a Ensure heat pump on site is as ordered, i.e. model, electrical supply and
factory fitted options.
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 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 heat pumps are by design as quiet as is practical, 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 such as leaves, grass cuttings, etc will not block air inlet
grilles.
i Consider protection from extreme weather conditions if installed externally, i.e.
lean-to-cover or building.
Due consideration must be given to air flow, i.e. do not obstruct inlet or outlet
and ensure discharge air cannot recirculate to inlet. (See figures 1 and 2)
Required Free Areas to provide air flow to and from heat pumps when
installed in an enclosed area or where required to pass air through a
wall, etc.
Free area is the available area through which air can pass through a grille or
louvres.
1. 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 must not be
incorporated into one common duct system.
2. If the unit is installed within a plantroom, connected to ductwork, Dantherm
Ltd. can supply the unit with an uprated fan motor.
Please consult Dantherm Ltd. before ordering a unit.
