Figure 2 Mounting Instructions - Bard HA4S3 Installation Instructions Manual

The unit rating plate lists a "Maximum Time Delay
Relay Fuse" or "HACR" type 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.
