Section 2 Installation
2.1 Introduction
Kohler transfer switches are shipped factory-wired,
factory-tested, and ready for installation. Have the
equipment installed only by trained and qualified
personnel, and verify that the installation complies with
applicable codes and standards. Protect the switch
against damage before and during installation.
2.2 Receipt of Unit
2.2.1 Inspection
At the time of delivery, inspect the packaging and the
transfer switch for signs of shipping damage. Unpack
the transfer switch as soon as possible and inspect the
exterior and interior for shipping damage. If damage
and/or rough handling is evident, immediately file a
damage claim with the transportation company.
2.2.2 Storage
Store the transfer switch in its protective packing until
final installation. Protect the transfer switch at all times
from moisture, construction grit, and metal chips. Avoid
storage in cold or damp areas where moisture could
condense on the unit. See Figure 2-1 for acceptable
storage temperatures.
2.2.3 Lifting
Unbalanced weight.
Improper lifting can cause severe
injury or death and equipment
damage.
Use adequate lifting capacity.
Never leave the transfer switch
standing upright unless it is securely
bolted in place or stabilized.
WARNING
See Figure 2-2 or the dimensional drawing for the
weight of the transfer switch. Use a spreader bar to lift
the transfer switch. Attach the bar only to the
enclosure’s mounting holes or lifting brackets; do not lift
the unit any other way. Close and latch the enclosure
door before moving the unit.
2.2.4 Unpacking
Allow the equipment to warm to room temperature for at
least 24 hours before unpacking to prevent
condensation on the electrical apparatus. Use care
when unpacking to avoid damaging transfer switch
components. Use a vacuum cleaner or a dry cloth to
remove dirt and packing material that may have
accumulated in the transfer switch or any of its
components.
Note: Do not use compressed air to clean the switch.
Cleaning with compressed air can cause debris
to lodge in the components and damage the
switch.
