1. Carefully coil the extra probe lead in the compressor compartment,
and secure it to the compartment wall with a tie wrap and tie wrap
anchor provided. Additional tie wraps and anchors may be used to
secure the probe lead to the exterior back wall of the freezer.
2. Loosen the terminal screws on the solenoid. Slide the spade lug
connectors under the screws and tighten to secure.
3. Connect power to the freezer. Turn the freezer On, with battery switch
Off (O).
a. The Solenoid Engaged light on the BUS control panel illuminates
(no injection occurs). This light stays on until the unit is below
BUS setpoint.
b. The Low Battery indicator may also illuminate.
4. Turn the battery switch to Standby mode ( ) to charge both batteries.
The following section describes the configuration and operation of the
BUS.
Warning
When activated, this unit injects liquid nitrogen or carbon
dioxide. Liquid nitrogen can cause serious freezing (frostbite) if it comes in
contact with unprotected skin or eyes. Nitrogen suppresses oxygen levels
and may cause suffocation if area is not well ventilated. Refer to Appendix
A for the proper handling of liquid LN
2
.
s
Caution
Make sure the pressure relief valve on any LN
2
tank is adjusted to
30 PSI maximum blow-off.
s
Warning
Carbon dioxide gas suppresses oxygen levels and may cause
suffocation if area is not well ventilated. Refer to “Handling Liquid CO

in
Appendix B of this manual.
