INSTALLATION—CONTINUED
5. Position louver frame in face plate so that holes align and secure frame through face plate to face plate assembly
using screws removed in step 4.
6. Install face plate assembly and secure to front of unit using screws removed in step 3. Replace door on right
side of unit.
NOTE: Before installing the louvers, note the louver curve and determine how the louvers should
be positioned to provide the optimal throw pattern. Depending on where the heater is installed
and on the desired airflow direction, the louvers may be installed with their curves all in the same
direction (either way) or the right half one way and the left the other.
7. Install vertical louvers in louver frame:
a. On notched end of louver, slide compression spring over tab.
NOTE: Depending on the desired throw pattern, the end of the louver with the spring can go either
into the frame top or bottom.
b. With wider louver blade facing in toward heat exchanger, push tab with compression spring into hole in top
or bottom louver frame (see Figure 2)—spring compresses. Insert tab on other end of louver into opposite
louver frame. For left airflow, compress spring into top louver frame. For right airflow, compress spring into
bottom louver frame.
