Filling The Unit With Water
Ensure that all fittings and immersion heaters are
correctly fitted and tightened. An immersion heater key
is provided to aid tightening the immersion heater(s)
• Check expansion vessel pre-charge pressure. The
vessel is supplied precharged to 0.35MPa (3.5
bar) to match the control pressure of the pressure
reducing valve. The precharge pressure is checked
using a car tyre gauge by unscrewing the plastic
cap opposite the water connection.
• Check all connections for tightness including the
immersion heater(s). An immersion heater key
spanner is supplied for this purpose.
• Ensure the drain cock is CLOSED.
• Open a hot tap furthest from the cylinder.
• Open the mains stop cock to fill the unit. When
water flows from the tap, allow to run for a few
minutes to thoroughly flush through any residue,
dirt or swarf, then close the tap.
• Open successive hot taps to purge the system
of air.
System Checks
• Check all water connections for leaks and rectify
as necessary.
• Turn off mains water supply.
• Remove the pressure reducing valve head work to
access the strainer mesh, clean and re-fit.
• Turn mains water supply on.
• Manually open, for a few seconds, each relief
valve in turn, checking that water is discharged
and runs freely through the tundish and out at the
discharge point.
• Ensure that the valve(s) reseat satisfactorily.
Solar Primary Circuit
Fill the solar primary circuit following the instructions
provided with the solar hydraulic controls. The cylinder
temperature control probe supplied with the solar
controller must be fully inserted into the pocket in the
lower controls housing and the cable securely clamped.
Heating by the solar primary circuit is controlled by the
solar controller; refer to the manufacturer’s installation
instructions for details of how to set up and connect
the solar primary circuit. The solar controller should be
programmed to give a maximum storage temperature
in the cylinder of 70°C, (60°C is recommended to
minimise scaling).
Secondary heating coil
Fill the secondary circuit following the boiler
manufacturer’s commissioning instructions. To ensure
the cylinder primary heat exchanger is filled, the 2
port motorised valve (supplied) should be manually
opened by moving the lever on the motor housing to
the MANUAL setting. When the primary circuit is full
return the lever to the AUTOMATIC position.
Switch on the boiler, ensure the programmer is set to
Domestic Hot Water and allow the cylinder to heat up to
a normal working temperature (60°C recommended). If
necessary the temperature can be adjusted by inserting
a flat bladed screwdriver in the adjustment knob (located
on front of the thermostat mounting bracket - (see Fig.11
below) and rotating. The minimum thermostat setting
is 10°C.
The adjustment represents a temperature range of 10°C
to 72°C.
Check the operation of the indirect thermostat and 2
port motorised valve and that no water has emitted from
the expansion relief valve or temperature/pressure relief
valve during the heating cycle.
Benchmark Log Book
On completion of the installation and commissioning
procedures detailed in this manual the Benchmark
Installation, Commissioning and Service Record Log,
pages 20 and 21 should be completed and signed off
by the competent installer or commissioning engineer
in the relevant sections. The various system features,
location of system controls, user instructions and what
to do in the event of a system failure should be explained
to the customer. The customer should then countersign
the Benchmark
TM
Commissioning Checklist (page 20)
to accept completion. The service record should be
filled in when any subsequent service or maintenance
operation is carried out on the product.
