When installing the Willoughby Industries’ WH-1900 / 1950 Patient Care Units:
Before Step 1 of the Installation Instructions, ensure that rough-ins are in the
correct location.
It is essential that the water supply lines be thoroughly ushed prior to making
nal connection to the hot and cold water supply lines. These lines must be ushed
sufciently to remove the small particles of debris that are inherent with new con-
struction projects.
If this debris is not removed, the valving in these units will be damaged. Do not
attempt to remove the aerators to ush debris out of the lavatory. The damage can
only be xed by replacing the valves. Damage to valves caused by debris will not
be covered by the manufacturer’s warranty.

Solid Surface Care
Aquasurf® surfaces may be easily cleaned using conventional cleaning agents such as an ammonia
based liquid cleaner, (glass cleaner).
Dry stains on a matte nish can be removed with a 3M Scotch-Brite gray scouring pad or a mild
abrasive cleaner.
Burns or scorches can be removed by sanding with coarse grit sandpaper followed by ner grit
(220) sandpaper. Follow sanding with a 3M Scotch-Brite gray pad (or equivalent) to match nish of
sanding area to surrounding area. A nal bufng may be required on polished surfaces. Accidental
nicks or chips can be repaired with special patch kits available in all Aquasurf® colors.
Avoid exposing Aquasurf® surfaces to strong chemicals such as acetone’s; paint removers
and sulfuric acid or hydrochloric chemical cleaners. Exposure to strong chemicals may result in
permanent damage to Aquasurf® surfaces.
Stainless Steel Care
Stainless Steels are basically alloys of iron and chromium and are corrosion resistant. Stainless
steel has a bright surface that is easy to clean and is free from oxides. Therefore, cleaning of
stainless steel is relatively simple and easy if done on a regular basis.
Frequency of cleaning should depend on the rate at which the xture becomes dirty. Remember
that fresh (soft) deposits of all kinds are relatively easy to remove, while removing older (hard)
deposits are much more difcult. Establish a cleaning SCHEDULE.
Routine cleaning should involve ordinary soap or detergent and water, applied with a sponge,
brush or cloth. Baking soda, borax or any of several non-abrasive commercial cleansing agents
can help hasten the cleaning action. After scrubbing, rinse THOROUGHLY and wipe dry.
DO NOT use common steel wool, scouring pads, scrapers, wire brushes, les or other steel tools to
clean stainless steel. Such items will scratch the surface or leave small particles of iron imbedded
in the surface, which will eventually rust and stain the surface - even appearing as if the stainless
itself was rusting.
Certain chemical compounds, if used on stainless steel, can give the appearance of rust and if
allowed to stand for long periods of time, can pit the surface of even stainless. Products containing
hydrochloric acid, muriatic acid or potassium hydrochloride can ruin the surface.
