INTRODUCTION

This commercial countertop Marinator Model

MDMW-10 is designed to hold food at desired

serving temperature. For the best results, the

MDMW-10 Marinator must be operated with water in

the pan as described in the operating procedure.

Wet operation distributes heat evenly to the food

which is placed in the 3 pans provided.

NOTE: While unit is in operation, all 3 pans must

stay in unit even if pans are empty to ensure

temperature integrity of products.

Knowledge of proper installation, operation and

maintenance procedures is essential to ensure

safe operation of any equipment. The following

guidelines should be kept in mind:

1. Use dry hands to turn power switch ON or OFF.

2. Turn OFF power switch when the marina-tor is

not in use.

3. If an electric shock is felt when touching the

marinator, disconnect immediately. Call Wells'

Service Department for assistance and service.

4. Have electrical supply outlet installed by a

licensed electrician. Insure that equipment is

properly grounded.

5. If you find that the electrical cord is frayed, DO

NOT PLUG IT INTO A POWER RECEPTACLE.

If already plugged in, disconnect the plug after

shutting OFF the circuit breaker.

6. Disconnect the power cord before attempting

any repairs and/or cleaning of the unit.

7. Allow unit to cool before cleaning.

8. Do not splash water onto the unit. Wet elec-

trical components and wiring present a high

shock hazard.

9. Do not remove scale build-up from pan with a

sharp knife — follow cleaning procedure

described on the MRC 61.
