C.HOLDING MODULE
For Recommended Holding Temperatures, see HM2000 guidelines on page 7.
When equipped with a holding module, your cabinet is designed to maintain the temperature of HOT prepared foods. The holding module is equipped with a thermostatically controlled heater, a blower for air circulation and a water pan. A POWER switch is provided with a red light to indicate when the unit is switched ON. Beside the POWER switch is the TEMPERATURE thermostat and its yellow indicator light.
A three-wire grounded lead cord is supplied fixed to the module. The cord cannot be separated from the module, thus, upon module removal be careful of the cord passing through the cabinet wall. Likewise when installing the module into a cabinet, the cord must first be fed through the opening in the cabinet back panel.
1.With the POWER switch OFF, plug the cord into a standard grounded 20 amp, 125VAC receptacle. REFER TO CABINET DATA PLATE FOR AMPERE RATING.
CAUTION: THE WATER PAN MUST BE IN PLACE DURING MODULE OPERATION.
2.To introduce limited humidity, fill the 11/2-quart capacity water pan to 1/2" from the top with HOT clean tap water. During operation, check the water level every 3 hours and refill as necessary. The unit may be operated without water if humidity is not desired.
3.Snap POWER switch to ON. The red POWER light will now glow as will the yellow indicator light, and the blower will begin circulating air.
NOTE: This is not a foot switch. Using it as a foot switch can damage the switch and make the cabinet inoperable.
4.Turn the TEMPERATURE thermostat to a setting of 10. The holding unit is now in operation.
5.After allowing the cabinet to PREHEAT FOR APPROXIMATELY 45/60 MINUTES, reduce
the thermostat setting to 6/8. In a room of average temperature (72° F), this should provide 150° -170° F. Adjustments to the temperature may be made as necessary.
THIS IS A HOT FOOD HOLDING CABINET AND IS NOT INTENDED TO RETHERMALIZE COLD FOOD. MAKE SURE FOOD AND CABINET ARE AT PROPER TEMPERATURES BEFORE PLACING FOOD IN THE CABINET.
NOTE: The POWER (red) light will glow as soon as the POWER switch is switched ON and will continue to glow until switched OFF. The yellow indicator light will go on and off as the thermostat cycles. The blower will operate as long as the POWER switch is ON. If the yellow light is not illuminated, this indicates that the cabinet has achieved the preset TEMPERATURE level, NOT that the unit has been switched OFF.
4
It is not necessary at the end of the operating day to disrupt the TEMPERATURE setting in order to turn the unit OFF. By switching the POWER switch to OFF, the unit is no longer operating. By switching the POWER switch to ON when resuming operations, the cabinet will attain the preset level.
D.COMBINATION HOLDING/PROOFING MODULE
For Recommended Holding Temperatures, see CM2000 guidelines on page 7.
When equipped with a combination holding/ proofing module, your cabinet is designed for proofing dough products (proof mode) or maintaining the temperature of HOT prepared foods (heat mode). The combination holding/ proofing module is equipped with three thermostatically controlled heaters, a blower for air circulation and a water pan. A POWER switch is provided with a red light to indicate when the unit is switched ON. Beside the POWER switch are the TEMPERATURE and HUMIDITY thermostats, each with a yellow indicator light. Located between the thermostats is the switch for selecting PROOF mode or HEAT (holding) mode operation.
A three-wire grounded lead cord is supplied fixed to the module. The cord cannot be separated from the module, thus, upon module removal be careful of the cord passage through the cabinet wall. Likewise when installing the module into a cabinet, the cord must first be fed through the opening in the cabinet back panel.
Proof Mode Operation
In the PROOF mode, the HUMIDITY thermostat controls the heat element under the water pan to produce moist heat (humidity) while the TEMPERATURE thermostat controls the heat element in the air duct to produce dry heat.
1.With POWER switch OFF, plug lead cord into a standard grounded 20 amp, 125VAC receptacle. REFER TO CABINET DATA PLATE FOR AMPERE RATING.
CAUTION: THE WATER PAN MUST BE IN PLACE DURING MODULE OPERATION.
2.Fill the 21/2-quart capacity water pan to 1/2" from top with HOT clean tap water. During operation, check water level every 2 hours and refill as necessary.
3.Move the selector switch to PROOF position. Snap POWER switch to the ON position. The red POWER light will now glow and the blower will begin operating. NOTE: This is not a foot switch. Using it as a foot switch can damage the switch and make the cabinet inoperable.
4.For products that will proof in 30-45 minutes at approximately 95° F and 95% relative humidity, turn the HUMIDITY thermostat to
setting 10 and TEMPERATURE thermostat to setting 2. Given a normal room temperature of 72° F, a PREHEAT TIME OF APPROXIMATELY 30 MINUTES is required before proofing can begin. For products that require more than 45 minutes to proof, it will probably be necessary to reduce the HUMIDITY setting to avoid a 100% relative humidity condition during the proofing cycle. HUMIDITY SETTINGS THAT ARE TOO HIGH WILL RESULT IN EXCESS WATER CONDENSING ON THE INSIDE OF THE DOOR AND POSSIBLE CABINET LEAKAGE.
Individual adjustments of temperature and humidity may be made as necessary.
NOTE:The POWER (red) light will glow as soon as the POWER switch is switched ON and will continue to glow until switched OFF. The yellow indicator lights will go on and off as their controls cycle; the blower will operate as long as the POWER switch is ON. If the yellow lights are not illuminated, this indicates that the cabinet has achieved the preset levels, NOT that the unit has been switched OFF.
It is not necessary at the end of the operating day to disrupt the TEMPERATURE and HUMIDITY settings in order to turn the unit OFF. By switching the POWER switch to OFF, the unit is no longer operating. By switching the POWER switch to ON when resuming operations, the cabinet will attain the preset levels.
Heat Mode Operation
In the HEAT mode, the TEMPERATURE thermostat controls one heat element in the air duct to produce dry heat.
1.With POWER switch OFF, plug lead cord into a standard grounded 20 amp, 125VAC receptacle. REFER TO CABINET DATA PLATE FOR AMPERE RATING.
CAUTION: THE WATER PAN MUST BE IN PLACE DURING MODULE OPERATION.
2.To introduce limited humidity, fill the water pan to 1/2" from top with HOT clean tap water. During operation, check water level every 3 hours and refill as necessary. The unit may be operated without water if humidity is not desired.
3.Move selector switch to HEAT position. Snap POWER switch to ON. The red POWER light will now glow, as will the yellow indicator light adjacent to the TEMPERATURE thermostat. The blower will begin circulating air. NOTE: This is not a foot switch. Using it as a foot switch can damage the switch and make the cabinet inoperable.
4.Turn the TEMPERATURE thermostat to setting 10. The unit is now operating in the HEAT mode.
5.After allowing the cabinet to PREHEAT FOR APPROXIMATELY 45/60 MINUTES, reduce the thermostat setting to 6/8. In a room of
5
average temperature (72° F), this should provide 150° -170° F. Adjustments to the temperature may be made as necessary.
THIS IS A HOT FOOD HOLDING CABINET AND IS NOT INTENDED TO RETHERMALIZE COLD FOOD. MAKE SURE FOOD AND CABINET ARE AT PROPER TEMPERATURES BEFORE PLACING FOOD IN THE CABINET.
NOTE: The POWER (red) light will glow as soon as the POWER switch is turned ON and will continue to glow until switched OFF. The yellow indicator light(s) will go on and off as their controls cycle. The blower will operate as long as the POWER switch is ON. If the yellow light(s) are not illuminated, this indicates that the cabinet has achieved the preset level(s), NOT that the unit has been switched OFF.
It is not necessary at the end of the operating day to disrupt the TEMPERATURE setting in order to turn the unit OFF. By switching the POWER switch to OFF, the unit is no longer operating. By switching the POWER switch to ON when resuming operations, the cabinet will attain the preset level.
E.PROOFER MODULE
When equipped with a proofer module, your cabinet is designed for proofing dough products. The proof module is equipped with two thermostatically controlled heaters — one for dry heat (TEMPERATURE) and one for moist heat (HUMIDITY), a blower for gentle air circulation and a water pan. A POWER switch is provided with a red light to indicate when the unit is switched ON. Beside the POWER switch are the separate TEMPERATURE and HUMIDITY thermostats, each with a yellow indicator light.
A three-wire grounded lead cord is supplied fixed to the module. The cord cannot be separated from the module, thus, upon module removal be careful of the cord passage through the cabinet wall. Likewise when installing the module into a cabinet, the cord must first be fed through the opening in the cabinet back panel.
1.With POWER switch OFF, plug lead cord into a standard grounded 15-amp, 125VAC receptacle. CAUTION: THE WATER PAN MUST BE IN PLACE DURING MODULE OPERATION.
2.Fill the 21/2-quart capacity water pan to 1/2" from top with HOT clean tap water. During operation, check water level every 2 hours and refill as necessary.
3.Snap POWER switch to the ON position. The red POWER light will now glow and the blower will also begin operating. NOTE: This is not a foot switch. Using it as a foot switch can damage the switch and make the cabinet inoperable.
4.For products that will proof in 30-45 minutes at approximately 95° F and 95% relative humidity, turn the HUMIDITY thermostat to setting 10
and TEMPERATURE thermostat to setting 2. Given a normal room temperature of 72° F, a PREHEAT TIME OF APPROXIMATELY 30 MINUTES is required before proofing can begin. For products that require more than 45 minutes to proof, it will probably be necessary to reduce the HUMIDITY setting to avoid a 100% relative humidity condition during the proofing cycle. HUMIDITY SETTINGS THAT ARE TOO HIGH WILL RESULT IN EXCESS WATER CONDENSING ON THE INSIDE OF THE DOOR AND POSSIBLE CABINET LEAKAGE.
Individual adjustments of temperature and humidity may be made as necessary.
NOTE: The POWER (red) light will glow as soon as the POWER switch is switched ON and will continue to glow until switched OFF. The yellow indicator lights will go on and off as their controls cycle. The blower will operate as long as the POWER switch is ON. If the yellow lights are not illuminated, this indicates that the cabinet has achieved the preset levels, NOT that the unit has been switched OFF.
It is not necessary at the end of the operating day to disrupt the TEMPERATURE and HUMIDITY settings in order to turn the unit off. By switching the POWER switch to OFF, the unit is no longer operating. By switching the POWER switch to ON when resuming operations, the cabinet will attain the preset levels.
