When choosing the place of installation total weight of EWH filled with water shall be taken into
account. Walls and floor with low carrying capacity should be strengthened accordingly. When drilling
(making) holes in the wall, regard is to be had to cables, ducts and pipes in the wall. EWH is
suspended with casing on anchor hooks fixed in the wall.
Hooks mounting on the wall shall exclude spontaneous movement of EWH brackets along them. To
perform maintenance and servicing of EWH the distance from the protective cover to the nearest
surface in the direction of removable flange axis shall be at least 0,5 m.
In order to avoid damage of the user's and/or third parties' property in the event of a faulty hot water
system, it is required to install EWH in spaces with waterproofing and drainage to the sewers, and in
no case to place under items exposed to the water under EWH. When placed in unprotected areas a
protective plate (not supplied) with drainage into sewers shall be installed under the EWH.
In case of placing EWH in hard-to-reach places in order to perform maintenance and warranty
service (mezzanine floors, niches, ceiling voids, etc.), installation and dismantling of EWH is carried
out by the user on his own or for his own account.
Connection to water supply
Cold water shall be supplied to EWH using pre-filter with water treatment level not less
than 200 µm.
Install pressure relief valve (17) at the cold water inlet (21) tube with the blue ring, with 3,5 – 4
revolution, ensuring junction tightness with any sealing material (flax, FUM tape, etc.).
During water heater operation water may leak out of the exhaust outlet pipe of the safety valve to
relieve excessive pressure, which is made for the purpose of water heater safety. This outlet pipe shall
remain open to the atmosphere and be installed constantly down and in a non-freezing environment.
It is recommended to attach to the drain hole a rubber or silicone tubing of appropriate diameter to
drain moisture. It is required regularly (at least once a month) to discharge a small amount of water
through the exhaust pipe of the safety valve into the drain to remove lime deposits and to test the
operating functionality of the valve.
Knob (18) is intended to open the valve (17). It is required to control when operating water heater this
knob to be in position closing water draining from the tank.
Connection to water supply system shall be made in accordance with (Figure 1) using copper, plastic
pipes or special sanitary flexible conduits designed for temperature up to 100° C at the maximum
working pressure. Do not use used flexible pipes. Plumbing pipes and fittings shall conform to the
parameters of the water supply network and have the required quality certificates. Excessive efforts
are not allowed when mounting in order to avoid damage to pipe threads, glass-porcelain coating of
inner tank.
ATTENTION! Do not operate EWH without safety valve or valves made by other
manufacturers.
After having connected EWH make sure that cold water shut-off valve in EWH (24) is open and hot
water shut-off valve in EWH (25) is closed. Open the EWH cold water inlet valve (22), hot water inlet
valve (23) and hot water mixer faucet to allow outflow of air from EWH. When complete filling of EWH,
