OPERATING VHL2 & VHL3 WITH PRE-VENT COMPARTMENT CONTROLS
1. Prepare vegetables, fruits, meats, seafood and poultry as you would for steam cooking or
cooking in water: clean, separate, cut, remove stems, etc., and place in a pan.
2. Place loaded pans in the compartment and close the compartment door. Turn the door screw
handle clockwise to seal the door gasket. Normal pressure will seal the compartment;
however, a new gasket may require additional pressure after it becomes heated. After the
pressure gauge (located below the lowest compartment controls) reaches a maximum
pressure of 5 to 6 psi, turn the door screw handle clockwise enough to stop the leakage. The
pressure gauge indicates steam pressure in the steam supply pipe, not the compartments.
3. The timer knob must be turned to 10 minutes or beyond to trip the switches. The knob may
then be turned back to a lower setting if a shorter time setting is desired.
4. Set the timer to the desired cooking time.
5. Press the top half of the compartment switch located under the timer. Steam enters the
compartment during this automatic pre-vent or defrost period; the drain is open to allow any
air and condensate to freely vent.
6. After the cavity reaches a temperature of 180°F (
82°C), preheating and defrosting are
complete: then the drain closes and the timer starts. During the cooking cycle, the
compartment pressure reaches 5 to 6 psi, and limited venting takes place through the
compartment drain to allow removal of condensate and residual air.
7. When the timer reaches 1 minute, the steam supply to the compartment is shut off and the
drain is opened. The compartment will exhaust for about 1 minute.
Never attempt to open the compartment door during the cooking cycle, when the
cooking light is lit or before the buzzer sounds.
8. When the timer reaches 0, the cook light goes off and the continuous buzzer will sound,
indicating the end of the cooking cycle.
9. Turn buzzer off by pressing the bottom half of the compartment switch. Then loosen the door
screw handle slowly to allow moisture to escape. After a few seconds, move the door latch
to the left, slowly open the door and remove the pans of food.
