Parr Heating Only:
The Parr Heating output connector is to be used
only with Parr Instrument Company heater assem-
blies supplied with the appropriate heater power
cord.
Motor:
Secure the clamp on motor cord to the
controller with the provided screw next to
the motor socket for safety purposes.
The Motor output connector is to be used only with
Parr Instrument Company motor assemblies sup-

2A. Vessels on movable cart.
The motor is contained in the overarm assembly
attached to the cart. The overarm assembly piv-
ots to the rear to allow the vessel to be placed in
the heater. The overarm is then aligned atop the
vessel. Pull up on the release knob to allow the
upper drive shaft to be connected to the mag-
netic stirrer.
2B. Vessels on stationary stand.
Bolt the stand to the fl oor using the
holes in the base plate.
Loosen the panel screw holding the vessel
retainer to the front midplate. Open the vessel
retainer to allow the placement of the vessel as-
sembly. If fi xed head style, position the head in
the slot located in the front midplate. If remov-
able head style, place vessel assembly such that
the split ring rests on midplate bracket. After
installing the vessel, close the vessel retainer
and retighten the panel screw. Pull up on the
release knob located at the top of the belt guard.
This knob is attached to the upper drive shaft
and the universal coupling. Lifting the knob will
allow the alignment of the universal coupling
and the drive adapter attached to the magnetic
drive. Turn the knob to align the slot in the drive
adapter with the universal coupling.

to the full current rating of the system.
6. Connect the thermocouple extension wire to
both the thermocouple and to the controller in
the “Primary Temp Input” position on the rear
panel. Insert the thermocouple into thermowell.
7. Connect leads from accessory packages such as
tachometer, pressure transducer and high temp
cut-off to the designated positions on the back
panel of the 4848 Controller.
8. Connect cooling water to internal cooling coil if
installed.
9. Connect cooling water to the magnetic stirrer.
