Start Up Procedures

There should be NO air flow through the dryer before or during start-up. It is recommended that
the dryer be installed with bypass piping to better service the unit. Inlet & outlet valves to the
dryer should be closed with the by-pass valve open.
1. After electrical connection (Section 2), apply power.
2. Leave power on for 8 hours before attempting to start (POWER light on). This allows the
crankcase heater time to warm the refrigerant compressor oil and dissipate any refrigerant
migration that can occur during storage. Failure can result in damage to the compressor
and will void the warranty.
3. Verify suction pressure gauge reads above 80 psi (5.5 bar). If it is less, the dryer may have a
refrigerant leak. This may be the result of shipping damage – see section 1.0.
4. Switch unit on. ON/OFF indicator will light.
5. Do not pass air through the dryer until it stabilizes (Typically 5 minutes).
6. Once the dryer stabilizes, you can now introduce compressed air to the dryer.
SLOWLY pressurize the dryer. Once completed slowly open the outlet valve, then close the
bypass valve. The dryer is now on line.
7. Clean the condensate drain strainer after the first 8 hours of operation.
(See section 5.0 Routine Maintenance)
8. Restart dryer using this procedure after maintenance, power outage or prolonged periods of
shutdown.
