solid construction. In addition, a hot water source, a drain,
a purified water source (if applicable), and an electrical
source must be located near the installation site.

Carefully read this chapter to learn:

• the hot water source requirements for your

installation site.

• the purified water source requirements for your

installation site.

• the electrical supply requirements for your

installation site.

• the drainage requirements for your installation

site.

Chapter 2: Prerequisites

Chapter 2: Prerequisites

Refer to Appendix C: Glassware Washer Specifications for
complete Glassware Washer electrical and environmental
conditions, specifications and requirements.

Hot Water Requirements

An existing hot water supply may be used as the hot water
source for your Glassware Washer. However, the washer
requires the inlet water temperature to be greater than
120°F (49°C) to fully activate powdered detergents and
raise the glassware temperatures to achieve fast and
complete drying. For ultimate washer performance, a hot
water inlet temperature setting of 150°F (66°C) is
recommended.

Water pressure must be between 20 – 120 psi (138 - 827
kPa) at the washer and provide a minimum of 1.25 gallons
(4.7 liters) per minute flow rate.

Pressurization is not
required for the purified
water source.

A shut-off valve should be installed in the water supply
line plumbed to the washer. The hot water inlet valve on
the Glassware Washer is equipped with a female 3/8 NPT
fitting.

Purified Water Requirements

If you intend to use purified water for the final rinse cycle,
a purified water supply is required. The washer can be
connected to an in-house, pressurized, purified water tap; a
water purification system; or a purified water container.

The purified water system must be provided with supply
piping of sufficient size to permit at least 1.25 gallons (4.7
liters) per minute of flow (½" internal diameter (ID)
minimum pipe is recommended). The purified water inlet
valve on your washer is equipped with a plastic hose barb
connection to accommodate ¾" (2 cm) ID flexible plastic
or rubber hose. Use a spring or band hose clamp to secure
the hose to the hose barb connection. The hose barb
connection may be removed from the valve to expose a
male ¾" - 11-1/2 NH hose coupling. A rigid plastic, tin-

All connections on the purified water
system must be airtight so that the

!!!!

If the purified water is stored in a carboy, at least 5 gallons
(18.9 liters) must be available for each wash cycle. If all 5
gallons are not available at the start of a wash cycle, but
instead are produced concurrently with the wash cycle, the
production rate must permit at least 1.25 gallons (4.7
liters) per minute to be delivered to the washer. In
addition, all 5 gallons (18.9 liters) must be made available
over a 5-minute period.

washer pump is not allowed to pull air
instead of water.

Chapter 2: Prerequisites

Electrical Requirements

If your Glassware Washer is an Undercounter or
Freestanding model, it should be hard-wired directly into a
junction box using conduit. A 20 Amp circuit breaker or
fuse is required for models rated at 115V (60 Hz) or 230V
(50/60 Hz).

If your Glassware Washer is a Mobile model, a dedicated
electrical outlet is required. A 20 Amp circuit breaker or
fuse is required for models rated at 115V (60 Hz) or 230V
(50/60 Hz). 115V models are equipped with a 20 Amp
NEMA 5-20P plug. 230V models are equipped with a 15
Amp NEMA 6-15P plug. It may be necessary to remove
the plug and install a different plug to match the available
receptacle.

is installed at the factory prior to shipment. The hose
provides a flexible coupling to the building drain piping
and can be secured with a spring or band hose clamp. (A
band hose clamp is provided with the washer.)

Tubing or pipe, ½" (1.3 cm) ID or larger, should be
provided for the building drain. The use of an air gap is
strongly recommended to prevent siphoning of wastewater
into the washer.

DO NOT REDUCE THE SIZE OF THE

NOTE: If the purified water source is a carboy, complete
steps 5 and 6.

5. Connect the purified water source through either the

top or the bottom of the carboy, as illustrated in
Figures 3-10 and 3-11. If the purified water supply
feeds directly from the carboy top, make certain the
hose is submerged under the water line. Attach a
weight to the end of the tubing, as shown in Figure 3­11, to keep it from floating on top of the water and
possibly allowing air into the system.

6. Make certain the top of the carboy is vented to permit

proper flow from the carboy to the washer.

Installing Faucet Adapters

If you purchased a Mobile Glassware Washer, you need to
install a faucet adapter to provide a quick disconnect high­pressure coupling between the faucet and the hose-end
fill/drain connector on your washer. Examples of two
faucet adapter configurations are shown in Figure 3-12.

MAKE CERTAIN THAT ALL OF THE
CONNECTIONS ON THE PURIFIED
WATER SYSTEM ARE AIR TIGHT.
THE PUMP MUST NOT PULL AIR
INSTEAD OF WATER. MAKE
CERTAIN THE SUPPLY HOSE IS NOT
CRIMPED.

provided with your Mobile washer. If the adapter fitting
provided does not allow for a tight connection to your
faucet, a variety of internally and externally threaded
fittings are available at your local hardware store. Use
caution when installing the fittings to prevent stripping the
threads.

Attaching the Hose-End
Coupling

After you have installed the faucet adapter, the hose-end
coupling of your washer (shown in Figure 3-12) attaches
and seals to the aerator adapter by pushing the parts
together. The hose-end coupling must be snapped into
place BEFORE turning on the hot water faucet. Turn the
hot water on SLOWLY until the faucet is completely
open.

Connecting the Drain Hose

Before continuing with this section, be certain that your
drain meets the requirements detailed in Drain
Requirements in Chapter 2: Prerequisites. The washer
drain hose is connected to a fitting on the rear side of the
pump/motor assembly.

BE CERTAIN YOU CONFORM TO ALL
LOCAL PLUMBING CODES WHEN
YOU ROUTE AND CONNECT THE
DRAIN.

The drain hose is installed at the factory. The hose
provides a flexible coupling to the drain piping and can be
secured with a spring or band hose clamp. (A band hose
clamp is provided with your washer.)

The use of an air
gap is strongly
recommended for
all installations to
prevent the siphon­ing of waste water
into the washer.

Chapter 2: Prerequisites

Tubing or pipe ½" (1.3 cm) ID should be used for the
drain.

The drain piping can be routed to either a sink or a floor
drain. If you route the drain piping to a sink drain without
using an air gap, the highest point of the drain pipe must
be above the sink drain, as shown in Figure 3-13.

DO NOT ROUTE THE DRAIN TO AN
ELEVATION LESS THAN 15" (38 cm)
OR MORE THAN 30" (76 cm) ABOVE
THE PUMP DISCHARGE. DO NOT
REDUCE THE SIZE OF THE DRAIN
PLUMBING.

If an air gap is

not used, the

drain line must be

elevated above

the water level of

the sink.

into a junction box. Refer to Figure 3-16 and follow the
steps below to connect your washer to the appropriate
power source.

BE CERTAIN THAT YOU CHECK AND
CONFORM TO ALL LOCAL
ELECTRICAL CODES. DO NOT
DISTURB ANY INTERNAL WIRING IN
THE WASHER.
