IMPORTANT
• When measuring the liquid level of the tank,
the minimum liquid level (zero point) must
be set to a level at least 50 mm above the
center of the high pressure side diaphragm
seal (see Figure 4.9).
• Correctly install the diaphragm seal part on
the tank, checking the label “PRESSURE
HIGH” or “PRESSURE LOW” on each seal.
• Exercise care so as not to damage
diaphragm surfaces. For models with
diaphragm seals, since the diaphragm
protrudes approx. 1 mm from the flange
surface, do not place the pressure detector
section face down on a surface as this can
damage the diaphragm.
• Fix the DRS cable in place to keep it from
moving due to wind or vibration. If the DRS
cable is too long, loosely coil the extra tube
portion (coil diameter of 250 mm or more)
and secure the coiled tube with a clamp.
