Pre-Installation Information
Check Rough-In location PRIOR to installation
Flush lines thoroughly PRIOR to hook-up
When installing the Willoughby Industries' WWF-3603 Series washfountain system:
Before Step 1 of the installation instructions, ensure that rough-ins are in the correct location.
The valve assembly, including the spray head, MUST NOT BE connected until after
all lines have been fl ushed to remove the small particles of debris that are inherent
with new construction projects and all chemicals that are used in fl ushing are purged
from the system.
Chemicals used in fl ushing plumbing systems can attack the internal components of
the valve and spray head and severely damage them, so any fl ushing of the system
must be followed by a full fl ushing with pure water to clear any harsh chemicals
remaining in the system. Debris in the system if allowed to enter the valve assembly
and spray head can cause poor performance or outright failure.
Again DO NOT attempt to connect the valve assembly and spray head until after all
fl ushing is complete and pure water is the only media that will be passing through the
system. Damage to the valve assembly or spray head caused by harsh chemicals or
debris will not be covered by the manufacturer's warranty.
Check Rough-In location PRIOR to installation
Flush lines thoroughly PRIOR to hook-up
