AN INVITATION Please take a few minutes to peruse this instruction manual before using your new oven. We want you to be happy with the equipment, and use it safely. Please be sure that each person who uses the oven reads the instructions. 1.0 RECEIVING AND INSPECTION The carrier, when accepting shipment, also accepts responsibility for safe delivery, and is liable for loss or damage claims. On delivery, you must inspect for visible exterior damage.
Note: 240-volt ovens may be operated on 208-volts. Heat-up will be slightly slower. GROUND YOUR OVEN Our 120-volt ovens are fitted with a power cord having a plug with grounding blade. Be sure the plug is used with a matching receptacle and that the grounding blade is used. DO NOT cut off the grounding blade or plug into a non-grounded receptacle. This would leave the oven's cabinet ungrounded in violation of electrical codes and common sense.
Vacuum Gauge: Measures the vacuum level in the oven form 0 – 30” of vacuum. 6.0 HOW TO RUN THE OVEN The following instructions are for single set point operations only. The Watlow 981 controller has 4 automatic settable profiles with six steps within each profile. For programming and set-up instructions turn to Chapter 7 (page 7.1) in the Watlow manual supplied with your oven.
8.0 TROUBLE-SHOOTING No Heat: 1. The branch circuits serving the oven are dead. 2. Oven cord plug is not in its receptacle. 3. Oven power switch is open (off). 4. The temperature controller is set too low. 5. The overtemperature safety is set too low. It must be higher than the controller. 6.
