Installation
On Millennium Series systems, the Heating Element and Temperature Controller is installed
at the Asymtek factory. For Century Series systems, you need to install the Heating Element
and Temperature Controller. Consult the dispensing system installation manual and refer to
those Temperature Controller installation procedures. If this manual is not available, follow
the procedures below.
Only a service technician should perform these installation procedures.
To install the Heating Element:
1. Loosen the thumbscrew on the front of the heating element.
2. Do one of the following, depending on your type of heating element:
a)
For the HT-04, slide the heating element onto the needle and onto
the valve tip (see Figure 12-5).
b)
For the HT-06, slide the heating element onto the needle and onto
the luer lock fitting (see Figure 12-5).
c)
For the HT-10N, insert the needle into the heating element side slot. The
heating element attaches directly to the needle (see Figure 12-6).
3. Tighten the thumbscrew on the front of the heating element.
Do not over tighten the thumbscrew. Over tightening could
damage the needle
.
4. Plug the J-type thermocouple cable and the Needle Heater power cable into the
power outlets labeled
Needle Heater
on the under side of the dispensing head.
To install the Temperature Controller:
1.
Place the Temperature Controller so that the rear panel is accessible.
If you have a Century Series Workstation, place the controller in the lower
front cabinet. If you do not have a Workstation, place it on top of the
dispensing system.
2.
Plug the power cable into a factory power outlet.
See “Specifications” at the end of this section for power requirements.
3.
Plug the J-type thermocouple cable and the needle heater power cable extension
cords into the appropriate connectors on the back of the Temperature Controller.
