1. Carefully remove the unit from the crate and place it close to a water
supply and drain.
Coolant Supply and Coolant Drain lines are ¼" tube connections and the
Coolant Supply port should be connected to a 40 PSI (275.8 kPa) water
source. The Coolant Drain is the port located on the right of the lower
back instrument panel.
2. Fill the bath with approximately 2 gallons of mineral oil to submerge the
test cells at least half way. The oil must cover the thermocouple inside the
bath.
Do not overfill the bath.
3. Connect the unit to a grounded and fused 10-amp electrical supply.
4. The rotational speed of the unit may need to be adjusted periodically.
a. Turn on the electrical power and start the motor.
b. Measure the rotational speed of the rotators with a hand held
tachometer. The rotational speed should be 150 rpm ± 15.
c. If adjustment is required, loosen the three screws on the back panel
of the unit and open the door. Directly to the right of the motor is the
motor speed potentiometer.
d.
To increase the rotational speed, turn the potentiometer speed control
clockwise. Turn it counterclockwise to reduce the speed.
