Frequently Asked Questions - SWVPC-250 KOSPEL

Can the SWVPC-250 be installed horizontally?

No, the cylinder is designed for vertical installation only on its screw-on feet.

What is the maximum water pressure allowed?

The maximum water pressure is 0.6 MPa. If supply pressure exceeds that, install a pressure reducing valve before the cylinder.

How often should I check the safety valve?

Check the safety valve every 14 days by operating it briefly. If water does not flow, the valve may be faulty and should be replaced.

How often should the magnesium anode be replaced?

The magnesium anode should be inspected annually and replaced every 18 months to ensure corrosion protection.

Can I use the buffer tank for domestic hot water?

No, the buffer tank is intended only for heating water or cold storage in central heating systems. It cannot supply domestic hot water.

What immersion heaters are compatible?

Compatible immersion heaters include GRW 1.4 and GRW 2.0, with a maximum length of 430 mm. Fit them in place of the cork (1 1/2").

Why is there water dripping from the safety valve outlet?

A small amount of water dripping from the safety valve outlet is normal during operation. Do not block the outlet.

How do I clean the cylinder interior?

Periodic cleaning should be done by a qualified professional. Frequency depends on water hardness. For sediment removal, contact service.

What should I do if I notice a water leak?

Immediately close the cold water supply valve and the CH system valves, then contact the service department.

Is it necessary to insulate the pipes?

Yes, insulating the outlet pipe and heating coil connection pipes is recommended to minimise heat loss and improve efficiency.

2. The manufacturer of this cylinder will not be liable for any damages due to the failure to follow the installation and operation instructions.
3. During all work related to the installation, servicing or maintenance of the device, the principles of health and safety, explosion protection, fire protection and environmental protection must be observed in accordance with the applicable requirements and regulations in the respective country.
4. The cylinder must not be installed in rooms where the temperature may drop below 0^ C.
5. The cylinder installation and the initial start-up, as well as all electrical and hydraulic work must be performed by a qualified professional installer.
6. The cylinder is designed for vertical installation only (screw on feet).
7. The device must be installed in such a place and in such a way in order not to flood the room in case of the emergency water leak.
8. Connections to water supply system, central heating system, and solar collectors must be made in accordance with the diagram in this installation instruction. Failure to follow the installation instruction invalidate the warranty and may cause cylinder's damage.
9. A connection to water supply system must be made in accordance with legally binding norms.
10. The cylinder is a pressure appliance designed for connection to the water supply system where the water pressure doesn't exceed 0,6 MPa. If the water pressure exceeds 0,6 MPa, the pressure reducing valve before cylinder must be fitted.
11. A small leak from the safety valve through the outlet pipe may occur- it's a normal operating state of the appliance. The outlet pipe has to remain open. Do not clog it, as a clogged outlet may lead to the breakdown of the cylinder.
12. Do not use the cylinder if you suspect that the safety valve may be faulty.
13. The tank is equipped with magnesium anode- an additional protection against corrosion. The anode is an operating part, therefore, it is exposed to wear. The condition of the magnesium anode should be controlled every 12 months. The anode must be replaced once every 18 months.
14. The heating water must comply with all of the relevant local water quality standard.
15. Rated temperature of water in the cylinder should not exceed 95^ C.
    The cylinder is suitable for fitting an immersion heater with thermostat e.g. GRW 1.4, GRW 2.0. The immersion heater must be fitted in lieu of cork 1 12 .
    A maximum length of immersion heater is 430mm.

Cylinder SWVPC is a device with double tank intended to heating medium system with heat pump.

The upper tank is enamelled with double heating coil, intended to prepare domestic hot water. In the lower part, there is a buffer with unenamelled tank, anti-corrosion inhibitor protected for transport.

Buffer tank is intended for heating water and/or cold storage with co-opeartion with central heating boilers and heat pumps. Additionally, buffer tanks may also perform the following function: divider (hydraulic clutch), hydraulic separator, heating circuit from the boiler room. Can't work with domestic hot water.

Connection to the central heating system

Cylinder must be fitted to the central heating system by pipe unions 1¼". A cut-off valves must be installed before the pipe unions. A flow rate of heating water must be high enough to maximise cylinder efficiency (see ,Technical data table). It concerns the forced circulation installation (with a central heating water pump).

Model SWVPC is equipped in double heating coil.

Please follow water connection instructions below:

- install the T-connection with 6 bar* safety valve and the drain valve to the fitting of cold water inlet [ZW]. It's forbidden to install a cut-off valve (or any flow reducer) between the tank and the safety valve and on its outlet. The safety valve must be installed in such a place as to quickly let you notice the outgoing water,

- install the cylinder equipped with the safety valve to the water system,

- install the cut-off valve on cold water supply pipe.

Hot water outlet should be led to the connections in the upper part of the cylinder. Every cylinder is equipped with connection intended for its installation to the DHW circulation. The buffer tank can be assembled in the heating system:

• open system according to the current standards,
• closed system according to the current standards.

*Please note: use the safety valve matched to the heat's source. Installing a safety valve with inadequate capacity can result for excessive pressure increase in the cylinder and as a result a leakage. In this case, warranty does not cover damage caused.

Before the start-up make sure that the installation procedures have been carried out in accordance with the regulations included in this manual.

Cylinder must be filled with water:

• turn on the valve on cold water supply pipe,
• turn on the hot water outlet valve (water outflow without the air bubbles indicates that the tank is full),
• turn off the outlet valves.

Turn on the valves connecting cylinder with the central heating system and fill the surface area of buffer. To vent the buffer, you should use air vent on supply. Air vent is also recommended at the highest point of the coil supply connection. Check for water and heating medium leaks. Check out the safety valve performance in accordance with valve manufacturer's instruction.

Tank emptying

In order to empty the tank:

• turn off the valves which connect the buffer tank with central heating system,
• turn off the valves which connect the buffer tank with PC circuit,
• turn off the valve to connect the cold water inlet with cylinder,
• turn off the valve on the cold water inlet,
• turn on the drain valve.

Follow the guidelines below for safety and trouble-free cylinder operation:

• Check out the safety valve performance once every 14 days. Do not use the cylinder if the water does not come out (it indicates that the valve is broken).
• Clean inside of the cylinder periodically. The frequency of cleaning depends on the degree of water hardness. The cleaning should be done by a qualified person.
• The wear condition of the anode must be inspected annually.
• The anode must be replaced once every 18 months.

- anode rod replacement [3]: take off upper lid [1], take out an insulation ring, turn off the cut-off valve on cold water supply pipe, turn on the hot water valve (mixer tap), turn the drain valve on, drain as much water as you need to easily unscrew the anode rod (avoiding room flooding). Remove the cork and unscrew the anode rod.

• Heat up the water above 70^ periodically for hygiene reasons.
• Failures or malfunctions notify to the seller.
• Insulate the outlet pipe and heating coil connection pipes to minimise the heat loss (recommended).

Above activities are beyond of the scope of warranty service (should be done by the user).
