EASYpure II RF 2-1Thermo Scientific

Section 2 Introduction

The Thermo Scientific EASYpure II RF is a batch-fed water purification
system designed to provide Type I reagent-grade water with extremely low
organic carbon content. It uses a three-stage deionization process combined
with a 0.2 micron final filter to polish pretreated water (distilled,
deionized, or reverse osmosis) to produce water with a resistivity of up to

18.2 megohms-cm and with a total organic carbon content of less than 10
ppb. Water resistivity is continuously sensed by a resistivity cell and
displayed on a digital display.

The EASYpure II RF is designed to be a bench mounted unit. If wall
mounting is required, contact Technical Services for information on a wall
bracket and mounting accessory.

Section 6 Controls

The power switch on the EASYpure II RF is located on the back right side
of the unit directly above the power cord receptacle.

The EASYpure II RF control panel incorporates three switches and a
digital display.

When the main power switch is on, the three switches on the control panel
function as follows:

• START: Pressing the START switch when the unit is in either the stop
(“IdL”) or standby (“SbY”) mode will put the unit into run mode.

• STANDBY: Pressing the STANDBY switch when the unit is in either
the start (run) or stop (“IdL”) mode will put the unit into a standby
mode.

• STOP: Pressing the STOP switch when the unit is in either the start
(run) or standby (“SbY”) mode will put the unit into a stop (“IdL”)
mode.

Note On initial power-up, the display will run the following sequence:

- Model type is scrolled -RF

- The display’s LEDs will light up,

- Followed by the unit software revision,

- Finally, IdL will be displayed.

Add

Note On initial start-up, the purity meter may display “Er.1”. This is
caused by air in the cell and should soon be replaced by a resistivity
reading. If “Er.1” does not go out after the pump has run for a minute. or
if it appears any time while the EASYpure II RF is in operation, refer to
the Troubleshooting section of this manual.

s

Note When the unit is first put in Run Mode, the display will show 10.0
for a few seconds. This is an arbitrary number that indicates the unit is
running. Any number that appears after 10.0 indicates purity.

s

Note If the unit is in standby and power to the unit is turned off or lost,
the unit will return to standby once power is restored.

s

Note Do not put unit into Idle Mode or turn off the EASYpure II RF
during non-work hours. Doing so will allow bacterial growth and other
contamination of the water in the system. As a result, the system will
require a lengthy rinse-up period at the beginning of the work day to
achieve high-quality product water.

s

Since not all qualities of permissible feedwater will reach maximum
resistivity after one pass through the unit’s cartridges (especially as the
cartridges near exhaustion), the EASYpure II RF has two operational
modes; run and standby.

In Run Mode, the pump continuously recirculates water through the
cartridges. It is recommended that the EASYpure II RF be left in the run
mode during the day. In Run Mode, the purity meter display indicates the
resistivity of the water available for draw off. Allow the water’s resistivity to
rise to the desired purity before drawing off water.

In STANDBY (“SbY”) mode, the pump will restart for ten minutes out of
every hour (i.e 50 minutes off, 10 minutes on). The display reads “rEC”
which indicates recirculation. This will allow the unit to produce high
quality water quickly upon being placed in Run Mode. It is recommended
that the EASYpure II RF be placed in Standby Mode during non-work
hours. At the end of the work day, press the STANDBY switch on the
front of the EASYpure II RF to place the unit in STANDBY mode for the
night. “SbY” will appear on the display.

“IdL” indicates the unit is powered and waiting to be placed in Run or
STANDBY mode.

Section 7 Initial Operation

Note Cartridge rinse up procedure must be followed after each cartridge

and/or filter replacement.

s

Note In the event that the feedwater reservoir is overfilled, allow the excess
water to drain from the reservoir through the overflow drain tubing before
replacing the Ventgard cap. This will prevent wetting the filter element.

s

Warning Use a properly grounded electrical outlet of correct voltage and
current handling capacity.

s

Warning This device is to be used with water feeds only. Sanitizing/
cleaning agents must be used in compliance with instructions in this
manual. Failure to comply could result in explosion and personal injury.

s

Normal Operation

Feedwater

Replenishment

As water is drawn off from the EASYpure II RF, the feedwater reservoir
will require refilling. This will be indicated by a low water level in the sight
gauge or by the message “Add” on the display. To refill the reservoir:

1. Remove the Ventgard cap. Do not allow water to enter the Ventgard
cap.

2. Carefully pour pretreated feedwater into the feedwater reservoir until
the water is level with the top of the sight gauge. Replace the Ventgard
cap.

3. Allow the water’s resistivity to rise to the desired purity before drawing
off water.

Section 9 Maintenance and Servicing

Frequency of cleaning is difficult to determine because of variability in
feedwater and usage. Cleaning is necessary when residual deposits are
evident inside the feedwater reservoir or if a new 0.2 micron final filter
clogs rapidly after installation even though the cartridges were properly
rinsed before the 0.2 micron final filter was installed. To sanitize the
EASYpure II RF, remove the 0.2 micron final filter and attach the hose
barb that came installed on the unit. The purification cartridges must be
removed and replaced with empty cartridges. These must be ordered
separately. Contact Technical Services to order.

Warning Disconnect from the power supply prior to maintenance and
servicing.

Do not disassemble water lines or remove cartridges where spilled water
could contact equipment that requires electrical service. Electrical shock
hazard could result.

Refer servicing to qualified personnel.

s

Note Drain plug is not attached to unit; use care when removing it over an
open drain to avoid dropping it into the drain.

s

Note The cartridges will still contain water when removed. Therefore, you
will want to have a sink, bucket or other waterproof container available to
place them in after removal.

s

Note A small amount of water will drain from the cartridge when it is
disconnected from the lower socket. Plug the cartridge’s lower opening
with your finger to minimize water spillage while you finish removing the

Section 11 Replacement Parts

Consumable parts are those required to support the day-to-day operation
of this equipment. We’ve established two types of consumables; those items
that must periodically be replaced to maintain performance (filters, resin
cartridges, etc.) and other items of limited life (indicator lights, fuses, etc.)
that you can expect to replace on a more or less random basis. Where
practical, we recommend the frequency of replacement, or provides
information on life expectancy from which you may calculate a
replacement interval compatible with your usage pattern.

The replacement of consumable parts is discussed in the Maintenance and
Servicing section to assist you in accomplishing your own service.

Consumables may be ordered separately and in some cases, as an
expendables kit. Check with your Thermo Scientific representative for
additional information on the expendables kit.
