Frequently Asked Questions - SWVPC-60 KOSPEL

What is the difference between the two tanks of the SWVPC-60?

The upper tank (235 L) is enameled and intended for domestic hot water preparation. The lower tank (60 L) is a non-enameled buffer tank for storing central heating water and serves as a hydraulic separator.

What is the maximum pressure for the water supply?

The pressure must not exceed 0.6 MPa (6 bars). If the mains pressure is higher, install a pressure reducer before the tank.

How to install the safety valve?

Mount a safety valve with an opening pressure of 6 bars on the cold water inlet (ZW). No valve should be placed between the tank and the valve. The valve must be positioned so that leaks are visible.

How often to check the magnesium anode?

The anode must be checked every 12 months and replaced every 18 months. It is a wear part that protects against corrosion.

Can I use an electric heater with this tank?

Yes, the tank is equipped with a 1 1/2" threaded opening for an electric heater (e.g. GRW-1.4/230). The maximum heater length is 430 mm.

How to purge the buffer tank during filling?

Use a vent on the central heating circuit supply and at the highest point of the coil. Open the filling valves: air will be automatically evacuated.

What to do in case of water leakage from the tank?

Immediately close the cold water valve and the shut-off valves of the heating circuit, then contact after-sales service.

Why does water drip from the safety valve?

A slight drip is normal and indicates the valve is working. Never block it, as it could cause dangerous overpressure. If it does not drip at all, check its operation.

What is the recommended hygienic temperature?

It is recommended to periodically heat the water above 70 °C for hygienic reasons (prevention of legionella).

Do I need to drain the tank to change the anode?

Yes, close the cold water valve, open a hot water tap and the drain valve. Let the water drain to a level low enough to access the anode without flooding the room. Then unscrew the cap and the anode.

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.

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).
