Section 2 Installation Instructions

Electrical Service

!Warning

All wiring must conform to local, state and national codes.

VOLTAGE

The maximum allowable voltage variation is ±10% of the rated voltage at ice machine start-up (when the electrical load is highest).

!Warning

The ice machine must be grounded in accordance with national and local electrical codes.

All electrical work, including wire routing and grounding, must conform to local, state and national electrical codes. The following precautions must be observed:

•The ice machine must be grounded.

•A separate fuse/circuit breaker must be provided for each ice machine.

•A qualified electrician must determine proper wire size dependent upon location, materials used and length of run (minimum circuit ampacity can be used to help select the wire size).

•The maximum allowable voltage variation is +/-10 of the rated voltage at ice machine start-up (when the electrical load is highest).

•Check all ground screws in the control box and verify they are tight before starting the ice machine.

Important

Observe correct polarity of incoming line voltage. Incorrect polarity can lead to erratic ice machine operation.

FUSE/CIRCUIT BREAKER

A dedicated circuit and a separate fuse/circuit breaker are required for each ice machine.

GROUND FAULT CIRCUIT INTERRUPTER

We do not recommend the use of a GFCI/GFI circuit protection with our equipment. If a GFCI/GFI is required by code, use a GFCI/GFI breaker rather than outlet which is more prone to intermittent nuisance trips than panel circuit breakers.

MINIMUM POWER CORD SPECIFICATIONS

The wire size to the receptacle is dependent upon location, materials used, length of run, etc., so it must be determined by a qualified electrician. Local, state or national requirements will supersede our minimum requirements.

FOR UNITED KINGDOM ONLY

As the colors of the wires in the mains lead of the appliance may not correspond with the colored markings identifying the terminals in your plug, proceed as follows:

•The wire which is colored green and yellow must be connected to the terminal in the plug which is marked with the letter E or by the earth

ground symbol or colored green or green and yellow.

•The wire colored blue must be connected to the terminal which is marked with the letter N or colored black.

•The wire colored brown must be connected to the terminal which is marked with the letter L or colored red.
