PERISTALTIC PUMPS
Disconnect the
electrical power to the machine and
follow lockout / tagout procedures.
Oven cleaners are corrosive and
can cause chemical burns. Rubber gloves, goggles
and protective clothing are required. Read and follow
the instructions for the oven cleaner.
NOTE: Procedure applies to KA7E; and the KA7EM
with grease assist only.
NOTE: KA7E rotisserie ovens previously were
produced with 3 peristaltic pumps - a gray water/sump
pump, grease pump, and chemical pump. The gray
water/sump pump is no longer required in current
production beginning with Serial No. 46300096. The
pump system parameters have changed so that the
main drain pump (not pictured) removes any lingering
gray water from the sump. Refer to
