B) Auto Restart Mode - Auto Restart Mode permits the dryer to start after a brief
delay once power is applied to the dryer. In TECHNICIAN MODE, changing the
Auto Restart parameter from the default “N” to “Y” using the SET button enables
this mode of operation. Note that the dryer’s touch pad will still affect dryer
operation. Depressing the OFF button will de-energize the refrigeration
compressor and all other electrical components. After the OFF button has been
depressed, the user must depress the ON button to permit the dryer to operate.
C) Remote Mode - Remote Mode allows the dryer to be turned ON or OFF via a
remote switch supplied by the customer. This mode will work regardless of the
setting for Auto Restart. The dryer must be powered on for this feature to take
effect. To enable this feature:
• Install N.O. remote switch as indicated on the appropriate wiring diagram.
• Customer-supplied contact should be rated at 1A at 24V. To operate dryer,
close switch or contact and allow dryer to start after an initial delay. The
local On / OFF pushbuttons may also be used at any time after contact
closure.

7.5 INITIAL START-UP
For water cooled models, the water valve must be manually opened
to ensure that the condenser is full of water prior to start-up.
7.5.1 START- UP SEQUENCE
• Apply power to dryer. LCD Panel will illuminate. The Anti-Short Cycle delay will
commence counting down. Remaining time on the Crankcase heater will also
countdown.
After installation or a prolonged shutdown, start the dryer with no air load (no air flow).
This enables the dryer to reach its proper operating temperature in the shortest time
possible (typically within 30 minutes for HeatSink™ dryers).

NOTICE
Allow 8 hours of warm-up time for the crankcase heater prior to start up.
