Provisions for Lifting and Carrying
Before moving the instrument, disconnect all
connections from the rear of the apparatus. Lift the
instrument by grabbing underneath each corner.
Cleaning & Maintenance
Periodic cleaning may be performed on the exterior
surfaces of the controller with a lightly dampened
cloth containing mild soap solution. All power
should be disconnected and the power cord should
be unplugged when cleaning the 4848T Controller.
There are no user serviceable parts inside the
product other than what is specifically called out
and discussed in this manual. Advanced trouble-
shooting instructions beyond the scope of this
manual
can
be
Company in order to determine which part(s) may
be replaced or serviced.
CAUTION! Ensure that any hot surfaces
have had adequate time to cool before
cleaning or maintaining the reactor and/
or its components.
General Specifications
Electrical Ratings
115VAC, 15.0 Amps, 50/60 Hz
230VAC, 15.0 Amps, 50/60 Hz
Before connecting a controller to an electrical outlet,
the user must be certain that the electrical outlet has
an earth ground connection and that the line, load
and other characteristics of the installation do not
exceed the following limits:
Voltage: Fluctuations in the line voltage should not
exceed 10% of the rated nominal voltage shown on
the data plate.
Frequency: Controllers can be operated from either
a 50 or 60 Hertz power supply without affecting
their operation or calibration.

Current: The total current drawn should not exceed
the rating shown on the data plate on the controller
by more than 10 percent.
Thermocouple: Unless otherwise specified, all 4848T
Controllers operate with a Type-J (Iron-Constantan)
thermocouple. The total resistance of the thermo-
couple and the lead wires should not exceed 100
ohms. If the resistance of the thermocouple circuit is
higher, it will not function properly.
Environmental Conditions
This instrument is intended to be used indoors.
CAUTION! Do not use in hazardous
atmospheres.
Operating: 15 ºC to 35 ºC; maximum relative hu-
midity of 80% non-condensing. Installation Cat-
egory II (over voltage) in accordance with IEC 664.
Pollution degree 2 in accordance with IEC 664.
Altitude Limit: 2,000 meters.
Storage: -25 ºC to 65 ºC; 10% to 85% relative humidity.
General Instructions
Set the controller on a sturdy bench or table where
there is convenient access to an electrical outlet
with the appropriate supply voltage and current rat-
ings in accordance with national and local electrical
code requirements. Leave a space of at least twelve
inches between the controller and the heater of the
reactor so that the controller will not be affected by
radiant heat.
