IMPORTANT

The electrical connection of the unit must be carried out by 

a qualified electrician. 

For good EMC engineering practice, the power supply output 

cable and any sensor cables should not be placed within 

50mm of other cables or each other.

4.3.3 Dual Inlets

The unit features a dual inlet which automatically selects the air source 
based on the surrounding temperature. To utilise this feature, the 
circular guard needs to be knocked out and the supplied spigot fitted 
(ensure the lose guard is removed from the unit). If ducted air supply is 
not being used, 

do not knock out guard.

Fix the required spigot to the unit with the screws provided and 
seal with silicone to eliminate air leakage.
