Wire the dryer separately from the air compressor. The dryer must not cycle with the air
compressor. Refer to Section 6.0 – Start up Procedure.
Phase rotation is important if the dryer has a 3 phase condenser fan and/or the unit is
equipped with a scroll compressor (SMART CYCLE PLUS 500 – 1200). Fans must pull air
through condenser coil.
Read special TAG on scroll compressors fro proper rotation.
Observe dewpoint reading to verify rotation. If dewpoint reading does not drop within 30
seconds, turn unit off and reverse two electrical leads.
Crankcase heaters are pre-wired at the factory to line side of terminal box or contactor.
Heaters must be energized at all times, therefore the main disconnect must be left on at all
times except when servicing.
