Oven Weekly Cleaning
In addition to the daily cleaning, it is necessasry to clean 
behind the fan guard of this oven on a weekly basis. This 
is necessary for proper functioning of the oven. Scale will 
build up on the fan and heat source leading to a less ef-
cient 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.

4.  Remove the fan guard.

5.  Thoroughly spray cleaner onto the fan and heat 
source. Close the door 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. Cleaning 
with a water jet can impregnate chlorides into 
the stainless steel, causing the onset of corro-
sion.
PREVENTIVE MAINTENANCE
The best preventive maintenance measures are the    
proper      initial      installation      of      the  equipment  and  a 
program for cleaning the appliance routinely. The Hydro-
vection  requires  no  lubrication.  Contact  the  factory,  the 
factory representative or a local Blodgett service com-
pany to perform maintenance and repairs should they be 
required.
