vacuum trap assembly or the suction regulator. Doing so may permanently damage
the suction regulator and void any and all warranties, express or implied.
A collection canister (reusable or disposable) MUST be used between the patient
and the suction regulator or vacuum trap, if used. If a vacuum trap is not used it is
recommended that a disposable hydrophobic bacterial filter be used between the
suction canister and the suction regulator to prevent overflow of the canister into
the suction regulator. Use of these filters may also prevent build up of aerosolized
particulate inside the suction regulator, thus reducing maintenance requirements
and extending the life of the unit.
VERIFYING REGULATOR OPERATION
NOTE: The proper operation of the suction regulator must be verified prior to each
use. Should the regulator not operate in accordance with the following, it must be
repaired by authorized personnel.
1)
Ensure that the Mode selector is in the OFF (center) positi
on.
2)
Connect the regulator to a vacuum source (normally the wall-mounted in
let).
3)
Occlude the regulator inlet, and turn the adjustment knob one full
turn
clock
w
ise.
4)
Verify that the gauge needle does not move from the “0”
position.
5)
Move the Mode selector to the “REG” positi
on.
6)
Occlude the regulator inlet, and turn the adjustment knob counter-clockw
ise
until the g
auge needle is
at 0.
7)
Keeping the inlet occluded, turn the adjustment knob one full turn clockw
ise.
The gaug
e should read between 120 and 170 mm
Hg.
8)
Keeping the inlet occluded, turn the adjustment knob fully clockwise. Th
e
gauge n
eedle should move clockwise to the highest vacuum se
tting.
9)
Move the Mode selector to the “FULL” positi
on.
10)
Occlude the regulator inlet. The gauge needle should move to the high
est
vacuum setting.
11)
Turning the adjustment knob should have no effect on the gauge reading wh
en
the selector kn
ob is in the FULL position
.
12)
Move the Mode selector to the “OFF” position. The needle should return to 0
If the regulator passes all of the above, it is ready for patient use. Failure of any of
the above requires that the unit be serviced by authorized personnel.
Once the operation of the regulator has been verified, it can be prepared for patient
use as follows:
1)
Connect the regulator to the wall inlet, ensuring proper latc
hing.
2)
Move the Mode selector to “REG
”.
3)
Occlude the inlet or tubing
.
4)
Adjust the regulator knob to achieve the desired level of
vacuum.
5)
Attach the suction catheter
and proceed.
NOTE: the suction regulato
r should always be turned OFF when not in use. This

882VR Disassembly Instructions
1) Disconnect the 882VR from the suction source
2) Sterilize the suction regulator using ETO or autoclave, for self-protection
3) Remove the four screws on the back of the unit
4) Turn the regulator adjustment knob counterclockwise to release the faceplate
5) The gauge can be gently lifted out of the socket
6) The regulator can be gently lifted out of the socket
7) One screw holds the Mode selector lever in place.
Reassembly is accomplished by performing the above steps in reverse order.

The regulator can be cleaned by wiping the outside surfaces with disinfectants,
Virox (accelerated hydrogen peroxide), Clorox (sodium hypochlorite), and Cavi-
wipes. The internal flow path can be cleaned by suctioning a cold sterilant
through the unit, then allowing the unit to run for 30-45 minutes to dry the
interior.
