Turn shut-off valve on and check for leaks. If connections
are squarely assembled, a slight retightening of the nuts
will stop any leaks.
If toilet is leaking in between the tank and bowl, carefully
retighten the three tank bolts evenly. Check all bowl and
tank connections for leaks for several days.
OPERATION NOTES:
The long handle actuates the 1.6 gallon flush for
typical solid waste removal.
The short handle actuates the 1.1 gallon flush for
light waste and liquid waste.
Flush the toilet twice, once with 1.6 gallon flush handle
and once with 1.1 gallon flush handle. Compare the
flushing action between the two flushes. The 1.6 gallon
flush should be similar to the 1.1 gallon flush except
extended in time and flush action. Fig. #9
FLUSH MECHANISM
NOTE: Be sure the 1.1 gallon (short) and 1.6 gallon
(long) flush chains are attached to the correct arms and
cam locations. See the illustration at right.
