Tank.
2. Remove the O-Ring (10430) from between the Drain Cartridge (18015) chrome flange and brass base. Push in on
chrome flange ring on the Drain Cartridge (18015). While pushing in the flange pull Drain Tube (10159) at the same
time. The Drain Tube (10159) will release from the Drain Cartridge (18015).
3. If there is a leak between the Drain Cartridge (18015) and the Solution Tank (18020) remove the Drain Cartridge
from the Solution Tank by inserting a 5/16" Allen Wrench all the way into the opening of the Drain Cartridge. Turn the
Allen Wrench (Clockwise to Counterclockwise) to unthread the Drain Cartridge from the Solution Tank. Clean the Drain
Cartridge and Solution Tank threads and apply a good amount of Teflon Tape to the Drain Cartridge threads. Reinstall
the Drain Cartridge being extra careful not to cross thread the Solution Tank threads, start the threading by hand before
using the wrench.
4. Remove the Drain Insert (18204) and Drain Spring (10429) from the Drain Tube (10159). Cut about 1" off the end of
the Drain Tube that was installed in the Drain Cartridge or replace the Drain Tube. Slide the Drain Insert (18204) onto a
Small Screwdriver, flange towards handle. Then slide the Drain Spring (10429) onto the screwdriver. Insert the Drain
Spring and Drain Insert into Drain Tube (10159) using the screwdriver. Put a new O-ring (10430) on Drain Tube, insert
Drain Hose Assembly into Drain Cartridge (18015). Push in hard until brass insert is all the way in the Drain Cartridge.
5. Slide the O-ring (10430) in between chrome flange and brass base of Drain Cartridge, using a little hook tool and 1/8
flat screwdriver.
TESTING LID (7LIDLM)
1. Make sure all Switches (10308 / 18032) are turned OFF. Plug in the machine. Make sure Bucket (10604) is in place
and the Lid (7LIDLM) is secured by the Bucket Bail (10086). Disconnect the Grey and Black Vacuum Cuffs (10075 /
10077).
2) Turn on the suction and slowly vacuum water from an 8 oz. glass through the Grey Cuff. Water should appear in the
right Sight Tube. The left Sight Tube should be dry. If water appears in the left Sight Tube, the Lid may need to be
replaced or returned to Kent Investment Inc. for remanufacturing.
