Filter Installation; Supply Plug Fan Airflow Adjustment - Trane IC-IH 039 Installation Operation & Maintenance

Installation

Filter installation

Access to the filter cells is done via the filter access door.
Filter support can be slided laterally.
Each unit is shipped with this available filter
combination:
G4
G4+F7
G4+F9
F5+F7
F7+F9 combination is not allowed
The number and the size of the filter cells are determined
by the frame of the unit. Each unit has 2 rails of filter.
per rail
Frame 1: 6 filters of 500x625
Frame 2: 8 filters of 500x625
Frame 3: 12 filters of 500x500
There is 3 different types of filters which are place on
rails of 50 mm or 100 mm upstream of the indoor coil.

Supply plug fan airflow adjustment

1) Order write up (OWU) indicate design airflow, supply
and design air pressure drop.
2) Verify on site supply fan airflow. It should match
OWU design airflow.
3) If on site airflow is different from OWU design
airflow the actual supply and design air pressure
drop should be different from design values, Trane
service technician should be mandated to perform air
flow adjustment and optimization.
