SITING THE UNIT
The CENTERSTORE cylinder must be vertically fl oor
mounted. Although location is not critical, the
following points should be considered:
• The CENTERSTORE cylinder should be sited to
ensure minimum dead leg distances, particu-
larly to the point of most frequent use.
• Avoid siting where extreme cold temperatures
will be experienced. All exposed pipe work
should be insulated.
• The discharge pipework from the safety valves
must have minimum fall of 1:200 from the unit
and terminate in a safe and visible position.
• Access to associated controls and immersion
heaters must be available to provide for the
servicing and maintenance of the system.
Where these controls are installed against a wall
a minimum distance of 250mm must be left
(see Fig. 1).
• Ensure that the fl oor area for the CENTERSTORE
cylinder is level and capable of permanently
supporting the weight when full of water.
(see Table 1)
WATER SUPPLY
Bear in mind that the mains water supply to the
property will be supplying both the hot and cold
water requirements simultaneously. It is recom-
mended that the maximum water demand is
assessed and the water supply checked to ensure
this demand can be satisfactorily met.
Note: A high mains water pressure will not always
guarantee high fl ow rates.
Wherever possible the mains supply pipe should be
22mm. We suggest the minimum supply require-
ments should be 1.5 bar pressure and 20 litres per
minute fl owrate. However, at these values outlet
fl ow rates may be poor if several outlets are used
simultaneously. The higher the available pressure and
fl ow rate the better the system performance.
The CENTERSTORE cylinder has an operating pres-
sure of 3.5 bar which is controlled by the cold
water combination valve assembly. The cold water
combination valve assembly can be connected to a
maximum mains pressure of 16 bar.
OUTLET/TERMINAL FITTINGS (TAPS, ETC.)
The CENTERSTORE cylinder can be used with most
types of terminal fi ttings. It is advantageous in many
mixer showers to have balanced hot and cold water
supplies. In these instances a balanced pressure
cold water connection should be placed between
the 2 pieces of the cold water combination valve
assembly (see Fig. 2). Outlets situated higher than
the CENTERSTORE cylinder will give outlet pressures
lower than that at the heater, a 10m height difference
will result in a 1 bar pressure reduction at the outlet.
All fi ttings, pipework and connections must have a
rated pressure of at least 6 bar at 80°C.
LIMITATIONS
The CENTERSTORE cylinder should not be used in
association with any of the following:
• Solid fuel boilers or any other boiler in which
the energy input is not under effective
thermostatic control, unless additional and
appropriate safety measures are installed.
• Ascending spray type bidets or any other
class 1 back syphonage risk requiring that a type
A air gap be employed.
• Steam heating plants unless additional and
appropriate safety devices are installed.
• Situations where maintenance is likely to be
neglected or safety devices tampered with.
• Water supplies that have either inadequate
pressure or where the supply may be intermittent.
• Situations where it is not possible to safely
pipe away any discharge from the safety valves.
• In areas where the water consistently contains a
high proportion of solids, e.g. suspended matter
that could block the strainer, unless adequate filtration
can be ensured.
