Water supply line; water pressure must be
between 25 psi and 80 psi (175 kPa and
550 kPa); water conductivity minimum
100 μS/cm. If water piping to humidifier is
nonmetallic, we recommend that the first
3' (1 m) of water supply piping from the
humidifier be metallic
Steam vapor hose; may also use
pipe or tubing. See Table 16-1
for maximum piping lengths
