Section 3: Installation
3.1. PRIOR TO INSTALLATION
1. Review the pre-Installation checklist.
2. Speak with the customer, outlining all the installation details.
3. Unpack and check all component contents.
4. Find best location for each component, referring to the site instructions.
3.1.1. Pre-Installation Checklist
The following points should be checked and discussed with the Area Sales
Manager and/or customer, if necessary, before the technician goes to the site
and installs the equipment.
Check the customer's application to make certain it is within the capabilities and
design parameters of the equipment.
If the installation process might disrupt normal business operations, tell the
customer and ask that they make ample arrangements.
Be sure that the equipment operator(s) are available for
training.
The service technician reviews the recommended setup with
the Area Sales Manager or Area Service Manager, and
together they identify all necessary variations to satisfy the
customer's particular application.

Section 3: Installation
3.1.2. Unpacking
Follow these guidelines when unpacking all equipment:
•
Check in all components and accessories according to the customer's order.
•
Remove all components from their packing material, checking against the invoice
that they are accounted for and not damaged.
─ Advise the shipper immediately, if damage has occurred.
─ Order any parts necessary to replace those which have been
damaged.
─ Keep the shipping container and packing material for future use.
Check the packing list.
•
Collect all necessary installation manuals for the equipment
and accessories.
•
Open the equipment and perform an inspection, making certain
that all hardware, electrical connections and printed circuit
assemblies are secure.
•
Do not reinstall the cover if the final installation is to be performed after the preinstallation checkout.
3.1.3. Finding the Best Location
Position the equipment with these points in mind:
•
Intense direct sunlight can harm the display.
•
Do not locate near magnetic material or equipment/Instruments which use
magnets in their design.
•
Avoid areas which have extreme variations in room temperatures. Temperatures
outside the Instrument’s specifications will affect the weighing accuracy of this
product.
•
Do not open the Instrument if there is any evidence of damage to it or any other
scale component or supporting structure.
•
When selecting the right location for the Instrument and the scale, keep the
components completely away from all high water, such as low-lying areas that
may flood, and away from any drain pipes.
