1. Certified dimension drawings available on request.2. The minimum required clearance at the back of unit is zero. Clearance above and at right (90MA*8, *12 only) and at left of the 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 Connection”, Condensate drain connections are located on left side of unit for *4 & *6 and on both sides of unit for *08 & *12.

Step 4 - Rig and Place Unit -
NOTE: Install accessories before placing unit.
a. Provide space around unit for service, filter access, andoverhead clearance as indicated in Figure 2.
b. Move and store unit in upright position.c. Use slings with spacer under base skid to prevent panel
damage when using hoist.d. Units as shipped are adequately dampened against
vibration. If additional dampening is desired, placesponge rubber or rubber mat, between deck and base ofunit or install vibration isolators.
e. Unit should be level. Unit leveling tolerance is 1/8 in. perlinear ft in any direction.
Step 5 - Install Accessory Plenum (If Supplied) - Useplenum as template to mark hole locations in top panel. Drill0.154-in. holes in top panel at marked locations and attachplenum with screws supplied.
