1. Operation and maintenance

The VULCAN water heater in its standing and suspended versions is a pressure device adapted for operation with a maximum water pressure of 0.6 MPa (6
bar). A water heater is a device designed to heat and store water in a heated state. It can be used in households, catering facilities, social rooms in industrial
facilities, etc. The water heater can be used with all types of heating boilers, in particular, suspended, single function boilers. The main part of the water
heater is a tank, which is made of sheet steel coated with vitreous enamel.

1.1. Device description

The water heater is equipped with a coil with a large heat exchanging surface, which enables rapid heating of large quantities of water. In the standing water
heater, all hydraulic connections are located in the upper end cap, while in the su spended water heater in the lower end cap. Hydraulic connections have an
external thread, which allows easy assembly and disassembly of the tank. The water heater can also be connected to a circulation system and a temperature
sensor. A standing water heater has, in its bottom end cap, a draining connection that allows the tank to be emptied. The water heater has additional
corrosion protection in the form of a magnesium anode, which uses the electrochemical potential difference between the material of the anode and that of
the tank. The magnesium anode is to be found in the top end cap for the standing version on a 5/4" plug and a M8 one for the suspended version. The water
heater is insulated with a layer of CFC free polyurethane foam to minimize heat loss. A suspended heater is suitable for hanging on a wall or other sufficiently
durable construction elements, but only in the vertical position. Both a standing and a suspended water heater can have a heating element connected.
Remember!
1. Do not turn on the water heater when empty.
2. Do not operate the water heater without a properly functioning safety valve (the safety valve should be checked every 14 days by turning the cap to the
right or left, so that water flows out of the side outlet. Then, turn the cap in the opposite direction until it clicks into the previous position and tighten
it to the valve body. If no flow of water occurs when the cap is turned, the valve is defective. When the cap is turned and there is a continuous leak of
water once the cap is returned to the previous position, the valve poppet has become polluted and the valve should be flushed repeatedly by opening
and closing the valve using the cap. Attention possibility of hot water outflow. The company is not responsible for safety valve malfunction caused by
incorrect installation of the valve and installation errors, such as the lack of a pressure release valve in the cold water outlet installation. The maximum
pressure for a full opening of the safety valve must not exceed 0.67 MPa.
3. Adequate protection of the boiler working together with the water heater ensures proper pro tection of the water heater coil.
4. The water heater must be flushed of sediment at least once a year.
5. The magnesium anode must be replaced every 18 months it is not covered by the warranty.
6. To extend the life of the water heater and ensure smooth operation of the safety valve, filters to eliminate pollution should be used.
7. If the water heaters work in a very aggressive environment (e.g. shed, etc.), a product spe cially prepared for working in such an environment must be
purchased (the manufacturer will prepare parts that are likely to suffer from accelerated corrosion by properly securing them chemically).
8. It is not allowed to prevent water from dripping from the safety valve – do not clog the safety valve outlet. If the safety valve is leaking water all
the time, the pressure in the water supply installation is too high or the safety valve is defective. The valve outlet should be pointing down. It is
recommended to place a funnel for draining water under the valve. A hose can also be attached to the water outlet for draining leaks caused by opening
of the safety valve. The hose should be resistant to a temperature of +80°C, have an internal diameter of 9 mm and a maximum length of 1.2 m, be led
from the outlet with a downward grade (min. 3%) in an environment where the tem perature does not drop below 0°C. The hose should be secured
against reduction in flow capacity (crushing, clogging) and its end should be visible (in order to check the functioning of the valve).
9. The water heater is protected against the possibility of excessive temperature of the heated water by means of an adjustable thermoregulator and
temperature limiter, which shuts off the electrici ty supply to the heating element, if the temperature of the water heater wall reaches 80°C.
10. "Galmet" reserves the right to make any modifications without prior notice to the clients.
2. Installation
INSTALLATION OF THE WATER HEATER should be done by a technician with appropriate qualifica tions. Installation is to be confirmed in the warranty card.
Due to the design of the water heater, it can be installed only VERTICALLY or in a SUSPENDED position, depending on the type of tank. The water heater must
be connected directly to the water supply network (with possibility of disconnec tion, e.g. for maintenance) with a pressure not exceeding 0.6 MPa and the
minimum pressure can not be lower than 0.1 MPa about l atm. If water pressure in the water supply network exceeds 0.6 MPa, it is necessary to reduce the
