Explosion Proof Dock Fan/Light Combination

with Adjustable Arm - 24" Fan - 12W LED Lamp

The explosion proof dock fan/light combination unit arrives in several parts for shipping. Follow the steps below
to assemble the unit.

The explosion proof dock fan / light has been disassembled in three parts.

1. Dock Mount Adjustable Arm

2. Explosion Proof Fan / Explosion Proof Camera Assembly

3. Mounting Pole for Explosion Proof Fan

Tools required:

• Drill / Wrench (9/16” & 7/16”)

Additional help for maneuvering unit is also necessary.
All bolting hardware is pre-place on the unit. Remove the bolts / nuts /

washers prior to attaching each part.

1. Locate all pieces shipped with the unit.

(FIGURE A)

2. Install Mounting Pole to Explosion Proof Fan.
a. Locate and remove bolts already attached to base of fan.
b. Place flat side of mounting pole into receiving base of the

fan.

(FIGURE B)

c. Use a 9/16” wrench for the top bolt & 7/16” for the bottom

adjustment bolt.

(FIGURE C)

Note: Adjust fan to the desired angle after installation.

3. Install Dock Mount Adjustable Arm to surface. This can be

installed to the surface before step 4 or after step 5. Note: The fan
and light will add weight to the dock mount.

(FIGURE D)

a. There are six pre-drilled mounting holes available for

mounting dock mount to the surface.

b. Utilize all six mounting holes to secure dock mount to

surface. The explosion proof unit is heavy, therefore; the
surface and hardware used MUST be capable of
supporting the weight.

assembling the unit. Please follow the steps below in order to operate and maintain this product.

IMPORTANT

READ CAREFU LLY BEFORE OPERATING THIS UNIT. SAVE THESE INSTR UCTIONS FOR FUTUR E REFERENCE.
THE EPL-DL-24-12W-WF.24 MUST BE OPERATED IN ACCORDANCE WITH NATIONAL ELECTRICAL CODE AND
ALL APPLICABLE LO C AL CO D ES .

FOR PERSONAL SAFETY, ALWAYS CONFIRM THE RATING OF ANY KNOWN HAZARDOUS OR POTENTIALLY
HAZARDOUS LOCATION WHERE THE UNIT IS TO BE USED.

WARNING: TO PREVENT IGNITION OF A HAZARDOUS ATMOSPHERE, THE SUPPLY CIRCUIT SHOULD BE

DISCONNECTED WHEN INSTALLING OR PERFORMING ANY MAINTENANCE ON THIS UNIT.

WARNING: W HEN INSTALLING UNIT IN HAZARDOUS LO CATIONS, CHECK THE OPER ATING TEMPERATURE

LIMITS PRIOR TO INSTALLATION TO BE SURE IT CONFIRMS TO THE ENVIRONMENTAL TEMPERATURE
RESTRICTIONS AND NEC CLASSIFICATIONS. CHECK THE NAMEPLATE FOR TEMPERATURE (T) RATINGS.

WARNING: TO REDUCE THE RISK OF FIRE OR ELECTRIC SHOCK DO NOT USE ANY SOLID-STATE SPEED

CONTROL DEVICE WITH THESE FANS.

WARNING: OPERATE FAN / LIGHT ONLY AT THE VOLTAGE OF YOUR SPECIFIC SU PPL Y CIRCUIT.
WARNING: SUBSTITUTE COMPONENTS MAY IMPAIR EXPLOSION PROOF SAFETY.
WARNING: BEFORE SERVICING O R CLEANING THE UNI T, SWITCH THE POWER OFF AT THE SERVIC E PANEL

AND LOCK SERVICE PANEL TO PREVENT POWER FROM BEING SWITCHED ON ACCIDENTALLY.

• USING THIS PRODUCT FOR ANY OTHER PURPOSE THAN IT WAS INTENDED, OR NOT WITHIN THE
OPERATING SP ECIFICATIO NS IN THIS MANU AL W ILL VOID THE WARRANTY AND MAY C AUSE DAM AGE TO
THE FAN / LIGHT OR SERIOUS INJURY TO PERSONNEL.

• DO NOT EXPOSE FAN TO WATER OR RAIN.

OPERATION

Plan a way for mounting the dock light / fan. Place in a location where it can operate as intended. Ensure the
surface and hardware used are capable of supporting the weight. Ensure the fan will not come into contact
with water.

WIRING

CAUTION:
ALL ELECTRICAL WORK SHOULD BE PERFORMED BY A QUALIFIED ELECTRICIAN AND MEET ALL
NATIO NAL, STATE, AND LOCAL CODES.

Be sure the voltage and cycles shown on the motor nameplate correspond to the power supply. Check product
nameplate for Ratings and Approvals. This fan / ligh t is rated for single phase 115V or 230V AC 60 Hz
operations based on model purchased. CHECK VOLTAGE RATING PRIOR TO ENERGIZING.

Units pre-wired with 120V 3-prong power cord:

• The power source must conform to the electrical requirements of the fan / light.

• The power cord has a 3-prong grounded plug that must be plugged into a compatible circuit.

• Do not alter the plug to remove the grounding prong and never use a two prong adapter.

• Replace damaged or worn power cords immediately.

• Where possible, avoid using extension cords. If one must be used, the cord must be UL listed, be the

proper size (Amp rating), and have 3-prong grounded connections.

Before activating unit, inspect to be sure that there are no obstructions or debris on the fan that would interfere
with the propeller. Check all fasteners for tightness.

LAMP

Use single bolt to provide rotation when mounting. Loosen the two set screws on the bracket to adjust vertical
position as necessary. Lamp is “instant-on” and will illuminate once power is supplied.

RECEPTAC L E OPERATION

Electrical connection between explosion proof receptacles and plug is accomplished after plug fully inserts into
receptacle and rotated clockwise.

1. Lift receptacle door and locate polarization on mating plug pin and receptacle face. Insert plug straight all
the way into receptacle until it cannot go further.

2. Rotate plug clockwise limit (37º), this closes internal contacts and completes circuit. This also mechanically
locks plug into receptacle so it cannot be pulled out.

3. To remove plug, push plug inward and turn to counterclockwise, pull plug straight out.

REMOVE MOTOR DRAIN PLUGS

• After installing the fan, remove the motor drain plug located at the lowest
point of the motor.

• Failure to remove the drain plug may allow condensation to build up
inside the motor, reducing motor life and will void the warranty.

• Do not remove drain plugs on the top side of the motor.

• Drain plug locations and quantity may vary by motor design.

TILT ADJUSTMENT

The fan can tilt up or down by loosening the fasteners on the motor yoke
bracket. Loosen the center 3/8” bolt and 1/4” bolt to adjust the fan to the
desired angle and securely tighten all mounting hardware.

CAUTION: Fasteners m ay loosen over time. It is
important to check and tighten f as teners frequently.

MAINTENANCE

WARNING:

DISCONNECT POWER BEFORE CLEANING OR MAINTAINING YOUR UNIT IN ORDER TO PREVENT
SERIOUS INJURY OR DEATH.

It is recommended that you implement a standard monthly or more frequent preventive maintenance schedule.
Safety requires a thorough visual examination of the unit for physical damage that might cause a spark or
result in the ignition of hazardous atmospheres.

Maintenance includes a careful examination to ensure at least:

A. The Cable is not frayed and is gripping tightly in all points of cable contact.
B. The Cable Jacket is completely intact and that no internal conductors or conductor insulation

is exposed.

C. The Connection Box is not cracked, broken or breeched.
D. The Cord Plug is not cracked or damaged and the Ground Post is intact.

Keeping blades clean and free of material splatter, overspray, and debris during usage will ensure the
maximum life of the fan. An accumulation of dirt may cause blade vibration and motor overload. Occasionally
check tightness of blade set screws.

NOTE: Handle the propeller carefully as it is factory balanced and aligned to ensure smooth operation.

• Some maintenance procedures may require removal of fan guarding.

• After servicing, guards and other safety devices must be reinstalled per their original condition.

• Excessive dust and debris may cause overheating and reduced fan performance.

• Keep guards, motor and blades clean by vacuuming or wiping with a damp cloth.

• Do not use harsh chemicals or cleaners to clean any part of the fan.

• Pressure washing the unit will void the warranty.

• Sealed motor bearings are pre-lubricated and do not require servicing.

LAM P MAINTENANCE

• The lens should be cleaned periodically to ensure continued lighting performance. To clean, wipe the lens
with a clean, damp cloth. If this is not sufficient, use a mild soap or a liquid cleaner such as Collinite NCF or
Duco #7. Do not use an abrasive, strong alkaline or acid cleaner. Damage may result.

• Visually check for undue heating evidenced by discoloration of wires or other components, damaged parts,
or leakage evidenced by water or corrosion in the interior. Replace all worn, damaged, or malfunctioning
components, and clean gasket seals before putting the luminaire back into service.

• Electrically check to make sure that all connections are clean and tight.

• Mechanically check that all parts are properly assembled.
