Use and Care Manual

COUPLER REPAIR (4059)

1. Using 8 inch Vice Grips clamp the top ribbed or knurled portion of the Coupler; then using a 17 mm Open End

Wrench on the lower part of the Coupler twist counter clockwise to loosen.

2. Remove top of Coupler, Rubber Seal, Cone Spring, and keep Valve for reinstallation. Remove Spring from collared

portion of the Coupler using a pointed tool. The two pieces will then come apart. Remove any debris that may be in the

Coupler.

3. Using a Coupler Repair Kit (4059) replace Ball Bearings and then the Spring (making sure the Spring is inserted all

the way.) Then return Valve, and replace Cone Spring and Rubber Seal, and then thread top portion of the Coupler

back to the lower portion and tighten. Without inserting the the Brass Plug (10038) into the Coupler run the Pump with

water to ensure Coupler does not leak. If Coupler leaks, disassemble and reseat the Valve and Rubber Washer, then

test again. NOTE: The Valve and Rubber Washer placement is critical to ensure Coupler does not leak.

REPLACING DRAIN TUBE (#10159)

Note: If there is a leak at the Drain it needs to be determined if the leak is between the Drain Tube (10159) and the

Drain Cartridge (18015), or the Drain Cartridge and the Solution Tank (18009). If the leak is between the Drain Tube

and the Drain Cartridge the Drain Cartridge should not be removed from the Solution Tank.

1. Remove Door (10606). Using #2 Philips Screwdriver remove (4) 10-24 Bolts (#10150) attaching Door to Solution

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.
