ATTENTION! The installation and set-up of the water heater must be carried out by a
qualified technician in conformity with the applicable rules and hygiene and sanitary standards
in force and with any provisions set forth in this manual.
6.1. Hot-water boiler bonding against the wall
6.1.1. Prepared fastening must support a weight that is three times higher than the weight of the
water heater filled with water.
6.1.2. The appliance should be installed as close as possible to the point of water intake to limit heat
dispersion.
6.1.3. Allow for a clearance of at least 50 cm under the appliance and a clearance of 10 cm from the
ceiling for maintenance.
6.1.4. Fastening of hooks to the wall must prevent inadvertent movement of the bracket of the water
heater over them. After installation, be sure to check security of the fastening.
6.1.5. To prevent the property of the customer and (or) third party from damage caused by failures
of hot water supply system, it is recommended to mount the water heater in the premises provided
with waterproof floor and sewer drain. Never put objects sensitive to water under the water heater.
6.1.6. During mounting water heater in the unprotected areas, you must install underneath the
protective tray with drainage into the sewer.
6.2. Hydraulic connection
6.2.1. Safety valve supplied must be installed on the cold water inlet of the water heater (marked
with the blue ring). It is recommended to turn the safety valve no more than 3-4 turns, providing
sealing with water-proof sealing material.
6.2.2. Connect the inlet of the safety valve to the cold water line with a tube or flexible hose.
6.2.3. Connect a tube or flexible hose to the hot water outlet of the water heater (marked with the
red ring) for hot water removal to the draw-off point.
6.2.4. For easy maintenance, it is recommended to install a T-piece with shut-off valve between the
cold water inlet and safety valve of the water heater. It will help to drain water from the water heater
without safety valve removal.
6.2.5. To facilitate the access of air into the tank when draining water, it is recommended to install
an additional T-piece with shut-off valve at the hot water output.
6.2.6. When water pressure exceeds 5 bar, place before the safety valve a reducer to reduce the
pressure.
6.2.7. The device cannot work with water where hardness is less than
above 30 °F, it is necessary to use water softener to reduce the formation of scale and probability of failure
of the heating element.
6.2.8. Connection to open tank filled with water (Fig. 2). Water is supplied to the water heater from
the tank by gravity. Safety valve is not necessary in this type of connection.
Attention! During installation and operation of the water heater it is FORBIDDEN
use previously used fittings and should only be used new plumbing wiring.
Installation of safety valve included in the delivery set is necessary. Do not install any
