SAFETY
Your Cole-Parmer washer offers the following safety features:
OVERFILL PROTECTION — In the unlikely event that a
malfunction overfills the chamber, an overflow float sensor device
activates chamber draining.
DOOR SWITCH — The unit is equipped with a door switch that
automatically pauses the washer if the door is opened during a
cycle. The wash cycle will continue from the point of interruption
after the door is re-closed.
SAFETY CATCH — The washer is fitted with a safety catch
that, when engaged, prevents unintentional door opening and the
resulting risk of injury from exposure to hot water or steam. When
engaged, opening the door requires two hands. See Section 5,
“Washer Components.”
To ensure safe operation, please follow these recommendations:
• Read all instructions carefully before using the washer.
• This glassware washer must be properly grounded. See
Section 4, “Installing the Washer.”
• Use only detergents and neutralizers recommended by Cole-
Parmer for use in glassware washers. Heikol products have
been specifically formulated for use in Cole-Parmer washers.
• Before opening the door, always wait for the sounds of
rotating spray arms and circulating water to stop.
• Do not wash plastic items unless they are marked “washer
safe.” Check with the item’s manufacturer if unmarked.
• Remove the door before discarding an old washer.
WARNING:
If this equipment is used in a manner not specified in this manual,
safety protections designed into the equipment may be impaired.
Only qualified service personnel should remove cabinet panels.

WASHER OVERVIEW
This section describes washer capabilities and the sequence of
phases composing wash cycles.
Through available control settings, your washer offers a variety of
different operation cycles—permitting you to design the cycle best
suited for your application.
In Main Wash and Heated Rinse phases, an in-line heater element
heats water to a programmed temperature.
1
You can use the HW
(HIGH-HEAT WASH) and HR (HIGH-HEAT RINSE) buttons
to maximize operating water temperatures.
Cycles then proceed through the following sequence of (possible)
phases:
On some program cycles, not all of these phases are utilized.
Table 3-1 on page 6 lists the phases for each program type.
PRE-WASHES — In Pre-Wash phases the chamber sump well
fills with tap water and then the circulation pump activates to wet
down the load from the rotating spray arms and (on spindle-rack-
equipped CLW-128i units) from the spindles. Pre-Wash phases
may be heated or unheated (depending on the cycle selected).
They conclude by draining all water from the chamber.
MAIN WASH — The chamber fills with tap water, which is heated
to the temperature called for by the selected program and option-
button settings. At the start of the Main Wash phase, the detergent
compartment cover hinges open to introduce detergent. The load is
bathed with recirculating heated water. The Main Wash phase
concludes by draining all water from the chamber.
1
Heated-Phase durations are determined by the cycle program selected and the required water heat-up time.
Therefore, total cycle time is influenced by the source-water temperature and operator control selections.

RINSES — Depending upon the cycle selected, up to two tap water
rinses and up to two DI water rinses may follow the Main Wash
phase. Table 3-1 on page 6 lists the phases for each program type.
During each rinse phase, water fills the chamber and then circulates
over the load. The terminal DI Water Rinse phase (on cycles having
this phase) is heated to the temperature called for by the selected
program and option-button settings. If neutralizer is loaded, it is
delivered into the chamber during rinse phases as described in
Table 3-1. Rinsing concludes by draining all water from the chamber.
DRYING — During the Drying phase, a fan blower circulates
and vents chamber air to speed drying.
Overall time to complete a cycle varies depending upon the cycle
selected, selected control panel functions, and the facility’s water
temperature. Although not required, hot source water speeds water
heat-up, decreasing cycle time.
To learn about washer components and controls, please refer to
Section 5, “Washer Components,” on page 15.
For step-by-step operating instructions, jump ahead to Section 6,
“How to Run a Wash Cycle,” on page 23.
For installation instructions, go to Section 4, “Installing the
Washer,” on page 7.

INSTALLING THE WASHER
Your Cole-Parmer glassware washer must be enclosed on the top,
back, and both sides. The cabinet enclosure into which
Undercounter units are installed supplies this protection.
Freestanding / Mobile units are equipped with a #3 stainless steel
cabinet.
Only qualified, factory-trained personnel familiar with local plumbing
and electrical codes and ordinances should install the washer. For a
first-time installation, all site preparation work must be completed
before the washer can be installed with final utility connections. If
the new washer replaces an existing unit, verify that all plumbing
and electrical connections are properly sized and located.
To protect floor surfaces, Undercounter
units are supplied with leg slides for
attachment to washer feet. These decrease
friction as the unit is moved across the floor.
Preparing for Installation
REQUIRED TOOLS
• Phillips #2 screwdriver
• Flat blade screwdriver
• Adjustable wrenches
• 5/8" (16 mm) open-end wrench
• Tape measure
• Spirit level
• Electric drill
• Hole-saw bits up to 2" (50 mm) diameter
REQUIRED PLUMBING SUPPLIES
Your unit is supplied with two rear-mounted barbed fittings for
connection to your facility’s tap water and DI water supplies.
Two 6' lengths of 1/4" ID x 3/8" OD flexible tubing are provided.
Mating extension hoses are available in a Facility Installation Kit
(Part Number 445490). We recommend installing a shutoff valve
at the water supply connection. You will also need an appropriate
fitting for connecting the supplied drain hose to your drain system.

Step-by-Step Installation Instructions
1) PREPARE THE TAP AND DI WATER CONNECTIONS
Plan the fitting connections and the route for water supply tubing
from the washer to your water supplies. On Undercounter units,
drill appropriately sized cabinet entry holes as required, keeping
within the shaded area pictured in the previous section. With the
washer outside of the cabinet recess, feed the water supply tubing
through the cabinet hole(s) toward the water source connectors.
For DI water connection, use plastic or stainless fittings. Brass
fittings corrode in contact with DI water and are not recommended.
2)
PREPARE THE ELECTRICAL CONNECTION
For convenience, the unit is provided with a pre-wired electrical
cable and plug. Locate or install a code-conforming electrical
receptacle within reach of the washer’s supplied cable. The
electrical supply should be a dedicated circuit that is properly
grounded and breaker-equipped.
Drill an appropriately sized cabinet entry hole within the shaded
area pictured on page 9.
WARNINGS:
1) The electrical receptacle must be properly
grounded and must comply with applicable
portions of all national and local electrical
codes.
2) All washer servicing should occur with the
power cord disconnected from power.

11
No other appliance or outlets should share this circuit. Provide a
local disconnect or switch to ensure safe maintenance access.
With the washer still outside of the cabinet recess, feed the power
cord through the cabinet hole toward the AC outlet.
3)
CONNECT TO THE FACILITY DRAIN
The unit is supplied with a drain hose oriented over a rear-mounted
“high-loop” saddle. To prevent problems with drainage, backflow,
and siphoning, the high-loop configuration must be preserved—
typically by an arrangement similar to the following (shown here
for an Undercounter model):
Fashion a drain connection that conforms to these requirements:
• No part of the drain hose should exceed 35" (90 cm) above
the bottom of the washer.
• The drain connection must be at least 20" (50 cm) above
the bottom of the washer.
• The drain hose extends no more than 10' (3 m).
• Any joints or fittings must be 3/4" (18 mm) ID or larger.
• The drain hose is not directly connected to a floor well or
its equivalent—this could cause a siphon that empties the
machine during cycles. The drain line should never be
connected to a check valve.
• Do not route the washer drain through a vent or air gap, as
this may impede flow during some drain phases. If the drain
cannot be hard piped as shown above, locate the drain hose
over an open counter drain or floor drain instead.
Drill an appropriately sized cabinet entry hole as required to reach
the drain connection. Feed the supplied drain hose through the
(HOSE ORIENTATION
WITH UNIT IN PLACE)

Cole-Parmer CLW-108i & CLW-128i Washers
12
cabinet hole toward the drain connection, then connect the drain
hose to your drain.
4)
CONNECT THE TAP AND DI WATER SUPPLIES
Connect and tighten all water connections securely.
5) CONNECT THE ELECTRICAL SUPPLY
For a Freestanding / Mobile unit, roll the washer into its final
location and connect the supplied power cord to an appropriate
receptacle. Secure the unit by depressing the caster brake levers on
the unit’s casters. After circuit power is activated, the washer is
ready to operate.
For an Undercounter unit, connect the unit’s AC power plug to its
AC receptacle.
6) TEST FOR LEAKS
Before final leveling and securement in position, test for leaks as
follows:
a. Turn ON the electrical power and water supplies.
b. Push the door closed until it is securely latched.
c. Follow the “How to Start a Cycle” procedure on page 24
to select and operate a LIGHT cycle. This cycle executes
both tap water and DI water rinses.
d. While the cycle is operating, carefully check all water
supply and drain connections to ensure that there are no
leaks. Correct any observed leaks.
7)
MOVE THE UNIT INTO FINAL POSITION
Using an assistant if necessary to take up excess cable and hose
slack, push the washer fully into its final position.

_____________________________________________________________________________
Cole-Parmer CLW-108i & CLW-128i Washers

8) ADJUST THE LEVELING LEGS
On Undercounter units, leg height may be adjusted as follows:
Use a 5/8" (16 mm) wrench to adjust leveling legs to the required
height and to level the unit. Any inclination must be ≤2°. Use the
locking nut to lock your adjustments:
If rear-leg height adjustment is necessary, temporarily remove the
washer from final position to adjust the rear leg.
9) SECURE THE WASHER IN ITS FINAL POSITION
Undercounter Units:
To prevent forward
tilting when downward
force is applied to the
open door or when
heavily loaded baskets
are pulled outward, use
screws to fasten the washer to the cabinet. Using the supplied
screws, plastic spacers, and rubber cosmetic plugs, secure the
washer to the cabinet using alternative “A” or “B” (one screw on
each side) as shown here.
Freestanding / Mobile Units: If your application creates the
potential for forward tilting, use the supplied TIP GUARDS or
your own fashioned brackets to secure the washer’s rear castors
to the wall or floor. Typical installations are shown here:

If you prefer to fix the Freestanding / Mobile washer in a
permanent location, leveling feet are provided to replace the
castors.
10) TOE-KICK PLATE INSTALLATION (OPTIONAL)
On Undercounter Units, the supplied TOE-KICK PLATE can be
attached to the washer’s lower front to optimize appearance. You may
decide that attaching this plate is unnecessary for your installation.
To attach the TOE-KICK PLATE, position each of the two PLATE
SUPPORT BRACKETS inward or outward to the desired depth
(pulling its catch inward to release the bracket). Then, simply hook
the TOE-KICK PLATE onto the front of the bracket.
