MAINTENANCE SCHEDULE
Every month:
Removeandcleanorreplacelterslocatedoneachsideofcontrolbox.
Every 6 months:
1. Vacuum any lint/dust accumulation around air intake holes on both sides
of oven and on fume hoods.
2. Check tension on the wire conveyor belt and tighten if necessary.
Every Year: (Disconnect power at main panel)
1. Remove top chain guard cover and lightly lubricate the conveyor drive
chain; with SAE 20 weight oil. Replace after lubricating. DO NOT leave
off!
2. Haveaqualiedelectriciancheckallheaterelementstospecications
shown on wiring diagram.
3. Check brushes on conveyor drive motor.
4. Check/tighten all electrical connections on relays and contactor inside
control box.
6. Check thermocouples with ohm meter disconnected from temperature
control. Cold resistance should be between .5 to 2 ohms. Higher resis-
tance readings indicate possible problems with the thermocouple and
in this case it should be replaced.
TO ADJUST THE TENSION OF THE SILICONE RUBBER ON WRAPS:
When the mug wrap is closed around a mug, if the rubber is too loose
or too tight, loosen the two Phillips headed screws and adjust the rub-
ber length to achieve the desired tension. Re-tighten the screws to pro-
vide tension to hold the rubber in the wrap ends. Do not over tighten the
screws, as damage to the silicone rubber can result. (Pic 9)
TO REPLACE THE SILICONE RUBBER ON WRAPS:
If the rubber in the mug wrap has become damaged, or you are replacing
therubberforadifferentsizedmug,loosenthetwoPhillipsheadedscrews
and remove the rubber from the wrap ends. Thread the rubber between
the round bar and wrap itself. Re-tighten the screws to provide tension to
hold the rubber in the wrap ends. Do not over tighten the screws, as dam-
age to the silicone rubber can result.
