INSTALLATION

Step 1 — Place Units in Position

42C UNITS

1.Select the unit location. Allow adequate space for free air circulation, service clearances, piping and electrical connections, and any necessary ductwork. For specific unit dimensions, refer to Fig. 1-14. Allow clearances ac- cording to local and national electric codes.

2.Make sure ceiling is able to support the weight of the unit. See Table 1 for nominal unit weight.

3.Ensure bottom panel has been removed from 42CG, CK units with mounting holes. When unit is lifted, access to the 0.375-in. mounting holes is through the bottom of the unit. Hanger rods and fasteners and other required hard- ware must be field-supplied.

4.Move unit into position. Ensure unit is level or pitched towards drain to ensure proper drainage and operation. Pitch of suspended unit can change after coil is filled; recheck after filling coil.

5.Mounting unit:

a.Use rods and fasteners to suspend the unit at the factory-provided mounting holes with rubber grommets on the top of the unit on 42CG, CK units. Reach into unit and attach unit to the ceiling using the 0.375-in. mounting holes (4) in top panel; do not use any other locations.

b.Use rods and fasteners to suspend the unit at the factory-provided 0.375-in. hanger slots (4) with rubber grommets on the top of the unit on the 42CA, CE, and CF units.

NOTE: The four mounting holes and hanger slots with rubber grommets are NOT for balancing unit.

6.42CA and 42CF units without plenums and 42CE and CF with bottom inlet may be installed in noncombustible areas only.

NOTE: The installation of horizontal concealed units must meet the requirements of the National Fire Protection Associa- tion (NFPA) Standard 90A or 90B concerning the use of con- cealed ceiling space as return-air plenums.

42V UNITS

1.Select the unit location. Allow adequate space for free air circulation, service clearances, piping and electrical connections, and any necessary ductwork. For specific unit dimensions, refer to the submittals. Allow clearances according to local and national electric codes.

2.Make sure the floor is able to support the weight of the unit. See Table 2 for nominal unit weight.

3.Ensure wall behind unit is smooth and plumb; if necessary, install furring strips on walls with irregular surfaces or mullions. Furring strips must be positioned behind mounting holes in unit (42VA, VB, VF units). Fasteners, furring strips, and other seals (if required) must be field-supplied.

4.Remove all wall and floor moldings from behind the unit.

5.Ensure 42VA top panel (under window application) and 42VB, VF front panel has been removed from unit to obtain access to the four 0.75-in. mounting holes. Hanger rods and fasteners and other required hardware must be field-supplied.

6.Move unit into position. Ensure unit is level or pitched towards drain to ensure proper drainage and operation. Pitch of suspended unit can change after coil is filled; recheck after filling coil.

7.Adjust 42VA, VB, VC, VE, VF units leveling legs so unit is level. Unit must be level for proper operation and condensate drainage.

8.Mounting unit:

a.Use rods and fasteners to suspend the unit at the factory-provided mounting holes with rubber grommets on the top of the unit on 42VA, VB, VF units. Reach into unit and attach unit to the wall using the 0.375-in. mounting holes (4) in top panel; do not use any other locations. The four mounting holes and hanger slots with rubber grommets are NOT for balancing unit.

b.On 42VG unit ensure unit is placed snug within the wall.

c.On 42VC, VE unit ensure unit is flushed against the wall.

NOTE: For any unit without a return-air duct connection, applicable installation codes may limit unit to installation in single story residence only.

42D UNITS

1.Select the unit location. Allow adequate space for free air circulation, service clearances, piping and electrical con- nections, and any necessary ductwork. For specific unit dimensions, refer to the submittal drawings. Allow clear- ances according to the local and national electrical codes.

2.Be sure either the ceiling (42DA, DC, DE, and DF units) or floor (42DD unit) is able to support the weight of the unit. See Table 3 for nominal unit weight.

3.Move unit into position. Ensure unit is level or pitched towards drain to ensure proper drainage and operation. See Fig. 23-27. Pitch of suspended unit can change after coil is filled; recheck after filling coil.

4.Mounting units to the ceiling:

a.When unit is lifted, access to the 0.375-in. mount- ing holes is on the top panel of the unit. Hanger rods and fasteners and other required hardware must be field-supplied.

b.Use rods and fasteners to suspend the unit at the factory-provided mounting holes with rubber grommets on the top of the unit. Attach unit to the ceiling using the 0.375-in mounting holes (4) in top panel; do not use any other locations.

c.Use the rods and fasteners to suspend the unit at the factory-provided 0.375-in. hanger slots (4) with the rubber grommets on the top of the unit on the 42DA, DC, DE, and DF units.

NOTE: The four mounting holes and hanger slots with rubber grommets are NOT for balancing unit.

d.Models 42DA and 42DC with bottom inlet may be installed in noncombustible return spaces only.

5.Mounting units on the floor:

a.Ensure wall behind the unit is smooth and plumb; if necessary, install furring strips on walls with irregular surfaces or mullions. Furring strips must be positioned behind mounting holes on 42DD units. Fasteners, furring strips, and other seals (if required) must be field-supplied.

b.If the unit has leveling legs, adjust them correctly to level the unit.

6.Protect units from damage caused by jobsite debris. Do not allow foreign material to fall in unit drain pan. Prevent dust and debris from being deposited on motor or fan wheels.
