2. Installation
The HEATER should be INSTALLED by an appropriately licensed installer. Installation must be confirmed in the warranty card. Due to its design, the heater
must be installed VERTICALLY only. The heater must be connected directly to the water main system (with the capability of disconnecting it, e.g. for
maintenance) of pressure not exceeding 0.6 MPa, whereas the minimal pressure must not be smaller than 0.1 MPa (approx. 1 at). In the case when the water
main system pressure exceeds 0,6 MPa, it is necessary to reduce the pressure with a pressure reducing valve. The relief valve, such as the ZB8 FACH Cieszyn,
must be installed on the cold water supply pipe, however relief valve equipped with the feature of reducing water pressure in the heater by redirecting it to
the supply system, the water supply system within 5 m from the relief valve should sustain water temperature of +90°C. The discharge port of the relief valve
must be opened to the atmosphere at all times. It is allowable to connect the heater in a manner providing several water outlet points. The heating coil of the
water exchanger can be supplied from a low temperature water boiler protected in accordance with PN-91/B-02413, operating in an open system, or from a
CH low temperature water boiler operating in a closed system (with a membrane expansion vessel) in accordance with PN-91/B-02414.
In order to protect the pumps, three-way valve and exchanger from dirt, a mesh-type filter shall be installed in the circuit. We recommend flushing of the
entire heating system prior to installation. All connected branching shall be thermally insulated. If the system operation assumes the usable warm water
heating priority using the three-way valve, we recommend following the installation instructions provided by the manufacturer of the three-way valve.
To shut down the heater for a short period of time, turn off the power plug from the wall socket.
cold water
In order to drain the tank it is necessary to:
1. Close the cold water inlet before the valve or the relief group.
2. Open the „ZS” drain valve.
3. Open the hot water faucet so the air could flow through to the tank.
3. Troubleshooting
MALFUNCTION
CAUSE
METHOD OF REMOVAL
The relief valve does not open
(also at the attempt of blowing-
through).
-
Relief valve is seized.
-
Clean or replace the valve.
Relief valve leaks.
-
The faying surface of the relief valve is
contaminated or damaged.
-
Water pressure is too high.
-
Clean or lap the faying surface of the relief valve.
-
Use a pressure regulator.
DHW water is dirty.
-
Plenty of deposit in the tank, or the magne-
sium anode is used up.
-
Clean the tank of any deposit, or replace the magnesium anode
(not covered by the warranty).
It is NECESSARY to use a dielectric connectors (made out of a plastic material - electrically nonconductive) between the hot and cold water
connections and the installation's connections in order to avoid iron-copper contact, also in case where the relief group is connected directly
to the tank. This extends the life of the water tank and prevents electrolysis phenomena, especially when the water is acidic (pH <7).
The symbol presented beside signifies that it is prohibited to dispose of worn electrical and electronic devices together with other waste.
These products should be delivered to assigned waste collection points for waste processing. A proper recycling of electrical and electronic
devices helps to protect the natural environment and prevents negative impact on human health.
