Connection To The Water Supply - Gorenje Tiki TC 200-300/B Instrucciones De Uso

CONNECTION TO THE WATER SUPPLY

Connection to water supply shall be made according to the markings for the connections, as defined in previous
chapter.
For safety reasons the supply pipe must be .tted with a return safety valve that prevents the pressure in the tank
from exceeding nominal pressure by more than 0.1 MPa. The heating of water in the heater causes the pressure
in the tank to increase to the level set by the safety valve. As the water cannot return to the water supply system,
this can result in dripping from the out.ow of the safety valve. The drip can be piped into the drain by installing a
catching unit just below the safety valve. The drainpipe fitted under the safety valve out.ow must be piped down
in a straight vertical line and located in an environment free from the onset of freezing conditions.
In case the existing plumbing does not enable you to pipe the dripping water from the return safety valve into
the drain, you can avoid the dripping by installing expansion tank on the inlet water pipe of the boiler. Volume of
expansion vessel represents about 3 % of water tank volume.
The water heater may be connected to the household water supply system without a pressure-reducing valve
provided the supply mains pressure is less than 0.5 MPa. In case of the mains pressure exceeding 0.5 MPa, a
pressure-reducing valve must be installed to ensure that the pressure on the supply side of the heater does not
rise above the nominal value.

H - Cold water
T - Hot water
WARNING: The heating pump should not be in operation without water in the hot water tank, because of danger
of destruction of the compressor.
INSTALLATION OF THE HOT WATER TANK AND HEATING PUMP
Hot water tank with heating pump should be installed in a dry room with temperature of 7 to 35°C and minimum
volume of 20 m , protected from the onset of freezing, if possible close to other heating sources. In general,
3
we recommend installation in a large and well ventilated room with ambient temperature between 20 and 25°C
- these are optimum conditions for operation of the heating pump. When selecting the installation place, avoid
dusty places, as dust deposit may impair the operating characteristics.
