HOW TO COMMISSION THIS DEHUMIDIFIER
Procedure
a) Check the electrical installation before starting the dehumidifier, switch on the mains
switch.
• Check the voltage between the terminals L1, L2, L3 (= 400V or 230V for 3 x 230V
dehumidifiers)
• Check one of the phases and Neutral (= 230V)
• Is the ground cable connected, and of the correct specifications?
• Is any hygrometer (if fitted) correctly connected?
b) To check the connected duct system
• Is the recommended damper installed in the regeneration air outlet duct
(Configuration-A only)
• Is the recommended damper installed in the process air outlet duct
(Configuration-A and Configuration-B only)
• Do the regeneration air outlet ducts drain away from the dehumidifier, to make sure that any
condensed water flows away?
• If the regeneration air outlet does not drain away from the dehumidifier, check whether there
is a 6mm-diameter hole drilled in the lowest part of the duct, so that any accumulated water
can drain away.
c) Suggested damper positions/air flow settings at commissioning
Dampers/settings should be set in the following positions.
• Configuration-A:
o Damper at process air outlet: Fully open.
o Damper at regeneration air outlet: Fully open.
• Configuration-B:
o Damper at process air outlet: Fully open.
o Regeneration air fan speed 80%
• Configuration-C and Configuration-D:
o Process air fan automatically adjusts to pre-set air flow (no damper needed)
o Regeneration air fan automatically adjusts to pre-set air flow (no damper needed)
NOTE
Only trained/authorised electricians are allowed to carry out any work required in the
electrical box of this Cotes dehumidifier.
