sioning or any modifications must be carried out
by a competent, qualified engineer in accordance
with the relevant requirements.
Respect the electrical connection plan! (§ 7 page 20)
- Before installation: make sure the appliance is
turned-off at all points. Secure against involuntary
re-triggering.
- The domestic hot water tank must only be used to
heat water for domestic purposes.
Statutory conditons for installation and maintenance in residential buildings.
• Decree of 23 June 1978 and modifying decree of 30 November 2005
Heating instructions, hot water supply, layout
and safety rules. In particular, ensure that the
maximum temperature for distributing hot wa
-
ter is respected.
A thermostatic mixer must be placed on the do-
mestic hot water distribution to limit the temperature at the drawing point (50 °C).

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 requirements 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 th e 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.

INSTALLATION
• Turn Elec tric Heater thermostat up and down
to check that heater is turning on and off
correctly.
• Select the desired hot water temperature.
The total fuse rating for the immersion heater is
13.04A, a suitable protective device should be
selected. The boiler should be protected by a fused
spur with a cartridge fuse of no higher than 3A.
Please Note
The Geminox range of products are designed to be
used in installations where the complete system is
supplied by Geminox therefore when used in con
junction with other products some slight altera tions
to the Electrical installation may have to be made.
Important Notice
When the system installed is "Unvented" controlling
the Zone valve by way of the cylinder and overheat
thermostats, follow the steps on
section 6.2.3 page 12 in this instance the zone valve is called the
"Safety shut off zone valve", the valve is supplied
with the Unvented Kit and must be installed.
The safety shut off zone valve is an important
safety device of the unvented EBS-1 tank and
must be installed. Fit the valve to the return con
nection of the tank connection No. 4. The valve
is to be controlled via the brown wire of the tank
top cable. Please find the attached photos and
fig. 10 how to connect the "Safety shut off zone
valve".
Safety Discharge Pipe from Tundish
See Table 2 below for sizing details of safety discharge pipe from our tundish.
Worked example :
The example below is for a G 1/2 temperature relief
valve with a discharge pipe (D2) having 4 no. elbows and length of 7m from the tundish to the point
of discharge.
From table 2
Maximum resistance allowed for a straight length of
22mm copper discharge pipe (D2) from a G 1/2 tem
-
perature relief valve is 9.0m.
Subtract the resistance for 4 no. 22mm elbows at
0.8m each = 3.2m
Therefore, the maximum permitted length equates
to : 5.8m
5.8m is less that the actual length of 7m, th erefore
calculate the next largest size.
Maximum resistance allowed for a straight length of
28mm pipe (D2) from a G1/2 temperature relief val
-
ve equates to 18m.
Subtract the resistance for 4 no.28mm elbows at
1.0m each = 4m
Therefore the maximum permitted length equates to
: 14m
As the actual length is 7m, a 28mm (D2) copper p ipe
will be satisfactor y.

INSTALLATION
When the system installed is "Unvented" it is
necessary to fit the "unvented kit" on the cold
water supply. The "Unvented kit" contains
pressure reducing valve, non-return valve,
pressure relief valve and optional use balanced
cold water connector. It is good practice to fit
the "unvented kit" above the top level of the
EBS-1 tank. In this way if it is required to replace
the "unvented kit" it is not necessary to drain all
tank. Please find below how to install the
"unvented kit"

V - COMMISSIONING
1 - FILLING THE INSTALLATION WITH WATER
- Filling the installation:
• before you fill, rinse the installation's pipes,
except for the tank.
Refer to the boiler's manual
- Filling the tank:
• fill the domestic hot water production system
using the installation's safety control box (8,
fig. 9 - page 19 - chapter IV - INSTALLATION)
taking care to open a hot water tap.
• After th e system is full, check that the tank's
access flap is tightly shut.
- Drain the tank and the installation thoroughly
before filling.
2 - VERIFICATIONS PRIOR TO COMMISSIONING
- Check that the tank access flap is tight and
waterproof (8,
fig. 2 - page 8 - chapter III -
TECHNICAL SPECIFICATIONS,
- Check the waterproofing of the various seals and
connectors in the installation,
- Check that the primary circuit is drained,
- Check that the electrical connection is correct.
- To guarantee the stated performances, check
that the security control box's cold water tap is set
to obtain a maximum flow rate for the hot water of
the value indicated in
section 1 - page 6 -
chapter III - TECHNICAL SPECIFICATIONS).
3 - USER INFORMATION
The installer must train the user in how the
appliance works. In particular, the user must be
informed of the role and operation of the safety
mechanisms and the need to have the appliance
maintained regularly by a qualified profession a l.
WARNING TO THE USER
Do not remove or adjust any component part of
unvented water heater :contact the installer.
If this unvented water heater develops a fault, such
as flow of hot water from the discharge pipe, switch
the heater off and contact the installer.
- 23 -
COMMISSIONING
4 - COMMISSIONING
- Commissioning the boiler,
- Adjust the domestic hot water temperature
setting thermostat (9,
fig. 12) according to the
selected temperature -
Recommended setting 55/60 °C (read on th e
thermometer ( 10)). This setting is used to limit
heat loss and scaling while preventing legionella
from spreading if the domestic cold water is
contaminated. A temperature of less than 60°C
also limits the spread of limescale (refer to
section 1 - page 24 - chapter VI MAINTENANCE)
- Set the boiler's thermostat to a temperature
greater than that of the domestic hot water
production system.
Always set to a value greater by at least 1 0°C
than the desired storage temperature in the
domestic hot water production system, but
never to a value of over 85°C to avoid any
unplanned triggering of the thermal safety
devices (ideal boiler setting = 75°C, domestic
hot water production system = 60°C).
- When the boiler is fitted with electronic regulation,
the domestic hot water temperature is set on the
boiler's regulator.
Refer to the Commissioning chapter in the boiler's
technical instructions.
Leave the setting thermostat (9) on
"Maximum" when tank is heated by a
boiler.

VI - MAINTENANCE
An annual inspection of the tank is compulsory. It
must be carried out by a qualified professional.
All spare parts will be original parts and must be
ordered using the references in
chapter VII -
PARTS LIST - page 26, specifying the appliance
type and serial number.
Disconnect the electricity supply before
carrying out any action on the tank.
1 - TANK MAINTENANCE
- In very hard water regions
(TH > 30) if the tank needs to be cleaned
frequently, the ideal solution is to add a water
softener to the installation or to install an antilimescale treatment system on the installation's
cold water inlet.
Adjust the domestic hot water temperature to
a value of less than 60°C. Limescale spreads
quicker above 60°C.
- If the tank is inspected through the access flap (8,
fig. 13) provided for the purpose:
• remove the protective plate (22) - remove the
3 screws (23),
• remove the insulation ( 18),
• remove the access flap (8), flap flange (19) and
seal (20),
• replace the flap (20) each time it is removed,
• refit the assembly,
• after filling:
. check that the tank is watertight,
. drain the tank thoroughly.
2 - DRAINING
The hot water tank may be drained by siphoning
through the safety control box as long as this is
installed on the lower part of the tank.
Provide an air inlet by opening a hot water tap.
3- P&T VALVE
Check the operation of the P&T valve every year
and rinse it by briefly bleeding it several times.
A safety valve that is not working correctly may
cause damage due to excessive pressure.
If necessary, replace it if it stops working correctly or
begins to leak (permanent flow through the valve).
