IMPORTANT NOTICE
Dantherm Ltd. 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.
The machines described in this manual are specifically designed for
heating potable water. The heat pumps use R134a as a refrigerant and
operate in air temperatures from 7ºC to 50ºC providing heated water to
68ºC.
As an option AW3034 and AW7034 machines are available with reverse
cycle defrost which allows the heat pumps to operate in temperatures
down to -15ºC.
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 6 minute cycle time delay is incorporated. The units
are weatherproof and can be installed either outside or within a ventilated
plantroom (as detailed in section 1 of this manual).
A 12 hour delay timer is incorporated into 3034 and 7034 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.
