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.
Protect unit if installation is delayed.
The heat pump is supplied with accessories which aid installation. On delivery the
accessories are in a plastic bag in the heat pump electric box. (See section 4.2
for lid removal).
These accessories are as follows:
4 x rubber feet - Fit these under the metal feet of the heat pump to help reduce the
effects of vibration.
2 x 50mm female connectors - On delivery the heat pump has 1 1/2” sockets
attached to the water connections for fitting 1 1/2” plastic pipes. If 50mm
pipework is preferred undo the threaded couplings on the water in/out connection
points and carefully remove the 1 1/2” sockets. Then fit the 50mm sockets in
their place and refit the threaded couplings. The heat pump can then be fitted
with 50mm plastic pipe.
2 x Condensate drain piece - Condensate drain pieces are supplied suitable for 3/4”
or 20mm pipe. Use whichever piece fits the drain pipe required. Glue the relevant
piece to the driptray outlet and then fit then condensate drain piping.
a) Provide a firm level base capable of supporting operational weight of unit; spread
load if mounted on timber floor.
b) Ensure water cannot collect under unit, it is recommend that units are installed
on plinths 100mm above finished floor level. This also aids condensate drainage.
c) Allow adequate clearance to service panels on unit; recommend 500mm
minimum.
d) All Calorex heat pumps are by design as quiet as is practical, however due
consideration should be given to siting the heat pump in order to minimise the
noise coming from the machine, for example by positioning the machine so that
the inlet/outlets are parallel to occupied premises.
e) Ensure loose debris such as leaves, grass cuttings, etc will not block air inlet
grilles.
f) Consider protection from extreme weather conditions if installed externally, i.e.
lean-to-cover or building.
