NOTE
Only trained or authorised electricians are allowed to carry out any work
required in the electrical parts of this Cotes dehumidifier.
Ensure the power supply is switched off at the mains switch when the cover
of the electrical box is open.
Commissioning procedure
1. Inspect the electrical installation before starting the dehumidifier and switch on the mains switch:
• 230V – Check the voltage between the terminals L1, N
• Is the ground cable connected, and of the correct specifications?
• Is any hygrostat (if fitted) correctly connected?
2. Check the connected duct system:
• Is the recommended damper installed in the regeneration air outlet duct?
• Is the optional damper installed in the Dry Air Outlet duct?
• 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.
3. Suggested damper positions/air flow settings at commissioning:
• Dampers/settings should be set in the following positions.
o Damper at Dry Air Outlet: Fully open.
o Damper at Regeneration Air Outlet: Fully open.
4. Once the dehumidifier is operating, adjust the potentiometer (if installed) and air flows according to
the values in the table below.
