Danfoss R22 User Manual

The temperature inside the terminal box may not
exceed 158°F. Consequently, if the compressor
is installed in an enclosure, precautions must be
taken to avoid that the temperature around the
compressor and in the terminal box would rise
too much. The installation of ventilation on the
enclosure panels may be necessary. If not, the
electronic protection module may not operate
properly. Any compressor damage related to this
will not be covered by Danfoss warranty. In the
same manner, cables must be selected in a way
to insure that terminal box temperature does not
exceed 158°F.

Three phase electrical characteristics
Locked Rotor Amp value is the higher current as
measured on mechanically blocked compressor
tested under nominal voltage. The LRA value
can be used as rough estimation for the starting
current. However in most cases, the real starting
current will be lower. A soft starter can be
applied to reduce starting current.
