7. Mounting

 

Always disconnect the power supply before opening the unit.

Heat load to be dissipated from enclosure should not exceed specific cooling output of the unit at any condition. When 

selecting a cooling unit, always allow for a safety margin of at least 15% extra cooling output in the worst conditions. Air 

inlets and outlets must be completely free from obstruction.

Ensure that flows of air leaving and entering the cooling unit, internal and external, are not obstructed. Cooling unit enclosure 

air suction hole must be installed at the highest possible point. When installing the unit on a door ensure it can take the 

weight.

Before  drilling  the  enclosure,  ensure  the  fixing  elements  and  couplings  will  not  interfere  with  the  equipment  inside  the 

enclosure itself. Disconnect power before starting any work inside the enclosure. Following this 1:1 Scale Drilling Template, 

drill the holes and make the required cuts on the enclosure. This template may have been affected by storage conditions, 

please check this template by verifying values of the largest dimensions before drilling. Fit the sealing strip to the cooling 

unit on the side connected to the enclosure and follow the installation diagram.
