6.1 Service Tools and Equipment

CAUTION:

 Use of lubricants other than recommended 

may degrade plastic or rubber components.

The following items should be on hand during any service 

procedure.

1.3 kPa) & 80 L/min open air flow minimum

•  Supply Vacuum Regulator with Gauge, 760 mmHg 

(101.3 kPa) Full Scale

•  High Vacuum Calibration Gauge, 760 mmHg (101.3 

kPa) Full Scale*(Ohio Medical P/N 6700-0352-800)

•  80 L/min Flowmeter 
•  Phillips Head Screwdriver, No. 2
•  Flat Head Screwdriver, 1/4 inch
•  Tubing Clamp
•  Bubble Leak Tester
•  Tweezers (Filter Remover)
•  Wooden Tooth Pick (O-ring Remover)
•  Phillips head screwdriver No.1
•  Dow Corning

®

 111 grease (Ohio Medical P/N 6700-

0074-200)

•  Loctite

®

 242 removable thread locker (Ohio Medical 

P/N 0220-5016-300)

•  Stop watch
•  Open end adjustable wrench 
• 

10 L/min flowmeter

(*) Accuracy: ±1% of full scale deflection

6.2 Continuous Vacuum 

      Regulators (All Models)

6.2.1 Disassembly

WARNING: If the Vacuum Regulator is repaired or 

disassembled in any manner, the Service 

Checkout Procedure must be performed 

before using the equipment on a patient.

WARNING: Clean and disinfect all suction equipment 

if contaminated before disassembly to 

ensure service personnel are not exposed to 

hazardous contamination.

WARNING: When servicing a Low Vacuum Regulator, 

perform the Vacuum Relief Valve Adjustment 

and Low Vacuum Limit Setting Procedure.

CAUTION: 

The gauge assembly must be handled with 

utmost care to retain its precision. If the lens is 

removed, do not rest the gauge on its face.

Note: 

 See Section 9.1 Illustrated Parts

1.  Remove the four cover screws from the back of the 

regulator.

2.  With regulator facing up, carefully pull the cover 

assembly off the back body.

3.  To remove the gauge assembly, grasp the assembly 

and pull straight out. The snap-fit lens can also be 

removed (if applicable) for replacement.

4.  Remove actuator and PTS assembly.
5.  To remove the regulator module from the manifold 

assembly, rotate the regulator module clockwise.

6. 

Using tweezers, remove the filter. Replace with a 

 

new filter.

7.  Grasp the positive pressure safety relief valve, and 

pull it from the back body.

8.  Remove the mounting screws from the actuator 

support bracket and remove the support bracket, 

detent plate and selector switch.

9.  Low models ONLY: Grasp the vacuum relief valve  

and pull it from the back body.

6.2.2 Assembly

CAUTION:

 To prevent stripping the plastic threads, place 

the screw in the hole and turn counter-clockwise 

until it drops into the original thread, then tighten  

the screws.

1.  Place the positive pressure safety relief valve in 

position and push onto the back body.

2.  Low models ONLY: Lubricate the vacuum relief valve 

O-ring and install it in the valve housing.

3.  Lubricate switch with a thin coat of Dow Corning 

111 on the overmolded area.  Place in manifold with 

grease side down.

4.  Add detent plate making sure the fingers are on either 

side of the switch shaft and pointing down.

5.  Place O-ring on post coming up through center of 

detent plate and set actuator support bracket over 

O-ring.  Tighten down with 4 screws.

6.  Place cylindrical white filter in corresponding cavity.

7.  Screw regulator module counter-clockwise into 

manifold.

8.  Place PTS assembly in manifold directly below 

regulator module.
