Electrical hazard!

Many possible usesMP 6 is a wall-mounted electric boiler with a stainless steel container. The boiler has many possible uses – for example underfloor heating in extensions or conservatories, or an easy way to heat your holiday cottage or detached garage.

The MP 6 can also be used for portacabins, holiday chalets and on camp sites. The possible applications are endless.

Separate systems are betterIf you have underfloor heating, it is better to have separate systems for heating and hot water. This means that the tem-perature of the hot water is independent of the temperature of the underfloor heating system (usually 25-40ºC).

CompactMP 6 is small in size, with a discreet cover making it easy to find a space for.

PowerfulThe boiler has the power to meet the heating requirement for a domestic surface area of 140 - 150 m², subject to insula-tion and ventilation. The boiler is controlled by an onboard thermostat.

CompleteThe MP 6 is supplied complete. Once the water and electricity are connected, it is ready to use. The boiler is equipped with:

- thermostat

- overheating protection

- indicators showing power on and overheat protection trig-gered

- control switch

- circulation pump

- expansion vessel

The installation must comply with the applica-ble regulations and standards.

The boiler is designed for indoor use, fixed to the wall or similar support with the pipes connected underneath.The ambient temperature must not exceed 30°C.The clearance underneath the boiler must be at least 300 mm to allow the immersion heater to be changed if necessary.Hard water with a high mineral content is not suitable for HVAC applications.To avoid corrosion, the pH value should not be too low.The venting pipe from the boiler safety valve leads to a drip collector within the boiler.The applicable regulations state that an installation inspection must be carried out on a system with a sealed expansion vessel, before it is put into operation. The inspection must be carried out by a person qualified for the task. A further inspection is required if any parts or the expansion vessel are replaced.Clamps must be used when the connections are made to prevent damage to the internal pipework.

System principleThe diagram below illustrates the system principle – the actual system must be designed according to the applicable regulations and standards.

A. MP 6 electric boiler, including: safety valve, expansion vessel, circulation pump, pressure gauge, bleed valve and bypass with shut-off valves.

B. Filling/drain valve.C. Shut-off/flow control valves.D. Underfloor heating system.

Expansion vesselExpansion vessel: 2 litres, pressured on delivery to 1.5 bar. The expansion vessel can handle a heating system volume of 70 litres at 60°C and a static height of 5 metres. If the static height or the temperature is lower, the expansion vessel can handle a larger volume. If glycol is added, the capacity of the expansion vessel falls in relation to the quantity of added glycol.

Safety valveThe safety valve, 2.5 bar, is fitted to the boiler and the venting pipe leads to a drip collector within the boiler.

Filling - bleedingThe heating system must be filled with water to a pressure that is higher than the initial pressure of the expansion vessel, 1.5 bar. 2 bar is recommended. When the system is filled with water, it must be bled at the electric boiler and at the pipe manifold.

Flow - bypass valveA reliable flow must be guaranteed, the boiler require a flow of 6.5 litre/min which gives a ∆t at most 10°C.

The bypass valve should be open between 0.25-0.5 turns.

If the valve is:

- Too little open, the pump may be damaged and the risk increases to overheat protection should trip.

- Too much open, the circulation in the heating system be-come too small.

Shut-off valves, flow and return to boiler.

Adjusting valve, unscrew the protective cover for access.

Pipe installation

Electrical installation must be in accordance with the applicable regulations, under the supervision of an authorised installer.

The boiler must not be connected to the power supply before it is filled with water. An all-pole circuit breaker must be installed ahead of the boiler. The ambient temperature must not exceed 30°C.

After installation, check with the installer that the system is in perfect working order. Ask the installer to demonstrate how to operate and care for the system. The boiler and the heating system must be filled with water before the switch is set to on. The boiler cover must be fitted while the boiler is running.

Regularly check the amount of water in the drip collector for the bleed water from the safety valve. Important in a new system.

Temperature settingsSet the thermostat to a suitable temperature. The maximum temperature for a concrete floor is about 30°C and for a wooden floor it is about 40°C. The temperature re-quirement varies according to the time of year. The boiler works with two effect steps, 3 and 6 kW. At 3 kW are only phases L1 and L2 charged.

Safety valveThe safety valve must be exercised regularly in order to main-tain the safety function. The overflow pipe drain in the collect-ing vessel, 25.

Overheating protectionThe overheating protection is triggered when the boiler temper-ature exceeds 80°C. You can reset the device from the control panel after the boiler temperature has fallen to below 65°C.

Always check the reason for overheating.

If there is a risk of freezingIf the system will be turned off for an extended period, think about the risk of freezing. All the water in the system must be drained if there is a risk of freezing, and the power supply to the boiler must be cut. Alternatively, the correct quantity of anti-freeze can be added to the heating system. The boiler must not be put into operation if any part of the heat-ing system is suspected of being frozen. Call the installer.

ThermometerThe thermometer shows the temperature on the flow side of the boiler.

Expansion vesselThe initial pressure of the expansion vessel must be checked annually, see the data plate on the expansion vessel.

Water pressure in the systemThe boiler cover has to be removed in order to check the pres-sure in the heating system. Regularly check that there is sufficient water in the system. The pressure gauge must read 0.5 - 2.0 bar. The volume of water changes with the temperature, and this affects the pressure. The higher the temperature the greater the volume and the higher the pressure. The expansion vessel takes up the changes in volume.

Check the water pressure in the system regularly.

BleedingAir may remain in the system for a while after installation, so water may need to be added.

Always disconnect the power supply to the boiler before: • draining the boiler water • accessing the automation cabinet or units

powered by the boiler
