INTRODUCTION
Advance Electric Thermal Store Systems are perfect for installations where
oil or gas is not available or preferred such as rural dwellings or modern
apartments.
No flues are required and the unit is quiet in operation .
Off peak tariffs can be utilised and all units are fitted with two 3kW immersion
heaters. The unit is designed to make use of off-peak tariffs. The top heater
is for top-up during peak tariff times. If only one immersion heater is used
for single tariff or low load preferences, please connect only the bottom
heater. This is a hot water only thermal store.
Mains pressure hot water is provided safely at 20 litres per minute provided
an adequate service is connected to the unit. This enables power showering
without a pump and fast bath filling.
The unit can be fitted and left isolated from the filling point if it is not
possible to fit an overflow.
The blending valve can be orientated to right or left hand hot water service.
Loosen the compression nuts, move valve and re-tighten the nuts.
The unit can be positioned anywhere within the property, even below hot
water outlets, on a flat even surface.
Do not site in aggressive environments or areas subject to frost.
Please note that the unit must be installed in a position where it can be
serviced and maintained in the future. 200mm top access should be allowed
for. Please also take into account the weight of the unit when full and
ensure that the floor can take the load.

INST
PIPEWORK
ALLATION
The unit must be installed to meet current best practice by a person
competent to do so.
Incoming mains of 22mm with a pressure of 2 bar or above is recommended
for best performance. Lesser pressures/pipe diameters will compromise
performance; this must be taken into account as the decision rests with the
installer/householder.
Incoming pressures of more than 3 bar must be controlled at 3 bar by a
pressure reducing valve (Not supplied).
In hard water areas where concentrations exceed 200ppm a suitable scale
reducer must be installed. The choice is left to the installer to suit local
conditions. Chlorine levels must be below 200ppm.
If the cold service to the ballcock in the cold section is turned off or
disconnected it will not be necessary to fit an overflow, make sure that
the cold section has a 50mm depth of water. Cap the overflow connection
with a 22mm push-fit or compression end stop to prevent evaporation.
For additional protection a float switch can be used connected to a
motorised two port valve on the cold inlet. This is available as a kit from
Advance - please ask for AA0300.
If the overflow is connected it must be in line with current practice.
A metal overflow should be fitted. Push fit or solvent weld are not
recommended. Discharge must be to a safe point. We also recommend
that the ball valve is isolated even if an overflow is fitted.
Inhibitor must be added via the top of the store to manufacturers’
recommended dosage.

In order to comply wit Part L Building Regulations it is necessary to
insulate any ot water (primary and secondary) pipework wit in one metre
of t e cylinder. Guidance is given in t e Table 5 (Page 20) of t e 2013
Domestic Heating Compliance guide. Insulation values for t e most popular
pipe sizes are reproduced below.

USINGT H E U N IT
COMMISSIONING
ALL JOINTS MUST BE TESTED AS THEY CAN LOOSEN IN TRANSIT.
The blending valve is set to maximum. See manufacturer’s leaflet if
adjustment is required.
The immersion heaters are rated at 3kW each, and should be set at 75oC
There is a thermal cut out on the thermostat. This may trip from time to
time and need to be re-set. Use only approved replacements.
The expansion vessel is charged at 3 bar and acts as a shock arrestor to
prevent water hammer and takes up expansion in the internal heat exchanger.
Thermal store units normally provide years of trouble free life, however they
should be serviced periodically. Advance recommends a service at least
every two years. It is important that the store temperature is maintained.
It is critical that the water level is checked if the unit doesn’t have the cold
service connected to the ballcock. About 50 mm depth in the cold section
is required. The transparent vent pipe acts as a sight glass to check water
level without removing the top. Simply open the valve on the flexible hose
to re-fill the unit.
Do not allow water levels to drop below the immersion heater as it will fail
if switched on in air.
Please note that if you are using one immersion heater only, it must be the
lower one otherwise performance will be compromised.
