Riser & Cabinet Installation
off the floor while moving cabinet. Look into risers
and remove any debris. From the bottom of the riser,
measure up 2” and mark. See 6B.
3. Raise the cabinet upright, align it and fit 3 risers into
the risers below. The top of each riser is equipped
with a 3" swagged section. Insertion must be 1”
minimum to 2” maximum. Modify risers or use
extensions if needed.
4. Center risers in the slab opening and shim the
cabinet level. Plumb risers in two planes to assure
proper unit operation and condensate drainage.
5. Attach the cabinet assembly to the floor on at least
two sides using sheet metal angles. If risers are
secured to building structure and clamped to cabinet,
mounting angles are not required. A base vibration
dampening pad is recommended to help eliminate
transfer of any vibration to the structure. Material of
0.070 to 0.125 inches thick should be applied to the
perimeter of the cabinet base. Additional anchorage
can be provided by installing brackets at the top of
the cabinet.
6. DO NOT attach drywall studs to cabinet. When all
units on a riser are anchored into place, complete
riser joints as follows:
A. Center the horizontal supply and return runouts
in the expansion slots provided in the back panel
of the cabinet assembly. Assure that runouts are
perpendicular to the back panel.
B. Verify that all riser joints are vertically aligned and
that risers penetrate 1” to 2” into the swaged joint
of the riser below. DO NOT let riser joint bottom
out.
C. Braze riser joints with a high-temperature alloy
(such as Phos-copper or Silfos). Soft solder (50-
50, 60-40 or 85-15) or low-temperature alloys are
NOT suitable for this application.
D. Anchor built-in risers to the building structure
with at least one contact point. To accommodate
vertical expansion and contraction DO NOT
fasten risers rigidly within the unit.
E. Verify that unit shut-off valves are closed. DO
NOT OPEN VALVES until the system has been
cleaned and flushed.
F. Pressure check riser - locate and repair leaks.
G. Check condensate drain - clean pan if needed.
Slowly pour 1 to 2 quarts of water into pan. Water
should drain freely. check for water on floor. Note:
If cabinet is slave, make sure P-Trap Hose is
connected and clamped to master.
H. Repair or replace any damaged or missing
insulation on risers.

To facilitate cleaning and flushing, install the hose
Optional G and H Panel Frame
Position studs in front of cabinet and install frame in
opening. Seal the gap between the cabinet and the
opening. If fresh air motorized damper assembly is used,
field fabricate and install duct from outside to frame
opening. Assembly is installed later. See instructions with
assembly.
NOTICE!
Allow for wallboard thickness under
frame front flange.
Optional Field Supplied Duct Installation
When return air is required to enter the unit through
openings in a stud wall, supply and field install an
optional duct. Seal duct against the return air grille.
Add a blockoff above and below the chassis to ensure
that all air entering the unit passes through the filter
and refrigerant-to-air coil. Sheet metal ductwork must
not be attached to the cabinet. A canvas type flexible
connection should be used between the cabinet and the
ductwork.
When supply air is ducted from unit, sheet metal
ductwork must not be attached to the cabinet. A canvas-
type flexible connection should be used between the
cabinet and the ductwork.
kit at the end farthest from the pump and connect
the ends of the hoses with the riser flush adapter
(Kit - AFL5751). Then open both valves before
pumping fresh water through the system, close the
valves when the system is clean. Remove the flush
adapter before installing the chassis.
NOTE: Refer to System Flushing Section of this
manual for more information.
J. Install vents in piping loop as required to bleed
the system of air accumulated during installation.
Optional factory installed air vents may be
ordered.
Electrical Connections
Complete all electrical connections prior to enclosing
cabinet. See Electrical Section.
CAUTION!
CAUTION! ClimateMaster strongly recommends all piping
connections, both internal and external to the unit, be
pressure tested for leakage by an appropriate method
prior to any finishing of the interior space or before access
to all connections is limited. ClimateMaster will not be
responsible or liable for damages from water leaks due
to inadequate or a lack of pressurized leak testing during
installation.
