Troubleshooting Guide - Air King AK200LS Important Instructions & Operating Manual

2. Run wiring from an approved wall switch (not included) carrying the appropriate
rating. One neutral (white), one ground (green or bare copper), and one hot (black lead
connected to the switch). Secure the electrical wires to the housing with an approved
electrical connector. Make sure you leave enough wiring in the box to make the
connection to the fan's receptacle.
3. From where you have chosen to access the fan's junction box, connect the white wire
from the house to the white wire from the fan's receptacle. Connect the black wire
from the wall switch to the black wire from the fan's receptacle. Connect the ground
wire from the house to the green wire from the fan housing (Figure 8). Use approved
methods for all connections.

NOTE: The fan's receptacle wires might need to be pulled outside the compartment for connection.
Only pull the three loose wires outside of compartment. Additional wires will be present.
NOTE: Unit must be grounded according to all local and national codes.
3. Carefully tuck wire back inside wire compartment and replace wire compartment cover
securing with the screw that was removed earlier.
SECTION 6
Completing the Installation
1. Use a sealant appropriate for contact with the building materials present and for the
temperature requirements of the installation to prevent air leakage from unconditioned
spaces is recommended. If gaps between unit housing and ceiling are great, additional
material (backing rod, ceiling material) may be required.
NOTE: This fan is rated for direct insulation contact (Type IC) and it is recommended that this fan
be completely covered by insulation in order to reduce heat loss or gain to unconditioned space.
2. If the fan's blower assembly was removed during the wiring process, reinstall the
blower by reversing the directions in Section 5 (Wiring), Step 1b.
3. Plug the fan's quick connect motor cord into the receptacle. This cord will only fit one
way into the receptacle (Figure 9).

4. Install the ceiling mounting flange to cover any gaps which exist between the housing
and the finished ceiling. Remove the two screws that connect the ceiling mounting
flange to the housing. Put sealant (not provided) on inside edge of the ceiling mounting
flange to ensure that the flange is sealed to the
ceiling mounting flange with the screw holes on the inside of the housing and press
flange in place so it is tight against the ceiling. Reinstall ceiling flange mounting screws
inside the housing (Figure 10).

NOTE: If the housing is mounted too far or not far enough into the ceiling for the flange to
make a solid connection, loosen the mounting channel and adjust the housing up or down on
the rails. Once in place, fully tighten the mounting channel nuts.
5. Install the grill by squeezing the two ends of the springs together and installing them up
into the slots on the fan's housing. Push the grill up into position (Figure 11).
