PNEG-1756
18" and 24" Panel Pit Fan (78° and 90°)
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
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.
