The HPT300(C) heat pump boiler is basically composed of an upper part (Figure 2.1.-1.)
containing the heat pump unit and a lower part (Figure 2.1.-2.) containing the storage
tank. The storage tank of sanitary hot water – having a volume of (300 l) – is covered
by an enamel coating internally and by a highly efficient thick polyurethane insulation
layer externally, where the latter is covered by the plastic surface of the appliance.
The pipe radiator, limiter, anode indicator electronic unit and magnesium indicator
anode are located inside the heater. The condensate water discharge pipe branch is
located in the rear part of the above circular tray. The control panel with a display is
located in the front part. All the other parts of the heat pump circuit are located above
the storage tank in a precisely designed order that enables optimal operation, and
reduced vibration and noise emission.
The following parts are placed under an easily accessible and adequately insulated
plastic cover: compressor, thermostatic expansion valve, evaporator, fan ensuring
adequate air flow and all other parts displayed on Figure 2.1.-1.
4. USEFUL RECOMMENDATIONS
WARNING
A qualified technician must perform the installation and first start up of the appliance,
in line with the relevant regulations and laws in effect, and any other requirement set
out by the local governments or public health institutions.
If the water heater to be installed does not simply replace an existing appliance, but
it forms part of the renovation of an existing hydraulic system or a new hydraulic
system, the company installing the water heater shall issue a certificate of conformity
to the buyer certifying compliance with all effective regulations and specifications,
after finishing installation of the appliance. In both cases, the company performing
installation has to execute safety and operational testing of the entire system.
Before starting up the hot water tank, please check if the installing technician has
performed all required operations of installation. Make sure that you have properly
understood the information provided by the installing technician on how to use the
hot water tank and how to perform the main operations on the appliance.
