The installation of hooks in the wall shall prevent the spontaneous movement of the EWH brackets
over them. For the purposes of EWH maintenance, the distance from the protective cover to the
nearest surface in the direction of the removable flange axis shall be at least 0.5 meters.
In order to avoid causing harm to the property of the customer and (or) third parties in case of faulty hot
water supply system, it is necessary to install the EWH in premises that are equipped with
waterproofing floors and drainage to the sewage system, and under no circumstances should you
place non-waterproof items exposed to water under the EWH. When placing the EWH in unprotected
premises, it is necessary to install a protective tray (not included in the EWH supply package) under
the EWH equipped with drainage into the sewage system.
In case EWH is installed in places that are difficult to access with a view to perform technical and
warranty maintenance (mezzanines, alcoves, ceiling void, etc.), the EWH shall be installed and
dismantled by the customer independently or at his/her own expense.
Connection to the water supply system
It is necessary to supply cold water to the EWH using a pre-treatment filter with a
purification degree of at least 200μm.
Install the relief valve (16) shown in Fig. 1, 2 at the cold water inlet (20) – the pipe with a blue ring, for
3,5 – 4 turns and ensure the connection tightness with any sealing material (flax, thread-fill tape, etc.).
When the water heater is operating, water can leak from the relief valve outlet pipe to relieve
excessive pressure, which occurs for the purpose of ensuring the water heater safety. The discharge
pipe shall remain open to the atmosphere and be directed downward constantly. It is advisable to
attach a rubber or silicone tube of the appropriate diameter to the drainage hole with a view to drain
water. It is necessary to drain a small amount of water regularly (at least once a month) through the
relief valve discharge pipe into the sewage system to remove calcareous sediments and to check
valve efficiency.
The handle (17) is designed to open the valve (18). Make sure that during the operation of the water
heater this handle is in the position preventing water from being drained from the tank.
The connection to the plumbing system shall be made in accordance with (Fig.1, 2) using
copper/plastic pipes or special flexible plumbing designed for a temperature of at least 100°C at the
maximum operation pressure. It shall be forbidden to use flexible connectors used in the past.
Plumbing and locking accessories shall be in line with the parameters of the water supply network and
have the necessary quality certificates. During installation, do not use excessive force to avoid
damage to the pipe threads, as well as the glass and porcelain finish of the inner tank.
CAUTION! It shall be forbidden to use the EWH without a relief valve or use a valve
made by other manufacturers.
After connecting the EWH, make sure that the cold water shutoff valve in the EWH (23) is open and
the hot water shutoff valve (24) is closed. Open the cold water inlet faucet in the EWH (21), the hot
water outlet faucet from the EWH (22) and the hot water faucet on the mixer to allow air to flow out of
the EWH. When the EWH has been filled in full, water will flow from the mixer faucet in the form of a
continuous stream. Close the hot water faucet on the mixer, check the flange for leaks and, if
necessary, tighten the bolts.
