11. Carefully cut the nylon cable tie and unplug the
four (yellow, blue, red & black) wire connector (for
the USB connector) from the rear of the upper
PSOC PC board assembly.
12. Unplug the white w/blue strip and white wire
connector 2-wire connector from the Burkert
water regulator/solenoid.
13. Carefully disconnect the clear water tubing from
the plastic barbed fitting on the Burkert water
regulator/solenoid.
14. Carefully cut the flat nylon cable tie at the front of
the Mounting Plate Sub-assembly.
15. Slide the Mounting Plate Sub-assembly forward
and remove it from cabinet housing.
16. Unplug the black and white wires on the Power
Entry Module. Unplug the ground wire from the
center tab on the Power Entry Module.
17. Press the tabs on the four (4) sides of the Power
Entry module to allow it to slide out of the cabinet
housing.
18. Install the replacement Power Entry module in the
opening. The ground prong must face downward.
Ensure the power entry module is fully seated in
the opening.
19. Return chassis assembly to the cabinet housing.
Be sure wires and tubing are not trapped under
the chassis. No wires should be routed under the
Mounting Plate Sub-assembly. The clear water
tube must route directly from the handpiece
receptacle straight back between the raised ridges
on the cabinet housing. Refer to photo.
20. Use three (3) #6 x 1/2” Hi-Lo Torx screws to fasten
the Mounting Plate Sub-assembly to the cabinet
housing and one (1) #6 x 1/2” Hi-Lo Torx screw
and star washer for the ground wire at the water
regulator/solenoid bracket.
21. Attach the clear water tubing from the handpiece
connector to the plastic barb fitting on the
Burkhart water regulator/solenoid. Be sure tubing
is fully seated.
22. Plug the black and white wire terminals with the
toroid coil to the Power Entry Module. The Black
wire goes on the left terminal and the white wire
goes on the right terminal adjacent to the water
regulator/solenoid. The terminals must be fully
seated.
23. Plug the ground wire terminal on the center tab
of the Power Entry Module. The terminal must be
fully seated.
24. Install the Power Switch in the cabinet housing.
The OFF (0) side of the switch must be on the left
side as you face the back of the scaler. Ensure the
switch is fully seated in the opening.
25. Reconnect the terminal wires. The two black wires
should be on the top terminals and the two white
wires should be on the bottom terminals. The
wires with the Toroid should be connected on the
right side. The terminals must be fully seated.
26. Plug the four (yellow, blue, red & black) wire
connector (for the USB connector) from the rear
of the upper PSOC PC board assembly. Use nylon
cable tie to secure wires to corner of PSOC PC
board.
27. Plug the eight (4-white, 2-red, green & black) wire
connector into the front of the lower PSOC PC
board assembly.
28. Plug the four (2-red & 2-black) wire connector into
the front of the power supply PC board assembly.
29. Neatly place the wire harnesses in front of the tab
on the Mounting Plate Sub assembly. Secure the
harnesses with a flat nylon cable tie.
30. On the back of the cover assembly, plug the two-
wire connector into J1 and the 5-wire connector
into J2 from the FPGA PC board. Ensure the two
wire harnesses are tied together with a nylon
cable tie.
31. Align and place cover assembly on the scaler unit.
