Be aware that certain components such as the refrigerant compressor and the discharge pipe can
become quite hot (up to 110 °C - 230 °F). Therefore, wait until the dryer has cooled down before
removing the panels.
Before starting any maintenance or repair work, switch off the voltage and close the air inlet and outlet
valves.

If the compressor work cycle contemplates long pauses during which the machine cools down, a certain
amount of condensate will gather in the Oil tank. This happens, for example, when stopping overnight or
at weekends.
The condensate must be drained off every 50 hours or every week for continuous running machine. (
More than 50 % load).
The condensate must be drained daily for unit running less than 50% or running on intermittent operation.
Note – The above operation should be performed only when the machine is cold, that is when it has been
switched off for atleast 4 hours.
Condensate drain once in a week from gear casing.
