roller will not compress the tube properly. A "frozen"

roller, which does not turn on its shaft will abrade the

tube and cause premature tube failure.

Tube:

The pump tube should be replaced after 500

hours or 3 months storage. Before discarding, the tube

should be examined for abrasions and cuts. These con-

ditions can indicate wearing or malfunction of moving

parts.

Pump Tube Replacement

Please follow these steps for removal and replace-

ment of pump tubing in the DrizAir 120 Dehumidifier.

Inspect and replace tubing every 500 hours of opera-

tion.

1. Disconnect the power to the unit.

2. Open the front compartment door.

3. Disconnect the suction and discharge hoses from

the pump tube.

4. Unscrew the screws that hold the front plate of the

pump in place. Remove the front plate. The other

screws that attach the pump housing to the motor

base do not need to be removed.

5. Remove the used tubing in a "U" shaped pattern

clockwise, starting from the top left side. Discon-

nect the tube from the hose fittings.

6. Clean the roller race, removing any articles that

could damage tubing. Check the rollers for loose-

ness or binding. The rollers must fit snugly on the

shaft and spin freely. See the Troubleshooting sec-

tion for guidelines if a problem exists.

7. Insert the new tube into the inlet port, anchoring

the tube in grippers. As you insert the tube, rotate

the rollers clockwise so that the rollers follow the

tube as it is being inserted.

8. Continue to rotate the roller bracket assembly,

pushing the tube into the roller race.

9. Insert the tube into the outer port.

10. After complete installation of tube, ensure that

there is no excess tubing and that all slack is taken

up to avoid excessive wear. Re-check all connec-

tions and fittings.

11. Replace the front plate and secure with the four

screws. Run the pump to ensure correct operation.

When a new tube is installed there is an initial

break-in period before the tube "softens".
