2) To stop water flow
Pushing up PULL ROD allows VALVE (A) to close, so the water stops flowing from
SHOWER HEAD.
1-2. To Operate Eyewash
1) To flow water
Turning the PUSH PLATE or Stepping on to Foot Pedal
allows VALVE (B), so the water flows instantly from FLOW HEADS.
2) To stop water flow
Turning the PUSH PLATE back to the original position
allows VALVE (B) to close,so the water stops flowing from FLOW HEADS.
1-3. Scald Protection Valve
Scald Protection Valve is installed to the unit for scald protection.
A rise in temperature causes the valve to open.
The valve closes when the fluid temperature drops, below the preset temperature.
Opening Temperature: 40.6 deg-C(105 deg-F)
Closing Temperature: 35.0 deg-C(95 deg-F)

operating pressure requires
to be at a minimum of
0.207 MPaG.
Water flow from shower
head looks lower than
