Tubing Connections
Water connections are not required for the 6100 Calorimeter.
The two external water connections are made using the ¼” Nylon tubing, P/N
HJ0025TB035, furnished with the system. For each connection, cut the end of the tube
squarely with a knife or tubing cutter.
The cooling water connections at the rear of the calorimeter use compression fittings.
Insert the tubing into the fitting as far as it will go and then tighten the nut ¾ of a turn
from finger tight. Subsequent connections are made by threading on the nut by hand
and then tightening slightly with a wrench. These compression fittings can be over-
tightened causing a leak in the system.
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. Take care not to
fill the tank with water higher than the tube that enters through the back of the tank
(approximately 4 inches from the top of the reservoir).
Check the voltage requirements of the water handler 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 handling system by flipping the switch to the “ON” position. 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. Fill the tank on the back of the unit as described in the calorimeter
operating manual. (It may be necessary to tip the calorimeter forward slightly to ensure
no air bubbles are trapped in the line.) Plug in the power cord to a suitable electric
outlet. Turn on the calorimeter by flipping the switch to the “ON” position.
Note: Do not turn on the calorimeter heater and pump until the calorimeter
jacket is full otherwise damage can occur to the unit.
