7- Supply Air/Ventilation Motor Fan
The supply air fan motor is mounted with a centrifugal forward curved wheel attached to it. The
access to the motor is on the far-right hand side with respect to the front access panel shown in
photograph 13. Make sure the power is switched off from the GPO before you access the motor.
Remove the panel and access the motor. The motor is mounted with three nuts and bolts on a
bracket fastened on the ring of the inner side panel of the housing. Remove these three bolts and
the ring around it. Remove the opposite side panel to access the wheel attached to the shaft and
undo the grub screw to remove the wheel. If the wheel is fine just replace the new motor using
the same wheel otherwise you can decide to change the wheel also of the same size and part
number, if needed. The access to the motor and wheel is shown through the following photograph
13 and 14. Once you have replaced the motor make sure the wiring is connected as per the
wiring diagram and that the connection to the safety switches in the fan box are not disturbed or
correctly repositioned, and the fan bracket is tightly fastened on the ring and the ring on the
panel.

8. Heat Exchanger
Make sure the heat exchanger is not cracked or blackened, if any abnormality is found on the
tubes of the heat exchanger please ring Eco Pacific on 1300ecopac or 9706 6228. The heat
exchanger is proprietary part that does not normally fail, and if failed, can only be replaced by Eco
Pacific authorised personnel only. This is a major item and is warranted for 10 years, and only
qualified and approved personnel can replace it.
The heat exchanger sits in the middle of the heater and is integrated to the burner facing panel
from the top end to the bottom end and is harnessed onto the base of the heater. This is a
separate assembly that can be procured only from the Eco Pacific factory. If it is found faulty, it
can be removed by undoing the screws on the base, outer lid, inner lid, and burner box. Finally
undo the screws on the base and remove its sealing and take the heat exchanger out. Put the
new heat exchanger of the same model, seal it off on the base and then fasten it with the same
size screws. Fasten with the inner bracket in the lower middle of the tubes on the base, fasten
and seal it off the flue box on to it, and then combustion fan on the flue box. Fasten and seal off
the burner box with gas manifold on the upper section of the heat exchanger, and finally
connecting all the other components and wiring as per instructions, put all the panels back on.
For any parts and their specs please ring Eco Pacific factory on 1300ecopac or 03-9706 6228
