MAINTENANCE & CLEANING GUIDE

MAINTENANCE
NU-VU® equipment is designed to last for years of useful service. Careful consideraon is given in selecng
components for durability, performance and ease of maintenance. For example, both the oven motor and
proofer motor have sealed bearings and never need to be lubricated.
While NU-VU® equipment is designed for minimum care and maintenance; certain steps are required by the
user for maximum equipment life and eecveness:
Proper installaon of the equipment.
Correct applicaon and usage of the equipment.
Dry-out Procedures performed daily.
Thorough cleaning on a regular basis.
AUTOFILL Proofer Dry-Out Procedure
It is recommended that the dry-out procedure be performed any me the proofer will be o for more than a
few hours.
A. Wipe out any standing water in the boom of the Proofer.
B. Empty, clean, and replace the Drain Pan beneath the Proofer.
C. Set the Proofer Power Switch to ON. Leave the Temperature Control at its normal seng. Turn the
Humidity dial to the OFF seng.
D. Leave the Proofer Door open by about 1 to 2 inches and allow the Proofer to run for about 20 to 30
minutes or unl it is dried out.
E. Set the Proofer Power Switch to OFF. Leave the Proofer Door slightly open (about 1 to 2 inches)
while the Proofer is not in use.
Oven Dry-Out Procedure
A. Set the Oven Power Switch to OFF.
B. Leave the oven door open about 1 to 2 inches. The residual baking heat will dry out any moisture
that may be trapped in the insulaon or other components of the oven.
Leave the oven door slightly open (about 1 to 2 inches) while the oven is not in use.
IMPORTANT: THESE DRY-OUT PROCEDURES MUST BE CARRIED OUT DAILY TO HELP
MAINTAIN YOUR EQUIPMENT IN THE BEST POSSIBLE CONDITION. THE REMOVAL OF RE-
SIDUAL MOISTURE HELPS PREVENT DETERIORATION OF THE INSULATION, DAMAGE TO
THE PROOFER ELEMENTS, SENSORS, MOTOR AND OTHER ELECTRICAL COMPONENTS,
AND EXTENDS THE USEFUL LIFETIME OF YOUR NU-VU® EQUIPMENT!

CLEANING
Your QB-5/10 should be cleaned daily and as soon as possible aer a spill has occurred. It is essenal to maintain a clean unit,
especially if the public views the unit in your place of business. The following should be used for cleaning:
A. The stainless steel exterior may be cleaned with any good stainless steel cleaner or polish, or with hot soapy water
followed by a clear rinse if it is very soiled.
B. All glass should be cleaned with a glass-cleaning formula. Baked-on or excessive soiling can be removed with soap and
hot water followed by a thorough rinse with fresh clean water.
C. The oven and proofer interiors should be cleaned on a regular basis with mild soap and hot water followed by a
thorough rinse with fresh clean water.
D. Proofers equipped with AUTOFILL opon should have the water pan inspected and cleaned at regular intervals as de-
termined by usage and water hardness. To clean the water pan:
1. Ensure that the Proofer is OFF prior to cleaning the water pan.
2. Open proofer door, li the right sidewall approximately 1/2" and swing towards the center of cavity to access the
element cover and water pan.
3. Clean scale build up from water pan and element with approved cleaner and rinse.
4. Swing right ladder back, li approximately 1/2" and hook on studs.
To prevent problems caused by accumulaon of lime and mineral, clean the water pan every week.
* * * CAUTION * * *
NU-VU® DOES NOT RECOMMEND the use of any strong commercial or causc product on this equipment. DO NOT allow any type
of causc cleaner to come into contact with any aluminum parts (such as door frames), the silicon rubber door gaskets, or any of
the sealing compound in the oven and proofer seams and joints. These compounds may cause discoloraon and degradaon of
these parts resulng in permanent damage. DO NOT use bleach or bleach compounds on any chromed parts; bleach will damage
chrome plang. DO NOT CLEAN THIS APPLIANCE WITH A WATER JET OR PRESSURE WASHER.
NOTE:
NU-VU® has had very good results with a product called JIFFY CLEANER. For standard cleaning simply spray JIFFY on and wipe o.
Heavily soiled areas may require a short period of soaking. This cleaner is available through NU-VU® (Part #51-0002) or through
your local Rochester/Midland distributor or representave.
WARNING: Do not use oven cleaners in the oven!
Once in the side walls these cleaners are very dicult to remove, and may cause your oven to
smoke or emit noxious fumes unl they are rinsed out or burned away. You will need to com-
pletely disassemble the oven interior in order to ush out any remaining oven cleaner.
