INSTALLATION INSTRUCTIONS

HC-UA-11 FOR PROPANE CYLINDER INSTALLATION:

This cabinet is not intended for use with natural gas.
It is not user-convertible to natural gas.

1. Only use a 1 lb. standard cylinder marked “PROPANE”. A larger tank can be used with an adapter (optional
accessory part number 0904-026-K See installation FL-2362).

2. The cylinder must be constructed and marked in accordance with the specications for propane cylinders of the
U.S. Department of Transportation (DOT) or CAN/CSA B339.

3. The Cylinder should not be allowed to remain in a high heat area, such as a car, truck or direct sunlight. DO NOT

store at temperatures above 120°F (49° C) and in unauthorized storage areas not intended for cylinder storage.

4. Hold and use the cylinder in an upright position and only use when temperatures are above 10°F (-12° C). Do not
attach near ames, pilot lights or sparks.

5. Propane Tank Hook-up:

a. Make sure the cabinet switch is in the “OFF” position.

b. Uncap the cylinder, hold upright and insert it in the right rear compartment of the cabinet. Hand screw and
tighten the cylinder to the gas regulator. DO NOT over-tighten.

Check for leaks at the connection: Spray soapy water onto the connection and look for bubbles. Tighten more if
needed.

6. Disconnect the cylinder when not in use. Replace the cylinder cap when storing.

HC-UA-11-NG FOR NATURAL GAS INSTALLATION ONLY:

1. Installation shall be made with a connector that complies with Standards for Natural Gas Connection on

Movable Appliances ANSI/Z21.69b/CSA 6.166-2006.

Adequate means to limit the movement of the cabinet without

CAUTION

2. The cabinet and its individual shutoff valve must be disconnected from the gas supply piping system during
any pressure testing of the system at pressures exceeding 1/12 psig (3.45 kPA). During pressure testing
of the gas supply piping system at pressures equal to or less than 1/2 psig (3.45 kPA), the cabinet must be

isolated by closing the manual shutoff valve.

depending on the connector, quick connect or associated piping
must be provided by the installer.

3. Check for leaks at the connection: Spray soapy water onto the connection and look for bubbles. Tighten more if
needed.

Instructions)

Push the switch to “GAS”. Preheat cabinet for 45
minutes.

NOTES: New tanks may not light on the rst couple

tries. See “Re-light Burner” instructions.

1 lb. propane tank will provide approximately 6 hours
of heat at 160°F.

FOR NATURAL GAS OPERATION:

Specications: 8,700 BTU at W.C.

Notes about using gas:

1. GAS RESET LIGHT:

a) Red light on control panel will come on and

when it should be.

b) Propane tank may be empty or a draft has blown

out the burner ames.

c) To re-light the burner: Push switch to “Off”

and then back to “Gas” quickly.

d) Wait for up to 10 seconds and then check sight

glass below the door to see the burner ames.

Repeat as necessary.

Specications: 120 Volts, 1500 Watts, 60 Hz., 1 Ph.

12.5 Amps, 15 Amp. Service (NEMA 5-15P)

Plug the power cord into the proper wall outlet and
push switch to “ELECTRIC”.

Preheat cabinet for 30 minutes.

Call Service if alarm goes off repeatedly without ignition.

DO NOT ATTEMPT
TO LIGHT BY
HAND.

This cabinet has an automatic ignition system.

2. The battery (needed for the gas valve and the
temperature control) keeps charging as long as the
cord is plugged into the outlet (or when accessory
solar panel is added). Check the battery indicator on
the control panel.

NOTE: The battery will provide power for approximately

16 hours (without solar) before needing a charge;
depending on the age and condition of the battery.

when door is opened.

FIRST TIME START-UP:

1. Push the POWER switch to “ELECTRIC”, and

run the unit for one hour at 200°F.

HOW TO HOLD:

1. Push POWER switch on to “GAS” or “ELECTRIC”.

2. Push the “SET” button on the TEMPERATURE
CONTROL. The TEMPERATURE DISPLAY will
show “SP1” (set point 1).

3. Press “SET” again and the current set point temperature
will be displayed.

NOTE: DO NOT PUT FOOD INTO CABINET!
This step is to burn off manufacturing oils and excess

adhesive.

4. Press the   ADJUST buttons to adjust to the
desired temperature.

5. Press “SET” to save the temperature setting.

2. Let the cabinet cool and wipe inside clean with

detergent and hot water before rst use.

6. Preheat cabinet for 45 minutes.

7. Put product into cabinet.

NOTE: Proper food holding temperature is

140°F/60°C or higher.

USING ACCESSORY SOLAR PANEL (Optional):

The solar panel is used to increase the time between battery charges when using the cabinet unplugged in gas
mode. To use the solar system, ensure the solar panel cord is plugged into the solar jack, located in the top right
corner of the back panel of the unit. Rotate the cabinet and/or tilt the solar panel in order to catch the sunlight.

The best possible condition for solar charging is when the sunrays hit the panel straight on at 90° angle.

NOTE: It is recommended to keep the solar panel plugged in even when not in use. It will safely maintain the

battery at full charge for an unlimited amount of time if not placed in a dark area. The solar system is
not powerful enough to charge the battery from fully drained status in any reasonable amount of time.
If the battery is fully dead, plug the cabinet in to a grounded 120V outlet to charge.

TROUBLE-SHOOTING

FAILURE POSSIBLE CAUSE

1. Unit does not turn on (electric mode). 1a. Power cord is not plugged in.
1b. Branch circuit breaker is tripped.
1c. Fuse is blown.

2. Unit does not turn on (gas mode). 2a. Battery is low on charge. Plug power cord in for at

least an hour to charge battery (this time may vary

depending on state of battery).

2b. Fuse is blown.

NOTE: The power cord can be left plugged in for a long period of time after the battery is fully charged. The

internal battery charger will safely “maintain” the battery.

3. Unit heats up slowly. 3a. Check operating instructions for preheat times.

3b. Defective electrical or gas components.

4. Unit does not heat (electric mode). 4a. Unit is not on.
4b. Thermostat is set too low.

4c. Defective electrical components.

5. Unit does not heat (gas mode). 5a. Unit is not on.
5b. Thermostat is set too low.
5c. Propane/gas tank has expired.

5d. A gust of wind may have blown out the ame or

prevented ignition of the gas.

5e. Defective electrical components.

NOTE: The control is equipped with an auto-ignite system. On startup and periodically throughout operation,

it will attempt to ignite the gas for 10 seconds. If it fails, the “reset” indicator will illuminate and an
audible alarm will sound, indicating no heat. If the tank is empty, this will usually happen within 20
seconds, in windy conditions, it could take up to 5 minutes for the alarm to become present. If this
happens, turn the power switch to “OFF” and then back to “GAS”, and it will try to re-ignite.

6. Unit gets too hot or won’t shut off. 6a. Defective electrical components.

For repairs, refer to our list of Authorized Service Centers, FL-1400

NOTE: If any panel which is sealed with silicone needs to be removed for servicing by an authorized personnel,

the exterior seams need to be sealed with a food grade caulking material (certied against NSF/ANSI 51).
