Installation, Operation

and Maintenance Manual

Commercial Reverse Osmosis Systems

Series PWR4022

CAUTION: Please read the entire manual before proceed-

ing with the installation and startup. Your failure to follow any

attached instructions or operating parameters may lead to the

product’s failure, which can cause property damage and/or

personal injury.

• Do not use where the water is microbiologically unsafe.

• Pretreatment must be sufficient to eliminate chemicals that

would attack the membrane materials.

• Always turn off the unit, shut off the feed water, and discon-

nect the electrical power when working on the unit.

• Never allow the pump to run dry.

• Never start the pump with the reject valve closed.

• Never allow the unit to freeze or operate with a feed water

temperature above 100°F.

Save manual for future reference.

Please refer to Section 6 of this manual for operating parameters

according to your speciﬁc feed water Silt Density Index (SDI). For all

other settings according to your speciﬁc feed water quality, please

contact your Watts representative. A chemical analysis of the feed

water should be conducted prior to the initial sizing and selection of

this system.

Notes

Changes in operating variables are beyond the control of Watts. The

end user is responsible for the safe operation of this equipment.

The suitability of the product water for any speciﬁc application is the

responsibility of the end user.

Successful long-term performance of an RO system depends on

proper operation and maintenance of the system. This includes

the initial system startup and operational startups and shutdowns.

Prevention of fouling or scaling of the membranes is not only a mat-

ter of system design, but also a matter of proper operation. Record

keeping and data normalization are required in order to know the

actual system performance and to enable corrective measures when

necessary. Complete and accurate records are also required in case

of a system performance warranty claim.

Changes in the operating parameters of an RO system can be

caused by changes in the feed water or can be a sign of trouble.

Maintaining an operation and maintenance log is crucial in diagnos-

ing and preventing system problems. For your reference, a typical log

sheet is included in this manual.

Note: Do not use with water that is microbiologically unsafe or

of unknown quality without adequate disinfection before or after

the system.
