INSTALLATION
ge pipe.
The connection details are shown on fig. 7 -
page 17. The relief valve connections should not be
altered or used for any other type of connection.
Details of the discharge pipe and installation requi-
rements can be seen on drawing no. fig. 7 - page 17
and Table 2, Page 11.
Before connecting pipework, fit the Siemens safety
shut off zone valve to the primary return outlet.
The incoming cold water supply pipe must be fitted
with a stopcock before the cold water unvented kit.
A drain cock must be fitted between the unvented kit
and the tank.
The unit should be carried into position within its
packaging and on its pallet.
Once in position, the pallet should be removed.
The tank should be installed on a floor designed to
take the weight of the tank when full of water. Each
litre of water weighs 1 Kg. The actual water content
of each tank should be added to the tank weight to
obtain the total weight of the tank when full to ascer-
tain if the floor is of suitable construction.
300mm clearance should be left on the top of the
tank for access to the anode and inspection door.
No valve shall be fitted between the tank and the ex-
pansion valve.
No other immersion, other than our EBS-1
Immersion Heater should be used on our EBS-1
cylinders.
The EBS-1 range of cylinders is ideally suited for
connection to our Geminox boilers to match the coil
ratings. However, connection to non - Geminox
boilers can be carried out if required. Please
contact our Technical Department for installation
assistance on + 44 (0)1372 722277.
To flush through the tank, simply open inspection
door, disconnect unvented kit and flush through the
tank to the drain by using a hose through the inspec-
tion door.
• This unit is only to be used with our oil or gas
boiler with a thermostatic control. It should not
be used with a solid fuel appliance.
• Please note that if a secondary circuit is used
then an additional expansion vessel may be
required.
• In hard water areas you should not exceed
60°C as a store temperature.
Commissioning
• Check all pipe connections for tightness. Close
drain cock.
• Check pressure(s) in expansion vessel(s) 3.5
bar. Recharge if necessary.
• Fill primary circuits, vent and check for leaks.
• Chock open P&T valve on top of tank (by fitting
manual lever).
• Open stopcock and fill tank with water until if
freely discharges through the outlet from the P
& T valve.
• Remove chock and close P&T valve.
• Test delivery of water from tank by opening
and running all taps, both hot and cold water
and any other water discharges points
(showers etc).
• Check operation of expansion relief valve on
Cold Water Supply kit by lifting manual release
lever and discharging water.
• Check all pipework and connections for leaks
Heating of tank by the boiler
Check any programmers are calling for HOT
WATER. Set hot water thermostat on tank to
Maximum. Run heating boiler until the temperature
gauge on the cylinder indicates approximately 50°C.
Turn down the hot water thermostat and check that
motorised valve closes and loading pump stops.
Check that the boiler shuts down. If the boiler is also
feeding a heating circuit, make sure that there is NO
demand from the heating circuit (Room Stat,
Programmer, Zone Valve etc).
Heating of tank from electric immersion heater
• Switch on the power supply to the Electric
Immersion Heater.
