ALL ELECTRICAL CONNECTIONS SHOULD BE MADE BY A LICENSED ELECTRICIAN.
NOTE:
The following instructions are intended for Single Phase equipment. If Three Phase equipment was ordered,
refer to the Three Phase Equipment Supplemental Guide at this time.
A Ground Fault Circuit Interrupter (GFCI) is required for this product. A GFCI is a device that shuts off an electrical circuit
when it detects that electricity is flowing along an unintended path. The path could be through a person or water. The
purpose of this device is to reduce the chance of electrical shock. The Hydraulic Power Unit requires one single phase
220v 30amp GFCI protected service.
