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 5 Installation
1. Place the EASYpure II RF on a bench top convenient to your work
area, noting the Clearance Requirements. If wall mounting is required
contact Technical Services.
2. Using 1/2" I.D. tubing and tubing connectors (user supplied), connect
the overflow drain tubing (lower left corner of the rear of the unit) to
an atmospherically vented sink or floor drain. If an atmospherically
vented sink or floor drain is not accessible, a bucket or other container
may be placed on the floor beneath the EASYpure II RF’s location and
emptied when full.
Warning Do not place EASYpure II RF directly over equipment requiring
electrical service. Routine maintenance of this unit may involve water
spillage and subsequent electrical shock hazard if improperly located. s
Warning 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.
Warning This device is to be used with water feeds only. Sanitizing/
cleaning agents must be used in compliance with instructions in this

Section 5
Installation
Refer to Figure 5-3 for the procedure below.
1. Open cartridge access door in the rear of the unit by pushing the door
latch down.
2. Remove a new Pretreatment cartridge from its plastic bag.
3. Wet the o-rings with water on both end caps.
4. Press the upper end cap into the pretreatment position until it bottoms
out.
5. Lower the cartridge and insert the lower end cap \into the lower socket
until it is firmly seated.
6. Repeat Steps 2 - 5 with the Ultrapure cartridge and then the EASYpure
High Purity/Low TOC or Ultrapure cartridge, placing them in
positions 2 and 3.
7. Close cartridge access door. This serves to verify the cartridges have
been properly seated.
Note The upper end cap is the one with the right-angle turn and the two
flanges. The lower end cap extends straight out from the cartridge.
Note The two flanges on the end cap should be able to slide down on each
side of the keyway wall.
Cartridge Installation
Figure 5-3. Cartridge Installation

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.

In addition to displaying the temperature compensated (25°C) resistivity in

indicators. The following is what can appear on the display:

IdL Er5
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.
