Adjustment
NOTE:
Adjust the temperature control to settings specifi ed by
the manufacturer of the controlled equipment. When
checking temperature control 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 control 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.
Adjustment: Temperature Control with automatic reset
Scale plate directly indicates High Switching Point and
Diff erential.
3. Low Switching Point is equal to High Switching Point less
Diff erential: LOW = HIGH - DIFFERENTIAL

1. Set High
Switching Point
by adjusting
range screw.
Turn the screw
clockwise to
lower the set

Adjustment: Temperature Control with manual reset
Scale plate directly indicates Low Switching Point, which is
Cut-Out. There is no pointer for Diff erential.
Diff erential value is fi xed and printed on the scale plate.
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 Diff erential:
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 temperature control,
check your settings by running the controlled equipment
several times (at least three times) under normal operating
conditions.
Manual switch
Available only on KPU61 (060L5210) and KPU62 (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.
