Mains Water Supply
The MULTI
flow
’s performance is
largely related to the cold water supply pressure and
flow rate incoming to the property.
•
The mains supply to the unit should ideally be in a minimum of
22mm diameter
but will work with 15mm if there is adequate pressure and flow rate.
•
The MULTI
flow
will operate with a minimum incoming mains pressure of
1.0
Bar
and a
minimum flow rate of 20 Litres/minute
.
Careful consideration should be
made to ensure the pressure of hot and cold supplies are balanced.
•
An incoming pressure of
2.1 Bar
is the most optimal for performance.
•
If the incoming pressure
exceeds 3 Bar,
then a pressure reducing valve must be
fitted after the stopcock of where the incoming cold supply enters the property.
•
No Pressure Reducing Valve or Check Valve should be fitted
within 2 metres
of
the Cold Inlet to the MULTI
flow
Coil.
•
If the flow rate exceeds
15 Litres per minute
at any tap, it should be restricted
to maintain the performance of the system as a whole.
Immersion Heaters
•
Immersion Heaters are preset to ensure the store temperature reaches
70°C
(maximum
75°C
) once the unit is heated.
•
The Immersion Heater thermostats are preset with the control setting at
70°C
and the high limit setting at
90°C
. The control setting can be lowered or
increased as required for the installation requirements.
•
If in any doubt of how to set the Immersion or what temperature we would
advise for specific installations, please contact us on
01592 611123
.
•
All Immersion Heaters should be wired by a qualified electrician as shown
below, for further information refer to literature provided with the immersion;
