PRE INSTALLATION REFERENCES

Inlet Feed Water - enters through the pre-filter housing. The
housing connection is ¾ "or 1" depending on the model. We
suggest system connections are made preferably with PVC
SCH 80 or SCH 40.
Outlet Product Water - On PRO+RO systems, the permeate
water output exits through the product water flow meter.
through the back of the system.
Outlet Waste Water - On PRO+RO models, waste water or
concentrate exits the reject water flowmeter through the back
of the system.
Control Box Power and Voltage Connections - The PRO-RO-
II and PRO-RO-III are supplied with standard 120 volt, single
phase connections. In situations where the customer specifies
otherwise, there may be changes in this regard. All systems must
be installed in accordance with local regulations.
All PRO+RO Commercial RO Systems use a 120V, single-phase
voltage in the control box and can be converted to
220V. PRO-RO-VIII
models come in
converted to 120V.
Switch and Product Water Level Connections in the Storage
Tank - The cable connections of the liquid level switch are
located directly on the top side of the electrical control box.
The two wires are connected together with the level switch
cables. When the switch is closed, the reverse osmosis system
is switched on. When the switch is open the reverse osmosis
system is switched off.
It is extremely important to make sure you know
!
all regulations pertaining to local, building,
electrical and plumbing parameters of the site
where you are installing the system.

REVERSE OSMOSIS SYSTEM INSTALLATION
INSTALL FOLLOWING THESE STEPS:
1. Choose a place that is covered and has enough space for the
system. The location should also have feed water, electricity and
a specified area for drainage. It is not recommended to install
the system in an area exposed to the elements.
- Start by connecting all water connections to the system
and its pre-treatment.
2. Install the filter inside the housing or make sure it's inside
and PRO-RO-XIV
220V and cannot
the housing.
Recommendations how to insert membranes into the SS housing:
- To insert the membrane in the SS housing it is recommended
to remove the cap from the housing, instead of disconnecting all
the quick connections and tubing.
- When installing the RO membrane, make sure to look at which
direction the arrow is pointing (indicates feed water flow); and
where the brine seal will be located.
- When the arrow is pointing up it is recommended to remove
both housing caps.
- Then remove the brine seal from the membrane and insert the
membrane thru the top of the SS housing (without brine seal).
- Once the membrane reaches the bottom of the housing,
re-insert brine seal on to the membrane. And then, when the
brine seal is in the correct orientation, slide the membrane up
into the housing. Re-install lower and top caps and clamps.
- When installing the membrane with the arrow pointing down,
just remove top cap and clamps.
- Slide membrane down until it seats in the lower cap, in this case
be
no need to remove brine seal. Re-install top cap and clamp.
3. Install the membrane(s) in the membrane housing(s). The
membrane housings have an arrow indicating the direction
of flow. The seal of the membrane should always be
installed in the same direction of the water inlet.
(See diagram below, chapter V of this manual).
4. Open the recycling and rejection valves completely.
5. Make all electrical installations including the storage water
tank level switch. Make sure the system is connected to an
independent designated main breaker.

MEMBRANE INSTALLATION

Membrane seal should always be Installed

in the same direction as the flow of incoming water.
*Note the direction of the membrane seal in the following diagram.
