service, the Yazaki chiller-heater will not perform correctly on a continuous basis
without proper maintenance. Furthermore, always avoid placing the cooling tower at a
lower level than the chiller-heater. Such designs invariably lead to problems with
maintaining pumping stability.
3.2 Minimum Maintenance Clearances
The minimum space and
clearance
requirements
shown in figure 3 must be
provided
around
each
chiller-heater
unit
to
facilitate
installation,
commissioning
and
procedures in maintenance.
The clearances shown in the
table below apply to the CH-
K 30 through to the CH-
K100 machines.
If the
system is a multi-module
configuration where chiller-
heaters will be placed side-
by-side,
the
clearances
recommended
must
still
apply. If the recommended
service clearances cannot be
provided as indicated, the
chiller-heater should not be
installed.

3.3 Foundation
Mount the absorption chiller-heater on a level foundation constructed of non-
combustible materials, capable of supporting the operating weight of the machinery.
This particularly applies to roofs, if that is where installation is contemplated.
Be sure the roof is able to support the chiller-heater, cooling tower, pumps and
associated piping (refer Section
1. Specifications
for details). It is additionally
important that, if the equipment is to be placed on the roof of a building, it should be
located in a well drained area and at least two meters from the edge. A suitable
