In case of Economy Mode and Hybrid Mode, if the evaporating steam freezes in cold
environment, the appliance defreezes it automatically, to ensure efficient
performance (3~10 min).
b) External environmental temperature
The operation temperature of the appliance should be within the interval -30~43 °C
and the operation temperatures of the modes are described below in details.

Explanation of water heating operation

Economy Mode: -7~43°C
1)
This mode is recommended when the external environmental temperature is
between -7~43°C . If the external environmental temperature falls under the
temperature of -7°C, energy efficiency becomes low, evidently, thus it is
recommended to use E-heating mode under these circumstances.
Hybrid Mode: -30~43°C
2)
E-heater Mode: -30~43°C
3)
In each case, only water located in the upper part of the tank is heated, which
means. approximately 100
4.5.

Mode selection

As different modes have been developed to serve different needs, it is recommended
to consider the following: .
⋅ Economy Mode:-7~43°C,
In case of continuous hot water need under 300 L (60 °C);
⋅ Hybrid Mode: -30~43°C,
In case of continuous hot water need between 300 L (60°C).
⋅ E--heater Mode: -30~43°C,
In case of continuous hot water need under 100 L (60°C).

Construction features

4.6.
HB300 heat pump water heater is basically composed of an upper part
(Figure 2.7.-1.) containing heat pump equipment and a lower part (Figure 2.7.-2.)
containing the storage tank. The storage tank of the sanitary hot water- having a
volume of – is covered by an enamel coating internally and by a thick polyurethane
insulation layer having large efficiency externally, and the latter is covered by plastic
surface of the appliance. The pipe radiator, controlling indicator anode electrics and
magnesium indicator anode located on the closing cover are placed on a horizontal
axle common with the closing cover.
The condensate water discharge pipe branch is located in the rear part of the
circle-shaped tray above. The control panel equipped with display is located in the
front part. All the other parts of the heat pump circuit are located above the storage
tank according to a precisely planned order, which produces optimal operation,
reduced vibration and noise emission.
The following parts are placed under an easily accessible and adequately
insulated plastic coverage: compressor, thermostatic expansion valve, evaporator,
fan ensuring adequate air flow and all the other parts displayed on Figure 2.7.-1.
