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.
Operation
Using water with less than 85 ppm total hardness, fill the water tank (P/N A262HW) to
within 10 cm (4 inches) of the top. Take care not to fill the tank with water higher than
the tube that enters through the side of the tank. Approximately 4L (1 gal) will be
required.
Do not apply power to the cooler at this time.
Check the voltage requirements of the system by examining the data label found on the
back of the unit. Plug the power cord into a suitable electrical outlet. Turn on the water
recirculation system by flipping the switch to the “ON” position. This will start the pump
that delivers water through the cooler and on into the calorimeter. Monitor the amount
of water in the water tank. Add water as required to maintain the water level in the
reservoir. Check for water leaks in the external lines and fix as required.
Check the voltage requirements of the calorimeter by examining the data label found on
the back of the unit. Plug in the power cord to a suitable electric outlet. Turn on the
calorimeter by flipping the switch to the “ON” position. This will open a water solenoid
inside the calorimeter that allows the calorimeter jacket to begin filling.
Note: Do not turn on the calorimeter heater and pump until the calorimeter
jacket is full otherwise damage can occur to the unit.
This initial filling process can take upwards of fifteen minutes to complete. During this
time, the pump in the 1564 Water Handling System will cycle on and off as required in
order to maintain pressure in the water lines. As the calorimeter jacket is filled, continue
to add water as required in order to maintain the water level in the reservoir of the water
handling system.
Make sure that the voltage requirements of the water cooler correspond to the rating on
the data plate. After the calorimeter jacket is filled and the water level in the water tank
of the 1564 Water Handling System tank has reached equilibrium, apply power to the
water cooler. Activate the calorimeter heater and pump.
Note: Allow one-half hour for these units to reach their normal operating
temperature.
