Commissioning The Unit; Capillary Tube - Dimplex R7 Installation Instructions Manual

8. REASSEMBLY OF THE UNIT
i) Fit side insulation strips on each side between the cold tails and
the inner front panel - Fig. P.
ii) Replace inner front insulation. Ensure that when insulation is
fi tted the hole for the charge controller lines up with the grooves in
the second and third layer of bricks down from
the top. In the R15/104 unit only, the charge
controller is entered in grooves between the
fourth and fi fth layers from the top - Fig. Q

iii) Replace inner front panel and secure with screws. Ensure that
hole for charge controller in this panel lines up with that in the inner
front insulation.
iv) Reconnect the fusible links and check for electrical continuity.
Ensure that the fusible links fi t properly into the support bracket.
v) A special ceramic tube houses the phial of the input controller.
Fit the ceramic tube by inserting it through the hole in the safe door
pushing it in the full length - Fig. R.
vi) Fit the input controller phial into the ceramic tube until the end

9. COMMISSIONING THE UNIT

When the heater has been completely assembled it will be necessary
to commission the unit. This entails checking that the unit is functioning
properly, that the airfl ow delivered is correct for the installation and
that the outlet air temperatures are acceptable.
Fig.P
Fan speeds and outlet temperatures are factory preset but the fan
speed can be adjusted by following the points below;
i) Switch on the heater with the charge controller set at Max and
allow to charge up overnight.
Sealing
ii) Switch 'on' the fan at 'Boost' speed and run for fi fteen minutes.

iii) Check the airfl ow delivered and if incorrect adjust as follows;
Switch off mains supplies (both restricted and unrestricted).
Remove fi lter panel.
band from the left on the fan speed resistor (see Fig. D) and move
towards the left-hand end to increase the fan speed, towards the
right-hand end to decrease the fan speed. Tighten up the band on
the resistor and reassemble the heater. Switch on and check the
airfl ow. Repeat the adjustment if necessary.
iv) Switch the fan on to normal speed. After 15 minutes check the
airfl ow delivered, if it is incorrect adjust as above, but in this case it
is the second moveable band from the left which alters the speed.
