Cleaning and Preventive Maintenance

Oven Weekly Cleaning

In addition to the daily cleaning, it is necessasry to

clean behind the fan guard of this oven on a weekĆ

ly basis. This is necessary for proper functioning

of the oven. Scale will build up on the fan and heat

source leading to a less efficient oven.
1. Turn off the oven. Make sure that the oven is

cooled down to under 140

F (60

C).

2. Remove the rack guides.
3. Rotate the two screws on the left side of the fan

guard.

Figure 14

4. Remove the fan guard.

Figure 15

5. Thoroughly  spray  cleaner  onto  the  fan  and

heat  source.  Close  the  doors  to  allow  the

cleaner to work.

6. After ten minutes, rinse the cleaner off. Return

the fan guard to the closed position. Rotate

the two screws to secure the fan guard.

Remove  and  clean  the  blower  wheel  every  6

months.

CLEANING THE EXTERIOR

The exterior of the appliance may be cleaned and

kept in good condition with a light oil. Saturate a

cloth and wipe the appliance when it is cold; wipe

dry with a clean cloth.

WARNING!!
DO NOT spray the outside of the appliance

with water or clean with a water jet. CleanĆ

ing with a water jet can impregnate chloĆ

rides into the  stainless steel, causing the

onset of corrosion.

PREVENTIVE MAINTENANCE

The  best  preventive  maintenance  measures  are

āāāthe āāāproper āāinitial āāinstallation āāof āāthe equipment and

a  program  for  cleaning  the  appliance  routinely.

The oven requires no lubrication. Contact the facĆ

tory, the factory representative or a local Blodgett

service company to perform maintenance and reĆ

pairs should they be required.
