Cutting out the two slits makes it possible to install as shown in the figure “Field pipes in 4 directions” . (Use a
metal saw to cut out the slits .)
To install the connecting pipe to the unit in a downward direction, make a knock-out hole by penetrating the
centre area around the knock-out hole using a 6mm drill (4x) .
After knocking out the knock-out hole, it is recommended to apply repair paint to the edge and the
surrounding end surfaces to prevent rusting .
When passing electrical wiring through the knock-out holes, remove any burrs from the know-out holes and
wrap the wiring with protective tape to prevent damage .
Preventing foreign objects from entering
Plug the pipe through-holes with putty or insulating material (procured locally) to stop up all gaps, as shown in
the figure .
1 Putty or insulating material (produced locally)
If there is any possibility that small animals enter the system through the knock-out holes, plug the holes with
packing materials (field supplied) .
Insects or samall animals entering the outdoor unit may cause a short circuit in teh electrical box .
Seal knock-out holes to avoid snow and humidity entering .
