NOTES:

1.Certified dimension drawings available upon request

2.Minimum required clearance at back of unit is zero. Clearance above and at right (90MA008,012 only) and at left of

unit depends on space required for accessory plenum, ductwork, condenser piping, accessory heater piping, condensate drain line and power wiring

3.Water connections are located on left side of unit (Refer to “Make Condenser Connections”, Condensate drain connections are located on left side of unit for 004 & 006, and on both sides of unit for 008 & 012.

Figure 2 Unit Dimensions

b.Attach a one-inch (2.5 cm) flange or attach a flanged, flexible duct connection directly to unit.

If an outdoor makeup air damper is to be installed, at- tach it directly to unit back panel and install flexible connection between damper and remaining duct- work. Use accepted ductwork installation proce- dures. Follow all applicable codes.

c.Completely blank off the standard return-air opening with a field-fabricated filler panel. The panel must be removable for service access. Refer to paragraph 5.1.

3.9Check Return--Air Filters

Ensure filters shipped with unit are in place. Never operate unit without return air filters in place.

3.10Align Fan Shaft and Wheel

HORIZONTAL WHEEL CENTERING --All wheels must be

horizontally centered between the inside edges of their fan scroll ventures (Figure 3). Adjust as follows:

a. Loosen set screws holding wheel to shaft. b. Center the wheel by sliding it horizontally. c. Re-tighten set screws.

CONCENTRIC ALIGNMENT --Shaft and wheels must be concentrically centered with the venturi (Figure 4). Shaft bearings are supported by bearing supports. If shaft and wheels are concentrically misaligned from shipping shock, it is possible to re-bend bearing support arms to original positions. Replace the bearing support if it has been extensively damaged during shipping.

DIMENSION “D” MUST BE EQUAL ALL AROUND
