July 2012
Thank-you for purchasing LECO analytical equipment. Installation by LECO service personnel is
included as part of your purchase. The following information is provided so that the installation site can be
properly prepared prior to the arrival of LECO personnel. Please follow the information for your new
instrument carefully in order to assure proper site preparation. If any questions arise during site
preparation, contact the LECO Service Department (Phone: 269-982-5497 Fax: 269-983-1477).
PRE-INSTALLATION GUIDE INSTRUCTIONS
1. Prepare your installation site according to the information listed (in regards to: floor space, power
requirements, gas supplies, gas tank regulators, and environment characteristics). Complete the
Site Preparation Checklist (page 6) and fax the completed form to the LECO Service
Department at (269) 983-1477.
2. When your instrument arrives, inspect all boxes and crates for outer damage. Carefully unpack all
boxes and crates to cross-check the contents with the packing list accompanying each box.
3. Call your LECO Sales Representative and inform them that you have received your instrument
and would like information sent for your specific application(s).
4. Call the LECO Service Department at 269-982-5497 to arrange an installation date. Keep in mind
that all dates agreed upon are tentative and subject to change. Also, if anything is missing from your
shipment or if anything was damaged during shipping, please inform the Service Department at this
time.
5. Once you have scheduled an installation date, please provide adequate security for the instrument
and the contents of the boxes shipped to ensure nothing is missing when the LECO Service
Technician(s) arrives.
6. After scheduling, make arrangements for the appropriate personnel to be present at the installation
and training sessions. In most cases, installation is completed within the first day and training takes
place for the remainder of the first day and most of the second day.
7. Following all of the above steps will aid the LECO Service Team in providing you with the highest
quality installation and training.
NOTE:
If the above steps are not followed, LECO will not be responsible for delays, cancellations, or
rescheduling of installations.

FLOOR SPACE
Before your instrument arrives, make sure you know where it will be installed. When factoring overall floor
space requirements, a minimum 6-inch (15 cm) access area should be factored in around each unit. Also
factor in appropriate space for PC, monitor, keyboard, and printer to be used with the unit.

POWER REQUIREMENTS - ELECTRICAL WIRING DIAGRAMS
A detachable line cord is supplied with each package. A female receptacle is provided with each 230
VAC package. Refer to the electrical wiring diagrams on this page.
TruSpec ...............................................................
230 VAC 10% at max load, 50/60 Hz, 12 amps.
NOTE: If line voltage is 210 VAC or less, LECO strongly recommends the use of a step-up
transformer. LECO offers three options for power purification:
1) a basic auto-transformer (LECO part number 625-401-350) that does not
require hard-wiring. This is a step-up transformer only with no power
conditioning.
2) the 621-325 Transformer/Power Conditioner which also does not require
hard-wiring. This option is for use with Truspecs that have either the Sulfur
or Oxygen add-on module (both units connected).
3) the 621-376 Power Purifier is for stand alone Truspecs. This unit offers no
support for add-on modules.
