Installation and Startup
Initial Inspection
Your VWR glassware washer was carefully packed and thoroughly inspected before
leaving the factory. However, in the unlikely event that shipping damage has occurred,
retain all packing material and contact your freight carrier immediately.
DO NOT ACCEPT damaged shipments from a carrier without a signed notification of
damages.
Upon receiving your shipment, inspect all contents of your equipment for damage.
Check packing material for small accessory items. Remove all packing material
carefully and inspect for concealed shipping damage. Inspect the inside of the
machine for any visible damage. If concealed damage or loss is discovered, contact
the freight carrier immediately.2 Keep all contents, packing material and related
paperwork intact until a written report is obtained.
Note: VWR International will cooperate in the matter of collecting your claim, but is not
responsible for the collection or free replacement of the material. When possible, replacement
parts will be shipped and invoiced to you, making them a part of your claim.
2 “Concealed damage or loss” refers to damage or loss that does not become apparent until the merchandise has been
unpacked and inspected. Should damage or loss be discovered, you may make a written request for inspection by the carrier's
agent within 15 days of the delivery date. You may then file a claim with the freight carrier or VWR International, depending on
the terms of your shipment. If your shipment was “FOB Destination” file your claim with VWR International and include the
inspection report and any other supporting documents. If your shipment was “FOB Shipping Point” file your claim with the
freight carrier and include the inspection report and any other supporting documents.

Service Connections
PROPERTY CAUTION! ONLY QUALIFIED 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.
The service connections that you intend to use must meet the following requirements:
Requirement Specification
Tap Water Supply
(All Models)
 Minimum Flow Requirement:
3 gpm (11 lpm) @ 18 – 60 psig (124 – 414 kPa)
 Although not required, hot water speeds water heat-up and decreases
cycle time. Hot water supply must not exceed 60 °C (140 °F)
Deionized Water Supply
(All Models Except H-1105)
 Minimum Flow Requirement:
3 gpm (11 lpm) @ 18 - 60 psig (124 - 414 kPa)
 Resistivity  1 M/cm
 Although not required, installing a shutoff valve (not supplied) in the
water supply line at a readily accessible location will help facilitate
service of the unit.
Electrical Requirements
(All Models)
 120 VAC, 1, 60 Hz, 15 A.
 Installation Overvoltage Category II.
 Main supply voltage fluctuations not to exceed ±10% of normal voltage.
Environmental Conditions
 This product is intended for indoor use in the following
environmental conditions:
 Altitudes up to 6500 ft (2000 m)
 Temperatures from 5 to 40 °C (41 to 104 °F)
 Maximum relative humidity of 80% for temperatures up to 31 °C (88 °F),
decreasing linearly to 50% relative humidity at 40 °C (104 °F).
Required Plumbing Supplies
Your unit is supplied with rear-mounted PEX plastic hose with 3/8-inch brass
compression fittings3 for connection to your facility’s tap and DI water supplies (if
applicable). Various hose and compression adaptors will be provided for additional
water and plumbing needs. It is recommended that you install a shutoff valve at the
water supply connection. An appropriate fitting for connecting the supplied drain hose
to the drain system is also required.
3 Model UCW-VA00001 uses a compression fitting.

Dimensional Requirements
For all units, allow at least 26.5 inches of clearance in front of the unit for door
extension and at least two (2) inches of clearance on each side of the door. Prepare
an installation space or cabinet recess consistent with these and the other dimensions
as specified for your model.
Recommended cabinet recess dimensions for undercounter washers are shown
below.
Undercounter Washer Site Preparation
During undercounter washer installation, ensure that the water and electrical services
enter the cabinet recess within the shaded area shown below.
2 to 3-1/2”
(50-90 mm)
7 to 9”
(180-230 mm)

Water Connections
Plan the fitting connections and the route for water supply tubing from the washer to
your water supplies. Drill appropriately sized cabinet entry holes as required, keeping
within the shaded area pictured on the previous page. With the washer outside of the
cabinet recess, feed the water supply tubing through the cabinet hole(s) toward the
water source connectors. Route the unit’s drain hose toward a connection to your
facility’s main drain, but do not make any connections at this time.
For units requiring a DI water connection, use plastic or stainless fittings. Brass fittings
may corrode from DI water and are therefore not recommended.
Electrical Connection
WARNING! THE ELECTRICAL RECEPTACLE MUST BE PROPERLY GROUNDED AND COMPLY
WITH APPLICABLE PORTIONS OF NATIONAL AND LOCAL ELECTRICAL CODES. ALL WASHER
SERVICING SHOULD OCCUR WITH THE POWER CORD DISCONNECTED FROM POWER.
For convenience, the unit is provided with a prewired 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 equipped with an appropriately-sized breaker.
Drill a cabinet entry hole for the power cable. Refer to the image below:
Your VWR glassware washer should not share a circuit with any other appliances.
Provide a local disconnect or switch to ensure safe maintenance access.
Freestanding Washer Site Preparation
For freestanding units, ensure that the water and electrical service connections have
sufficient slack. Excessive tension in water hoses strains fitting connections and can
cause host leakage and/or breakage.
Position the unit on a firm, level floor. Follow the instructions in the Washer Setup
section of this chapter to level and secure the unit.

Approximate Rear Connection Locations
Note: Your unit may vary from the
image shown, depending on the
model.
Washer Setup
Your VWR glassware washer must be enclosed on the top and back, and on both
sides. The cabinet enclosure into which undercounter units are installed supplies this
protection. Freestanding and mobile units are wrapped with stainless steel panels.
To install your VWR glassware washer:
1. Connect the washer drain hose to your facility’s main drain, ensuring that the
“high-loop” configuration is preserved (as shown below).
The drain connection must conform to the following requirements:
 No part of the drain hose should exceed 35 inches (90 cm) above
the bottom of the washer.

 The drain connection must be at least 20 inches (50 cm) above the
bottom of the washer.
 The drain hose should extend no more than 10 feet (3 m).
 Any joints or fittings must be 3/4-inch (18 mm) ID or larger.
 Do not connect the drain hose directly to a floor well or its
equivalent as this could cause a siphoning action that could empty
the machine during cycles. Never connect the drain line 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, secure the drain hose over an open counter drain or floor
drain instead.
PRACTICAL OPERATING TIP. DRILL AN APPROPRIATELY SIZED CABINET ENTRY HOLE AS
REQUIRED TO REACH THE DRAIN CONNECTION. FEED THE SUPPLIED DRAIN HOSE
THROUGH THE CABINET HOLE TOWARD THE DRAIN CONNECTION AND CONNECT THE
DRAIN HOSE TO YOUR DRAIN.
2. Connect the washer to a tap water supply and tighten all connections
securely. If your unit is equipped with a DI water connection, connect the DI
water supply and tighten all connections securely.
3. Connect the unit to the appropriate electrical supply.
4. Test the unit for leaks before leveling and securing the washer in place.
To test for leaks:
 Turn on the electrical power and water supplies.
 Close and secure the door.
 Select and operate a Daily Wash. This cycle executes both tap
water and DI water rinses (if applicable).
 While the cycle is operating, carefully check all water supply and
drain connections to ensure that there are no leaks. Correct any
observed leaks before continuing.
5. Position the unit in its final location. For freestanding and mobile units, secure
the unit by depressing the caster break levers on the unit’s casters.
6. Adjust the leveling legs as required.
On undercounter units, leg height may be adjusted by using a 5/8-inch (16
mm) wrench. Any inclination must be ≤ 2 degrees. Use the locking nut to lock
your adjustments

7. Secure the washer in its final location.
 For undercounter units:
To prevent forward tilting when downward force is applied to the
open door, or when heavily loaded baskets are pulled outward, use
the supplied screws to fasten the washer to the cabinet. Secure the
washer to the cabinet using either option “A” or option “B” (one
screw on each side) as follows:
 For freestanding and mobile units:
If your application creates a potential for forward tilting, use the
supplied Tip Guards or similar brackets to secure the washer’s rear
casters to the wall or floor.

8. Install the optional Toe-Kick Plate, if desired. The Toe-Kick Plate attaches to
the washer’s lower front to optimize appearance, but is not required for
operation of your unit.
To install 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 on to the front of the bracket.
