GENERAL REQUIREMENTS
IMPORTANT: THIS APPLIANCE IS NOT INTENDED
FOR THE USE BY PERSONS (INCLUDING CHILDREN)
WITH REDUCED PHYSICAL, SENSORY OR MENTAL
CAPABILITIES, OR LACK OF KNOWLEDGE AND
EXPERIENCE, UNLESS THEY HAVE BEEN GIVEN
SUPERVISION OR INSTRUCTION CONCERNING
THE USE OF THE APPLIANCE BY A PERSON
RESPONSIBLE FOR THEIR SAFETY. CHILDREN MUST
BE SUPERVISED.
SITING THE UNIT
The PremierPlus cylinder must be vertically floor
mounted. Although location is not critical, the
following points should be considered:
The PremierPlus cylinder should be sited
•
to ensure minimum dead leg distances,
particularly 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 mainenance of the system.
Where these controls are installed against a
•
wall a minimum distance of 250mm must be
left (see Fig. 1, page 3).
Ensure that the floor area for the PremierPlus
•
cylinder is level and capable of permanently
supporting the weight when full of water. (see
Table 1, page 3)

WATER SUPPLY
Bear in mind that the water supply to the property
will be supplying both the hot and cold water
requirements simultaneously. It is recommended
that the maximum water demand is assessed and the
water supply checked to ensure this demand can be
satisfactorily met.
NOTE:
A high water pressure will not always
guarantee high flow rates.
Wherever possible the PremierPlus supply pipe
should be 22mm. We suggest the minimum supply
requirements 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 PremierPlus 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 pressure of 16 bar.
OUTLET/TERMINAL FITTINGS (TAPS, ETC.)
The PremierPlus 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 cold water
connection should be placed between the Cold Water
Combination Valve and the PremierPlus water heater
(see Fig.6, page 10). Outlets situated higher than the
PremierPlus 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.
