Mounting Bracket and Connector Installation
3. Install the hanger bracket onto the rear of the Multi-Operatory Accessory using
the Phillips head screws provided in the accessory kit, as shown in Figure 2.
4. Ensure the Mach 5/5+ is turned off. Remove the Mach 5/5+ remote from its
mount if it is mounted on the air abrasion unit, and unplug the inter-connecting
cable.
5. Disconnect the existing footswitch from the Mach 5/5+.
6. Install the connectors for the existing Mach 5/5+ footswitch and remote onto the
Multi-Operatory Accessory, grouping the connectors on either side (but the same
side) as shown in Figure 2. Use the 20 foot cables supplied with the Multi-
Operatory Accessory for both remotes.
NOTE: The footswitch supplied with the Mach 5/5+ must be installed in the
operatory which has the shortest run between the operatory and the Mach 5/5+
system, a total of up to 12 feet (limited by the footswitch). If a longer footswitch
cable is needed, refer to section 5 for optional parts and accessories.
7. Install the connectors for the second operatory footswitch and remote onto the
Multi-Operatory unit, grouping the connectors on the remaining side as shown in
Figure 2.
8. Install the power cable from the power supply unit onto the power supply
connector located on the bottom of the Multi-Operatory unit.
9. Install the 1 ½ inch long interconnect tube by screwing the brass fitting into the air
manifold located on the top of the Multi-Operatory unit. Ensure this fitting is air
tight. Hand tightening should be adequate.
10. Pull the accessory tray located at the top of the Mach 5/5+ unit out several
inches, and place the hanger bracket, with the Multi-Operatory unit, over the front
of the accessory tray. Gently move the unit back with the accessory tray, until the
protruding male air fitting is aligned with the female air fitting located on the front
of the Mach 5/5+. Push the unit back until the air fitting locks securely into the
Mach 5/5+ system. If there is any difficulty, ensure all traces of abrasive powder
are removed from the Mach 5/5+ air fitting by blowing the powder from the
connector with compressed air.
11. Remove the thumbscrews (4) from the black pinch tube covers located on the top
of the unit, and remove the black covers. Install a pinch tube over each of the
fittings on the ends of the provided 20 ft long air/abrasive handpiece tubes. Install
