Redring MS6 Installation And Operating Manual

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 (in accordance with EN 1487 or EN 1489),
then it must be bought and fitted separately. For mechanisms operating in
accordance with 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
10 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 be always
open to the atmosphere (not immersed in water). we
recommend the use of a tundish.
The boiler 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 de-pressurize the system before removing
the unit from the wall.

SYMPTOM
POSSIBLE CAUSE
ACTION
Pressure relief valve dripping
/ running very hot water all
the time
Thermal cut out and
thermostat have failed.
Mains pressure is above
600 kPa (6 bar)
Call Installer/suitably
qualified person.
A pressure reducing valve
must be fitted.
Pressure relief valve dripping
/ running all the time.
Mains pressure is above
600 kPa (6 bar).
Call Installer/suitably
qualified person.
A pressure reducing valve
must be fitted
Dripping while unit heating.
Not enough pipe work for
expansion (1.7m required)
Stop-cock, non-return valve
or pressure reducing valve
has been fitted within the
distance required for
expansion (see page 8,
diagram 5).
If an expansion vessel has
been fitted, the charge may
have failed
Call Installer/suitably
qualified person, and modify
installation
(see page 8, diagram 5).
Replace accordingly.
Call suitably qualified
person.
No hot water.
Thermal cut-out has
operated.
The heating element has
burnt-out.
The thermostat is faulty.
Replace accordingly.
Call Installer/suitably
qualified person
Milky water.
This is a result of heavily
limed and oxygenated water
being heated.
This is harmless and the
cause is the water and not
the heater.
No water at all.
Mains water supply turned
off.
Valve incorrectly fitted.
Debris in the mains.
Switch on mains water
supply.
Call Installer/suitably
qualified person.
Indicator lamp does not
illuminate
No power to unit
indicator damaged
thermal cutout operated
Check unit switched on
Call Installer/suitably
qualified person to check
wiring & indicator lamp
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
