The Seal Safe System
.
Caution: The ground jaw has an indentation in which the
spring must rest. Failure to properly seat the spring in the
indentation can damage the spring and cause inadequate
tubing seals.
2
Find the mating grooves on both sides of the RF jaw assembly. Fit
the ground jaw into the mating grooves and slide it down the RF
jaw assembly shaft to the spring. Ensure the spring fits into the
indentation in the ground jaw (see Figure 15-19).
3
Use your thumb to slightly depress the ground jaw. Ensure the
spring stays in place.
4
Replace the lever as follows:
a Tip the lever at a 45° angle to allow the roller to sit on the
ground jaw stop (see Figure 15-20). Position the lever pivots
behind and below the pivot slots.

c When you release your thumb, the lever should fully engage
and secure the ground jaw on the cutter/sealer head.
5
Ensure the cutter/sealer head mechanically functions by squeezing
the lever. If the jaws do not close completely, check the seating of
the spring.
6
Attach a splash guard if required (see "Replacing a Splash Guard" on
page 15-6).
7
Reconnect the cutter/sealer to the RF electronics enclosure by
connecting the RF interconnect cable at the cutter/sealer head.
The Seal Safe system is ready to use.

Technician Maintenance

Preventive Maintenance
To prolong the life and ensure maximum performance of the Seal Safe
system, a Gambro-trained technician must perform the preventive
maintenance (PM) procedures found in the appropriate service PM kit.
The Seal Safe system has a twelve-month PM schedule. Gambro BCT
recommends a PM performance compliance window of ±30 days from
the PM anniversary.
Servicing
Warning: To avoid electric shock, DO NOT open the head of the
Seal Safe system during servicing of the cutter/sealer head. Refer
servicing to a qualified technician.
