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.
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 valve. (Figure # 1 item I) 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
G) 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 F) 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.
Make sure the on off switch located on the controller is in the off position.
2. Wire the input power supply to the bottom of the contactor inside the controller. (See
drawing in the appendix.) Make sure the voltage selector jumpers match the voltage you
are suppling.
