EXTERNAL STEAM OPTION:
This option uses a 60–Minute Steam Timer to operate and control a separate external Steam
Generator. The separate Steam Generator contains its own heat source and ducts steam from the
generator tank into the Oven chamber.
To operate the EXTERNAL STEAM option:
A. Make sure the Oven is at the correct operating temperature. Injecting steam into a cold
Oven will cause the steam to condense into water and flood the Oven and product.
B. Set any separate Power Switch for the Steam Generator to the
ON
position.
C. Set the 60–Minute Steam Timer for the duration required.
D. The external Steam Generator will continue to supply steam to the Oven as long as the
Timer does not expire (except for brief 5-10 second periods while the Generator Tank is
refilling).
COOK–N–HOLD OPTION:
The COOK–N–HOLD OPTION allows you to cook a product at one temperature and to hold that
product at a lower temperature.
The 24-Hour Timer along with both the Temperature Control and Hold Control must be set in order
for you to utilize the COOK–N–HOLD option features of your NU–VU® Oven. The Oven
Temperature Control must be set at the desired initial cooking temperature. The Hold Control must
be set at the temperature you wish the product to be held at.
IMPORTANT: Your NU–VU® Oven is well insulated and will maintain the original cook
temperature for ½ hour to 1 hour depending on the product, product density and load
size. The temperature will not instantly drop to the hold setting at the end of the timed
cook cycle. Plan your cook temperature, cook time and hold temperature accordingly to
obtain the best product!
Please follow these general guidelines for preparing meats, fish or fowl:
A. Set the Oven Power Switch to
ON
.
B. Set the Oven Temperature Control to the desired cook temperature.
C. Set the 24–Hour Timer for the length of time you want your product to cook.
D. Set the Hold Control to the desired holding temperature.
E. At the expiration of the cooking time the Hold Control will automatically take over and
maintain your product at the set hold temperature. Remember, the internal Oven
temperature will not drop immediately to the hold temperature, but will slowly decrease
over a period of time until it matches the set hold temperature.
F.
The product will be maintained at the set hold temperature until you remove it from the
Oven, change the setting on the Hold Control or turn the Oven
OFF
.
NOTE: If you desire to pre-heat your Oven before loading any product the 24–Hour
Timer must be set for enough time to pre-heat your unit to the desired temperature. Load
the product when the Oven is pre-heated and then reset the 24–Hour Timer to the correct
IMPORTANT: NEVER USE THE EXTERNAL STEAM OPTION WHEN
YOUR OVEN IS COLD. INJECTING STEAM INTO A COLD OVEN WILL
CAUSE
THE STEAM TO CONDENSE INTO WATER, FLOODING THE OVEN!!!
