Depending on the condition of the power supply, unstable power or voltage may cause malfunction of the parts or
control system. (At the ship or places using power supply from the electric generator, etc.).
HEATING SYSTEM FILLING
Set the pressure of the heating circuit in the expansion vessel to 1.5 bar. Usually, the replenishment of the heating
circuit is stationary and pre-connected to the water inlet, in which case the replenishment takes place individually according
to the system. If the filler in the heating circuit is not water, then the system is filled with the appropriate liquid. As an
additional protection against freezing, in some cases the water in the heating system may be mixed with glycol, however,
this concentration should not exceed 15%. In this case, the efficiency of the heat pump decreases.
HEATING SYSTEM FILTER AND VALVES
The heat pump does not include a filter and a safety valve. These components must be installed on the pre-prepared
heating system return line. The safety valve shall be installed vertically.
Do not leave the safety valve closed.
INTERNAL CIRCUIT CIRCULATION PUMP
The internal circuit pump is included in the heat pump set and is installed in the device at the factory. The circulation pump
is controlled by the central processor while maintaining optimal flow. The control system monitors the operation of the
circulation pumps, and a warning is received in the event of a deviation.
THE HEATING SYSTEM RISING AND FILLING
The heat pump is an integral part of the heating system. Heat pump failures are usually caused by poor water quality in the
heating system, or by the presence of air in the system. The presence of air in the system produces corrosive products
such as magnetite or sediment. Magnetite has an abrasive effect that is especially enhanced in pumps, valves, or eddy-
flow components, such as a condenser. Before installing a heat pump in a heating system that needs to be filled or uses
water that is not pure, auxiliary measures such as the installation of filters and automatic outlets must be taken. Filling with
untreated drinking water will inevitably result in the formation of sediment. Effect: formation of limescale deposits on the
heat transfer surfaces. Decreased efficiency and energy consumption increases. 1 millimeter of lime deposits causes an
energy loss of 10%. In extreme cases, this can even damage the heat exchangers.
Do not use water treatment additives in the heating system. Additives can be used to adjust the pH of the water; the
recommended pH of the water is 7.5-9. The safest and most efficient operation of the system is achieved by using low-salt
water.
When combining a heat pump with a boiler, it may be necessary to fill the system with desalinated water to protect the
boiler from corrosion. This reduces electrical conductivity and the risk of corrosion.
THERMAL INSULATION
All heat and cold conductive parts of the piping must be insulated with special means of thermal insulation in accordance
with current standards. The main normative document, which defines the requirements for thermal insulation, is Order No
1-245 of the Minister of Energy of t
he Republic of Lithuania “ON THE APPROVAL OF RULES FOR INSTALLATION OF
THERMAL INSULATION OF EQUIPMENT AND HEAT TRANSMISSION NETWORKS” of 20 September 2017.
