Adjustment
NOTE:
Adjust the tharmostat to settings specified by the
manufacturer of the controlled equipment. When
checking thermostat operation, or operating
the controlled equipment, do not exceed the
manufacturer’s temperature ratings for the controlled
equipment or for any of its components.
To avoid inaccurate thermostat operation, do not
adjust the KPU’s pointers beyond the highest or lowest
indicator marks on the scale plate.
Before adjustment loosen the locking screw.
For setting use Universal Refrigeration Wrench or the setting
knob, if available. Movement of the setting knob is limited
by the locking screw, which allows only small corrections to
the settings. Therefore, if the setting knob is to be used for
adjustments, completely remove the locking screw. After
adjustment, tighten the locking screw.
Manual switch
Available only on KPU 61 (060L5210) and KPU 62 (060L5207),
the manual switch is a two-position switch used to shut down
the refrigeration system. The two positions are:
1.
AUTO: position for automatic operation.
2.
STOP: contacts 1 and 2 are locked in the closed position.
CAUTION:
The manual switch only stops automatic operation,
and can only be used for service on non-electrical
parts. Interrupt mains power before servicing
electrical parts.
Adjustment: thermostat with automatic reset
Scale plate directly indicates High Switching Point
and Differential.
Adjustment: thermostat with manual reset
Scale plate directly indicates Low Switching Point, which is
Cut-Out. There is no pointer for Differential.
Differential value is fixed and printed on the scale plate.
1.
Set High Switching Point by
adjusting range screw. Turn the
screw clockwise to lower the set
point.
2.
Then set Differential by adjusting
differential screw. Turn the screw
clockwise to increase Differential.
3.
Low Switching Point is equal
to High Switching
Point less Differential:
LOW = HIGH - DIFFERENTIAL
1.
Set Cut-Out (Low Switching Point)
by adjusting range screw. Turn
the screw clockwise to lower
the set point.
2.
High Switching Point (Cut-In)
equals Low Switching Point
(Cut-Out) plus Differential:
CUT IN = CUT OUT + DIFFERENTIAL
IMPORTANT:
The scale plate is only for reference and for more
precise setting a temperature gauge should be used.
IMPORTANT:
After installing and adjusting the thermostat, check
your settings by running the controlled equipment
several times (at least three times) under normal
operating conditions.
