1. Before cleaning, unplug the cabinet.

2. Racks or shelves are easily removed without tools for cleaning. Simply
lift up and pull out. The tray slides may be hand washed or run through
an automatic washer.

3. If applicable, vinyl trim or laminate should be washed with a chlorine-free
detergent and water. Rinse thoroughly with clear water and allow to dry.
Never use abrasive cleaners, waxes, car polish or substances containing
strong aromatic solvents or alcohol. Caution: When using solvents, it is
essential that proper precautionary measures be observed. Refer to
solvent manufacturer's instructions. Us e of direct steam/hot water
cleaning at temperatures above 190°F may result in "bubbling" or
loosening of vinyl adhesive.

4. To clean stainless steel surfaces use only cleansers, detergents,
degreasers, or sanitizers that are certified to be "chloride-free" and
"phosphate-free," and cleansers, degreasers, or sanitizers only in the
recommended concentrations. DO NOT exceed recommended
concentrations or mixing ratios. After cleaning and sanitizing, rinse all
exposed surfaces thoroughly with large amounts of clear water. Wipe off
any standing liquid or residue from all surfaces, corners, or near edges.

CAUTION: Do not use steel wool pads as they will result in rusting from the ferrous metal in the pads.

Cabinet Operations

Do not plug into ungrounded receptacle. Check to ensure that
heater plug is in safe operating condition.

1. Familiarize yourself with the control panel located in lower left of center
section in the front of the cabinet. The control panel contains the
following:

-White light (ON) indicates unit is plugged into electrical outlet
and power is on.

-Thermostat knob is for heated section. Turn knob clockwise to
increase temperature and counterclockwise to decrease
temperature to off position.

2. Plug the cabinet into proper outlet and turn power switch on. The white
light will illuminate indicating the heating and the refrigerating units are
on and working. Food serving temperature will vary with the mass,
type and quantities of food served. Set the thermostat for the desired
holding setting. Turn clockwise to increase the temperature and
counterclockwise to decrease the temperature.

NOTE: On the initial start-up time, allow approximately 45 minutes with
doors closed to reach operating temperature for both sections. Heated
range 140°F to 180°F. Refrigerated range 38°F-42°F.

3. The HC75 provides complete service for twenty patients using half
size trays in the hot and cold sections. Trays are supplied with the
cabinet. The full size serving tra ys are stored in the center work area
AT ROOM TEMPERATURE eliminating the unpleasant effect of a
patient receiving a hot or cold serving tray. Reassembly of hot and
cold trays is fast and simple as each patient's hot and companion cold
tray is removed from its compartment and placed on the serving tray
and then delivered to the bedside.

4. During loading, the cabinet temperature will drop. Try not to move the
cart right away: wait 10 -15 minutes until the cabinet recovers air
temperature. After loading the t rays, place the loaded hot and cold half
trays in their respective hot and cold sections in the cabinet, on the
matching tray slides in the hot and cold sections, in the order they are
to be served.

NOTE: When loading the cabinet be sure to keep the unit plugged in.
DO NOT keep the doors open unnecessarily. Be sure the hot foods you
are dishing up are hot when put into the cabinet. Your food should be
as hot as, or hotter, than serving temperature when put into the cabinet.
The cabinet is designed for food holding, not cooking. If your food is
cool when inserted, it will not reach serving temperature. After loading
be sure the doors are kept closed at all times. Keep the cabinet
plugged in at all times. In loading the refrigerated compartment keep
doors closed as much as possible and put food in at serving
temperature. If food is warm when inserted, it will not reach serving
temperature. After loading be sure the doors are kept closed at all
times and the compartment is allowed to recover to the desired
temperature.

5. Be sure to remove the plug from the outlet and wind the cord on the cord
bracket or push handle before moving the cart. Move the cart to the service
area as quickly as possible.

6. Upon reaching the serving area, unwind the power cord and reconn ect the
heater as quickly as possible. Wait 5-10 minutes (check the thermometer to
see if the temperature is at the desired level). If not, adjust the thermostat as
required.

Calibration

THERMOSTAT CALIBRATION

Maintenance
Instructions

If additional heat range is required in the heating unit, unplug unit,
remove thermostat knob, insert small straight blade screwdriver into
opening and turn limit control set screw counterclockwise (not
clockwise) on e full turn. Replace thermostat knob and turn clockwise to
reach new maximum temperature. Repeat this until desired temperature
is reached. Each 1/4 turn of the calibration set screw will raise the
element heating capacity by approximately 25°F -35°F.

If a reduction of heat is desired, turn limit control set screw clockwise
one full turn. Hold the door open allowing unit to cool until inside
temperature is below the temperature desired. Close the door and allow
unit to rise to new maximum temperature. Repe at this until desired
temperature is reached.

THERMOMETER CALIBRATION

Place an oven thermometer in the center of the cabinet. Turn heater
on; turn thermostat to maximum setting and wait approximately 45
minutes. Open the door and check inside thermometer temperature.
If recalibration is required, pry the plastic cover off the dial body and
with a small flat blade screwdriver insert into the pointer as shown.
Carefully turn the pointer with your finger to the correct setting. Be
careful not to bend the po inter, it is very fragile.

CASTERS

Some casters are equipped with Zerk grease fitting so that they may be
easily lubricated with a grease gun. Recommended lubrication is at least
once every six months. Lubrication will be required more often if carts are
cleaned with a hot water or steam cleaning system. Casters with special
bearings are recommended for frequent cart wash or steam cleaning
situations.

LATCHES

Check frequently to insure that all door latches are secure. Latches may
become "sticky" due to residue buildup from daily use and cleaning.
Lubricate latches regularly with WD-40, silicone spray, graphite or other
commercial lubricants for stainless steel products. Do not use oil.

PERIMETER BUMPERS

If applicable, vinyl which has been dislodged from the channel due
to severe bumping or scraping can be pried back into place with a
common screwdriver.
