Section 2. INSTALLATION – Typical Chassis Unit
IMPORTANT.
PLEASE READ ALL SECTIONS BEFORE PROCEEDING WITH INSTALLATION
STAGES INVOLVED
Figure 8 shows a typical chassis type unit suitable for mounting within a ceiling
void. The following notes give instruction on how the unit is dismantled,
connected to the fresh air, return air and supply air ducts and re-assembled. See
additional sections within the installation instructions for connection to electrical
supply and controls.
Most components used in the manufacture of the chassis unit are the same as
the cased unit. The main exception being that there are no moulded end panels
and that the return air & discharge apertures have fixed spigots (not grilles).
Care should be taken not to damage components and accessories when
handling them.
Before installing the unit check that there will be adequate access space for
maintenance (recommended 300mm each side).
Remember! that in order to get heating on water heated units, all the air must be
bled from the system including the coil in the unit.
