III. OPERATION
A. INSTALLATION
1.
The water supply should be sufficient to provide a minimum of 20 psig pressure at the
design
feed flow.
2. Proper pretreatment must be determined and installed prior to the RO system.
3. A fused high voltage disconnect switch located within 10 feet of the unit is
recommended. This disconnect is not provided with the RO system.
4. Responsibility for meeting local electrical and plumbing codes lies with the owner /
operator.
5. Install indoors in an area protected from freezing. Space allowances for the removal of
the membranes from the pressure vessels should be provided. This system requires 42"
minimum clear space on each side.
B. PLUMBING CONNECTIONS
Note: It is the responsibility of the end user to ensure that the installation is done according to
local codes and regulations.
1.
Connect the pretreated feed water line to the inlet side of the prefilter housing. (Figure #
1 item # 1) A feed water shutoff valve should be located within 10 feet of the system.
2. Temporarily connect the outlet of the product water flow meter to drain. (Figure # 1 item
# 2) The product water line should never be restricted. Membrane and/or system damage
may occur if the product line is blocked.
3. Connect the outlet of the reject water flow meter to a drain. (Figure # 1 item # 3) The
reject drain line should never be restricted. Membrane and/or system damage may occur
if the reject drain line is blocked. An air gap must be located between the end of the drain
line and the drain. The use of a standpipe or other open drain satisfies most state and local
codes and allows for visual inspection and sampling.
C. ELECTRICAL
Note: It is the responsibility of the end user to ensure that the installation is done according to
local codes and regulations.
1.
A safety switch or fused disconnect should be installed within 10 feet of the system.
2. Verify that the disconnect switch is de-energized using a voltmeter.
3. Connect the outlet of the disconnect switch to the terminals on the motor starter (Figure #
2, or 3). Attach the power supply ground to the chassis ground. It will be necessary to
drill a hole in the enclosure and install a water tight strain relief or conduit connector.
The hole size and location must be determined by the installer. Check the pump motor
nameplate for the amperage draw at various voltages to determine the wire size required.
