GENERAL
These units are controlled by varying water flow through coil.
Follow installation steps in sequence suggested. Each step in-
cludes figure(s) and procedures required for a specific stage
of installation.
Set up a sample installation to familiarize all trades with their
specific job function.
See Fig. 1 for the Proposition 65 warning label. See Fig. 2
and 3 for 36SV,SL base units.

VERTICAL UNIT INSTALLATION
Step 1 — Install Wall Mounting Strip and Hang
Base Unit (see Fig. 4)
1. Determine required length of mounting strip. Allow for
length of enclosures and runouts to be used. Maximum
unsupported length of Carrier enclosures is 2-in. on
either side.
2. Locate strip per job prints. Install straight and level using
field-supplied fasteners through alternate and end holes.
Shim if necessary.
3. Install separate mounting strip above base unit strip for
hanging 36SC or 36ST enclosures if used.
4. Mark enclosure vertical center line on wall near mount-
ing strip.
5. Remove base unit from carton. Retain carton and place
over unit after installation to protect from dirt.
6. Remove unit protective packing.
7. Do not remove lint screen clips (taped to condensate pan)
or tee and connector (tape to side of slave unit) until
required.
8. Install two No. 10-24 bolts (factory-supplied) through
two No. 10-24 speed nuts provided. (These, or any other
suitable means, will be used for unit leveling.)
9. Mark base unit vertical center line on unit.
10. Determine from job prints or certified prints relative
position of base unit with respect to enclosure.
11. Hang base unit on wall-mounting strip, using center lines
for reference.
12. Level unit by adjusting two No. 10-24 bolts (or other
means selected).
Fig. 4 — Hanging Base Unit
Step 2 — Make Air Connections (see Fig. 5)
1. Remove end plug from shipping position. Do not discard.
2. Air connections:
Apply sealer (3M Scotch Seal 800 or equivalent) to end
plug and air transition fitting. Install plug and fitting to
plenum connection. Connect duct to transition fitting;
seal connection with duct sealer. CAUTION: Excessive
duct sealer may interfere with damper movement. After
applying sealer, check damper for free travel by rotating
adjusting screw (See Step 8 — Balance System) with
1/8-in. Allen wrench.
3. Check that all tubing connections are tight.

Step 3 — Connect Piping (see Fig. 6)
1. If coil requires reversing, see Coil Reversal (page 8).
2. Remove burrs and chips from all joints.
3. Locate piping as shown. Piping may run behind 36S
units.
4. Connect water lines to coil. (Bottom coil connection is
recommended for supply.)
5. Use soft or silver solder, if required, for coil connections.
6. Level condensate pan; straighten strap. If drainable con-
densate pan in used, connect to drain line. Pitch drain
line for adequate flow.
7. Insulate water and drain lines if required. Install service
valves between runouts and water control valves.
8. Compress coil end covers slightly and insert between
coil end flanges, with solid (un-notched) side on forward
coil flange. Install coil end covers on 36SV, 36SD only.
9. Install lint screen against coil, securing to flange with
clips provided. Install 2 lint screens on 36ST.
Fig. 6 — Piping Connections
Step 4 — Install Accessory Grilles (If Supplied,
on Furred-In or Custom Enclosure Installa-
tions) (see Fig. 7)
1. Position recirculation grille mounting frame, using holes
provided. Install recirculation grille panel to grille frame.
2. Install discharge grille frame and removable grille sec-
tions. Field-fabricated collar may be installed on front
and sides of unit discharge if required.
Fig. 7 — Accessory Grilles and Field-Supplied
Collar
Step 5 — Install Carrier Enclosures (see Fig. 8)
1. Remove enclosures from carton.
2. On side-fed enclosures, remove end panel knockout as
required for air connections.
36SC,ST unit enclosures (with kickstrip) are for floor-
fed units only; no knockout is provided.
3. Hang enclosure on wall mounting strip. From job prints
or certified prints, determine relative position of enclo-
sure and base unit. Unit discharge must be in line with
enclosure discharge grille.
Hang 36SC,ST enclosures on separate mounting strip
previously installed above base unit strip.
4. Remove front panel. Fasten enclosure to wall, using clips
or tie-down holes. Re-install panel.
Fig. 8 — Enclosure Installation (36SV Side-Fed
Units)
Step 6 — Install Stiffener Brackets for Enclosure
Runouts (see Fig. 9)
1. Determine length of runout from job prints.
2. Place stiffener brackets on wall mounting strip.

Fig. 9 — Positioning Stiffener Brackets
Step 7 — Install Enclosure and Runout
Arrangement As Required
Use end frame as template when drilling holes on unit enclo-
sure side panels. Tap runout enclosure lightly to ensure tight
fit in end frame slots.
COLUMN-TO-COLUMN ARRANGEMENT (SEE FIG. 10)
1. Drill two 3/16-in. holes for attaching runout.
2. Cut runout enclosure and enclosure panel to desired
length.
3. Fit runout enclosure into slots of one end frame.
4. Insert enclosure panel into end frame slots.
5. Fit second end frame to opposite end of assembly.
6. Hang assembly on wall mounting strip and adjacent to
unit enclosure. Stiffener bracket lip must support bottom
of runout.
7. Attach end frame to unit enclosure with two No. 8 sheet
metal screws (field-supplied).
Fig. 10 — Column-to-Column Enclosure Arrangement

5
COLUMN-TO-COLUMN WITH SHELVING (SEE FIG. 11)

length. Maximum unsupported shelf length is 3 ft.
3. Fit runout enclosure into slots of 2 end frames.
4. Install end panels flush with front of runout enclosure,
leaving space at bottom to insert shelving. Fasten end
panels to runout enclosure with U-clips.
5. Insert shelving below end panels, with flanges turned
down. Shelving rests on lower flange of end frame.
6. Hang assembly on wall mounting strip and adjacent to
unit enclosure. Stiffener bracket lip must support bottom
of runout.
