When drilling (making) holes in the wall, regard is to be had to cables,
ducts and pipes in the wall. 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.
All models H_0 (pro), H_U (pro) are supplied with EWH mounting kit. The kit consists ofa
specialbracketand anchors.Thebracketshall be secured to thewallusinganchors andthen
installEWHthereon.
To perform maintenance and servicing of EWH the distance from the protective cover to
the nearest surfaceinthedirectionofremovableflangeaxisshallbeatleast0.5m.
In orderto avoid damage oftheuser's and/or third parties' propertyin the eventof 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
drainageintosewersshallbeinstalled under theEWH.
In case of placing EWH in hard-to-reach places in order to perform maintenance and

CONNECTION TO WATER SUPPLY
Cold water shall be supplied to EWH using standard domestic water filter (for
example, mud trapandbowlfilter).
Install pressure relief valve at the cold water inlet tube with the blue ring, with 3.5-4
revolution, ensuring junction tightness with any sealing material (flax, FUM tape, etc.).
Connection to water supply system shall be made in accordance with Figure 2 for model
H_U (pro) (pipes up) and in accordance with Figure 1 - for models H_0 (pro) using copper,
plastic pipes or special flexible sanitary-engineering piping. Do not use used flexible pipes.
When mounting excessive efforts are not allowed to avoid damage to EWH pipes, bioglass

After having connected open the EWH cold water inlet valve and hot water faucet
mixer. When complete filling of EWH, water will constantly flow from tap faucet. Close the
hot water tap on faucet mixer.
When connecting EWH in places not provided with water mains it is allowed to supply
water to EWH from auxiliary tankusingpumping station, orfrom the tank placedat aheightof
notlessthan5meters fromthetopofEWH.
Note: for ease of maintenance during EWH operation it is recommended to install drain
valve(4)(not inthescopeofEWHsupply)inaccordancewiththedrawing.Ifwaterpressurein
the main exceeds 0.8 MPa, at the inlet before the safety valve it is required to install relevant
reducingvalve(notinthescope of EWH supply).
