Installation, Owner, and Diagnostic Manual IntelliPak® - Trane

Note: The compressors and fan assembly
are internally isolated. Therefore, external
isolation devices (spring mounting
isolators) are at the discretion of a vibration
specialist consulted by the building or
HVAC system designer. In general, the
Trane Company does not recommend
double-isolation.
Installation
Unit Vibration Isolator Option
Vibration isolation is not necessary for the
unit since the factory internally isolates
the fan and compressors, thus creating
double isolation. The Trane Company
strongly recommends that you consult a
vibration specialist when considering
double isolation. If job requirements
dictate unit isolators, use a housed-spring
isolator with a locating pin. Factoryprovided
unit isolators are type CP and
indicate the spring number on the outer
housing. See Figure I-PR-3. Set the
spring-type vibration isolators in position
before completing electrical, piping, or
duct connections. Units require four
isolators per unit. Reference the isolator
placement sheet that ships with the
isolators to indicate proper placement.
Unit Isolator Installation Procedure
Follow the procedure below to install
isolators:
1. Position the isolators under the unit
base referring to the isolator placement
sheet that ships with the unit isolators.
Lift one end of the unit at a time to
position the isolators. Fasten the
isolators to the floor using anchor bolts.
2. Level the unit by adjusting the isolator
heights. Unit weight may cause the
Pre-Startup
Requirements
upper housing of the spring isolators to
rest on the lower housing. Maintain
clearances between 1 /4 to 1 /2”. To
increase the clearance, lift the unit off
the isolator and turn the leveling bolt
counterclockwise. Verify that the unit is
level and the housing clearances are
correct. The maximum allowable
difference between isolator heights is
1 /4”. Shim as required under the
isolators.
Note: The unit is equipped with a positively
sloped drain pan to help indoor air
quality (IAQ) and does not require one
corner of the unit to be pitched.
