IMPORTANT SAFETY INSTRUCTIONS.

READ AND UNDERSTAND THESE INSTRUCTIONS

COMPLETELY BEFORE OPERATING THIS

EQUIPMENT.

If you do not understand any of these instructions, or if you have any

questions regarding the use of this product, please contact your

facility’s training manager, your supervisor, the medical equipment

dealer from whom the product was purchased, or the manufacturer

before operating the equipment.

Do not attempt to repair this device if you have not been properly

trained. Doing so may create a hazardous situation that may result in

death or serious injury. Attempted repair by anyone other than a duly

authorized repair/service center of Genstar Technologies Co., Inc. voids

any and all warranties, express or implied.

Carefully inspect and test this product before each use to ensure proper

operation. Do not use the product if there are signs of damage or if it

does not pass the initial suction test.

Should this product require repair or service that will require shipping

the product to another location, bear in mind that United States

Federal law prohibits shipping contaminated products, as they

constitute a biohazard. This product must be properly sterilized and

securely packaged prior to shipping.

Genstar Technologies Co., Inc. (GENTEC®) manufactures continuous suction

regulators in two ranges, 0 to 300mmHg (882VR-300) and 0 to 760mmHg (882VR-

760). These suction regulators provide three modes: REG (regulated vacuum), OFF

(no vacuum) and FULL (whatever is available at the wall inlet). Please take a few

minutes to familiarize yourself with the product by reviewing Figure 1 on the next

page.

The mode is selected by moving the lever at the top of the regulator to the left

(REG) for regulated suction, the center (OFF) to turn off the regulator, or the right

(FULL) to allow full line suction.

The REG mode provides regulated suction levels as set by the user. The suction

level is set by occluding the suction tubing, then adjusting the regulator knob on

the front of the suction regulator to achieve the desired suction level, up to the

designed range. Suction is increased by turning the regulator knob clockwise,

decreased by turning it counter-clockwise.

The OFF mode turns off the suction regulator, allowing no suction at the tubing.

The FULL mode bypasses the regulator, and is designed for use only when high

levels of suction are needed. Care should be exercised when using this setting, as

the patient will be exposed to whatever level of suction is available at the wall inlet

(typically above 480mmHg).

A suction filter or vacuum trap assembly (GENTEC catalog #880VT) should be

used to prevent aspirate from entering the suction regulator. Typically, the suction

catheter is connected to the suction tubing, which is then connected to the inlet

fitting on the suction canister.

The canister can be connected directly to the suction regulator via DISS

connection, or, as is recommended, connected to a filter or vacuum trap, which is

then connected to the suction regulator via direct, threaded connection, suction

tubing, or DISS connector (see Figure 2).

The appropriate outlet connector (located on the back of the suction regulator)

must be used for connection to the wall inlet. The use of converting adapters (e.g.,

DISS connection to Ohio connection) should be avoided. If the suction regulator is

connected via tubing or hose assembly to the wall inlet (as occurs when the

suction regulator is attached to a mobile stand), a minimum inside hose diameter

(ID) of 5/16” (7.9mm) should be used to prevent loss of flow.

DO NOT connect the suction tubing directly from the patient to either the

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) position.

2) Connect the regulator to a vacuum source (normally the wall-mounted inlet).

3) Occlude the regulator inlet, and turn the adjustment knob one full turn

clockwise.

4) Verify that the gauge needle does not move from the “0” position.

5) Move the Mode selector to the “REG” position.

6) Occlude the regulator inlet, and turn the adjustment knob counter-clockwise

until the gauge needle is at 0.

7) Keeping the inlet occluded, turn the adjustment knob one full turn clockwise.

The gauge should read between 120 and 170 mmHg.

8) Keeping the inlet occluded, turn the adjustment knob fully clockwise. The

gauge needle should move clockwise to the highest vacuum setting.

9) Move the Mode selector to the “FULL” position.

10) Occlude the regulator inlet. The gauge needle should move to the highest

vacuum setting.

11) Turning the adjustment knob should have no effect on the gauge reading when

the selector knob 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 latching.

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 regulator 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.
