Specifications

25InRow RP CW Installation
Humidifier
The humidifier water supply line is routed to the unit in flexible tubing (or alternative
tubing approved by local building codes) that will allow the humidifier water supply
line connector to be moved approximately 25 mm (1 in) away from the equipment.
This facilitates removing the equipment from a row.
A factory-installed quick-connector for connecting the tubing to the equipment is
supplied. See “Install kit inventory” on page 5. The quick connector has a male 1/4-in
NPT or male-1/4 in BSPT to connect to a compression fitting. The quick-connector
has a shut-off function, so no separate shut-off valve is necessary.
The humidifier water supply line
can be connected through either
the top or the bottom of the
equipment as shown. Male
quick-connectors are positioned in
both the top and the bottom of the
equipment.
Water pressure should be between
100 and 800 kPa (15 and 115 psi)
for proper humidifier operation.
Dirty water must be filtered
before it is supplied to the
humidifier. Water temperature
must be between 1ºC and 40
°C (34ºF and 104°F). Do not use softened, de-mineralized, or de-ionized
water.
See the manual included with the humidifier for more information about water quality,
mineral content, hardness, and minimum/maximum levels for conductivity.
Note: It is recommended that a solenoid water valve be installed in the humidifier supply line,
connected to a leak detector.
Note: Perform all piping in accordance with applicable industry guidelines as well as local and
national codes and regulations.
Connect the fittings to the humidifier water supply line as shown, then connect the
water supply line quick-connector to the top or bottom humidifier input.
