Start Up Procedures
There should be NO air flow through the dryer before or during start-up. It is recom-
mended 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. This allows the crank
case heater time to warm the refrigerant compressor oil and dissipate any refriger-
ant migration that can occur during storage.
3.
Verify suction pressure gauge reads above 80 psi (bar). If it is less, the dryer has
a refrigerant leak, (see “A3” in trouble shooting section). This may be the result of
shipping damage – see section 1.0.
4.
Switch unit on. ON/Off indicator will light green when unit is running.
Do not pass air through the dryer until it stabilizes and cycles off (Typically 15-25
minutes).
5.
Once the dryer cycles off, you can now introduce compressed air to the dryer.
6.
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 Y-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.
4.1
When Operating Dryer
1. Turn dryer On and Off at control panel only.
2. Keep power to unit at all times except when servicing.
3. Start dryer prior to allowing air flow through unit.
4. Clean condenser when necessary.
5. Maintain ambient temperature between 41-100ºF (5-38ºC)
6. Keep inlet temperature under 101ºF (38ºC)
7. Check and clean Y-strainer regularly.
8. NEVER allow dryer to cycle ON/OFF with air compressor.
