1. Refer to the unit wiring diagram. Identify the liquid-line solenoid valve
and CLP switch associated with the circuit being adjusted.
NOTE: If the unit model number ends in “2”, e.g. DS042, there will be
two
refrigeration circuits, with two
sets of components.
If the unit model number ends in “4”, e.g. DS284, there will be
four
refrigeration circuits, with four
sets of components.
If the unit model number ends in “8”, e.g. RS488, there will be
eight
refrigeration circuits, with eight sets of components.
2. In the unit control enclosure, remove the temporary jumper across the
pressure switch labeled “CLP” as shown. Where more than one
refrigeration circuit is present, be sure to identify the correct CLP
switch.
3. Close all covers.
