Electrical Safety
An adequate and safe power supply to the Panel Pit Fan unit is essential for safety. A competent and
qualified electrician must undertake all electrical wiring. All wiring is to be installed according to the
National Standards and Regulations relevant to your Country and Region.
Safety Guards
The Panel Pit Fan contains many moving and electrical parts, which will cause serious injury or death if
touched. Guards are placed on the machine for your protection. Operating the machine at any time with
guards removed or incorrectly fitted is a serious misuse of the machine and endangers safety.
Safety in Handling the Panel Pit Fan
Manual handling of the fans can be a cause of serious injury. Wherever possible, use mechanical lifting
equipment when lifting or moving fans during installation. Where manual handling is required, seek
assistance from other people.
To prevent injury, use suitable hand protection.
Safety in Maintenance
While the Panel Pit Fan is designed to keep maintenance to a minimum, some repairs will be necessary
in the course of the life of the machine. Do not attempt any repairs on the machine unless you are
competent to do so. Remember that the Panel Pit Fan may in cases operate under automatic control and
start without warning. Never attempt any work on the Panel Pit Fan without first isolating the machine from
the mains power, and locking the isolator so that only you can turn the power back ON.
Follow all the guidelines given in the maintenance section on Page 18 of this manual.
Before restarting the Panel Pit Fan, ensure that all electrical enclosures are locked closed and all guards
and other safety measures are correctly fitted.
If in any doubt, contact your dealer or AP/Cumberland for assistance.
General Safety Information
This unit should be assembled and installed by a qualified technician.
Follow all local electrical and safety codes, as well as the National Electrical Code (NEC) and the
Occupational Safety and Health Act (OSHA).

metal-clad raceway system by using a separate ground wire connected to the motor’s ground lug or other
suitable means.
Protect power cable from coming in contact with sharp objects.
Do not kink power cable and never allow cable to come in contact with oil, grease, hot surfaces
or chemicals.
Make certain that the power source conforms to requirements of the equipment.

12° sloped top. (Pump-out lid dimensions are the same for 18" and 24" Panel Pit Fans.)
2. If the pump-out lid is concrete, a frame can be constructed around the opening.
3. Caulk around the base of the pit transition flange and secure to the frame, if needed.

5. Electrical Wiring
All wiring should be installed in accordance with National, State and Local Electrical Codes. A certified
electrician should complete this portion of the installation to ensure safety and that the wiring is correct for
the application.
Fans for use as livestock facility ventilation should be connected to individual electrical circuits, with a
minimum of two (2) circuits per room.
For single phase fans: The motor overload protection should be provided for each fan. A circuit breaker
switch or slow blow motor type fuse must be used.

8. Maintenance
For best results from the equipment, proper inspection and cleaning procedures should be
performed monthly:
1. Inspect the propeller and verify that it is securely located on the motor shaft and that there are no
signs of damage. The blades are self-cleaning and should not require additional maintenance.
2. Clean the following components regularly:
a. Fan motor - Dust with a brush or cloth (DO NOT USE A PRESSURE WASHER). Also, verify that
it is mounted securely.
b. Shutter - Dust the blades and frame with a brush or cloth so that it can open and close freely.
c. Guard - Using a brush, clean dust and debris from the fan guards.
3. Inspect fasteners and tighten loose connections.
4. Check the fan control when the power is disconnected and inspect all electrical connections. Dust
with a brush or cloth. NEVER CLEAN ELECTRICAL EQUIPMENT WITH A POWER WASHER.
Always disconnect and lock out all power sources before performing maintenance.
