MONTHLY CHECK 

Leak test the entire system for working 
pressure leaks.

Connect an 8060 series duplex 

connector and hoses into the Triple Outlet Station.  
Attach the other end of the hoses to a flowmeter and
turn the flow control knobs to the off position and the 
on/off switch to the off position. 
Pressurize the sedation gas supply lines with 50 PSI. 
Observe any pressure decay after 12 hours.  This 50 
PSI test with the flowmeter tubing connections in 
place tests the seal of the duplex connector extended
into the o-rings of the outlet station primary check 
valves. (5 PSI drop allowed.)

PRIMARY CHECK VALVE 

DISASSEMBLY INSTRUCTIONS 

SERVICE PRIMARY CHECK VALVE  

May be serviced with station pressurized to 
50 PSI. 

1.

Remove front plate.  Mounting screws are behind
plate labels.

2. Unscrew the primary check valve assembly.

Oxygen right hand threads; Nitrous Oxide left
hand threads

.

Note:  the secondary check

valve will move into position and seal the
50 PSI of the station pressure as the
primary check valve assembly is
removed.

WARNING

Do not remove the cartridge body
while servicing the primary check
valve assembly.  The secondary
check valve cannot seal the 50 PSI 
pressure if the cartridge body is 
removed. 

3.

Replace the entire assembly.

4.

Screw the replaced assembly into the cartridge
body.

5.

Alignment & Adjustment for Front Plate
Installation – The Oxygen and Nitrous Oxide
Valve Bodies are factory adjusted to allow for the
back of the Front Plate to press against the metal
surfaces of all three valve bodies.  If adjustment
is needed, follow these steps:
5.1.  Rotate the Oxygen and Nitrous Oxide valve

bodies so they both uniformly contact the 
back of the Front Plate. Oxygen has right 
hand threads and Nitrous Oxide has left 
hand threads.

5.2.  Adjust the right hand thread vacuum valve 

body to align with the metal surfaces of the 
other valve bodies.   

6.

Leak test the entire system for working
pressure leaks per the Monthly Check.

SECONDARY CHECK VALVE 

DISASSEMBLY INSTRUCTIONS 

SERVICE SECONDARY CHECK VALVE 

WARNING

To service the secondary check valve, first turn off pressure.  Do not remove the 
cartridge body until the pressure is bled off.  The secondary check valve cannot 
seal the 50 PSI pressure if the cartridge body is removed. 

1.

Turn off pressure at tanks in tank room.

2.

Follow procedure to remove primary check valve assembly.

3.

Depress secondary check valve further into station block using a small probe or screw driver to bleed off
pressure.

4.

Unscrew cartridge body out of the station block.

5.

Take a small screw driver or needle nose pliers and insert into holes at the center of secondary check valve.
Carefully remove check valve and spring.

6.

Replace the 016 o-ring and secondary check valve parts as required and place in position for reassembly.

7.

Screw in the cartridge body and tighten.

8.

Screw in the primary check valve assembly and align and adjust for front plate installation.

9.

Leak test the entire system for working pressure leaks per the Monthly Check.

TRIPLE OUTLET STATION 

INSTALLATION AND INSTRUCTIONS 

The Porter Triple Outlet Station (6256-3) provides a 
quick, safe, and reliable method of connection to both
Porter Sedation and Clean-Air™ outlet service.  The 
6256-3 provides all the service features of the Porter 
6200-1 N

2

O/O

2

outlet station, and the Porter 5600-3 

Clean-Air outlet station.  Features include the 

cross+protection 

system to prevent unintentional 

misconnection to the central piping system.  The 
outlet station utilizes a duplex connector which 
prevents the Nitrous Oxide from being connected 
unless the Oxygen is connected, and offers 
resuscitator quick connect compatibility.  Compact 
stainless steel face plate is color coded for instant 
gas identification.  A qualified plumber should install 
the outlet. 

STATION INSTALLATION INSTRUCTIONS 

1.

LOCATION

:

Select appropriate location for

mounting station to a stud prior to installing
drywall or wall board.  Secure bracket “A” to stud.
(Fig. 1)

WARNING

Porter Instrument Outlet Stations utilize the 

cross+protection 

system. The copper tubing is

diameter indexed; 3/8” O.D. for Nitrous Oxide and ½” 
for Oxygen. The 

cross+protection 

system is 

designed to prevent misconnection of Oxygen and 
Nitrous Oxide piping.  

DO NOT ATTEMPT TO 

CHANGE THE DIAMETERS!  

Tampering with the 

cross+protection

 system constitutes acceptance of

liability by the installer.  For your own protection, as 
well as that of the Doctor and the patients, use 3/8”
O.D. tubing for all Nitrous Oxide lines and ½” O.D. 
tubing for all Oxygen lines.  

To assure safe operation and conformation to local 
fire codes, all Porter Instrument Outlet Stations are 
designed to be used with sedation delivery systems 
mounted inside walls and they meet or exceed the 
guidelines established by the National Fire Protection
Association for Nonflammable Medical Gas Systems, 
NFPA 99. Copies of NFPA 99 or portions thereof may 
be obtained by writing to: 

National Fire Protection Association 
Batterymarch Park
Quincy, MA 02269-9904 
Or call: 1-800-344-3555 

WARNING

 Dental workers are exposed to N

administration of N

conscious sedation 

analgesia.  NIOSH has recommended that exposures
should be minimized.  Contact NIOSH (1-800-35-
NIOSH) to receive NIOSH Publications on 

Control of 

Nitrous Oxide in Dental Operatories.  

Exposure can 

be minimized by effective controls.  National Institute 
for Occupational Safety and Health (NIOSH) 
publications state that controls, including System 
Maintenance, Ventilation and Work Practices can 
effectively reduce N

O concentrations in dental 

operations.  Your Porter Scavenger System is an 
important part of the system of controls.
