Air/water heat pumps
Important Note
Calorex heat pumps Limited is an ISO9001:2000 certified company.
All Calorex heat pumps are CE approved. Heat exchangers within the heat pumps are compliant to WRAS (British Water
Regulation Authority Standards) and listed under UL standards.
Models covered in this manual
The machines detailed in this manual are specifically designed
for heating potable water. The heat pumps use R134a as a
refrigerant and operate in air temperatures from 7°C to 55°C
providing heated water to 68°C.
As an option, machines are available with reverse cycle defrost
which allows the heat pumps to operate in temperatures down
to -15°C.
All units are supplied as a package and have integral safety
devices to protect the heat pump from internal and external
faults. Indicator lamps indicate operating mode. An adjustable
thermostat controls water temperature. Also a six minute cycle
time delay is incorporated. The units are weatherproof and can
be installed either outside or within a ventilated plant-room (as
detailed in section 1 of this manual).
A 12 hour delay timer is incorporated into machines, which
after a power interruption or from initial start up will prevent the
machine compressor(s) from starting for a 12 hour period. This
feature is to protect the compressors from liquid pumping which
can cause internal compressor damage.
