Why is my Parker Dehumidifier not turning on (no lights)?
Your Parker Dehumidifier might not be turning on because of a blown control fuse (replace the fuse), no power supply (apply correct power), or an inoperative solid state controller (replace the controller).
What to do if Parker Dehumidifier has excessive pressure drop?
If your Parker Dehumidifier has an excessive pressure drop, the pre-filter is likely dirty (replace the element), the afterfilter is dirty (replace the element), or the desiccant is dirty (replace the desiccant).
What to do if Parker Dehumidifier lights are on, but the dryer doesn't switch?
If the lights are on but your Parker Dehumidifier isn't switching, it could be due to a control air shutoff (open the valve), the dryer being in PowerLoc, CycleLoc, or ProPurge mode, or the dryer not being in a 100% load cycle (check the setting). For PowerLoc, CycleLoc, or ProPurge modes consult pages 9-10.
How to fix excessive air loss on the regenerating tower of Parker Dehumidifier?
Excessive air loss on the regenerating tower of your Parker Dehumidifier could be due to: * Purge set too high (check specifications and adjust). * Repressurization solenoid leaking (repair or replace). * Inlet valve leaking or not functioning (repair or replace). * Leaking or inoperative control solenoid (repair or replace). * Defective controller (repair or replace).
Why Parker Dehumidifier unit does not fully repressurize?
If your Parker Dehumidifier unit does not fully repressurize, it could be due to a purge rate that is too low (adjust purge), leaking exhaust valves (see above), a faulty repressurization solenoid (replace solenoid), or a plugged purge or repressurization orifice.
How to eliminate back pressure in regenerating tower in Parker Dehumidifier?
To eliminate back pressure in the regenerating tower of your Parker Dehumidifier, you should check for clogged mufflers (clean, repair, or replace), leaking check valves (clean, repair, or replace), a purge flow that is too high (adjust), or no output from the controller (replace fuse or controller).
What causes inlet or exhaust valves not functioning in Parker Dehumidifier?
Inlet or exhaust valves not functioning on your Parker Dehumidifier can be caused by bad diaphragms or O-rings (rebuild valves available kits or replace), no control air (see below), defective control solenoids (repair or replace), or no output from the controller (repair or replace).
What to do if the exhaust valve on drying or repressurizing tower is leaking in Parker Dehumidifier?
If the exhaust valve on the drying or repressurizing tower of your Parker Dehumidifier is leaking, it could be because the valve is dirty (clean valve), the diaphragms or O-rings are defective (repair or replace), or the control solenoid is leaking (repair or replace).
How to troubleshoot no control air at inlet or exhaust valves in Parker Dehumidifier?
If there's no control air at the inlet or exhaust valves of your Parker Dehumidifier, check if the control air shutoff valve is closed (open it), the control air filter is dirty (replace element), there's a leak in the control air tubing (repair), the control solenoid is defective (repair or replace), or there's no output from the controller (replace fuse or controller).
What causes Parker Dehumidifier failure to switch?
A failure to switch in your Parker Dehumidifier can be caused by a time delay setting that is too short (adjust properly, Failure to Switch option only!). It may also be related to the dryer not operating (see above).
