Important Installation Considerations

All Milnor/Energenics Lint Collectors can be mounted indoors or outdoors. If it is
mounted outdoors we recommend our Side Discharge or a field installed swept
radius elbow (Gooseneck). Do not use a conical cap on the filter exhaust
discharge. All solenoid valves should be located inside the building. Also, mount
the supplied air pressure gauge at the blowdown pipe on top of the filter.

*NO BIRDSCREENS ON EXHAUST*

All solenoids should be mounted as close to the filter as possible, but ALWAYS
inside the building. This will allow most of the air and water (if equipped with
optional Fire Control) piping to remain pressure charged for most efficient
operation.

All wiring should be a minimum of 18 gauge for proper operation.
The Filter Control box should be located in a position to be easily seen and in

close proximity to personnel. In other words if the Filter Control is located
outdoors, 20 feet in the air or in another room away from the laundry personnel,
this would be the wrong
outdoors.

Since the Filter uses compressed air it is important that the air receiver (if
equipped) be located as close to the filter as possible. The longer the pipe runs
the more restrictive. You will need to increase the pipe diameter if the run is very
long (e.g.: 60 feet).

If the installation is a multi-dryer/multi-duct installation it may be necessary to use
backdraft dampers to prevent lint backflow into the ducts of turned off dryers.
Most dryers have them available as standard equipment or can be ordered to
add on.

After everything is mounted and utilities turned on press the manual blowdown
button located on the bottom of the Filter Control. The rotor on the inside the lint
filter should spin. Make sure that the air pressure at the filter starts out at 100
and ends at about 60 at the end of the blowdown cycle. If it is too low the rotor
won’t turn.

If the Filter is equipped with Fire Suppression, the test button is on the inside of
the Filter Control. It is on the inside to keep people from pushing the button as
they walk by. When the button is pushed the strobe and siren will go on along
with the water solenoid valve. The system operates until the button is no longer
depressed.

location. Lint Filter controls should never be mounted

INSTALLATION OPTIONS

CEILING

SUSPENDED

A

• Allows minimum duct elevation changes, least elbows, and straightest
duct runs.

• Threaded rod suspension.

• Ducting to floor level for lint collection with Energenics flexible connector

to 55 gallon drum.

• Controls mounted on wall or beam at shoulder height.

• 48 inch roof penetration and duct, gooseneck duct on the roof or Optional

Energenics’ supplied side discharge.

• Energenics side discharge available for inside mounting and exhausting
out the side wall.

FLOOR MOUNTED

ON TOWER

B

• Allows minimum duct elevation changes, least elbows, straightest duct
runs.

• Optional Energenics supplied 4 inch tubular tower can be adjusted for
height to match ceiling restrictions.

• All controls should mounted on the tower at shoulder.

• 48 inch roof penetration and exhaust duct.

FLOOR MOUNTED

C

• Requires significant duct elevation changes, thus increasing ducting
backpressure.

• Must be ordered with optional (no cost) legs.

• Can order Pre Plumb option with control mounted on the filter by

Energenics.

• Mounts over 55 gallon drum with Energenics flexible connector.

• Gooseneck duct on the roof or Energenics optional side discharge.

• Energenics side discharge option also available for inside mount and side

wall discharge.

• Gooseneck duct on the roof or Energenics supplied options side
discharge.

ROOF MOUNTED

LINT DROPPED

TO LAUNDRY

FLOOR

D

• Installer must supply roof curb to support the 1,500 lb. filter.

• Guy wires may be required for additional support from high winds.

• Duct to the laundry floor for lint collection in 55 gallon drum with

Energenics supplied flexible connector.

• Controls and air and water valves must be mounted inside. Controls at
shoulder level, valves near the ceiling and roof penetration.

• Energenics optional side discharge or installer supplied gooseneck should
by mounted on the fan discharge and faced away from the prevailing
winds.

ROOF MOUNTED

LINT COLLECTED

UNDER THE FILTER

ON THE ROOF

E

• Least satisfactory method of installing. The 55 gallon drum may fill in 2
hours and must be emptied regularly or the unit clogs and produces high
back pressure.

• Requires installer supplied roof curb and guy wires. The filter with lint
drum underneath stands 30 inches higher than a normal roof mount with
the lint drum inside on the floor.

• Controls and air and water valves must be mounted inside. Controls at
shoulder level, valves near the ceiling and roof penetration.

• Energenics optional side discharge or installer supplied gooseneck should
by mounted on the fan discharge and faced away from the prevailing
winds.
