Assemble the Reactor
These reactors require at least 10 square feet of work-
space in a well-ventilated area with convenient access
to an electric outlet, running water and a drain. This
unit needs to be placed at least 10 inches away from
walls or flammable materials.
1. Set the Reactor Controller near the reactor, leaving
a space of at least six inches between the controller
and the base of the reactor so that the controller
will not be unduly affected by radiant heat. Con-
nect the reactor to the controller using information
contained in its Instruction Manual No. 548M or
follow the steps below.
Labeled connections are provided on the rear panel
of the controller.
Parr Cooling Only:
The Parr Cooling output connector is to be used
only with Parr Instrument Company cooling sole-
noid valve assemblies supplied with the appropri-
ate cooling power cord.
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.
Note: Do not make connections to a Variac,
Powerstat or the like to attempt to control the
heating output. The heavy inductive load on
the primary side of such devices can destroy
the internal sold state relay located in the 4848
controller.
Parr Motor Only:
The Motor output connector is to be used only with
Parr Instrument Company motor assemblies sup-
plied with the appropriate motor power cord.
2A. Vessels on movable cart.
The motor is contained in the overarm assembly
attached to the cart. The overarm assembly pivots
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 magnetic stirrer.
2B. Vessels on stationary stand.
Bolt the stand to the bench/floor 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 assembly. If fixed
head style, position the head in the slot located in
the front midplate. If removable 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.
3. Connect the power cord from the heater into the
heater socket on the rear panel of the controller.
4. Plug the motor power cord into the motor socket
on the rear of the controller.
Secure the clamp on the motor cord
with the provided screw next to the
motor socket for safety purposes.
5. Note the voltage requirement on the controller
identification label on the back panel, and then
plug the power cord into an appropriate outlet.
Power for these reactors should be drawn from a
3-slot, grounded outlet capable of carrying up 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 Reactor Controller.
8. Connect cooling water to internal cooling coil if
installed.
9. Connect cooling water to the magnetic stirrer. See
manual no. 234M.
10. Connect tubing to the rupture disc outlet and run
to a safely vented area. See manual no. 231M.
11. Using the switch on the Reactor Controller, turn on
the motor for a short run to check the stirrer drive
system.
