Section 2 Introduction
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.
®VYCOR is a registered trademark of Corning, Incorporated.
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.
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. s

Electrical
Requirements (cont.)
Warning Do not connect unit to electrical service until so instructed. s
Warning To avoid electrical shock, use a properly grounded electrical
outlet of correct voltage and current handling capacity. s
The electrical controls have been designed to operate on voltages between
208 and 240 volts A.C.
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.

Introduction
Water Supply
Requirements
We recommend one of the following options for supplying water to
operate your MEGA-PURE 11A water still.
Option #1
A single, untreated cold water supply. The supply must be capable of
providing a minimum of 26 gallons per hour at a pressure of 20-100 psi
and be located within 4 feet of the water still. You must provide a shut-
off valve and reducer as shown in Figure 2-3.
With Option #1, approximately 26 gallons of untreated water will be
used per hour in the cooling section of the still, 3 - 4 gallons of this
water will be used as boiler feed. Water connections are discussed in
“Pretreated Boiler Feed” section.
Option #2
An untreated cold water supply plus a source of reverse osmosis, dem-
ineralized or previously distilled water. The untreated supply must be
capable of providing a minimum of 26 gallons per hour at a pressure of
20-100 psi and be located within 4 feet of the water still. The treated
supply must be capable of providing 3 - 4 gallons per hour and be locat-
ed within 4 feet of the water still. You must provide a shutoff valve and
reducer at each water supply (see Figure 2-3). In addition, the optional
double solenoid valve kit (Catalog No. 440236) is required.
With Option #2, approximately 26 gallons of untreated water will be
used each hour for cooling. The second (treated) water supply of 3 - 4
gallons per hour will be used as boiler feed. Water connections are dis-
cussed in “Pretreated Boiler Feed” section.
Caution Do not use NaCl regenerated water softeners to supply boiler feed
as alkali attack will shorten heater life. s
An open or vented drain located lower than the still is necessary to allow
for gravity flow. The factory supplies a 5 foot length of ½" I.D. vinyl
tubing for the drain.
Additional tubing may be purchased from your laboratory dealer.
