Maintenance
Take measures to prevent people from coming into direct contact with
product outlets. Failure to do so may result in burns or other injury from
the discharge of fluids.
CAUTION
Be sure to use only the recommended components when repairing the
product, and NEVER attempt to modify the product in any way. Failure to
observe these precautions may result in damage to the product or burns
or other injury due to malfunction or the discharge of fluids.
CAUTION
Valve Seat Replacement
Replacement of the valve seat with a new valve seat after approximately 100,000 cycles
depending on fluid quality and operation conditions will allow for prolonged use of the
product.
For instructions on valve seat replacement, see the Disassembly/Reassembly section.
Additional Tightening of the Valve Unit Gland Section
It is possible to further tighten the gland section in the valve unit. Where there is leakage
from the gasket or seal, tighten the gland section further using the following instructions:
1. Detach the handle unit (see instructions on p. 8).
2. Tighten, using the following steps:
1) Loosen the holder screw.
2) Tighten the holder further in with a socket wrench.
3) Retighten the holder screw.
Cautions when applying additional tightening:
Do not tighten the holder completely the first time. Do not tighten the holder any
more than is necessary to stop leakage.
If leakage continues even after the holder has been tightened, replace worn parts.
