INSTALLATION & MAINTENANCE INSTRUCTIONS

MODEL DXP

WARNING! Do not use fans in hazardous environments where the fan’s electrical system could provide ignition to

combustible flammable materials, unless built specifically for that environment. This unit has rotating parts and safety
precautions should be exercised during installation, operation and maintenance.

Remove from shipping crate prior to installation. All debris and shipping material must be removed to prevent obstruction
of airflow to and from the orifice. The orifice opening on both sides must be kept clear of obstructions. Failure to keep
the orifice opening clear could cause undue stresses on the propeller blades, damage to the fan, and unsafe operation
condition.

WARNING! Check voltage being supplied to fan to see that it corresponds with the motor nameplate voltage; high or low voltage can
seriously damage the motor. On multi-voltage motors check motor terminal connections to make sure motor is internally connected for
voltage being supplied. Motor wiring diagram is located on the side of the motor or in the motor wiring compartment. Leave enough
slack in wiring to allow for motor movement when adjusting belt tension.

Fans with elliptical diffusers can be mounted on

67.50 inch centers.

BELT TIGHTENER MAINTANENCE

CAUTION: Before proceeding, make sure electrical service to fan is locked in “OFF” position.

1. If the belt stretches enough that the belt tightener does not keep the belt tight, the belt tightener
can be adjusted. Start by loosening the 3/8 inch bolt holding the belt tightener to the belt tightener
base.

2. Place a wrench on the hex nut in the belt tightener body as shown in Figure 3 and a wrench on
the belt tightener mounting fastener.

3. Using the wrench on the belt tightener body, apply pressure in the appropriate direction (see
Figure 3) until the belt is properly tensioned. Note: The belt tightener body has marks on it as
shown in Figure 4 representing degrees. The proper alignment after tightening the mounting bolt
is shown in Figure 5.

4. With the belt tightener securely held in position, tighten the belt tightener mounting bolt.

INSTALLATION IN WALL

Provide an opening in the wall of the building as shown in Figure 6 using the A
and B dimensions shown in the table below.

A distance of at least four and one-half feet (4 ½’) should be allowed between the
fan inlet or discharge opening and any adjacent wall or large obstruction.

SPECIAL NOTE:

bolts provided by others. Also place lag bolts thru the wall attachment
brackets into the wall to secure the frame assembly to the wall for additional
stability. See Figure 7.

CAUTION! Guards are strongly recommended when the fan is
installed within eight (8) feet of the floor, working level or within
reach of personnel. Guards complying with OSHA regulations are
available as optional equipment. Review OSHA Codes and obtain
a quotation.

Cone Installation

1. Locate the cone mounting brackets as shown in Figure 9.

2. Install the cone mounting brackets on the fan in eight places as shown in Figure 9 using the ¼ x 1 ¼ self drilling
Tek screws provided. Brackets should be mounted at the top, bottom, both sides and next to the joints of the
housing sections as shown in Figure 9.

3. Attach the brackets by placing the base of the bracket against the reinforcing ring around the orifice with the edge
of the bracket against the edge of the reinforcing ring. Using the ¼ x 1 ¼ self drilling Tek screws provided, attach
the bracket to the reinforcing ring.

4. Repeat item three with the next seven brackets.

5. Install the cone over the orifice with the flat sides of the cone parallel with the side of the fan.

6. Using the ¼ x 1 ¼ self drilling Tek screws provided, insert a screw thru the upper hole in one cone mounting
bracket and screw into the cone to hold it in position. Insert a screw thru the lower hole. Continue until all cone
mounting brackets are secured to the cone as shown in Figure 10.

7. Connect the two guard half sections with plastic wire ties spaced evenly along the junction as shown in Figure 11.

8. Slide guard into cone maintaining a vertical placement (as shown in Figure 10) until the eyelets contact the cone
at all points.

9. Mark at least four eyelet positions on the cone. Remove the guard and drill .281 diameter holes at the marked
points.

10. Install the guard by using ¼-20 x 1 stainless steel bolts and nuts provided in the four drilled holes.

11. Drill the remaining eyelet holes and install the ¼-20 x 1 stainless steel bolts in the holes.

MAINTENANCE

1. Motors supplied by Acme have prelubricated bearings.
Consult information printed on motor for lubrication
instructions.

2. Propeller shaft bearings are prelubricated, sealed and
require no service.

3. Check belt tension after first 48 hours of operation and
anually thereafter. Belt should depress its width when
pressed firmly inward at midway point between the
pulleys. Too much tension will damage bearings; belt
should be tight enough to prevent slippage. When
replacing worn belt, replace motor pulley if “shoulder” is
worn in groove.

Warning! Do not operate at higher speeds than rated. Do not
replace motor pulley with a larger diameter pulley. Do not
replace the fan pulley with one smaller in diameter. The
pulley ratios are set so that the motor will not be overloaded.

4. If motor requires replacement, one comparable to the original
with the same service factor and enclosure must be used.

5. If propeller shaft bearings need replacement, replace with

bearings comparable to original equipment. The new
bearings must be installed with neoprene rings. Position
propeller for correct location with orifice, position bearings in
die formed recess and tighten set screws. Replace die
formed bearing cap and tighten four bolts. NOTE: If locking
collar type bearing is used, collar must first be positioned
against inner race on bearing nearest propeller and turned in
direction of propeller rotation with drift pin and hammer until it
locks. Locking collars must be on inbord (facing) sides of the
bearings. Secure bearings to shaft with set screw. Lock and
secure other bearing to shaft in same manner.
