SAFETY INSTRUCTIONS
PLEASE READ THIS ENTIRE PAGE BEFORE BEGINNING ANY SERVICE ACTIVITES
This manual is to assist the authorized service agent that has been trained by NEMCO on the proper
service procedures for this appliance.
If at any time the service agent is unsure how to properly or safely service the sandwich press; they should
contact NEMCO immediately for instructions.
All service technicians should check the microwave emission of the appliance using a calibrated
microwave survey meter before they begin any repairs.
The technician should check to make sure the sandwich press isn’t emitting microwaves when it
shouldn’t be.
The control should be checked to see if the control is running a menu cycle.
If it is determined that the service covers are needed to be removed, the oven should be unplugged
from its power receptacle, and the HV capacitors should be discharged using a high voltage insulated
10 MΩ resistor before performing service. Please NOTE: Turning the power switch off will not
completely protect the servicer from electrical shock.
If the microwave circuit must be operated with the service covers removed; DO NOT put any appendage
near any part of the HV circuit. Incidental contact with any part of the HV circuit while the magnetrons
are running WILL result in BODILY HARM or DEATH.
