Safety Information
Your Barnstead EASYpure RO has been designed
with function, reliability, and safety in mind. It is
your responsibility to install it in conformance with
local electrical codes. For safe operation, please
pay attention to the alert signals throughout the
manual.
Warnings
To avoid electrical shock, always:
1. Use a properly grounded electrical outlet
of correct voltage and current handling
capacity.
2. Do not mount the EASYpure RO directly
over equipment that requires electrical
service. Routine maintenance of this unit
may involve water spillage and subse-
quent electrical shock hazard if improperly
located.
3. Replace fuses with those of the same type
and rating.
4. Disconnect from the power supply prior to
maintenance and servicing.
To avoid personal injury:
Warning
Warnings alert you to a
possibility of personal injury.
Caution

SAFETY INFORMATION
1. Do not use in the presence of flammable or
combustible materials; fire or explosion may
result. This device contains components
which may ignite such materials.
2. Ensure all piping connections are tight to
avoid leakage of chemicals.
3. Ensure adequate ventilation when using
chemicals for cleaning.
4. Follow carefully the manufacturers’ safety
instructions on labels of chemical containers
and Material Safety Data Sheets (M.S.D.S.).
5. Refer servicing to qualified personnel.
C. To ensure safe mounting:
1. Wall composition and construction, as well
as fastener type, must be considered when
mounting this unit. The mounting surface
and fasteners selected must be capable of
supporting a minimum of 120 lbs.; inade-
quate support and/or fasteners may result in
damage to mounting surface and/or equip-
ment. If you are unsure of mounting surface
composition, condition and construction, or
correct fasteners, consult your building
maintenance group or contractor.

Unpacking
Carefully remove the unit from its shipping contain-
er.
The following items are shipped separately and
must be removed from the packaging prior to dis-
carding the packaging:
1. EASYpure RO Ventgard air filter.
2. Power cord.
3. Pump interlock cord.
4. Membrane bypass tubing.
The following items are located inside the mem-
brane access door:
1. Feedwater tubing.
2. Reject water tubing.
3. Product tubing to connect accessory
reservoir.
4. Product tubing to connect another
EASYpure unit.

Locating your EASYpure RO
Your EASYpure RO must be located within six feet
of an electrical outlet appropriate for your unit, with-
in five feet of your feedwater supply and close to
an atmospherically vented drain. If you are using
the accessory 30 Liter Reservoir (Part Number
TY742X2A), the tank overflow on the EASYpure
RO's integral 6.5 liter tank should be located below
the level of the storage reservoir's overflow. This
will ensure that the EASYpure RO's internal float
switches will control the operation of the system. If
the EASYpure RO is to be used with the accesso-
ry 30 Liter Reservoir, the reservoir must not be
mounted farther than 4 feet away from the
EASYpure RO. The EASYpure RO Bench Stand
(Part Number D7424) will be required for a bench
mounted installation with an accessory 30 Liter
Reservoir.
General usage
Do not use this product for anything other than its
intended usage.
Do not mount the EASYpure
RO directly over equipment
that requires electrical ser-
vice. Routine maintenance of
this unit may involve water
spillage and subsequent
electrical shock hazard if
improperly located.

INSTALLATION
Bench Mounting
If you are bench mounting the EASYpure
RO without the accessory 30 Liter Reservoir
(Part Number TY742X2A), simply place the
EASYpure RO on a bench.
If you are bench mounting the EASYpure
RO and using it in conjunction with the
accessory 30 Liter Reservoir (Part Number
TY742X2A), the EASYpure RO Bench Stand
(Part Number D7424) must be added to the
EASYpure RO to ensure automatic opera-
tion. Install the EASYpure RO Bench Stand
as follows:
1. Remove the 4 feet from the
EASYpure RO and retain the
screws.
2. Place the EASYpure RO on the
Bench Stand so that the screw
holes where the feet were attached
line up with the holes in the Bench
Stand.
3. Install the 4 screws removed in
step 1 through the bottom of the
Bench Stand and into the
EASYpure RO.
4. Install the accessory 30 Liter
Reservoir according to the instruc-
tions in the accessory 30 Liter
Reservoir manual.
