Section 4: Installation
4.1 Installation Precautions
To ensure that the installation is performed correctly
carefully follow the instructions indicated in this manual.
Failure to follow instructions indicated not only can cause
malfunctions of the appliance but also void the warranty.
It is important that the electrical installation is made in
accordance with local codes, respects the data indicated
in the technical sheet and is correctly earthed.
The appliance must be installed in a position that allows
for routine maintenance, such as lter cleaning.
The system inlet water temperature must not exceed
160°F. Failure to comply can severly damage the unit and
will void the warranty.
4.2 Positioning the Unit
Avoid installing the unit in close proximity to:
-positions subject to exposure of direct sunlight
-in proximity to sources of heat
-in damp areas or places with probable contact with water
-in places with oil fumes
-places subject to high frequencies
Make sure that:
-the wall on which the unit is to be installed on is strong
enough to support the weight
-the part of the wall being used does not have pipes or
electric wires passing through
-is free of obstacles which could interfere with the inlet
and outlet air ow
-is preferably an outside perimeter wall to allow the
discharge of condensation outside.
4.3 Minimum Clearances
