Requirements for Installation of Automatic D1160 System
Electrical Requirements.
Two single phase 120 or 220/240 VAC., 50 Hz/60 Hz, dedicated electrical outlets
within 3 feet of the installation site. The amperage required depends on the particular
system ordered. Please specify Voltage and Hz when ordering. The electrical power
must be clean. Fluctuations in the power or noise on the power line may cause
equipment malfunctions. Any abnormalities in power should be reported in detail at
the time of ordering.
Nitrogen
As an option, gaseous nitrogen can be used as a bleed gas for vacuum control instead
of air. If nitrogen is to be used as the bleed gas, a gaseous nitrogen source is
required. The cylinder should be equipped with a two stage regulator with a hose
barb adapter to accommodate a 3/8" ID hose. The regulator should measure in 1 lb.
increments, up to 30 lbs.
Manual Cold Trap
The manual cold trap requires dry ice and acetone.
Venting.
A vent to the outside should be provided to vent the vacuum pump exhaust.
Environment
The area in which the instrument is operated should be free from all ignition sources
such as sparks and flames and be well ventilated. Flammable solvents should not be
stored within 5 feet of the system unless those solvents are contained in a flammable
storage cabinet.
The area should also be temperature controlled between 20C (68 F) and 27C(81F)
with a relative humidity less than 80%.

Cleaning
A source of reagent toluene or cyclohexane should be available for cleaning the unit
after each run.
Freight
This equipment is very fragile. There are many delicate glass pieces and electronics
packed with the unit. Koehler takes great care and expense in packing this
equipment. The customer should take all possible precautions to ensure that the
equipment is handled carefully and given a smooth ride during shipment. Keep in
mind that this is a very delicate and valuable piece of equipment. Please see to it that
it is treated as such.
Please remember that the technician will be traveling a long distance to install and
train laboratory personnel. Having the site properly prepared will lead to quick
installation and allow more valuable time to test the unit and train lab operators!
Please pay careful attention to each of the requirements listed above. If you have any
questions please contact Koehler Instrument for advice. Thank you for your attention
to this matter.
Reporting Damaged Equipment
Damage due to shipment must be reported immediately to both the carrier and
Koehler Instrument Company, Inc. Neither the carrier nor Koehler will be
responsible for damages reported after 14 days from shipment. It is the customer's
responsibility to report any damage to the carrier. Please call 1 631 589 3800 to
report damage to Koehler Instrument.

Cautions
Read all instructions carefully before unpacking your system.
Installation and training is provided by a trained technician. All operators should be
trained in the safe and proper operation of the system. Training is provided during
installation, but you may feel that more training is necessary at a later date. To
arrange for further training, please contact us.
Your company should develop standard operating procedures for safe and proper
operation of the D1160 System.
For your protection, never plug in and turn on the power until the installation has
been completed in its entirety.
Laboratories using flammable solvents should be protected with an automatic fire
extinguishing system.
Goggles, gloves, and other protective safety equipment should be provided and used
when handling petroleum products and chemicals.

Equipment Description
Description Fully Automatic D1160 Components
Figure 1
Vapor Temperature Probe: This temperature probe measures the actual vapor
temperature.
Pot Temperature Probe: This temperature probe measures the temperature of the
liquid in the pot flask.
Controller: Controlls the distillation system and includes display and keyboard.
IBP Sensor: Automatically detects first drop (Initial Boiling Point).
Receiver and Level Follower: This is where the distillate is collected and the volume
is measured automatically.
Heating Mantle: Provides heat to the pot flask.
Vacuum Sensor: Senses the vacuum level.
Vacuum Bleed Valve: This automatically operated valve allows air or nitrogen into
the distillation system to regulate the vacuum level.
Cold Trap: Filled with dry ice (solid CO2). The cold trap protects the vacuum pump
and pressure sensor from uncondensed gases.
Distillation Column: Column for distilling the sample.
Pot Flask: Flask for distilling the sample.

System Preparation
Preparing the System
Operational Checks
1. Check the condenser bath level. The level should be maintained above the coil
inside the bath.
2. Verify that a clean receiver is in place and empty. The metal drip trough should
be pointing directly to the front of the unit. The metal drip trough should also be
touching the side of the receiver.
3. Verify that the receiver joint is greased.
4. Put dry ice in the cold trap.
5. Check the vacuum pump oil level. It should be near the high mark.
Electrical System Check
1. The Control Unit power should be in the ON position.
2. The Condenser Bath power switch should be in the ON position.
3. The Vacuum Pump power switch should be in the ON position.

Software Operation
General
The D1160 control software is designed to make vacuum distillation as easy as possible.
The Main Screen is displayed when the program is started. It gives various options for
common tasks
Manual Controls: This area is used for manually operating all aspects of the equipment.
The vacuum pump, bath, level follower and so forth can be manually operated. At the
same time vacuum level and various temperatures can be monitored. This is useful for
checking the equipment function and performing maintenance.
Manage Run Data: This area is used to create and edit distillation programs.
View and Print Results: This area allows data from distillations to be viewed or
printed.
