should be connected to the appliance by means of dielectric separators.
•
Plastic pipes (PP) are permeable to oxygen. It is forbidden to connect the heat exchanger to system
made by PP pipes as well as to open circulation system! Abusing this rule will lead to corrosion inside tube.
•
It is obligatory for the system installer to fit an 8-bar safety valve No5 on the cold water intake pipe
(Fig. 8).
•
It is forbidden a presence of any stop valves, taps between the safety valve and storage tank!
The safety equipment for protection against over pressure must be operated regularly in order to remove
limescale deposits and to check that it is not blocked (Fig. 8)
The drain pipe No6, connected to the safety valve must be installed sloping continuously downwards
and, in a place, where it is protected against the formation of ice (Fig. 8). Using a tundish is obligatory
(Fig.8a)
A
n expansion vessel No10 (Fig.8) should be installed in order to absorb water expansion due to tempera
-
ture variation. Pressure regulator No3 and expansion vessel should be calculated together by qualified
person.
WARNING! The heat pump for the production of domestic hot water is capable of heating water up to
more than 65°C. For this reason, as a protection against burns, it is necessary to install an automatic
thermostat mixing equipment No16 to the hot waterpipe (Fig. 8)
C
ondensate, that forms during the operation of the heat pump, flows through an appropriate discharge pipe (G 3/4”) that passes in
-
side cladding and it comes out on the side of the equipment. Use flexible hose Ø16 (69, fig. 9) to connect it to the plastic nipple 68.
This plastic part 68, should be handle with care in order to avoid damages. Connected the hose to a siphon so that the condensate
can flow freely (Fig. 9).
The plastic nipple No68 (fig.9) should be manipulated gently, by hand, to avoid damages!
The device is supplied already wired for the main power supply. It is powered through a flexible cable and a socket/plug combina
-
tion (Fig. 10 and Fig. 10a). An earthed Schuko socket with separate protection is needed for the connection to the mains power
supply.
WARNING! The power supply to which the equipment will be connected must be protected by an ade-
quate residual current circuit breaker at least: 16A/230V
The type of residual current circuit breaker must be chosen by evaluating the type of electric equipment
to be used on the entire system.
With reference to the connection to the main power supply and the safety equipment (e.g. residual cur-
rent circuit breaker) comply with standard IEC 60364-4-41.
WARNING! Check that the equipment is connected to the earth cable.
WARNING! Check that the line voltage corresponds to that indicated on the equipment identification
plate.
WARNING! Do not exceed the maximum permitted pressure indicated in the “general technical data”
section; 8 Bar
WARNING! Check that the water circuit safety valve is working;
The commissioning procedure must be carried out by performing the following procedures:
Fill the boiler by opening inlet tap No2 (Fig. 8) and the tap hot water of your bathroom. The tank is fully filled with water, when only
water without air starts leaking trough the tap in the bathroom. Check that there are no leaks from gaskets and connections. Tighten
the bolts or connections where necessary;
