USE
Before commissioning, it must be ensured that the piping has undergone a leakage test and that the accumulator is full of water. The tank must be
filled with water to avoid damage to any electrical resistors installed. The operation of the safety valve should be checked every 3-4 months, as its
lack of functioning may cause a hazardous situation. The valve is triggered by turning its knob counterclockwise, allowing water to flow through the
safety valve brick outlet. If this does not happen, the valve is defective and must be replaced.
MAINTENANCE
The operation of the safety valve should be checked every 3-4 months, as its malfunction may cause a hazardous situation. The valve is triggered by
turning its knob counterclockwise, allowing water to flow through the safety valve discharge pipe. If this does not happen, the valve is defective and
must be replaced.
The broken electrical part must be replaced with the original spare part. Maintenance must only be carried out by a qualified
electrician. Paint surfaces can be cleaned with diluted detergents.
To remove the domestic water spirals, remove the coil cover and cut a hole in the insulation behind the lid using a knife. After removing the
insulation, the thread can be removed by opening the bolts on the coil flange.
After removing the lower circulator, the solar coil can be removed through the operating water coil's installation opening, from the inner side. In
addition, the counter nuts of the solar spiral penetrations must be removed from under the surface damper to remove the coil.
TROUBLESHOOTING
•
The boiler does not provide enough hot water.
The higher boiler temperature produces more domestic water, but especially in heat pump heating, the high temperature yield requirement for a heat
pump reduces the efficiency of the pump. See
The operating description of possible actions.
•
The safety valve drips water : NOTE! The drip of the safety valve is generally interpreted as having something wrong with it, even though it is
quite reversed. The safety valve will then work exactly as it should. The drip is caused by the thermal expansion of the water. In renovation projects,
pipes and valves are often replaced when the domestic water system is renewed. In this case, the one-way valve in the network will also be renewed,
through which the increase in pressure has previously been able to escape to other parts of the network. Therefore, the safety valve drops more in
renovation sites than before. Water density is at its highest at + 4 °C. When the temperature is raised or lowered, the volume of water increases. The
coefficient of thermal expansion of the water volume when increasing the temperature from +4 °C to +80 °C shall be 0,0290:
1 Kg H2O (water) + 4 °C at = 1 litre
1 Kg H2O (water) + 80 °C = 1,0290 liter
E.g. 300 kg of water at + 4 °C = 300 liters
300 kg water at + 80 °C = 308,7 litres
In the example, the volume increases by 8.7 litres and this amount is removed through the safety valve.
E.G. 50 kg of water + 4 °C = 50 liters of 50 kg of water at + 80 °C = 51,45 litres
