Quick Start-Up
Included with each unit (Model 746/747) is a lid strap for user
convenience.
1. Remove the protective white nylon screws from the areas indicated.
Discard these screws.
2. Install the strap as shown below, using the screws included with the
strap.
Warning Use only a grounded electrical receptacle. Failure to ground the
unit can result in serious injury from electrical shock. ▲
With the power switch turned OFF, connect the unit to a grounded
electrical outlet. See the tag on the back of the unit or the electrical
schematics included in this manual for voltage and full load amps.
The power switch on the back of the unit is the mains disconnect and is
also a reset-type circuit breaker. If an overload condition occurs, the built-
in circuit breaker will trip and the power switch will turn off. Turning the
power switch on resets the circuit breaker. If the circuit breaker trips again
within a short time period, the unit should be checked by a qualified
electrician.
