GENERAL. The Barnstead Electrically Heated Portable Still provides high quality distilled water at the rate of 1.8
liters/hour. The still is designed to use approximately 14.4 liters of cooling water and feedwater combined for each 1.8
liters of distilled water produced. Two electrically powered, inmmersion-type heaters are used to give complete heat
transfer and maximum heating efficiency.

20 1/2 in.
9 1/2 in.
19 3/8 in.
*A hose nipple is provided for a 1/2" hose connection if a permanent connection is not desired.
**The still is rated at 1300-watts and operates on 115 or 230-volts AC or DC. The still will draw 12-amperes of current at
115-volts and 6-amperes of current at 230-volts. The still is wired for 115-volts at the factory, but may be converted to
230-volts in the field by replacing the plug and reconnecting the heating elements as shown in the wiring diagram in this
UNPACKING. Unpack the still carefully to prevent damage. Ensure that all parts are removed from the container before
discarding the packing materials.
SITING. Move the still evaporator to the operating location and install the evaporator so that it is level and plumb.
PLUMBING CONNECTIONS. Connect the water and waste service lines to the still. Ensure that the waste service line at
the still is atmospherically vented and gravity flow. A shut-off valve and throttling valve should be installed in the water
supply line, just before the still, if the still is to be permanently oiped. If the still is not to be permanently piped, a hose
may be connected between the inlet hose nipple connection and a water faucet. The water faucet may be used as a
water throttling valve. The distillate delivery tubing should be connected to the point of distribution or storage.
NOTE: Ensure that the service piping is adequately supported. The still is not designed to support the service piping.
ELECTRICAL CONNECTIONS. The still may be connected electrically by connecting the cord to a 115-volt or 230-volt
AC or DC, grounded electrical service. See the nameplate on the still evaporator for the electrical requirements.
THE HEATERS ARE IMMERSION-TYPE HEATERS, AND WILL BURN OUT IF OPERATED IN AIR. READ
THE OPERATION SECTION BEFORE CONNECTING THE STILL TO THE ELECTRICAL SERVICE.
WARNING: A FIRE HAZARD MAY RESULT IF THE STILL IS USED WITH A FLAMMABLE LIQUID.
