5.3 INSTALLATION: SITING, PLUMBING & ELECTRICAL.
Great care should be exercised in following the installation procedure to ensure
that your Calorex dehumidifier performs as it was designed.
5·3.1 SITING.
a. Ensure dehumidifier on site is as ordered, i.e. model, electrical supply and
factory fitted option.
b. Inspect unit for damage, in particular inspect the evaporator (finned side)
to ensure that it is undamaged. (Minor indentations in the fins do not affect
performance). If severely damaged, endorse delivery note in presence of the
driver and send a recorded delivery letter to transport company giving details.
c. Protect unit if installation is delayed.
d. Provide a firm level base capable of supporting operational weight of unit;
spread load if on timber floor.
e. Ensure water cannot collect under unit, recommend units are installed on
plinths 100mm above finished floor level and to also aid condensate drainage.
f. Allow adequate clearance to service panels on unit; recommend 500mm
minimum (see installation drawings).
g. All Calorex dehumidifiers are by design as quiet as is practicable, however,
due consideration should be given to siting in order to fully exploit this feature,
i.e. orientate inlet/outlet parallel to occupied premises.
h. Ensure loose debris will not block air inlet filters or grilles.
5.3.2 DEHUMIDIFICATION AIR FLOW
Due consideration must be given to air flow, ie. do not obstruct inlet or outlet
ducts and ensure discharge air cannot re-circulate to inlet (see below)
Grille or Apertures MUST comply with the following minimum free area:
Inlet
0.56 m²
Discharge
0.2 m²
Required Free Area to provide air flow to and from heat pump when installed
in an enclosed area or where required to pass air through a wall, etc.
Note: if multiple units are installed in an enclosed area then the inlet free areas
required for each unit can be added together to form one inlet aperture BUT
discharge from each unit must be kept separate and not be incorporated into
one common duct system.
