Unit Placement & Assembly
Ensure that the site can support the total weight of the unit.
Unit weight figures only provide total gross weights and do
not include the additional weight for water in any coils.
Confirm that the foundation of the mounting platform is
large enough to include the unit dimensions plus service
access.
The floor or foundation must be level for correct coil
drainage and condensate flow.
Provide adequate lighting for maintenance personnel to
perform maintenance duties.
When the unit is positioned on site,there must be sufficient
space around the unit to ensure that correct operation and
effective maintenance can be carried out. Figure 9 gives
recommended space allowances.
On the designated access side of the unit, working areas
must have minimum 1 mtr, space (P).
Allowance for coil connections, dimension “C” must be
dimension 200mm + unit width.
When selecting and preparing the unit site, follow these
guidelines:

A clear unobstructed area before and after an air intake or
discharge is required to ensure correct air movement. The
width of the area must be >= the width of the unit, and the
depth (dimension “L”) must be >= 0.5 x the overall unit height
