shipment. Unpack the calorimeter and carefully check the individual parts against the
packing list. If shipping damage is discovered, save the packing cartons and report it

This apparatus is to be used indoors. It requires at least 4 square feet of workspace on a
sturdy bench or table in a well-ventilated area with convenient access to an electric
outlet, running water and a drain. The supply voltage must be within ± 10% of marked
nominal voltage on the apparatus. The supply voltage receptacle must have an earth
ground connection.
When Swagelok Tube Fittings are used, the instructions for installation are:
1. Simply insert the tubing into the Swagelok Tube Fitting. Make sure that the
tubing rests firmly on the shoulder of the fitting and that the nut is finger-
tight.
2. Before tightening the Swagelok nut, scribe the nut at the 6 o’clock position.
3. While holding the fitting body steady with a back-up wrench, tighten the nut
1-1/4 turns. Watch the scribe mark, make one complete revolution and
continue to the 9 o’clock position.
4. For 3/16" and 4mm or smaller tube fittings, tighten the Swagelok nut 3/4 turns
from finger-tight.
Swagelok tubing connections can be disconnected and retightened many times. The
same reliable leak-proof seal can be obtained every time the connection is remade using
the simple two-step procedure.
1. Insert the tubing with pre-swaged ferrules into the fitting body until the front
ferrule seats.
2. Tighten the nut by hand. Rotate the nut to the original position with a wrench.
An increase in resistance will be encountered at the original position. Then
