Installing the Fan Unit
(cont)
Horizontal Mounting (Fig. 7)
7. Before installation of the fan unit, a wooden
platform must be provided to mount the unit on.
8. The platform should be constructed from
50mm x 100mm timber bearers with a 19mm
block board deck.
9. The platform should incline the unit to ensure
a fall to the drain outlet. An acoustic mat
(ACMW/HOUSE) can be fitted on top of the
board to minimise vibration.
10. Remove the top cover and withdraw the
heat exchanger from the casing. Carefully drill
four holes through the mounting pads.
11. Secure the casing to the platform deck
using four No.8 round head screws and large
pattern washers to dissipate the load (Fig. 6).
