ELECTRICAL SAFETY
GROUNDING
This product must be grounded. If it should malfunction or breakdown, grounding provides a path of least
resistance for electric current to reduce the risk of electrical shock. This system is equipped with a cord hav-
ing an equipment-grounding conductor and a grounding plug. The plug must be plugged into an appropriate
outlet that is properly installed and grounded in accordance with all local codes and ordinances.
DANGER – Improper connection of the equipment-grounding conductor can result in a risk of electrocution.
Check with a qualified electrician or service personnel if you are in doubt as to whether the outlet is properly
grounded. Do not modify the plug provided with this system – if it will not fit the outlet, have a proper outlet
installed by a qualified electrician. Do not use any type of adapter with this system.
GROUND FAULT CIRCUIT INTERRUPTER PROTECTION
To comply with the National Electrical Code (NFPA 70) and to provide additional protection from the risk of
electric shock, this system should only be connected to a properly grounded, grounding-type power supply
receptacle that is protected by a Ground Fault Circuit Interrupter (GFCI). Inspect operation of GFCI as per
manufacturers suggested maintenance schedule.
EXTENSION CORDS
If an extension cord is necessary, use only 3-wire extension cords that have 3-prong grounding-type plugs and
3-pole cord connectors that accept the plug from this system. Use only extension cords that are intended for
outdoor use. Use only extension cords having an electrical rating not less than the rating of the system. A
cord rated for less amperes or watts than this system rating may overheat. Exercise caution when arranging
the cord so that it will not be tripped over or pulled. Do not use damaged extension cords. Examine extension
cord before using and replace if damaged. Do not abuse extension cord. Keep extension cord away from heat
and sharp edges. Always disconnect the extension cord from the receptacle before disconnecting this system
from the extension cord. Never yank cord to pull plug from outlet. Always grasp the plug and pull to
disconnect.
