Care and Cleaning (Cont.)
To minimize odor and avoid sediment build-up in the trapway, it is
important to flush out your waterless urinal every two weeks. Please
follow the .Required Bi-Monthly Flush-out Cleaning. procedure below.
Required Bi-Monthly Flush-Out Cleaning
Repeat the daily cleaning procedure.
Using a small screwdriver or bent wire, carefully lift the strainer
vertically from the drain. Clean the strainer and set it aside.
Quickly pour one gallon of water directly into the drain. Do not let the
urinal overflow. This will purge the residual urine and sealing liquid.
Unscrew the spray nozzle from the cleaner bottle. Pour 1 oz. (30 ml) or
2 tablespoons of cleaner directly into the drain.
Allow the cleaner to stand for 5 to 10 minutes.
Pour two gallons of water directly into the drain as quickly
as possible. Do not let the urinal overflow.
Pour 3 oz. (90 ml) or approximately 1/3 cup of sealing liquid directly
into the drain.
Reinstall the strainer.
IMPORTANT! Failure to perform bi-monthly flush-out cleaning may
eventually result in a clogged urinal. If the urinal becomes clogged,
a plunger, urinal auger, or non-Kohler brand strong acid cleaner may be
used. If a non-Kohler brand strong acid cleaner is used, thoroughly rinse
the urinal with water after application to minimize acid corrosion on the
seal gasket and downstream piping.
Winterizing the Urinal
Repeat the daily and flush-out cleaning procedures, but do not replace
the sealing liquid after the flush-out.
NOTE: Use recreational-use antifreeze only. Recreational-use antifreeze
is specifically formulated for winterizing all types of potable water
supply systems, preventing rust, and protecting metal pipes.
Pour recreational-use antifreeze directly into the drain.
Reinstall the strainer.
IMPORTANT! Before using the urinal again, remove the strainer and
flush out the antifreeze with 1 gallon (3.79 liters) of water. Pour 3 oz.
(90 ml) or approximately 1/3 cup of sealing liquid directly into the drain,
then reinstall the strainer. The urinal is now ready for use.
