Basic Troubleshooting - Metro DataVac C5 6 series Instructions For Use Manual

BASIC TROUBLESHOOTING

1. Controls do not work (indicator lights):
a. Check that the cabinet is plugged in.
b. Check that the outlet has power.
c. Check that the power switch is in the "On" position.
d. Check the cabinet wiring from the power cord to the power switch and to the terminal block.
2. Temperature too hot:
a. Temperature set point is too high. Turn control knob down to a lower setting.
b. If displayed temperature exceeds 220°F (104°C):
i. Blower wiring is faulty or disconnected.
ii. Blower needs replacing.
iii. The thermostat may have failed and the thermal overload device is controlling the temperature. Stop using
the cabinet immediately and contact a factory approved service agent.
3. Temperature too low:
a. The cabinet may still be in pre-heat or recovering from a door being opened.
b. Temperature set point is too low. Turn temperature control knob to a higher setting.
c. A door is not closed or sealing properly.
d. Blower is not circulating air:
i. Blower wiring is faulty or disconnected.
ii. Blower needs replacing.
4. No heat generated
a. If the heat indicator light is on but the cabinet does not draw approximately 16 amps for 120V 2000W units;
12 amps for 120V 1440W units; or 8 or 9 amps for 220-240V units:
i. Air heater element may be faulty.
ii. The wiring to the air heater element may be faulty or disconnected.
iii. The thermostat may be faulty.
5. Cabinet trips GFCI (ground fault circuit interrupter):
A GFCI receptacle protects against "ground faults" whenever an electrical product is plugged into the GFCI
outlet by constantly monitoring the electricity for any loss of current. If the current flowing out of the receptacle
differs by a small amount from that returning, the GFCI quickly switches off power to that circuit. The GFCI
interrupts power extremely fast to minimize the possibility of an electric shock.
a. The heater element may absorb some moisture into its casing and insulation during shipment or during long
periods of not being used (such as during the summer in a closed school kitchen). Plug the cabinet (without
water in the water pan) into a non-GFCI outlet, set the temperature to "10" and let it run for 30-60 minutes
to dry out any moisture the element may have absorbed. (If it trips the standard circuit breaker call factory
approved service agent.) After drying the element, plug the cabinet into the GFCI outlet; the cabinet shoul d
run without tripping the GFCI.
b. If the cabinet still trips the GFCI, call a factory approved service agent.
Warning: Only factory approved service agents should attempt
to service, repair or replace electrical components,
wiring or power cord.
