INSTALLATION

1 Remove the access panel by unscrewing
the 2 x retaining screws, or unlocking the
2 x key operated locks, within the front of
the casing
2 Securely fix the unit to the wall or ceiling
using the four fixing holes on the rear
3 Check whether the water connections are
on the most appropriate side of the unit.
If not, change the 'handing' following the
instructions overleaf
4 Using proprietary fixings, connect the flow
and return pipework to the coil (it is usual
to have the water flow connection on the
air leaving side of the coil), bringing the
pipework in through the holes in the base
of the unit - connections are all sized

Before carrying out any maintenance work it is obviously important to isolate the unit
from the power supply, and to ensure it cannot be accidentally restored by

unauthorised personnel.
The standard cardboard frame panel filter is not designed to be cleaned, and should
be replaced at appropriate intervals, which will vary from site to site.
The coil and fans should be cleaned by vacuuming, again at appropriate intervals.
