I INITIAL INSPECTION AND HANDLING
On receipt of the unit, note any damage on appropriate shipping documents. File damage claims with the
carrier immediately and NOT with XYLEM WET.
II QUALITY CONTROL
Each RO unit is tested and preserved before shipment to insure quality and performance. This
preservative must be flushed completely from the unit. See the
OPERATION
section of this manual for
the procedures to do so.
III ELECTRICITY
The CAK-139 and NAK-139 BP require 115 volts, 60 Hz, single phase power. The service line should
have a 15 AMP capacity.
NOTE:
220 volt, 50 and 60 Hz units are available as options, motors used on these models are dual
voltage and dual cycle. To verify the electrical specifications, check the “Manufactured By” plate and NOT
the motor plate!
IV INSTALLATION
NOTE:
For long term performance with minimum maintenance, check for the following:
1. That ALL chlorine is removed from the feedwater
2. Hardness is removed from the feedwater
3. Iron is removed from the feedwater
4. Fill out the operator’s log sheet completely and return to XYLEM WET to validate warranty.
NOTE:
Hardness and iron will foul the membranes and result in a decrease in the amount and quality of
the water produced. The membrane’s performance can be restored by a cleaning procedure (contact
your local representative).
NOTE:
If a water softener is used, it should be set to regenerate at night or when the RO unit is not
running.
WARNING:
Chlorine must be removed from the feedwater if present. Chlorine will damage the TFC
membrane and VOID THE WARRANTY. If activated carbon is used to remove chlorine, the carbon
MUST be thoroughly rinsed to remove any small carbon fines before the RO unit is operated.
WARNING:
If this pump driven reverse osmosis system is not installed and maintained according to all
the instructions provided by the manufacturer, and as a result of not following these instructions by the
installer, the water temperature is allowed to exceed 95 degrees F (35 degrees C), then any consequential
damages that result from components on the equipment failing due to any resulting heat stress are not the
responsibility of the manufacturer and are not covered under the manufacturer’s warranty.
