"NOTES" alert the user of the manual to pertinent facts and conditions.
WARNINGS
WARNING
TO AVOID ELECTRICAL SHOCK, THIS FURNACE MUST:
1) BE INSTALLED BY A COMPETENT, QUALIFIED ELECTRICIAN WHO INSURES COMPATIBILITY
AMONG FURNACE SPECIFICATIONS, POWER SOURCE AND GROUNDING CODE REQUIREMENTS.
2) ALWAYS BE DISCONNECTED FROM THE POWER SUPPLY PRIOR TO MAINTENANCE AND
SERVICING.
3) HAVE THE DOOR SWITCH OPERATING PROPERLY.
TO AVOID BURNS, THIS FURNACE MUST:
1) NOT BE TOUCHED ON THE EXTERIOR OR INTERIOR FURNACE SURFACES DURING USE OR FOR A
PERIOD OF TIME AFTER USE.
TO AVOID PERSONAL INJURY:
1) DO NOT USE IN THE PRESENCE OF FLAMMABLE OR COMBUSTIBLE CHEMICALS. FIRE OR
EXPLOSION MAY RESULT; THIS DEVICE CONTAINS COMPONENTS WHICH MAY IGNITE SUCH
MATERIALS.
CAUTION: Space unit 3 inches from combustible walls under any condition.
CAUTION: DISCONNECT FROM SUPPLY IF TEMPERATURE EXCEEDS 2000°F.(For Models FC2020P,
FC2025P & FC2028P)
CAUTION: DISCONNECT FROM SUPPLY IF TEMPERATURE EXCEEDS 2150° F.(For Models FC2020P-1,
FC2025P-l & FC2028P-1)

WARNINGS
WARNING
THIS FURNACE CONTAINS REFRACTORY CERAMIC INSULATION WHICH CAN PRODUCE RESPIRABLE
FIBERS AND DUST WHEN HANDLED. THESE FIBERS CAN CAUSE IRRITATION AND CAN AGGRAVATE PREEXISTING RESPIRATORY DISEASE. THE INTERNATIONAL AGENCY FOR RESEARCH ON CANCER (IARC)
HAS CLASSIFIED REFRACTORY CERAMIC FIBER AS POSSIBLY CARCINOGENIC.
AFTER SERVICE REFRACTORY CERAMIC FIBER DUSTS MAY CONTAIN CRYSTALLINE SILICA, WHICH MAY
CAUSE LUNG DAMAGE (SILICOSIS) AND WHICH HAS BEEN CLASSIFIED BY IARC AS A PROBABLE
CARCINOGEN.
CONSULT THE OWNER’S MANUAL FOR THIS EQUIPMENT BEFORE YOU MAKE ANY REPAIRS TO OR
REPLACE ANY PARTS, INCLUDING REPAIRS TO OR REPLACEMENTS OF ELECTRICAL COMPONENTS OR
INSULATING MATERIALS. THE OWNER’S MANUAL CONTAINS INFORMATION AND WARNINGS RELATING
TO THE HAZARDS ASSOCIATED WITH THE REPAIR AND MAINTENANCE OF THIS EQUIPMENT.
WARNING
REFER SERVICING TO QUALIFIED PERSONNEL.
A. Intended Use
The Type 2000 furnaces are general laboratory and heat treating furnaces. Standard models are intended
for applications requiring temperatures from 400°F (204°C) to 1800°F (982°C) for continuous use, or
temperatures from 1800°F (982°C) to 2000°F (1093°C) for intermittent use. High temperature (-1) models
are intended for applications requiring temperatures from 400°F (204°C) to 1950°F (1066°C) for
continuous use, or temperatures from 1950°F (1066°C) to 2150°F (1177°C) for intermittent use.
Continuous use is operating the furnace for more than 3 hours and intermittent use is operating the
furnace for less than 3 hours.
The unit consists of 1) a heating chamber, 2) an automatic proportioning temperature control, 3) a twoposition power switch. See Figure 1 for the overall shape and general features of the unit.
B. Principles of Operation
The furnace chamber is heated by four electric resistance heaters which are embedded In a refractory
material. The chamber is insulated with a ceramic fiber insulation. The temperature is controlled by an
automatic proportioning controller using a chromel/ alumel thermocouple. The control unit is located
under the furnace chamber well Insulated from the furnace chamber.
This furnace is equipped with thermocouple break protection, a door safety switch, and cold junction
compensation. The silicon controlled rectifiers which control power to the heating elements are controlled
by internal circuitry to operate as zero switching devices. This zero switch capability prevents line
interference which can effect other sensitive equipment.
