6. Connecting condensation drain
The condensation drain must be mounted at the bottom of the HR heat recovery unit with the fitting supplied. Use a
20mm hole saw to cut the hole, take care to cut on the correct side of the unit according to left or right handed
configuration. Use silicon sealant to seal the condensation fitting to the HR unit.
The drain must discharge into the household drainage system and must be insulated.
Follow the steps below:-
1. Lay the unit on a flat level surface
[1]
and carefully slide the heat recovery cell out from the
housing
[2]
put the cell to one side.
2.
Determine what side you want the condensate drain to be (see page 8 for left and right hand positioning), if
mounting the unit vertically the condensate hole needs to be in position shown at its lowest point to allow the
condensate to run out
[3]
(image shown for right hand installation).
3. If mounting the unit horizontally then position the condensate hole in position shown
[4]
(image shown for right
hand installation).
4. Use a 20mm hole saw to cut-out the correct bung, Clean away any debris from drilling the hole.
5. Screw the condensation fitting as shown
[5]
and silicone seal to create a water tight seal.
6. Connect up to the household drainage system.
7. Ensure that the drain incorporates a U-bend to prevent air penetration.
8. Ensure that the distance between the unit and the U-bend is adequate for de-mounting and cleaning if required.
