Mounting Instructions
The unit rating plate lists a “Maximum Time Delay
Relay Fuse” or circuit breaker that is to be used with
the equipment. The correct size must be used for
proper circuit protection and also to assure that there
will be no nuisance tripping due to the momentary
high starting current of the compressor motor.
The disconnect access door on this unit may be
locked to prevent unauthorized access to the
disconnect. To convert for the locking capability,
bend the tab located in the bottom left hand corner of
the disconnect opening under the disconnect access
panel straight out. This tab will now line up with the
slot in the door. When shut, a padlock may be placed
through the hole in the tab preventing entry.
See Start Up section for information on three phase
scroll compressor start ups.
