MDM AS SUPPLIED WITH CONVENTIONAL RUBBER GOODS The following assembly procedure is common for all MDM models supplied with conventional rubber goods (see fig 1): 1. Position breathing bag as shown and slide opening in breathing bag over outside diameter of bag mount.
Page 6
MDM AS SUPPLIED WITH NITROUS OXIDE - OXYGEN SCAVENGER The following assembly procedure is common for all MDM models supplied with the dental scavenger (see fig 2): 1. Position breathing bag as shown and slide opening in breathing bag over outside diameter of bag mount.

The following mounting adaptations, method of assembly, and installation are for all MATRX Analgesia Heads. For Top Mounting Wall Mounted Units (see fig 3) 1. Remove the two 10-32 x ¼” screws from the rear, top of the head, and assemble the mounting bracket to the rear top of the analgesia head by aligning the bracket with the bevel side to the head and the 10-32 tapped holes in the head with the screw holes in the bracket.

A. Wood Stud Mounting Note: Mounting hardware is not supplied with the mount. Using a minimum wood screw size of #12 x 2 ½” long and flat washer #12 x 5/8” minimum outside diameter, mount the wall bracket directly to a wood wall stud through a maximum 5/8” dry-wall. Two screws are required for each mounting (see fig 4).

A. Thread hex nut onto mounting stud until at least ¾” of thread is exposed above nut on stud. (See fig 11). B. Thread stud into 5/8 - 18 tapped hole located on bottom of the outlet housing of the analgesia head.
CONNECTION AND ACTIVATION OF GAS SUPPLY TO MACHINE...
Page 11
Hoses are not supplied as standard equipment with analgesia heads, except for portable units, and must be ordered separately, specifying hose length. Gas connections to the Matrx analgesia heads are accomplished by using color-coded and mechanically indexed hose assemblies. CAUTION 1.
1. Connect DISS female hexagon fitting (see fig 18) of the nitrous oxide hose to male DISS fitting on the back of the analgesia head (see fig 19). Accomplish this connection by screwing female hexagon fitting onto male threaded fitting. Tighten to hand tight and then finish tighten with 7/8 open end wrench just enough to prevent leaks.

Nitrous Oxide cylinders are blue. Oxygen cylinders are green. Pin index system is a method of pins accurately located on the face of the cylinder yoke and holes accurately located on the cylinder shut-off valve, such that only cylinders of a specific gas will fit the cylinder yoke for that specific gas.
Page 14
NOTE This cylinder mounting procedure will be typical for either nitrous oxide or oxygen cylinders. CAUTION Do not attempt to assemble nitrous oxide cylinder to oxygen yoke or oxygen cylinder to nitrous oxide yoke. Do not remove pins from yoke assembly. ...
NOTE Close the valve stem when the cylinder is not in use. This completes the assembly of the analgesia unit. SPECIFICATIONS A. Standard MDM Flowmeter Heads (See fig 26)

PRE-OPERATION A. Rotate flow control valve fully counter-clockwise (See fig 30). Rotate mixture dial to 100% position.
Page 21
B. Connect hoses to gas source as outlined in Figure 19 and 22 of the Description and Mechanical Assembly section. C. Activate gas source. NOTE For initial start up of analgesia head, always have a medical gas source shut-off. For multiple outlet station manifold systems utilizing quick-connect fittings, the analgesia unit can be moved from station to station without shutting off the medical gas source once pre-operation and functional tests are completed.

Turn on gas cylinders by rotating the valve stem on the cylinder counter-clockwise slowly two full rotations. Use customer-supplied cylinder wrench or use wrench available through your MATRX by Parker dealer. b. Examine reading on pressure gauges located on regulators. For a full tank of oxygen, the pressure should be about 2000 PSIG.
Install supply cylinder into “E” cylinder mount and open cylinder valve slowly. Remove acorn nut from the end of regulator (second stage) and install 3/16” hex key into now exposed set screw. Adjust flow control at flowmeter head to approximately 3 LPM. Adjust 3/16”...

All gas cylinders are chained to the wall. All primary oxygen gauges read pressure. All secondary oxygen gauges read 50 to 55 PSIG All nitrous oxide gauges read O. D. Test for crossed gas lines by connecting an indexed gas hose on each outlet station in each area connected to the system and: ...
1. Has a common cold 2. Has tuberculosis or other pulmonary conditions 3. Has been undergoing psychiatric treatment 4. Has multiple sclerosis References: Langa, H. (1968) “Relative Analgesia in Dental Practice” - W.B. Sanders Company Parbrook, G.D. (1968) “Therapeutic Uses of Nitrous Oxide” - British Journal of Anesthesia 40K 365 This list does not include all possible contraindications.
Adjust mixture dial to 50% oxygen position. Adjust flow control until Oxygen and Nitrous Oxide flowmeter tubes show approximately 5 LPM each gas. Without further adjustment of flow control knob and a total of 10 LPM, move mixture dial through full travel.
4. Nitrous Oxide and Oxygen Flowmeters - the amount of gas flowing is indicated by reading the position of the midpoint (maximum diameter) of the ball. (See fig 32). B. Set the Mixture Control to 100% Oxygen. C. Set the Oxygen Flow Rate to Equal Total Gas Flow to be administered to the patient. D.
C. For cleaning the outside of the machine and accessories, we recommend the use of a germicide containing glutaraldehyde. Follow the manufacturer’s directions for use. SERVICE All service and repair must be accomplished at Matrx by Parker. Have your dealer return the unit to our factory and arrange for a loaner unit for yourself. CE Notice symbol on this product indicates compliance with the Medical Device Directive of the European Community.
