Before filling and putting the Proterm Skat electric boiler into operation, you must perform the following steps:

Loosen the cap air valve pump

Loosen and unscrew the rotor shaft cap and use a flathead screwdriver to rotate the shaft.

If quite noticeable resistance is felt when the shaft rotates, it is necessary to dismantle the motor part of the pump.

After this, clean the entire stator or pump rotor of impurities.

Before removal Wilo pump It is necessary to ensure that the following conditions have been met:

The water temperature in the boiler unit has reached a safe value (40°C).

The boiler was switched off via the main switch.

The heating water inlets and outlets were closed.

The remaining water in the boiler was drained.

Wilo pump dismantling work:

Disconnect the connecting cable connecting the pump to the control board.

Remove the heating water pipe leading from the pump to the heat exchanger.

Disconnect the tube leading to the expansion tank.

Pull out the safety clip.

Loosen and unscrew the pump safety screws located at the bottom of the boiler.

After turning the pump slightly clockwise, remove it.

Safety valve

If the maximum permissible pressure value in the Proterm Skat boiler is exceeded, excess water will be drained through a safety valve. The valve response pressure is 3 bar. The outlet of the safety valve must be equipped with a suitable drain.

If it is necessary to remove the safety valve, do the following:

Wait until the water has cooled to around 40°C.

Disconnect the Skat Protherm boiler from electrical network.

Close all valves located under the boiler installation.

Disconnect the drain pipe from the safety valve.

Release the water from the boiler system using the drain valve.

Remove the safety valve retaining clip.

Heating water temperature sensors

Temperature sensors - If replacement is necessary, remove the sensor together with the retainer and pull out both two connectors.

Emergency thermostat - 100 °C causes the boiler to stop working - error code F20 (unlock manually). The emergency thermostat of the heating circuit is located at the water outlet of the boiler heat exchanger.

To replace it, unscrew the screws located on the thermostat holder, remove the thermostat along with the holder and disconnect both connectors.

Pressure sensor

The pressure sensor is used to determine the water pressure in the boiler (heating system). If there is a lack of heating agent in the boiler, the pressure sensor will transmit information to the control board, which will give a command to stop it.

As the water pressure increases, the volume of the membrane carrying the magnet will increase. Opposite the magnet there is a Gall sensor, which changes the incoming voltage on the Proterm Skat boiler control board depending on changes in parameters magnetic field. The change in the magnetic field parameters depends on the change in the distance of the Gall sensor relative to the position of the magnet.

Before removing the pressure sensor, it is necessary to close the heating water supply and then drain the water from the unit using the drain valve. Pull slightly to remove the pressure sensor connector. Using a flathead screwdriver, remove the pressure sensor safety clamp. Remove the pressure sensor by pulling it towards you.

Dismantling the heating water circuit heat exchanger

Heat exchanger dismantling work:

Remove the front cover, side panels and top cover of the boiler unit.

Disconnect the heating element wires from the Skat Protherm electric boiler control board and the terminal box and disconnect the grounding conductor.

Disconnect the heating water supply pipe at the bottom of the heat exchanger.

Remove the heating water drain pipe at the top of the heat exchanger.

Loosen and then remove the bolts located at the top.

Pull up slightly to remove the heat exchanger from the boiler.

Removing the heating coils

Dismantling operations:

Remove the front panel of the boiler and its top or bottom cover (depending on which element needs to be replaced).

Disconnect the appropriate heating element wires from the control board and terminal block, as well as the grounding conductor.

Using a wrench of appropriate size, unscrew the heating element from the heat exchanger body in a counterclockwise direction.

Expansion tank

The expansion tank serves to equalize the pressure of heating water, the volume of which increases when heated. The expansion tank of the Proterm Skat electric boiler is designed for a maximum amount of water in the heating system - 90 liters (at a temperature of 75 °C). The expansion tank is located at the rear of the unit.

Before filling the heating system with water, check the pressure in the expansion tank. The initial pressure in it should be 0.2 bar greater than the static height of the water column in the heating system.

Fill the heating system with water. The filling pressure should be 0.2 - 0.3 bar higher than the water pressure in the expansion tank. The water pressure when filling the system is checked using a pressure gauge on the water supply side, in a cold state and after removing air from the system.

The valve for filling the expansion tank is located in its upper part. If water flows out of the expansion tank fill valve, this means that its membrane is damaged. In this case expansion tank needs to be replaced.

Work on removing the expansion tank:

Loosen and unscrew the screws located on the top of the boiler frame.

Loosen and unscrew the nut of the inlet pipe leading to the expansion tank.

Pull upward to remove the expansion tank.

When reinstalling, new gaskets must be provided.

Skat Protherm electric boilers do not have their own bypass, so it is recommended to install it directly in heating systems.

The boiler connection terminals must not be subject to loads from the heating system pipes. To do this, it is necessary to accurately observe the dimensions of the ends of all connected pipes, both in terms of height and relative to the distances from the wall and relative position individual inputs and outputs in relation to each other.

It is recommended to connect the electric boiler to the heating system in such a way that, if it is necessary to repair the boiler, heating water can only be discharged from it. During reconstruction, unfavorable layout, etc. The boiler can be connected to the heating system using flexible hoses intended exclusively for this purpose.

Used flexible hoses should be as short as possible, protected from mechanical and chemical influences, as well as from damage. The flexible hoses used must be replaced before the end of their service life or when they lose their ability to reliably perform their functions.
new.

The Proterm Skat electric boiler can be used to heat water entering the underfloor heating system. In this case, it is necessary to connect an emergency thermostat designed for underfloor heating systems to the boiler (not included in the delivery package).

Emergency thermostat for regulating water temperature in systems underfloor heating connects to the boiler power supply terminal block. Typically, boiler systems are equipped with a factory-installed jumper that short-circuits the terminals for connecting an emergency thermostat for underfloor heating systems. The jumper must be removed before connecting the thermostat.

The heating system, according to the readings of the boiler devices, must be filled with water at least until it reaches a hydraulic pressure of 1 bar (which corresponds to the hydrostatic height of a 10-meter water column).

If a room thermostat is installed in a reference room, it is necessary that at least one of the heating batteries located there does not have a thermostatic valve installed.

To increase thermal comfort in the room in which the room thermostat is located, we recommend not installing thermostatic heads on the heating radiators at all.

Before installing a new Skat Protherm boiler, the heating system must be thoroughly cleaned. It is recommended to install a sump tank in front of the boiler, namely on the return heating water pipeline. The septic tank must be constructed in such a way that it can be cleaned regularly without
need to drain large quantity heating water.

A settling tank can be combined with a filter, but a filter and sieve alone is not sufficient protection. Both the filter and the settling tank need to be checked and cleaned regularly.

Installation work for the electric boiler Proterm Skat:

Hung on a rail mechanical design boiler unit with pump and accessories.

The covering can be removed and secured to the rear wall with screws.

To install the boiler, it is necessary to choose a place that will allow service operations to be carried out without major obstacles.

If the boiler is installed in open system, the water level of the heating system should create a pressure of 1 bar.

IN heating systems equipped with thermostatic valves, the water circulation can be completely closed, in which case it is necessary to install a bypass pipe that is not equipped with a thermostatic valve or use a bypass.

When installing the front panel, make sure that the plastic frame sits exactly in place and that there is a grounding pad under each screw that secures the front panel.

Electrical connection of the Proterm Skat boiler

Skat Protherm electric boilers are designed for permanent connection to fixed electrical wiring. It is necessary to install a disconnecting device in it - main switch, the distance between open contacts is at least 3 mm for all poles, provided the commissioning instructions are followed.

Before installing the boiler, the user is required to ensure the installation of separate power wiring, including the main switch of the heating system, fuses, and also carry out other necessary changes in the internal electrical wiring.

In cases where it is not possible to connect to a three-phase electrical network, Proterm Skat boilers of the 6 and 9 kW power series can be connected to a single-phase one. To do this, you need to use the connecting bridge included in the boiler delivery package.

Using a connecting bridge, the contacts of the phase wires are mutually connected on the terminal block, designed to supply power voltage to the unit.

The fairly popular Protherm brand has long taken a strong position as a reliable manufacturer of heating equipment in Russia. In the entire range of electric boilers, there is one series - Proterm Skat. Protherm electric boilers are produced in 8 modifications with a power from 6 to 28 kW with the ability to continuously regulate power. Designed for use in closed systems heating with forced circulation of coolant. Boilers are installed on the wall, and all connections are made at the bottom of the boiler. Coefficient useful action equal to 99.5%, which is very high rate, even among electric boilers. The entire series of Skat boilers are single-circuit, and hot water supply is supplied by installing a boiler indirect heating.

Most of these disadvantages and advantages are inherent in most boilers operating on electricity.

Pros of Protherm Skat boilers

• High efficiency
• Easy to install
• Unpretentious in maintenance
• Eco-friendly
• Doesn't require much space
• Silent operation

Disadvantages of Skat series boilers

• High cost of electricity
• Dependence on power outages

Sometimes electric boilers are credited with shortcomings that are no longer relevant or were obviously incorrect; let’s look at some of them:

The boiler power is not enough to heat a house larger than 300 m2

This statement is incorrect, due to the fact that Skat boilers can be connected in a cascade to increase the heated area, if there is a shortage of 28 kW.

Frequent replacement of the heating element

Due to the fact that the heating medium is heated using a heating element, many believe that such a heating element will not last long, but you need to take into account the quality of the heating element itself and do not forget that it is not water that circulates in the system, but a coolant.

Installation of Proterm Skat boilers in a cascade

If a 28 kW boiler is not enough to heat the house, it is possible to install the Slopes in a cascade to increase the coverage of the heating area.
When two boilers are connected in a cascade, the second boiler is controlled using a room thermostat, which is connected to the first boiler.
This diagram will look like this:

The contacts of the room thermostat are connected to terminals 1 and 2 located on connector K8 of the main boiler, and terminals 9 and 10 of the main boiler are connected to terminals 1 and 2 of the slave boiler.

Only the Proterm Skat 28 kW and Proterm Skat 24 kW boilers can operate in cascade mode.
