FEATURES AND BENEFITS (CONT.)
External Service Valves
Service valves are brass, front seating type. The 38YCC has sweat
field connections. Valves are externally located so refrigerant tube
connections can be made quickly and easily. Each valve has a
service port for ease of checking operating refrigerant pressures.
Easy Serviceability
One panel provides access to electrical controls. Removal of wire
dome gives access to fan motor and removal of the top gives access
to the coil and compressor. All models are equipped with a
compressor terminal plug.
Discharge Muffler
Minimizes low frequency sound and pressure pulsation generated
by compressor discharge gas.
Defrost Control Board
This board incorporates a built--in 5-- minute compressor
time--delay relay, defrost relay , defrost timer, and low--voltage
terminal board. The defrost control is a time/temperature initiation/
termination control which includes 4 field--selectable (DIP switch)
time periods of 30, 60, 90, and 120 minutes. This control also
includes a field selectable (DIP Switch) Quiet Shift defro st mode
which, if selected, maintains extremely quiet operation during
defrost.
