• Connecting the water heater to the electric mains via a plug must only use the plug supplied.
• If the water heater will not be used for longer than 3 days and the temperature in the premises drops below 4°C, the water in the water heater must be drained to avoid any possible damage to the appliance.

IMPORTANT SAFETY INFORMATION
Your MS Heater has been designed for convenience, economy, and safety of use, provided that it is installed, used, and maintained in good working order and by our instructions and recommendations.

• All wiring and installation must be supervised by a suitably qualified person.
• THIS APPLIANCE MUST BE EARTHED.
• The installation must be by the current edition of BS.7671 (the “IEE Wiring Regulations”) and “Part P” of the “Building Regulations” in force at the time of installation. Installations must also conform to any local regulations in effect.
• This appliance is intended to be permanently connected to the fixed electrical wiring of the mains supply with its dedicated supply OR using the plug provided.
• Ensure that the mains water supply meets the requirements listed.
• This appliance MUST NOT be fitted where it may be subjected to freezing conditions. DO NOT switch the appliance on if you suspect it of being frozen. Wait until you are sure it has thawed out.
• The unit MUST NOT be mounted upside down.
• The 6 6-bar pressure Relief Valve (supplied) MUST BE fitted in the Inlet feed to the unit.
• In ALL cases the DIELECTRIC JUNCTIONS MUST be connected to the heater before any other connection is made. This is very important as they protect the heater against potential aggressive corrosion.
• Isolate the mains electrical and water supply before removing the front cover of the appliance.

For safe operation, the safety pressure relief valve must undergo regular cleaning and inspection for normal functioning, the valve must not be obstructed, and for regions with hard water, it must be descaled as necessary. This service is not provided under warranty maintenance. All alterations and modifications to the water heater’s construction and electrical circuitry are undertaken entirely at the purchaser’s risk and are NOT recommended. Any such alterations or modifications may invalidate the appliance’s warranty.
If the power cord is damaged, it must be replaced immediately by an appropriately qualified person, to avoid any risks

DESCRIPTION OF THE APPLIANCE

• The appliance consists of a body, flange, plastic control panel & safety pressure relief valve.

• The body consists of a steel reservoir (water tank) and plastic housing (outer shell) with thermal insulation placed in between, and two threaded pipes for the cold water supply IN (marked with a blue ring) and hot water discharge OUT (marked with a red ring). The inner reservoir is steel protected against corrosion by a special glass-ceramic coating.
  The flange is fitted with a heating element and a magnesium anode. The flange is fixed to the water tank with bolts.

• The element heats the water in the tank and is controlled by the thermostat, automatically maintaining the preset temperature. The plastic control panel incorporates an adjustable thermostat and an indicator light.

• The thermal cut-out switches off the power supply should the water temperature reach excessive values. If this device is activated, you should call our service helpline (See page 11 for details).

• The signal light on the control panel indicates the unit is heating.

• The magnesium anode provides additional anti-corrosion protection to the internal tank. The Pressure relief valve protects the appliance from higher than the allowed value (6.0 bar) during heating (note: pressure will increase when temperature increases), by releasing the excess pressure through the drain outlet.

• Excess water exiting into the drain during the heating process is a normal event that must be taken into consideration when the heater is installed.

ATTENTION! The safety valve cannot protect the appliance in the event of water mains pressure exceeding the rated pressure stated for the appliance (6 bar).

INSTALLATION PROCEDURE

We recommend installation of the device close to the likely outlet (i.e., Tap) where hot water is used, to reduce heat losses. The selected installation location must be clean and dry at all times. The appliance is affixed to a wall using a mounting bracket which the unit hooks on.

• The unit should be installed as near as possible to the outlet points, to reduce heat loss along the pipes.
• This water heater should be mounted on a solid wall preferably where it is close to the power socket and water source.
• Ensure the heater is at least 200mm from the floor this will leave space for maintenance when necessary.
• Mark the wall, drill the holes (010mm), and fit the bracket (62mm centers). (diagram1)

IMPORTANT: MS water heaters are designed for installation with the outlet/inlet pipes pointed upwards (to the ceiling) only. Under no circumstances should these units be fitted upside down, with the outlet/inlet pipes pointing towards the floor. (Note: Diagrams show MS6 unit)

Hook unit on the wall bracket (diagram 3) ATTENTION! Do not place objects, which are not waterproof under the appliance under any circumstances.

Water heater connection to the water supply system
All connections are ½”BSP. Fasten the dielectric junctions to both Hot and Cold connections.

IMPORTANT note that in ALL cases the DIELECTRIC JUNCTIONS MUST be connected to the heater before any other connection is made. This is very important as they prevent an electrolytic reaction from occurring and safeguard the heater against potential aggressive corrosion. Only the use of copper pipe is recommended for connection to the heater. If any other material is used it must be able to withstand 90°C at 8 bar pressure for long periods. Fit the Pressure relief valve in the cold water feed to the unit close to the inlet (blue) and install the pipework from the valve to drain via a tundish. When water is heated it expands. In a small unvented water heater of this type, the expansion can normally be accommodated back into the cold water mains, as indicated in the water regulations. This heater requires a minimum distance of pipe before the nearest cold water draw-off. (see diagram 5).

IMPORTANT. If the mains supply to the unit is more than 6 bar a pressure- reducing valve will be required to prevent the pressure relief valve from discharging all the time.

IMPORTANT. DO NOT fit any stop-cocks or non-return valves within the distance required for expansion. The minimum distance is for a 15mm pipe this can be approximately halved for a 22mm pipe. Where this is not possible the installer will need to fit a set of cold water controls. Which comprises a pressure-reducing valve (set at 3.5 bar), a nonreturn valve, and an expansion vessel charged to 3.5 bar, the expansion is then accommodated in the vessel. (see diagram 6)

PERIODIC MAINTENANCE
In hard water areas, with normal use, limescale will be deposited upon the healing element’s surface. Over time, this builds up and lessens the heat exchange between the heating element and water, which could make the system run hotter and the thermostat may switch on and off more frequently. Redring recommends preventive maintenance of your water heater at least EVERY year by a qualified technician. Protective maintenance must include cleaning and inspection of the anode protector, and replacing it if necessary.
To clean the appliance, use a damp cloth. Do not clean with abrasives or detergents that contain solvents. Do not pour water over the appliance.

IMPORTANT!! The mounting of the pressure relief valve supplied with the water heater is compulsory. It must be installed on the cold water supply pipe. Exception: If local regulations (norms) require the usage of another protection valve or mechanism (by EN 1487 or EN 1489), then it must be bought and fitted separately. For mechanisms operating by EN 1487, the rated operational pressure must be no more than 0.7 Mpa (7 Bar). For other protection valves, the pressure at which they are calibrated must be 1 bar lower than the one marked on the appliance. NB- In the circumstances above only, the safety valve which the appliance is supplied with should not be used.

• ATTENTION! Any other type of device should not be fitted between the pressure relief valve and the appliance.
• ATTENTION! Fixing the pressure relief valve to threads longer than 1 mm should not be attempted as this could damage the valve.
• ATTENTION! The pressure relief valve and the pipe between the valve and the water heater must be protected from freezing. During valve discharging – its free end must always be open to the atmosphere (not immersed in water). We recommend the use of a tundish.

The water heater is filled with water by opening the isolation valve on the cold water supply system and the hot tap on the sink. After the filling process is complete, a constant stream of water should flow from the hot tap. Now you can shut the hot water tap on the sink. If emptying the water heater, you must first isolate the power supply then close the service valve, and open the hot tap to depressurize the system before removing the unit from the wall.

MAINTENANCE

Sacrificial Anode
To obtain the best performance from the heater, the sacrificial anode must be checked every year. The magnesium anode protects the water tank’s inner surface from corrosion. It undergoes wear and tear and should be replaced periodically by the user. Redring recommends periodic inspections of the magnesium anode’s condition by a qualified technician and replacement whenever required to keep your appliance working correctly.

Fault finding
If the unit is unsatisfactory, make the following checks before calling out the installer. Any one of these adjustments could restore the performance.

WARNING: SWITCH OFF THE ELECTRICITY AT THE ISOLATING SWITCH BEFORE REMOVING THE COVER TO MAKE CHECKS
