The purified water system must be provided with supply piping of sufficient size
to permit at least 0.9 gallons (3.4 liters) per minute of flow. Tubing with an
internal diameter of at least .375
" (9.53 mm) is recommended. The purified water
inlet valve on the washer is equipped with a plastic hose barb connection to
accommodate .375
" (9.53 mm) 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 3/4
" - 11-1/2 NH
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
Undercounter and Freestanding models, are 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).
High voltage models are designed to operate at 230 VAC, single phase. It will
operate safely at nominal 208 VAC, however the heater output will be reduced
proportionally. As the operating voltage drops below 230V a boost transformer
can be used if higher voltage is preferred.
If your Glassware Washer is converted to 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.
