INStaLLatIoN
Immediately after unpacking the oven, check for possible shipping damage. If the
oven is found to be damaged, save the packaging material and contact the carrier
within 15 days of delivery.
Prior to installation, test the electrical service to make sure that it agrees with the
specificationsꢀonꢀtheꢀmachineꢀdataꢀplateꢀlocatedꢀatꢀtheꢀlowerꢀoutsideꢀcornerꢀofꢀtheꢀ
oven.
LoCatIoN
The oven must be installed on a level surface within 5 feet of both an open drain
and a hot water supply. The installation location must allow adequate clearances
for servicing and for proper operation. Suitable space is needed for the grease
container and the chemical cleaner supply bottle and for access at the doors. for
stackedꢀandꢀcountertopꢀconfigurations,ꢀtheꢀminimumꢀclearanceꢀonꢀtheꢀrightꢀsideꢀ
for plumbing and electrical connections is 3". for out-of-sight, drop-through utility

high-moisture environments such as meat rooms or where high pressure cleaning
is used.
LEGS, CaStErS or StaND aCCESSorIES
A set of four 4" tall legs is available as an accessory. casters are included with the
stacking kit accessory. An oven stand accessory is available; the oven is mounted
on top of the stand.
Tethering is required for units equipped with casters, either on a stand or stacked.

PLaCING tHE rotor IN tHE oVEN
Donotwraptherotororanyotherpartsinsidetheovenwithaluminum
foil. Soft metals can react with oven cleaners, and hazardous interactions can
result.
The rotor must properly engage with the drive mechanism. Orient the rotor so that the
end plate with square drive slots is on the same side of the oven as the drive arm.
STEP 1: Stop the drive arm so it is in the down position (fig. 6).
Fig. 6
STEP 2: Placetherotorshaftontouppernotchof supportbearing
on the non-drive side of the oven (fig.7).
Fig. 7
STEP 3: Place the drive side of the rotor shaft on the drive arm
support notch (fig.8).
Fig. 8
STEP 4: Turn the rotor, lining up the square drive slots on
the rotor end plate with the pins on the drive arm
(fig. 9).
STEP 5: Nudge rotor toward the drive arm. Non-drive end
of rotor shaft falls into the lower portion of support
bearing hub (fig.10). Drive end of rotor shaft is driven
into center hole of drive arm.

Remove all accessories. The rotor can remain. Deliming with vinegar provides a short rinse to clear out
any remaining soapy residue from cleaning or chemical salts. Deliming is recommended once a week,
after an automatic cleaning cycle and after manually wiping out the oven interior (refer to pages 26
through 31).
Do not open doors during deliming.
