When establishing pipeline connection, follow the installation order of the fittings

according to Figure 2 as the correct operation of the equipment depends on this. The

combined safety valve has to be connected to the cold water branch respecting the flow

direction marked by an arrow. The equipment has to be provided with a safety valve

controlled for maximum 0.7 MPa operating pressure.

[The safety valve has to be mounted directly in front of the storage tank, onto the

coldwater branch, in a frost-free environment. The safety valve is an accessory of the

equipment.

Before mounting the valve, the coldwater pipe has to be flushed thoroughly, in order to

avoid any damage caused by a possible pollution. The combined safety valve contains a

one-way valve therefore it is not necessary to mount in a separate one-way valve. During

heating, leakage of extending water has to appear on the outlet tube of the combined

safety valve. When mounting, check if leakage is visible.

If the water pressure in the system exceeds the value of 0.6 MPa even temporarily, a

pressure reducing valve has to be mounted in front of the hot water storage tank, in the

place as indicated in Figures 1.b and 2.b. If this is missing, at the above mentioned

pressure, the safety valve will be leaking outside heating as well. The pressure reducing

valve has to be purchased and mounted by the customer. A closing valve has to be

mounted in the coldwater pipe leading to the storage tank in front of the fittings

(combined safety valve, one-way valve, etc.). With the help of this, the hot water storage

tank and the water pipe fittings can be separated from the pipeline (in the case of failure

or other maintenance works).

OPERATION AND MAINTENANCE

If you observe water leakage or other abnormality from the inside of the storage tank,

immediately separate the equipment from the pipeline with the help of the closing valve.

IN THE CASE OF INDIRECT HEATING, PROTECTION AGAINST OVERHEATING HAS TO BE PROVIDED BY

THE INDIRECT HEATING EQUIPMENT.

Active anode

In addition to the enamel coating, the tank of the hot water storage tank is protected by an

anode as well against corrosion therefore it is important that the tank should always

contain an active anode of an appropriate size. Therefore the state of active anode has to

be revised every two years. This shall be a pre-condition of the guarantee for the tank (see

warranty certificate). If the anode diameter shrinks to about 10 mm, it has to be replaced.

It is extremely important that the active anode should be in a proper contact with the tank.

Therefore when a new anode is mounted or after other repair works, the link between the

active anode and the earthing screw has to be implemented in a way that provides a

contact of electrically proper conduction.]

Scale removal

Depending on the quality and quantity of the used water, scale deposition may occur on

the heat exchanger and the tank wall. The deposited scale decreases the efficiency of
