distances between the bolts (studs) for mounting the units. Vertical heaters
of 150 and 200 liters are equipped with special type of suspension plates
and correspondingly the distance between the bolts (studs) differs from that
of other models and modifications, please refer to Fig. 1.
WARNING! The bearing plates of horizontal water heaters must be
securely clamped to the premise wall. Under the bolts heads (nuts on
studs) must be placed support washers!
Given the greater weight for water heaters of 150 and 200 liters there are
higher requirements for fixing to the premise wall and to the wall itself:
Given the wall type, material and strength, in order to provide secure
џ
attachment for vertical water heaters it is necessary to build an
additional structure or to take adequate measures to strengthen an
existing one. Samples of such constructions are shown on Fig. 4 for
reinforced concrete wall thick 25 cm and more, and on Fig. 5 - for brick
wall and others materials.
The producer supplies additional package of bolts brackets for
џ
horizontal water heaters. These water heaters may be mounted only
on reinforced concrete wall thick 25 cm and more. The brackets are
attached to the premise wall with securely held studs (anchors) The
location of the brackets and the way the water heater is attached to
them are shown on Fig. 2.
WARNING! Non observance of the requirements for fixing the water
heater on the wall may cause damages of the appliance, damages on
other appliances and the premises, where the device is located, as well
as corrosion of the casing or even more serious failures and damages. In
such cases eventual failures and damages are not a subject to
manufacturer and seller warranty liabilities and will be at the expense of
the party which has not observed the present manual instructions.
The water heater mounting to the premise wall must be completed only by a
specialist.
WATER HEATER CONNECTION TO THE WATER
SUPPLY NETWORK
The plumbing to which the water heater will be connected, as well as any
other elements included in it shall have to withstand sustained water
temperatures above 80 °C and for short periods - above 100 °C, as well as
to pressure at least twice high the appliance working pressure.
Upon connection of the water heater to the water supply grid, the arrows and
indication rings around the water heater pipes for hot and cold water must be
observed (inlet and outlet pipes). With an arrow towards the pipe and blue
color is marked the cold water pipe and an arrow starting from the pipe in red
color – the hot water pipe. Some appliances pipes are additionally marked
with badges. The pipes outlets are with threading 1/2". A schematic diagram
for water heater connection is shown on Fig 6. Where local regulations
require use of additional devices that are not included with the unit supply
set and are not placed in the packaging, these must be purchased and
installed according to regulations.
The water heater is equipped with a combined check-safety valve. The latter
is located in the appliance packaging and MUST OBLIGATORY be mounted
on the cold water pipe. During that installation follow the arrow on its hull
showing the direction of water flow through it.
WARNING! It is FORBIDDEN to install any kind of shut-off fittings
between the combined valve and the water heater! It is absolutely
forbidden to obstruct the lateral opening of the combined valve and/or to
block its lever!
Where the plumbing pipes are copper or of another metal, other than that of
the water tank, or where brass fasteners are used, it is obligatory to install on
the water tank inlet and outlet non-metallic couplings (dielectric fittings).
ATTENTION! For appliances with heat exchangers. It is compulsory
that all additional tube outlets (except the outlets of the heat
exchangers), which will not be connected to the plumbing, as well as the
outlets for additional thermostats and/or thermomanometer must be
closed with the equipment from the package, or other suitable
equipment for this purpose. The compounds should be sealed for a
water pressure of at least 1,6 MPa.
It is recommended to set up a draining system for any dripping from the
combined valve side opening. The draining pipe must have a constant
downward slope and located in frost secure environment and its ends to be
constantly kept open to the atmosphere.
Once the water heater is connected to the water supply main, its water tank
should be filled up with water. It is carried out in the following order:
Open completely the turn-cock for hot water of the most distant mixing
џ
tap;
Open the stop valve on pos. 4 from Fig. 6);
џ
Wait until a thick and powerful stream of water runs out of the mixing
џ
tap;
Close the turn-cock for hot water of the mixing tap;
џ
Lift the lever of the combined valve on pos. 5 from Fig. 6) and wait for
џ
about 30-60 seconds until a thick and powerful stream of water runs
out from the valve side opening;
Loose the lever of the combined valve.
џ
WARNING! If no water is coming out of the opening of the combined
valve or the flow is weak (during normal water pressure), this should be
considered as a malfunction indicating that impurities from the plumbing
or caused by sewage connections have blocked the safety valve of the
combined valve.
IT IS FORBIDDEN to proceed with appliance electric connection before
eliminating the reason for malfunction!
WARNING! Failure to comply with the requirements for connection to
the water supply system may cause partial filling up of the water tank and
malfunction of the heating element, or when the combined valve is not
installed at all or has been improperly installed this may even cause
destruction of the water tank, the room and/or other damages to tangible
and intangible property. Such consequences are not within the scope of
manufacturer or seller warranty liabilities and shall be at the expense of
the party, which has not observed the present manual instructions.
WARNING! The combined reciprocating safety valve is one of the unit
safety components ensuring security for water heater users. It is
specifically FORBIDDEN to use the water heater with a defective or
removed/unmounted combined safety valve!
The water heater connection to the water supply system must be performed
only by qualified persons.
Where necessary the safety valve may serve for draining the water out of the
water tank. It is carried out the following order:
Disconnect the heater from the mains with the optional device and for
џ
greater security disconnect the fuse in the heater phase circuit.
The cold water access to the appliance is cut – close the stop cock
џ
(pos. 4 from Fig. 6).
Open the hot water cock on the tap or disconnect the tank hot water
џ
pipe (outlet pipe) connection.
Lift the lever of the combined valve on pos. 5 from Fig. 6 and wait until
џ
the water stops flowing out of the valve opening.
These steps do not still secure the complete draining of the water out of the
tank. It is completed only by a qualified person because it requires complete
disconnection of the appliance electric circuit and dismantling the water tank
flange.
WARNING! IT IS STRICTLY PROHIBITED to turn on the heater power
while the water tank is partially or completely emptied of water! Do not
forget to fill the tank with water before putting it back into operation.
WARNING! The coolant circulation through the heat exchanger of a
water heater equipped with such device is PROHIBITED when the water
tank is partially or completely emptied of water.
WARNING! When draining the water out of the water tank all necessary
precautions must be taken to prevent damages from flowing out water.
CONNECTING THE WATER HEATER WITH HEAT
EXCHANGER TO THE ALTERNATIVE HEAT
SOURCE CIRCUIT
The water heater with heat exchanger must be connected to the alternative
heat source in accordance with the special additional instructions provided
