SITING THE UNIT
The POTTERTON GOLD cylinder must be vertically
floor mounted. Although location is not critical, the
following points should be considered:
• The POTTERTON GOLD cylinder should be sited
to ensure minimum dead leg distances, par-
ticularly 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 floor area for the POTTERTON
GOLD 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 flow 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 flowrate. However, at these values outlet
flow rates may be poor if several outlets are used
simultaneously. The higher the available pressure and
flow rate the better the system performance.
The POTTERTON GOLD cylinder has an operating
pressure 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 POTTERTON GOLD cylinder can be used with
most types of terminal fittings. 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 POTTERTON GOLD 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 fittings, pipework and
connections must have a rated pressure of at least
6 bar at 80°C.
