Your Thermo Scientific EASYpure® II has been designed with function,
reliability, and safety in mind. It is the user’s responsibility to install it in
conformance with local electrical codes. For safe operation, pay attention
to Notes, Cautions, and Warnings throughout the manual.
This manual contains important operating and safety information. The
user must carefully read and understand the contents of this manual prior
to the use of this equipment.
Water purification technology employs one or more of the following:
chemicals, electrical devices, mercury vapor lamps, steam and heated
vessels. Care should be taken when installing, operating or servicing
Thermo Scientific products. Specific safety notes are listed below.
Warnings
To avoid electrical shock, always:
1. Use a properly grounded electrical outlet of correct voltage and current
handling capacity.
2. Do not locate your EASYpure II directly over equipment that requires
electrical service. Routine maintenance of this unit may involve water
spillage and subsequent electrical shock hazard, if improperly located.
3. Replace fuses only with the same type and rating of fuse.
4. Do not assemble water lines or remove cartridges where spilled water
could contact equipment that requires electrical service. Electrical
shock could result.
5. Disconnect from the power supply prior to maintenance and servicing.

Section 5 Locating the Unit
Place the Thermo Scientific Easypure II on a flat, level bench top that is
accessible to electricity and an atmospherically vented drain, noting the
Clearance Requirements in the General Specifications Section.
For models with UV or UF complete UV, UF and cartridge pack
installation (as described in Installation section) before wall mounting.
Warning Do not locate the Easypure II directly over equipment that
requires electrical service. Routine maintenance of this unit may involve
water spillage and subsequent electrical shock hazard if improperly located.
s
Wall composition, condition 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 150 lbs.
(68kg). Inadequate support and/or fasteners may result in damage to
mounting surface and/or equipment. If unsure of mounting surface
composition, condition and construction or correct fasteners, consult your
building maintenance group or contractor. Please refer to Clearance
Requirements in the General Specifications section.
Install the Easypure II on a wall in a convenient location that is accessible
to an atmospherically vented water drain and electricity.
1. Locate the wall bracket packed separately from the unit.
2. Using the wall bracket as a template, locate and drill the mounting
holes in the wall. A minimum of four (customer-supplied) fasteners
will be required - two on the top and two on the bottom.
3. Attach the wall bracket to the wall using customer-supplied fasteners.
4. Remove the locking screws on each side of the wall bracket.
5. Pull the two locking slides on each side of the wall bracket out as far as
they will go.

the wall bracket slots.
7. Punch the locking slides on each side of the wall bracket in as far as
they will go.
8. Replace the locking screws.
Note If using a reservoir as feed to the EasyPure II, it is important that the
storage reservoir outlet be at the same level or higher than the inlet of the
Easypure II system. s

Section 6 Installation
See Figure 6-1 for details.
1. Disconnect the power cord from the unit.
2. Remove the screws securing the Easypure II top cover.
3. Remove the top cover by lifting straight up.
4. Locate the UV oxidation chamber and pull the top black plastic cover
off. Do not pull on the cable.
5. Remove the UV lamp from its packaging. DO NOT TOUCH THE
GLASS PORTION OF THE LAMP! It is recommended that lint-free
gloves be worn when handling the lamp. The glass portion must be
free of fingerprints, perspiration, etc. Even a light coating of
perspiration will reduce the effectiveness of the lamp. If the glass
portion of the lamp is touched, clean it with a damp, lint-free cloth.
Use isopropyl alcohol as required.
6. Connect the UV lamp to the receptacle in the black plastic cover. Slide
the lamp completely into the chamber and replace the black plastic
cover on the UV Chamber.

7. Make sure the UV lamp cable is tucked behind the chamber before
closing and relatching the door.
8. Reinstall the Easypure II top cover, if installing Ultrafilter on D8611 or
D7411 units do not reinstall cover until Ultrafilter installation is
complete.
Note The UV lamp contains mercury. If broken or no longer needed, do
not dispose of the UV lamp in the trash. Recycle or dispose of the UV
lamp as hazardous waste. s
Caution DO NOT TOUCH THE GLASS PORTION OF THE LAMP!
Even a light coating of perspiration will reduce the effectiveness of the
lamp. s
Refer to Figures 6-2 and 6-3. See Water Connection Details section for
information on push-to-connect fittings.
1. Disconnect the power cord from the unit.
2. Remove the screws securing the EasyPure II top cover.
3. Remove the top cover by lifting straight up.
4. Locate the three tubes with the twist tie around them and remove the
twist tie.
5. Remove the ultrafilter from it’s protective bag.
6. Align the ultrafilter (side ports should face the back of the unit) and
push the bottom fitting tightly
into the bottom connector.
7. Push the top fitting of the
ultrafilter into the top
connector, making sure the
connections are tight.
8. Secure the ultrafilter with the
strap. Side ports will be facing
the back of the unit.
Note The ultrafilter comes
complete with fittings installed. s
