System Start Up
1.
Remove the CryotechFlex hose from the GN
2
outlet with a 7/8” open end wrench or adjustable crescent
wrench.
2.
Insert the supplied 10 micron filter into the male bayonet on the supplied 10 foot CryotechFlex hose
using a 1/8” allen wrench.
3.
Attach the CryotechFlex hose (male bayonet side) to the UltraDoser
®
LN
2
Dosing System unit with the
supplied bayonet clamp and gasket.
4.
Attach the CryotechFlex hose (female flare fitting side) to the 22psi LN
2
Dura-Cyl
®
Liquid Cylinder.
5.
Open the liquid valve (counter-clockwise direction) on the Dura-Cyl liquid cylinder.
6.
Wait until the UltraDoser unit is filled with liquid nitrogen, approximately 10 minutes.
7.
Turn the controller “ON”. The front panel will show the Home screen if the controller is functioning
correctly.
8.
Place the DOSE ENABLE switch on the controller to the “0” position. This will prevent the UltraDoser
system from dosing until the operator is ready.
9.
Adjust the dosing parameters. See “500S Controller Adjustments” on page 23 for additional
information.
10.
Place the DOSE ENABLE switch on the controller to the “I” position. This will allow the unit to begin
dosing.
IMPORTANT: When the UltraDoser unit is filling, it will vent heavily and there will be a steady stream of
“fog” from the vent. Once the UltraDoser unit is filled, there will be a “wisp” of fog coming from the vent. If
the UltraDoser unit overfills and liquid nitrogen starts dripping out the vent, close the liquid valve on the Dura-
Cyl
cylinder and call Chart service at +1 408.371.4932.
System Shut Down
1.
Place the DOSE ENABLE switch on the controller to the “0” position. This will stop the machine from
dosing nitrogen.
2.
Shut the liquid valve (clockwise direction) on the Dura-Cyl cylinder.
3.
If possible, purge with GN
2
until next use. See “Purging with Gaseous Nitrogen” on page 34 for
additional information.
IMPORTANT: Turn the Dose Enable switch to the off “0” position if the system will not be used for a period of
time; example an 8 hour shift. This will disable the dosing function but allow the system to continue to supply
power to the dosing and vent heaters to prevent ice build-up.
Dura-Cyl cylinder (22psi) Change Out Procedure
The Dura-Cyl cylinder will need to be changed out from time to time. The operator should visually check the
gauges on the Dura-Cyl cylinder to monitor the internal liquid level. When the gauges read low levels, it must
be swapped with a full Dura-Cyl cylinder.
1.
Shut the liquid valve (counter-clockwise direction) on the Dura-Cyl cylinder.
2.
Disconnect the CryotechFlex hose from the Dura-Cyl cylinder using a 7/8” open end wrench or
adjustable crescent wrench.
3.
Connect the CryotechFlex hose to the liquid outlet on the full Dura-Cyl cylinder using a 7/8” open end
wrench or adjustable crescent wrench.
IMPORTANT: The UltraDoser 500S system will continue to dose properly until the liquid level inside the
UltraDoser unit runs low. This feature gives the operator a reasonable window in which to change out the Dura-
Cyl cylinder without disrupting the production operation.
