F90A,B
CAUTION
Do not connect the power supply until F90 is mounted. If the F90 is powered before an electrical check, be extremely careful to avoid electrical shock. Also, take care when working near the F90 moving parts.
Unpacking
1.All F90 components are packed in one box. Slide the F90 out of the box and remove all packaging material.
•Carefully check all F90 components when unpacking.
•Check all packaging materials before discarding to assure no parts or papers are lost.
•Use the mounting template marked on the outside of the box for easy installation.
2.Pull the two latches located on the front of the F90 cover. Swing the cover down and lift to disengage from the hinges.
3.Remove the prefilter and cell from the channel guides.
4.If installing the optional WASH LED, remove the power supply switch plate. To install the WASH LED,
see Fig. 6.
5.Remove the power box from the unit. See Electrical Troubleshooting section for instructions.
Mounting
WARNING
Heavy Equipment.
Can cause personal injury or equipment damage.
1. If the ceiling is not reinforced properly, the weight of the F90 could cause structural weakening and buckling. The unit can fall, presenting a danger to persons and equipment.
2. When using the keyhole slots for mounting, assure the washer diameter is larger than the keyhole diameter (3/4 in. [19 mm]) or assure the mounting screws are secured in the small keyhole slot.
IMPORTANT
1. When mounting near walls, allow at least 16 in. (406 mm) for cell installation and removal and 15 in. (381 mm) for cover installation and removal. See Fig. 7.
2. Select a structurally strong part of the ceiling or wall for mounting. Do not mount the F90 to a suspended ceiling, to plaster, or to wallboard. If necessary, construct strong framing to support the weight of the F90.
The F90 can be mounted in any of four ways:
• Mounted into a ceiling joist using lag screws. See Fig. 8.
• Mounted into a suspended ceiling using threaded steel rods. See Fig. 9.
• Mounted into a ceiling joist or suspended ceiling using a transition plate accessory. See Figs. 10 and 11.
• Mounted into a wall using the wall mounting hardware accessory. See Fig. 12.
The F90 may also be mounted with lag bolts or threaded steel rods reaching down to the venturi plate. However, ensure the bolts or rods are short enough to avoid interfering with the cells. Assure
For F90 installation dimensions, see Fig. 7.
Mounting the F90 Using Lag Screws
1.Locate the ceiling joists. See Fig. 8.
2.Drill four 5/16 in. (8 mm) pilot holes in the joists using the mounting template to locate holes.
3.Lift the F90 to the mounting location.
4.Mount the F90 using four 3/8 in. x 3 in. (10 mm x 76 mm) lag screws and washers.
NOTE: Assure the washer size is larger than the 3/4 in. (19 mm) diameter of the keyhole or assure the mounting screws are secured in the small keyhole slot.
