The Barnstead MEGA-PURE
rated at 240V, 50/60 Hz, 5000 watts, single phase.
It is also available in 208V. Changing the unit for
use on either 240V or 208V operation requires only
replacing the Vycor
heaters having the required voltage rating.
The cabinet and glassware are protected against
damage from overheating by thermal switches.
Choice of a location for your MEGA-PURE
Water Still is primarily a matter of convenience. This
unit may be located on a bench or wall mounted.
Electrical Requirements
To operate the Barnstead MEGA-PURE
Still, the customer must provide a power source of
single phase, 50/60 Hz. 30 amp, 208 — 240VAC.
Your water still is supplied with a power cord and
plug. A certified electrician should install a
receptacle box within 5' of the still. The correct
receptacle to match the supplied plug is a NEMA
L6-30R. Figure 1 shows proper wiring for this
receptacle. As an alternate method, your electrician
may remove the supplied plug and wire the cord to
a 30A-250V breaker box as shown in Figure 2.
The Vycor® immersion heaters will be labeled
either 208V or 240V, according to your order. The
240 volt heaters may be used at 208V, 220V, 230V,
or 240V but at the lower voltages, there will be
some reduction in the volume of distilled water
produced. Exchange improperly ordered heaters
with your dealer. You cannot exchange heaters that
have been used.
