CAUTION
Do not bend the nitrogen flex line to less than 5 inch (12 cm) radius or permanent
damage may occur.
This type of damage is not covered under the warranty.
•
Connect one end of the nitrogen flex line to the quick connect fitting attached to the
nitrogen generator. To make the connection, push the hose end coupling onto the
mating coupling on the nitrogen generator outlet. A click will be heard when the
couplings are locked together.
Figure 6-7: Connecting the nitrogen flex line
•
Connect the opposite end of the nitrogen flex line to the quick connect fitting attached
to the low pressure regulator on the dewar.
•
To unlock the couplings, push the flared section of the female coupling towards the
red collar on the male coupling. Once unlocked, the couplings can be separated.
6.10 Electrical protection device installation (option)
The electrical protection device (EPD) is an optional item. If the system was not supplied
with an EPD, proceed to the next section.
•
The EPD is housed in a wall mountable electrical enclosure.
•
The enclosure is not waterproof and should be mounted in a suitable location away
from rain, spray, and condensation.
•
The operating temperature range of the EPD is -40
°
F to 150
°
F (-40
°
C to 65
°
C).
•
When selecting a mounting location, allow clearance to access and open the
enclosure’s hinged panel.
•
The orientation of the EPD is not critical for its operation.
•
It is fitted with a power cord that attaches to the front panel of the helium compressor
package. Make certain the power cord is long enough to reach the front panel
receptacle on the helium compressor package. Please contact Cryomech if a longer
power cord is required.
6.10.1 Connect the electrical protection device to the helium compressor
1)
To connect the EPD’s power cord to the compressor, align the pins on the plug with
the grooves on the mating receptacle located on the front panel of the helium
compressor.
