Attention installer
Read this manual before installing, and leave this manual with product owner. This product must be installed by qualified
HVAC and electrical contractors. Installation must be code approved.
Disconnect electrical power
Disconnect electrical power before installing supply wiring or performing service or maintenance procedures on any part
of the system. Failure to disconnect electrical power could result in fire, electrical shock, and other hazardous conditions.
These hazardous conditions could cause property damage, personal injury, or death.
CAUTION
Operate system at above-freezing temperatures.
Operating the system at temperatures below freezing can damage the system or cause other property damage.
Maintain pumping and water treatment equipment.
Inadequately maintained pumping and water treatment equipment can cause the system to fail. Refer to the maintenance section
of this IOM for recommended maintenance.
Do not install the system using steel or galvanized-steel piping and joints.
Steel and steel-galvanized piping and joints can corrode and cause system damage. Use plastic tubing and joints when
assembling system.
Follow all instructions in this manual to maintain product warranty.

System specifications
OVERVIEW
NOTES:
1. All systems rated at 50°F (10°C) using 1000 ppm sodium chloride (NaCl)
solution. System capacity decreased significantly with decrease in feed
water temperature.
2. Chlorine requirements for the feed water are:
a. Thin-Film (standard) 0 ppm
3. Feed water must be filtered to a turbidity of less than 1 NTU.
4. System recovery (permeate to concentrate ratio) must be maintained at
the recommended level. A higher than recommended recovery will lead
to a premature fouling of the membrane with a loss of permeate flow and
permeate quality.

DRISTEEM WATER TREATMENT SYSTEMS INSTALLATION, OPERATION, AND MAINTENANCE MANUAL
INSTALLATION
System installation
1. Locate RO system with adequate clearance from walls and other
equipment to enable membrane servicing.
2. Run five polyvinyl tube lines to the system as follows:
LINE 1
Connect raw water feed supply to the solenoid valve inlet in front of the first
cartridge filter housing. This will require ½ inch threaded pipe fitting and
adaptor for the feed line. If desired, install an isolation valve in this line; ensure
the valve opening does not restrict the water flow.
LINE 2
Run a ⅜inch line from the open end of the concentrate valve to a drain. Ensure
that no liquids from other lines near this drain flow back through this line.
LINE 3
Run a ⅜inch line from one of the two permeate outlets on the back of the
system to the pressurized permeate storage container.
NOTE: The recirc flow line is pre-connected at the factory.
LINE 4
Run a ⅜inch line from the other permeate outlet to the humidifier or end
process being fed by the system.
LINE 5
Run a ¼inch line from the pressurized relief solenoid to a drain. Ensure that no
liquids from other lines near this drain flow back through this line.
FIGURE 5-1: SOLENOID VALVE INLET
FIGURE 5-2: RECIRC FLOW LINE
CAUTION
Pump and system performance will be
adversely affected if the feed/suction
line is restricted.
CAUTION
Confirm all lines are connected before
plugging in unit power.

6DRISTEEM WATER TREATMENT SYSTEMS INSTALLATION, OPERATION, AND MAINTENANCE MANUAL........
PRE-TREATMENT CONNECTION
If you have pre-treatment equipment and you wish to shut-down the RO system
during backwash or regeneration, a microswitch is required (standard with
DriSteem water softeners).
1. Wire the microswitch to terminal labeled PreTreat inside controller.
When the equipment goes into backwash or regeneration, the pre-treat limit
switch opens and turns the power off the inlet solenoid valve, which then turns
the RO pump off (and back on) when the cycle is complete.
