Assembly

1. Position the Control Chassis in its desired location for operation.

2. Place the Bath Vessel Housing on top of the Control Chassis. The

rear mounted alignment bolt on the top rear of the Control Chassis
must mate with the hole in the alignment bracket on the bottom rear
of the upper Bath Vessel Housing.

3. Secure the connection with the supplied cap nut. The cap nut should

only be finger-tightened (see 

Figure 2

).

4. Position the Overflow Jar on the rear platform. If the jar platform has

not yet been installed, follow the platform installation instructions in
the following section of this manual.

5. Slide the tubing from the Control Chassis reciprocating pump onto

the connector on the bottom of the Overflow Jar. Ensure that the
connection is secure.

6. Place the drain tube from the bath into the Overflow Jar through the

circular opening in the cap of the Overflow Jar.

Pneumatic connections

The pneumatic connections on the TE-1500 provide the bath agitation
and subsequent stirring by recirculating the bath vapors. To complete
pneumatic connections, locate the two silicone tube assemblies. These
assemblies have quick-connect bayonet style connectors on their ends.

„

Attach one of the tube assemblies to the 

AIR OUT

 connection on the

Control Chassis. Attach the other end of the assembly to its mating
connection on the Bath Vessel Housing (see 

Figure 3

, next page).

Attach the other assembly to the 

AIR IN

 connection on the Control

Chassis. Attach the other end of the assembly to its mating connec-
tion on the Bath Vessel Housing. To secure the connections, insert the
bayonet connector from each hose into its mating connection and
turn clockwise 1/8 turn to lock.

Electrical connections

The electrical connections on the TE-1500 provide power to the instru-
ment and transfer bath power (AC and DC) from the Control Chassis to
operational components built into the Bath Vessel Housing (see 

Figure

3

). Sensor information from the temperature probe is transferred to the

Control Chassis via the 

TEMP PROBE 

connection.
