Installing the Integra 750Plus
2. Wrap the threads of the delivery tube (the tube that supplies liquid nitrogen to the
freezer) with PTFE sealing tape, then connect the tube to the 'T' connector on the
back of the freezer. Tighten the nut using a spanner. If required, the delivery tube can
enter the 'T' connector from the opposite direction; simply move the copper pipe
attached to the pressure-relief valve to the opposite side of the 'T' connector (ensuring
that the copper sealing washer is undamaged and in place) and tighten securely.
3. Connect the mains lead to the rear panel of the freezer, but DO NOT connect it to the
mains wall socket.
4. If the rear panel will become difficult to access in the freezer's final position, make
sure that the power switch on the rear panel is on (i.e. press '1'). Otherwise, switch
off the freezer, i.e. press '0'.
5. If appropriate, connect the serial cable (9F-9F one-to-one connections) between the
Serial Port on the rear panel to the PC's serial port, using a 9M-25w adaptor if
necessary. Retain the ESD cover for future use if the cable is subsequently
removed.
Rotate a top-loading freezer
7. If the freezer has been configured for top loading, it now needs to be lifted and rotated
into its correct orientation. Refer to Lifting Instructions at the end of this chapter.
Fit the sample PRT and exhaust elbow
8. Open the freezer's door and plug the sample PRT into the socket (hole) in the top
(front loading) or back (top loading) of the chamber.
9. Fit the plastic exhaust elbow adapter to the exhaust port on the right-hand side of the
freezer. Direct the exhaust gas to the rear of the freezer or connect the adapter to
your own exhaust ducting.
2.4 Installing a Dura-Lo or Dura-Tech
Cylinder
Use the following procedure if your system uses a Dura-Lo or Dura-Tech cylinder.
To install a Dura-Lo or Dura-Tech cylinder
1. Connect the delivery tube to the liquid-nitrogen tap by using an appropriate adapter,
and tighten securely, observing the manufacturer's instructions.
2. Wear gloves and goggles, then open the liquid-nitrogen tap slowly whilst checking for
leaks. Rectify as necessary.
