PREREQUISITES REREQUISITES
Before you install the Pipette Washer Dryer, prepare your site for installation.
Carefully examine the location where you intend to install the Pipette Washer
Dryer. Be sure the area is level and of solid construction. In addition a water
source, a drain, electrical and compressed air sources must be located near the
installation site.
Refer to Appendix C:ScrubAirPipette Washer Dryer Specifications for complete
Pipette Washer Dryer electrical and environmental conditions, specifications and
requirements.
The ScrubAir Pipette Washer Dryer is equipped with a single water supply/drain
hose quick connector that can easily be attached to your sink faucet. If preferred,
the ScrubAir Pipette Washer Dryer can be installed using dedicated water supply
and drain piping.
CAUTION: If the unit is not operated as specified in this
manual it may impair the protection provided by the unit.
PRUDENCE: Si l'unité n'est pas utilisée comme spécifié dans
ce manuel il peut diminuer la protection fournie par l'unité.
Water Requirements
The water supply for non-heated models can be tap or purified water. An existing
hot water supply may be used as the water source. Though not required, Labconco
recommends the inlet water temperature be greater than 120°F (49°C). Hotter
water will produce better washing results but should not exceed 140°F (60°C).
The heated models have and additional water inlet valve to allow for connection
to a purified water source. A 3/8" (9.6 mm) O.D. x 6’ (1.8m) long polyethylene
tube is attached to the rear of the ScrubAir Pipette Washer Dryer (marked “P”) for
connection to a dedicated pure water source. This tube can be shortened as
required, a shut off valve is recommended.

The heated models do not require a heated water source for the tap or the pure
water but using heated water will allow the washer to reach the 140°F (60°C)
wash temperature faster.
Water pressure for both tap and pure water must be between 8-120 psi (55-827
kPa) at the washer and provide a minimum of 1.33 gallons (5.0 liters) per minute
flow rate.
By using the factory- installed quick connect hose coupling, the tap water/drain
hoses can easily be connected or disconnected to a sink faucet. If using the quick
connect hose coupling, a sink with a drain and threaded faucet is required. See the
illustration that follows. Since the quick connect hose assembly length is 6’
(1.8m) the installation should be within this distance to the faucet.

If a dedicated tap water supply is preferred a shut-off valve should be installed in
the water supply line plumbed for the washer.
Electrical Requirements
Minimum requirements for an outlet is a 15 Amp circuit breaker or fuse for
models rated at 115V (60 Hz) or an 8 Amp circuit breaker or fuse is required for
230V (50/60 Hz) models. The 115V models are equipped with a 15 Amp NEMA
5-15P plug. 230V models are available with a NEMA 6-15P plug for use in the
United States, a PS 1363 plug for use in the United Kingdom, a CEE 7/7 plug for
use in Europe, a CHI-10P plug for use in China or a SANS164-1 plug for use in
India. It may be necessary to remove the plug and install a different one to match
the available receptacle if one of these models does not meet your needs.
Drain Requirements
The Washer Dryer is designed to use air pressure to drain the washer. If using the
quick connect hose coupling, a sink with a drain and threaded faucet is required.
Since the quick connect hose assembly length is 6’ (1.8m) long the installation
should be within this distance to the faucet.

Chapter 2: Prerequisites

Dedicated Drain Installation
It is recommended that the drain hose and drain hose outlet be routed as low as
possible relative to the base of the washer, to allow gravity to assist in draining
the washer. Low spots where water can sump in the drain line should also be
avoided. If the drain hose must be higher, no section should be more than 11”
(27.9 cm) above the base of the washer.
Tubing or pipe, 1.25 (3.2 cm) ID or larger, should be provided for the building
drain. The use of an air gap (as shown above) where the drain hose is connected
to the building drain plumbing is required.
Do not reduce the size of the drain plumbing.

Compressed Air/Inert Gas Requirements
The 3/8" (9.6 mm) O.D. x 6’ (1.8m) long polyethylene tube on the rear of the
ScrubAir Pipette Washer Dryer should be attached to a regulated source of air, or
other suitable inert gas. This tube can be shortened as required. Pressure must be
at least 20 psi (138kPa) and a minimum flow rate of 5 cfm (142 l/m). The
pressure must not exceed 100 psi (689kPa). A suitable push-to-connect or

Connecting the Compressed Air Supply
If not connected, mark the 3/8” (9.5mm) outside diameter air supply hose 3/4" (19
mm) from the end and push the hose into the fitting in the back of the ScrubAir
Pipette Washer Dryer marked AIR. Attach the other end of the hose to user
supplied air or insert gas supply. Turn on the air supply.
Connecting the Water Supply
To prevent valve clogging, thoroughly flush the water lines for your water supply
source prior to connecting the washer to the water line. The tap water supply hose
is connected to the press to connect fitting at the back of the washer base marked
W. The 3/8 OD pure water supply hose is connected to the press to connect
fitting at the back of the washer base marked P.
If using the quick connect hose coupling for the tap water supply, an aerator
adapter and a standard adapter fitting are provided and need to be installed on the
faucet. Refer to illustration on page 4. If the adapter fittings provided do not allow
for a tight connection to the faucet, a variety of internally and externally threaded
fittings are available at local hardware stores. Use caution when installing the
fittings to prevent stripping the threads.
The hose faucet coupling attaches and seals to the aerator adapter by pushing the
parts together. The hose end faucet coupling must be snapped into place before
turning on the hot water. Turn the water on slowly until the faucet is fully open.
When the coupler is attached to the faucet, water can be obtained through the
bottom of the coupler by pressing the pressure release button.
The hose faucet coupling may be removed from the faucet when the washer is not
in use. Make sure both the hot and cold water faucets are turned off. Push the
pressure relief button on the hose faucet coupling to relieve the water pressure.
Pull down on the release ring on the hose coupling to disconnect it from the
faucet.
