inlet valve on the washer is equipped with a plastic hose barb connection to

band hose clamp to secure the hose to the hose barb connection. The hose barb

hose coupling. Rigid plastic, tin-lined, or stainless steel tubing and fitting can be
connected to the washer fitting.
An optional Connection Kit (Labconco P/N 4592200) is available for connecting
.375" (9.53mm) OD plastic tubing to the purified water inlet valve. The purified
water system connections must be airtight to prevent the washer pump from
pulling air instead of water.
If the purified water is stored in a carboy, at least 3.4 gallons (13 liters) must be
available for each rinse. If all the purified water is not available at the start of a
wash cycle, but instead is produced concurrently with the wash cycle, the
production rate must permit at least 0.9 gallon (3.4 liters) per minute to be
delivered to the washer.
Electrical Requirements
The Glassware Washer should be hard-wired directly into a junction box using
conduit. A 20 Amp circuit breaker or fuse is required.
The Glassware Washer is designed to operate at 230 VAC, single phase. It will
operate safely at nominal 208 VAC, however the heater output will be
significantly degraded as the operating voltage drops below 230V. It is highly
recommended that if the voltage is low that a boost transformer is used.
Drain Requirements
The drain hose, .75" (1.9 cm) ID is installed during manufacture. 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, .75
"
(1.90 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 drain plumbing.
