Supply and Return Stack
1.
Install a drain valve, shut-off/balancing valves, flow
indicators and drain tees at the base of each supply
and return riser stack to enable system flushing at
start-up, balancing and during servicing.
2. Install strainers at the inlet of each circulating pump.
3. Insulate loop water piping which runs through non-
conditioned areas or outside the building. For boiler
tower applications loop temperature is normally
between 60°F and 90°F, piping does not sweat
or suffer heat loss under ambient conditions. For
geothermal applications insulate all loop water piping.
4.
Cabinet slots and riser stack assemblies are designed
to accommodate a maximum of 1-½”(38) expansion
and 1-½”(38) contraction. If the calculated riser stack
expansion or contraction exceeds 1-½”(38), expansion
devices must be provided.
Condensate Piping -
Standard and Leader Cabinets (risers
shipped attached to the cabinet) - Condensate connection
between the drain pan assembly and condensate riser is
factory installed, clamped, and trapped in cabinet. Follower
cabinets (risers shipped loose or field provided) installer
must clip and remove 2 drain pan shipping ties, lift drain pan,
extend drain riser stub into cabinet, measure and cut drain
hose to length, connect rubber p-trap to riser and clamp.
⚠
NOTICE!
⚠
Loose risers with brazed shutoff! Make sure shutoff handles
are parallel with riser entry side of cabinet before brazing
stack.
Optional Frame for Return Air G Panel -
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, field 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 flange.

⚠
NOTICE!
ClimateMaster is not responsible for wallboard
repair if 2 x 4 box was not in correct orientation.
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.
Drywall Installation -
If you have the surface mounted
thermostat option (cabinet model digit 5 = P, S, or 5), make
sure before you install the drywall that the 2x4 junction
box is in the correct orientation. Turn if needed. Check your
thermostat.

For best sound attenuation, Do not to attach studs or
drywall to cabinet.
Install studs and drywall using conventional construction
methods. Secure drywall to studs with low profile, pan-
head sheet metal screws. Drywall must not be fastened to
drain pan edges or control box enclosure. Drywall can be
attached directly to cabinet (except in places indicated in
Figure 1), front of cabinet requires double thickness. Do not
attach drywall studs to cabinet. Do not install drywall using
adhesive alone.
See typical construction figures 4, 5, and 11 to determine
stud layouts and dimension from cabinet to finished wall.
Vacuum all drywall dust and construction debris from
cabinet insulation, drain pans and blower discharge
plenum after cutting out supply and return holes for grilles.
Insulation should be placed between the drywall and the
cabinet for sound attenuation.
When 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.
Do not adjust the Sight and Sound X-baffle (see Figure 7).
It is not designed to be used as a damper.
