Cabinet Installation
1. Check plans that cabinet is correct for location,
cabinet will have tag and data plate with information,
including unit size, diameters of risers, and electrical
data.
2. Remove riser KO’s (3) for your cabinet confi guration
(see fi gure 2).
3. Cover supply and return openings with 4 pads. Slit
with knife (see fi gure 7).
4. Slide cabinet up to riser allow 1/4” to 1” (6 to 25mm)
clearance.
5. Attach the cabinet assembly to the fl oor on at least two
sides using sheet metal angles. Additional anchorage
may be provided by installing brackets at the top of the
cabinet.
a. 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.
b. Verify that unit shut-off valves are closed. DO NOT
OPEN VALVES until the system has been cleaned
and fl ushed.
6. For cabinets with chassis inside - remove 4 shipping
screws, discard.
7. Remove inner panel (8 screws), save both.
8. Remove condensate pan shipping wire ties.
9. P-Trap Hose must be connected, lift drain pan, and
clamp to riser stub and pan. If condensate hose must
be rotated, loosen clamp on pan, rotate, and reclamp.
Check condensate drain - clean pan if needed. Slowly
pour 1 to 2 quarts (1 to 2 liters) of water into pan.
Water should drain freely. Check for water in cabinet
and on fl oor. Repair if needed, Retest.
10.Sheet metal ductwork should not be attached to
the cabinet. A canvas-type fl exible connection is
recommended between the cabinet and the ductwork.
11. Optional Electric Heater – Single point power to unit.
Note: Steps 6-10 do after drywall installation.
Optional Frame for G Return Air Panel -
(See recessed
cabinet) Position studs in front of cabinet and install frame
in opening. Seal the gap between the cabinet and the
frame. If fresh air motorized damper assembly is used,
fi eld fabricate and install duct from outside to frame
opening. Assembly is installed later. See instructions with
assembly. NOTICE! Allow for drywall thickness under
frame front fl ange. Must use damper motor assembly if
fresh air is needed.
Optional Field Supplied Return Air Duct Installation
-
When return air is required to enter the unit through
openings in a stud wall, supply and fi eld install an optional
duct. Seal duct against the return air opening with foam.
Ensure that all air entering the unit passes through the
fi lter and refrigerant-to-air coil.
Note: Chassis must be
removable for service.
Drywall Installation
For best sound attenuation, it is recommended not to
attach drywall to cabinet. Install studs and drywall using
conventional construction methods. Secure drywall to
studs with low profi le, pan-head sheet metal screws.
Drywall can be attached directly to cabinet (except in
places indicated in Fig 1), front of cabinet requires double
thickness. Must not be fastened to drain pan edges or
control box enclosure. Do not attach studs to cabinet. Do
not install drywall using adhesive alone.
See typical construction fi gures to determine stud layouts
and dimension from cabinet to fi nished wall.
Vacuum all drywall dust and construction debris from
cabinet insulation, drain pans and blower discharge
plenum after cutting out supply. Insulation should be
placed between the drywall and the cabinet for sound
attenuation.
When drywall installation is complete, cover all cabinet
openings and exposed sheet metal. (Cardboard from unit
shipping cartons can be used). Do not allow paint or wall
texture over-spray to contact insulation, sheet metal, coil,
fan or other unit components. Warranties are void if paint
or other foreign debris is allowed to contaminate internal
unit components.
NOTICE!
NOTICE!
ClimateMaster is not responsible for drywall repair
if 2 x 4 box was not in correct orientation.
