GENERAL REQUIREMENTS
IMPORTANT: THIS APPLIANCE CAN BE USED BY CHILDREN AGED FROM 8 YEARS AND ABOVE AND PERSONS WITH
REDUCED PHYSICAL SENSORY OR MENTAL CAPABILITIES OR LACK OF EXPERIENCE AND KNOWLEDGE IF THEY HAVE
BEEN GIVEN SUPERVISORY OR INSTRUCTION CONCERNING USE OF THE APPLIANCE IN A SAFE WAY AND UNDERSTAND
THE HAZARDS INVOLVED. CHILDREN SHALL NOT PLAY WITH THE APPLIANCE. CLEANING AND USER MAINTENANCE
SHALL NOT BE MADE BY CHILDREN WITHOUT SUPERVISION.
WARNING: Do not switch on if there is a possibility that the water in the heater is frozen.
COMPONENT CHECK LIST
Before commencing installation check that all the components for your PremierPlus SystemFit unit are contained in the
package. The following components are supplied with your PremierPlus Systemt unit:
• Factory tted immersion heater(s) and thermal controls
• Cold water combination valve (comprises pressure reducing valve, strainer, check valve) (supplied loose)
• Factory tted expansion core unit (comprises expansion valve and check valve)
• Potable water expansion vessel (supplied loose) factory tted temperature/pressure relief valve (set at 90°C/10 bar)
• Tundish
• Factory tted indirect thermostat and thermal cut-out
• 2 x 2-port motorised valve
• Primary circulating pump
• Lock-shield ow balancing valve
• Automatic bypass valve
• Primary circuit lling loop
• Primary circuit pressure gauge
• Automatic air vent
• Primary circuit expansion vessel (supplied loose)
• CH/DHW programmer and room temperature sensor (supplied loose)
SITING THE UNIT
The PremierPlus SystemFit unit must be vertically oor mounted. It can be placed anywhere convenient provided the discharge
pipe(s) from its safety valves can be correctly installed. Areas that are subject to freezing must be avoided. Ensure that the
oor is of sufcient strength to support the “full” weight of the unit (table 1, page 5). Pipe runs should be kept as short as
possible for maximum economy. Access to associated controls, immersion heaters and indirect controls should be possible
for servicing and maintenance of the system.
To aid installation the PremierPlus SystemFit is provided with lifting points located in the base and top mouldings. A oor
template is also provided to aid positioning.
If you choose to install the PremierPlus SystemFit in the highest point in the property (e.g. loft space), it is advisable to install
an additional automatic air vent (AAV) (not supplied - available as spare, part number 95 605 050) above the pump to enable
air to be removed from the system. The addition of the AAV is not required if siting the cylinder in a lower position.
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 ow rates.
Wherever possible the PremierPlus Systemt supply pipe should be 22mm. We suggest the minimum supply requirements
should be 1.5 bar pressure and 20 litres per minute ow rate. However, at these values outlet ow rates may be poor if several
outlets are used simultaneously. The higher the available pressure and ow rate the better the system performance.
The PremierPlus SystemFit 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.
