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.
•
Duct to the outside using ridged ducting.
