OPERATING
INSTRUCTIONS
DAILY OPERATING PROCEDURES
CAUTION: Make certain evaporator has an adequate supply of water prior to turning
on power switch. Water level should be approximately 1” (2.5 cm) from overflow.
1. Set appropriate temperatures. Food temperature is selected with the FOOD
TEMPERATURE (EVAPORATOR) control (set in accordance with local health
codes). Food Texture is selected with the FOOD TEXTURE (AIR) control. See
Holding Guidelines on Page 9 for specific settings.
Food Holding Reference Chart
PRODUCT FOOD TEMP FOOD TEXTURE
Very moist foods - Sauces, gravies, vegetables, etc. 140˚F +5˚F
Soft moist foods - Bakery, meats, fish, chicken, etc. 140˚F +10˚F
Firm moist foods - Finger foods, baked potatoes, etc. 140˚F +15-30˚F
Crisp dry foods - Crispy fried chicken, french fries, etc. 140˚F + 50-60˚F
See Holding Guidelines Chart on page 9 for more product recommendations with F/C settings.
NOTE: 1. The actual temperature of crisp dry foods may substantially exceed
optimal serving temperatures ... making it necessary to reduce the
FOOD TEMPERATURE (EVAP) setting as much as 20-30°F to obtain
the desired temperature.
2. Total Food Texture (air temperature) setting equals the addition of the
FOOD TEMPERATURE (evaporator temperature) and FOOD TEXTURE
settings. For example, a FOOD TEMPERATURE setting of 140˚F and a
FOOD TEXTURE setting of +10˚F is equal to an evaporator temperature
of 140˚F and an air temperature of 150˚F (140˚F+10˚F).
2. Fill EVAPORATOR (for locations with hard water add 1 tablespoon white vinegar
or lemon juice to water in evaporator to help prevent scale buildup). Get advice
from your local water authority concerning possible water treatment necessary
for the protection of the unit. Some water supplies are high enough in chemical
content to be capable of destroying stainless steel if used untreated. While the
water may be of low chemical content when fed into the evaporator, the
evaporation process may concentrate the chemicals to a level which could cause
a high interaction with the stainless steel. When available water is of unknown
quality, automatic fill (optional) units should be connected to the water source
through a deionizer/demineralizer. Failure to do so will void the warranty!
3. Toggle Power Switch on. Allow 30 minutes for warm-up.
4. Insert food.
5. Adjust FOOD TEMPERATURE or FOOD TEXTURE dials as needed to maintain
desired food quality.
KEEP DOOR(S) CLOSED WHEN NOT IN USE. If food temperature becomes
too low during serving period, increase FOOD TEMPERATURE
(EVAPORATOR) setting by 10-20°F to maintain desired food temperature.
