6. Loosen the hex nut using a 3/8 inch socket. If
recessed area is too small to allow the socket to
fit, use needle nose pliers.

9. Install the new cable.
10. Connect the new cable (knurled nut end) to the RPM4
(see Figure 5). Secure it by manually tightening
finger tight.
11. Remove the hex nut and washer from the heat-
shrinked connector, (see Figure 4) insert the
connector through the E-DWT housing, and secure
it to the outside of the housing using the washer and
hex nut that was just removed. The washer should
be installed on the outside of the housing directly
under the nut. It is recommended to use Loctite
222MS or similar on the nut to help ensure it does
not come loose.
12. Reposition the E-DWT on the table in its normal
upright position.
13. Replace the variable volume handle that was
removed (see Figure 2).
14. Connect Adapter to end of power supply cable.
15. Connect new power supply and open vent on
reservoir for normal operation (see Figure 1).
16. Test functionality to ensure there are no problems
with the cable installation or power supply.
17. Dispose of old cable and old power supply.
