Mechanical Installation Of A Stand-Mounted D-Frame Afdh - Trane CVHE Installation Manual

Mechanical installation of a stand-mounted D-Frame AFDH

Heavy Objects!
Only attach cables (chains or slings) to the designated lifting points. Each of the cables (chains
or slings) used to lift the unit must be capable of supporting the entire weight of the unit. Lifting
cables (chains or slings) may not be of the same length. Adjust as necessary for even unit lift.
Other lifting arrangements could cause equipment or property-only damage. Failure to properly
lift unit could result in death or serious injury.
Improper Unit Lift!
An AFDH drive cabinet assembly is top heavy. Test lift unit to an approximate height of no
greater than 24 inches to verify proper center of gravity lift point. To avoid dropping the unit,
reposition lifting point if unit is not level. Failure to properly lift unit could result in death or
serious injury or possible equipment or property only damage.
NOTICE:
Stand-mounted AFDH supported by equipment room floor!
A stand-mounted version of an AFDH drive is designed to be rigidly supported by the equipment
room floor. Therefore, a stand-mounted AFDH drive is not recommended for use with a chiller
that is equipped with spring-type vibration or seismic isolators. Trane recommends using a
remote floor-mounted AFDH drive in this application. Trane assumes no responsibility for
equipment damage caused by the installation of an AFDH drive version that is specified as being
incorrect for the application.
NOTICE:
Incorrect application! Adapting a floor stand kit to an E-Frame AFDH!
When properly installed, the part number 50689890010 Floor Stand Kit is designed to safely
support the weight of D-Frame model AFDH drives only. The largest model D-Frame drive
weighs 872 pounds. The smallest model E-Frame drive weighs 1193 pounds. Any attempt to
adapt the 50689890010 Floor Stand Kit to an E-Frame model AFDH drive will be considered an
unsupported field modification to the drive unit design. Trane assumes no responsibility for the
equipment damage caused by a stress or fatigue failure of the floor stand kit due to any use
outside of its intended application.
NOTICE:
Improper Unit Lowering!
Do not drop the stand-mounted drive cabinet assembly down onto the mounting surface when
setting it into position! Dropping the cabinet could result in damage to the stand legs and/or
the drive cabinet.
1. Ensure that the section of floor or concrete pad that has been prepared as the installation
2. Assemble the floor stand from the component parts provided

location for the stand-mounted AFDH drive unit is as level as is possible.
a. Set the assembled stand onto the floor or pad surface at the exact position where the drive
will be installed oriented in the correct direction.
b. Using the stand feet as a template, mark the hole locations for the locally supplied concrete
anchor bolts that will be used to secure the entire drive assembly to the floor, and drill the
required holes.
