3. Install separate mounting strip above base unit strip for hanging 36SC or 36ST enclosures if used. See Fig. 4.
4. Mark enclosure vertical center line on wall near mounting 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 secondary unit) unti l required.
8. Install two no. 10-24 bolts (factory-supplied) through tw o 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 a wall-mounting strip, using center lines for reference.
12. Level unit by adjusting two no. 10-24 bolts (or other means selected).

Step 2 — Make Air Connections

1. Remove end plug from shipping position. Do not discard. See Fig. 5.
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. See Fig. 5.

CAUTION
Excessive duct sealer may interfere with damper movement. After applying sealer, check damper for free travel by rotatin g adjusting screw (See Step 8 — Balance System on page 7) with 1/8 in. Allen wrench.

3. Check that all tubing connections are tight.

Step 3 — Connect Piping

1. If coil requires reversing see Coil Reversal on page 8.
2. Remove burrs and chips from all joints.
3. Locate piping as shown in Fig. 6. Piping may run behin d 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 condensate 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 coi l end flanges, with solid (unnotched) side on forward coi l 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.

Step 4 — Install Accessory Grilles (if supplied, on furred-in or custom enclosure installations)

1. Position recirculation grille mounting frame, using holes provided. Install recirculation grille panel to grille frame. See Fig. 7.
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.

Step 5 — Install Carrier Enclosures

1. Remove enclosures from carton.
2. On side-fed enclosures, remove end panel knockout as required for air connections (see Fig. 8). 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 o r certified prints, determine relative position of enclosur e and base unit. Unit discharge must be in line with enclo-sure discharge grille. Hang 36SC,ST enclosures on sepa-rate 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.
