Introduction
Section 2
The Thermo Scientific MEGA-PURE 11A water still is a compact, all glass
and PTFE unit designed to provide 11 liters per hour of ultra high purity
distilled water. The product water, as produced, is non-pyrogenic per
U.S.P. XIX and will have a resistivity of 1.0M ohm-cm or higher at the
product outlet using most tap water as feed. This water still can be used as
a discrete unit, with customer supplied pretreated water or in conjunction
with a Thermo Scientific Demineralizer. It can also be connected to the
Thermo Scientific Automatic Collection System for complete automatic
operation.
The MEGA-PURE 11A water still is rated at 240V, 50/60 Hz, 10,000
watts, single phase (Model A440118). It is also available in 208V (Model
A440117). Changing the unit for use on either 240V or 208V operation
requires only replacing the Vycor® immersion heaters with heaters having
the required voltage rating.
The cabinet and glassware are protected against damage from overheating
by two thermal switches.
Choice of a location for your MEGA-PURE 11A water still is primarily a
matter of convenience. This unit may be located on a bench or wall
mounted.

Electrical
To operate the MEGA-PURE 11A water still, the customer must provide a
power source of single phase, 50/60 Hz. 60 amp, 208 - 240VAC.
Requirements
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 Hubbel #9460. Figure 2-1 (on
following page) shows proper wiring for this receptacle. As an alternate
method, your electrician may remove the supplied plug and wire the cord
to a 60A-250V breaker box as shown in Figure 2-2.
Note If demineralizer is to be used, a 120V source of power will also be
required.
