3. INSTALLATION AND STARTUP
Caution! Electrical installation should only be done by a qualified electrician.
3.1
Rest the unit on a flat level surface capable of supporting its weight (see Table 1). Install
permeate tank next to the unit. Inspect the RO system carefully for damage, including piping, valves
and instruments, pump, pressure vessels, prefilter housings, electrical panel before proceeding
with connection and startup.
3.2
Install membrane in each pressure vessel as follows. Remove the pipes connected to the
pressure vessel ends. Take apart clamp unions or dismantle flange/Victaulic couplings if necessary.
After all adjacent pipes are disconnected and will not get in the way, remove one of the lids of each
pressure vessel. Typically, the lids are held with clamps that must be loosened.
Observe direction of arrow on pressure vessel when installing membrane. Use glycerol
or a similar RO-compatible lubricant as needed. Avoid touching membrane with hands.
Use sterile rubber gloves when handling membrane.
Make a cut in membrane packaging bag and insert membrane in the pressure vessel. The brine
seal ring has to be at the feed end of the vessel. Central tube of the membrane has to mate with
membrane adapter installed at the concentrate end of pressure vessel. If necessary, remove the
opposite lid also for easier insertion of the membrane. Install the lids back in place. Install the
holding clamps back on the lids.
3.3
Connect raw water pipeline from the water main or booster pump. Connect drain and
permeate pipes to the respective connection ports of the RO system. Recommended pipe size is at
least equal to that of the connection port. Use appropriate fittings as necessary. Ensure air gap at
the end of drain line to prevent backsiphonage. Run permeate pipe from the permeate outlet to
the permeate tank and connect using appropriate fittings or glands.
It is strongly recommended to use short runs of pipe or hose the size of which matches
or exceeds that of the connection port.
3.4
Put the float switch inside permeate tank after moving ballast the necessary length up
the cord to provide enough level difference between activated and deactivated position. After the
first filling of the tank, verify that the float switch activates and deactivates in the right positions.
3.5
If the RO system has permeate rinse enabled, install the necessary piping. If using
service interruption by external signal (microswitch), remove jumper from the stop terminals in
the electrical panel. Then, run a cable from the microswitch to the panel and connect to the Stop
terminals. If using antiscalant or other RO chemicals, refer to the dosing pump's instruction manual
for information concerning the dosing pump.
3.6
Run power to the RO system. Connect the phase(s), neutral, and earth conductors as
shown on the electrical diagram. Use a suitable ampacity circuit breaker in your distribution panel.
