Insulation and sealing materials are used in the construction
of the Electrastream cylinders. Units are sealed and when
used in the manner for which they are intended the insulating
and sealing materials do not present any known hazard.
However always observe the following recommendations:-
1.
Avoid inhalation of fibres or dust, wear face mask.
2.
Avoid eye contamination by fibres or dust - wear eye

The Electrastream hot water cylinder has a Temperature/Pressure Relief Valve (TPRV); in
the event of the pressure within the cylinder becoming too high, the TPR Valve will vent.
The cylinder connection for the TPR valve must not be used for any other purpose.
The cylinder connection for the TPR valve must not be used for any other purpose.
The cylinder connection for the TPR valve must not be used for any other purpose.
The cylinder connection for the TPR valve must not be used for any other purpose.
The cylinder connection for the TPR valve must not be used for any other purpose.
The heating system has its own Pressure Relief Valve (PRV) located adjacent to the
heating expansion vessel; in the event of the pressure within the heating system
becoming too high, the PRV will vent.
The combination valve also includes a PRV.
A Tundish will be fitted in the system, this should be located in the same space or
compartment as the hot water cylinder. This device provides an air break when pressure
is being vented from the cylinder TPRV.
The heating system PRV is normally also connected to the cylinder Tundish, alternatively
it may have its own.
When pressure is being vented, water/steam will be evident at the Tundish and from the
discharge pipe of the Tundish.
In the event of hot water/steam being emitted at the discharge pipe or
tundish, switch the system Off and contact installer - refer to Fault
Finding section 7.
The Mixing Valve will be fitted in the supply to the hot taps/outlets, it may be in a different
location than the cylinder. This valve mixes hot water from the cylinder with cold water to
provide hot water of a constant temperature at the taps.
The recommended maximum hot water temperature at the taps is 60ºC.
The recommended setting of the valve is between No. 4 and 6 (49º to 58ºC).
The Mixing Valve is factory set to the following approximate mixed outlet temperatures:-
Knob Position
Min
Output Temp. ºC
27º
The mixing valve may have specific servicing requirements - refer to manufacturers
instructions.
Higher water temperatures of 65°C and above can cause excessive scale in hard water
areas.
WARNING
Do not set the water temperature too high as this can cause scalding
especially to the young and old.

The Cylinder Tri-Core Heater, Pump, Thermostats and Contactor
Box all have electrical supply of 230V (enough to endanger
life).
Always isolate before connection, adjustment, servicing and
repair.
When the Tri-Core Heater cover is removed high power live
electrical terminals are exposed.
ISOLATE THE TRI-CORE HEATER BEFORE REMOVING ITS
COVER.
Earth protection - Earth Continuity Conductors must be fitted
and must comply with IEE Wiring Regulations.
