INSTALL FILTER SCREEN (included):
Note: Place lter in stop bore with conical screen facing the water ow.
Caution: Do not push lter in too far. Let lter seat against face of ush valve tail. Periodic cleaning of the lter screen with water is
recommended depending on local water conditions to remove any dirt or sediment. See lter screen M&I for additional installation
information.
FLUSH BOTH OLD AND NEW PIPES:
It is important to FLUSH and CLEAN thoroughly both old and new water piping to ELIMINATE contaminants (eg. scale, sediment, gravel,
cuttings, solder, etc.) from the line. Where the water has a sediment content, a PIPE STRAINER in the supply line should alleviate that
condition and protect working parts of ushometers and faucets. On a NEW INSTALLATION, always ush the valve 4 or 5 times to clean out
supply line debris. It is also advisable where more than one ushometer is installed on a water line, to ush out the water piping through the
last ushometer outlet of the pipe line.
ELIMINATE AIR FROM VALVES:
The FIRST FLUSH should ELIMINATE all air from the TECK ushometer.
DO NOT ADJUST ushometer based on the results of the rst ush.
TO PREVENT WATER HAMMER:
A capped-pipe vertical AIR CHAMBER may be installed at the last ushometer and/or at the back of an individual installation. This assures
SMOOTHER OPERATION of the valves and longer life for the working parts.
FLUSH VOLUME ADJUSTMENT:
1.60 U.S. gallons/6.0 litres for water closets
0.5 U.S. gallons/1.9 litres for urinal valves
The Regulating Screw (061024A, item #8a) may be adjusted according to job
conditions and xture installed, to the proper water volume to ush that particular xture
(except -6, -42, -48, -19 and -05 models which are not eld adjustable).
NOTE: 4.2, 4.8 and 6 litre water closets or washdown urinals may require the Inlet Stop
to be set at only one turn open.
For a SHORTER ush, turn Regulating Screw (061024A, item #8a) left (counter-
clockwise) and right (clockwise) for a LONGER ush (except -6, -42, -48, -19 and -05
models which are not eld adjustable).
RECOMMENDED WATER SUPPLY:
W/C - minimum owing pressure: 25 psi (172 kPa), minimum ow rate: 25 gpm (95 lpm)
UR - minimum owing pressure: 25 psi (172 kPa), minimum ow rate: 8 gpm (30 lpm)
