Installation configurations

4.6.1 Ecological ambient heat recovery

Even on cold days, heat is drawn from surrounding ambient air.
The heat pump will operate at temperatures between a
minimum of -7 °C and maximum of 40 °C. The electrical
element will operate together with the heap pump cycle when
the air falls below 0ºC. The electrical element will operate only
by its own when air temperature is below -7 °C or higher than
40 °C and heating is required. The efficiency of the water
heater increases as the surrounding ambient air temperature
increases.
Automatic safety controls are fitted to the water heater to
provide safe and efficient operation.
Additionally, the heat pump water heater enables direct
connection in series to a second heat generator, e.g. a solar
heating system or a boiler as backup hot water generation
sources.
CAUTION:
▶ Choose the right path to move the unit.
▶ Only move the unit in its original
packaging.
▶ If the unit is installed in a metal building,
proper insulation and compliance with
the relevant technical standards of
electrical equipment is to be provided.

Insulation blanket

If local codes require external application of thermal insulation
blankets kits, the manufacturer's instructions included with the
kit must be carefully followed.
Application of any external insulation, blankets, or water pipe
insulation to this water heater will require careful attention to
the following:
• Do not cover the temperature and pressure-relief valve.
• Do not cover access panels to the heating elements.
• Do not cover the operating or warning labels attached to
the water heater or attempt to relocate them to the exterior
of the insulation blanket.
• Do not block the air inlets/outlets and the top cover.
• Do not cover water heater control unit.

Fill the water storage tank

CAUTION: Damage to the appliance!
▶ Prior to commissioning the appliance,
fill the storage tank with water and purge
tank through hot water piping and
fixtures.
Adjust the purge valve in order to facilitate
the coupling to a draining hose and minimize
any water splash to other components
including the EPP base.
▶ Rotate the gray head (Fig. 13, [3]) of the
purge valve clockwise (tightening) to
adjust it.
▶ Open hot water outlet (Fig. 5, [6]) and one or more hot
water taps.
▶ Open storage tank cold water inlet (Fig. 5, [8]).
Storage tank filling starts.
▶ Close hot water taps only when water flow is free of air
pockets.
▶ With the cold water inlet open and the hot water taps
closed, open the purge valve (at least one complete
rotation, Fig. 13 [1]) until water drops out through the
purge valve outlet.
▶ Close the valve after a few moments, once the water flow is
smooth without air bubbling.
▶ Connect the appliance to the power supply via fixed wiring
installation, including earth conductor (section 4.5).
▶ Rotate circulation pump speed selector to position „III"
(Fig. 12)
Fig. 12 Circulation pump
▶ Activate „Purg" function ( page 33, section 5.7.6).
