Connection with water installation
Connection with water installation must be performed according to binding norms of
hydraulic installation. The cylinder is a pressure appliance designed for connection
with water installation where the water pressure doesn't exceed 0,6 MPa. If the water
pressure exceeds 0,6 MPa the pressure reducing valve before cylinder must be fitted.
Please follow the water connection instructions below:
- install the T-connection with 6 bar* safety valve and the drain valve to
the inlet fitting of cold water [ZW]. It's forbidden to install a cut-off valve
(or any flow reducer) between storage and the safety valve and on it's outlet.
The safety valve must be installed in that place to let you quickly see the outgoing
water,
- install the cylinder equipped with the safety valve with water installation,
- install the cut-off valve on cold water supply pipe.
Hot water outlet pipe must be connected to the fitting, which is located in the upper part
of the unit.
Each cylinder is equipped with fitting for domestic hot water circulation connection.
*Please note: use the safety valve matched to the heat's source. Installing a safety valve
with inadequate capacity can result for excessive pressure increase in the cylinder and
as a result a leakage. In this case, warranty does not cover damage caused.
