a
low pressure gas, enters the compressor where it is
compressed into a high temperature, high pressure gas.
