IMPORTANT
On twin coil cylinders the
Electrastream tri-core heater must
be fitted to the upper immersion
BEFORE STARTING THE INSTALLATION OF THE ELECTRASTREAM CHECK ALL COMPONENTS HAVE
heater tapping.
BEEN DELIVERED AND ARE IN SATISFACTORY CONDITION - Refer to 1-3 .
1-4.6 Output
The tri-core heater provides 9kW (30,000 Btu) for heating and hot water.
1-4.7 Scale Protection
IMPORTANT All installations should have a scale protection device fitted
and in areas known to have hard water, a water softening device is
strongly recommended. The cylinder is not guaranteed against damage
caused by scale. Higher water temperatures of 65°C and above can
cause excessive scale.
GAH recommend and promote the use of scale prevention devices and water softeners in
ols ols ols ols
areas that are known to have hard water. Installed correctly they prolong the life of
equipment and help prevent limescale formation in the pipework. Water softeners
provide the advantages of soft water, as well as preventing scale build up on taps and
shower heads.
Water softeners and any mains fed system must be of adequate capacity and should be
installed with suitably sized hoses to prevent any possibility of flow reduction.
1-4.8 Frost Protection
When planning the installation location of both the accumulator and the unvented
cylinder, consideration must be given to the risk of frost and the use of frost protection.
The design of the accumulator gives it a degree of frost protection enabling it to be
located within the dwelling, loft space or garage without further protection.
The cylinder can also be installed within the dwelling or loft space without further
protection.
Cylinders or accumulators must have frost protection when they are installed where low
temperatures could be a potential problem. Cylinders can be protected by a frost
thermostat.
To comply with Building Regulations, all necessary pipework must be suitably lagged.
1-4.9 Handling and Storage
The Electrastream system will be delivered fully wrapped and palleted.
Lift the package carefully using a safe and suitable lifting method.
Keep the packaging intact and store in a secure dry and weatherproof area prior to
installation.
The three elements of the tri-core heater are switched on and off by the Electrasteam
Control Unit. They have a staggered switch on sequence that prevents sudden high load
on the power supply.
The control unit also limits the use of the elements for efficiency.
When the hot water within the cylinder is within 2° of the set (8) Target 65°C, only one
element will be on.
When the hot water within the cylinder is between 2° and 4°C below the set (8) Target
65°C, then two elements will be on.
When the hot water within the cylinder is below 6°C of the set (8) Target 65°C, then all
IMPORTANT
three elements will be on.
