Refer to Figure 51
a)
Ensure supply voltage is isolated.
b) Drain down the appliance; refer to section 9.24.
c) Close the DHW inlet isolating cock, open a DHW tap at the
lowest point in the system and allow the pressure to dissipate.
Close this tap again.
d) Undo the nut connecting the flow pipe from the main heat
exchanger to the plate heat exchanger, and rotate in an
anticlockwise direction to give access to the filter.
e) Lift out the filter and clean under a tap.
g) Refit the filter, or replace as necessary, and re-assemble in
reverse order; ensure that all joints and seals are correctly re-fitted.
h) If it is suspected that the plate heat exchanger is blocked or is
leaking then proceed as follows:
i) Undo the nut connecting the pipe from the hydroblock to the
plate heat exchanger, and rotate out of the way.
j) Undo the nut connecting the plate heat exchanger to the CH
flow water isolating cock pipe.
k) Undo the nut connecting the plate heat exchanger to the DHW
outlet pipe.
l) Undo the nut connecting the plate heat exchanger to the DHW
water isolating cock pipe.
m) Lift up the plate heat exchanger and remove.
n) Fit the replacement plate heat exchanger, using new case
seals as necessary, ensuring the filter is fitted.
o) Re-assemble in reverse order; ensure that all joints and seals
are correctly re-fitted.
p) Open the isolating cocks and vent air from the system using
the manual air vent. Re-pressurise the system as necessary and
check for water leaks.
Refer to Figure 27
a)
Ensure supply voltage is isolated.
b) Open the drain sump cap, while holding a receptacle beneath
to capture any condensate.
c) Disconnect the condensate drainpipe from the appliance.
d) Undo the two locknuts holding the system in place.
e) Unclip the hose from the support bracket.
f) Detach the condensate drainpipe sump adaptor, by gently
pulling down.
g) Remove the condensate drain system, clean or replace as
necessary.
h) Re-assemble in reverse order; ensure that all joints and seals
are correctly re-fitted.
9.18
CONDENSATE DRAIN SYSTEM
Refer to Figure 24
a)
Ensure supply voltage is isolated.
b) Drain down the appliance; refer to section 9.24.
c) Disconnect the pressure gauge capillary from the pressure
relief valve.
d) Disengage the pressure gauge from the fascia panel, and
remove the gauge.
e) Fit the new pressure gauge and re-assemble in reverse order.
f) Open the isolating cocks and vent air from the system using
the manual air vent. Re-pressurise the system as necessary and
check for water leaks.
9.19
PRESSURE GAUGE
Refer to Figure 47
a)
Ensure supply voltage is isolated.
b) Drain down the appliance; refer to section 9.24.
c) Disconnect the vent tube from the auto air vent and check that
it is free from blockage.
d) Unscrew the auto air vent, and fit replacement.
e) Re-assemble in reverse order; ensure that all joints and seals
are correctly re-fitted.
f) Open the isolating cocks and vent air from the system using
9.20 AUTO AIR VENT
