Gorenje gv 150 [11/36] Connection to water supply network

CONNECTION TO WATER SUPPLY NETWORK

Connect the hot water tank to the water supply network according to the markings on the

pipes:

Blue – cold water inlet (HV) and red – hot water outlet (TV).

Connect the heating source according to the markings on the heat exchanger connections

on the rear of the hot water tank: red – medium inlet (VM) and blue – medium outlet (IM).

Between both connections of the heat exchanger you can additionally connect the circulation

pipeline (CV).

For safety reasons, a safety valve should be mounted on the inlet pipe, in order to prevent

pressure rise for more than 0,1 MPa above the rated pressure. The outlet nozzle on the

safety valve should have an outlet to the atmospheric pressure. In order to provide correct

operation of the relief valve, periodical inspections of the relief valve shall be carried out by

the user. When checking, simply open the lever, or undo the valve nut (depending on the

type of valve) and open the outlet on the safety valve. Water should be discharged from the

outlet nozzle, which proves that the valve operates perfectly. When heating the water in the

hot water tank, the water pressure in the tank will rise until the value set in the safety valve

is reached. Since ooding is prevented, water may drip from the outlet opening of the safety

valve. To catch the dripping water, mount a drip catcher under the safety valve. The outlet

hose, which is under the safety valve outlet, should be mounted directly downwards, in a

non-freezing environment.

Legend:

1 – Return safety valve

2 – Test valve

3 – Non-return valve

4 – Pressure reduction valve

5 – Stop valve

6 – Test piece

7 – Funnel with outlet connection

8 – Outlet valve

HV – Cold water inlet

IM – Medium outlet PT

CV – Circulation pipeline

VM – Medium inlet PT

TV – Hot water outlet

Hot water tank may be connected to the indoor plumbing system, without using the safety

valve if the network pressure is lower than 0,6 MPa.

If not, a pressure reduction valve should be mounted in order to assure that the pressure on

the hot water tank inlet does not exceed the rated pressure.
