Horizontal Right Installations - Mitsubishi Electric MVZ-A12 Manuel D'installation

9.2. Horizontal right installations

Refer to section 9.3. Step 1 to 4 & 12 for removing the entire coil
assembly from the air handler cabinet. This will require removing
the Filter, Blower, Electrical and Coil Panels along with the brackets
that secure the coil assembly. Be sure to also route the thermistor
wires out of the electrical portion of the air handler so the coil can be
removed.
Once the coil is removed, the two clear plastic tubes included in
the accessory bag will need to be attached to the top drain pan.
First, remove the lower rubber plugs in the top drain pan. Next,
install the clear plastic tubes which are included in the accessory
bag. Ensure the plastic tubes drain into the pan. Also, be sure the
clear plastic tubes do not have any restriction. Cutting of the plastic
tube is required, please refer to the table for length. Finally, secure
the clear plastic tubes to the top drain pan per Detail A. Then to
the metal brackets supporting the coil to the top drain pan with the
provided plastic ties as shown.

Reinstall the coil assembly along with bracket(s) that secure(s)
it. Failure to reinstall the brackets will result in capacity loss and
condensation formation inside the cabinet. The wiring harness for
the thermistor connector will also reroute into the electrical section
and plug into CN44. Refer to 9.3. Step 1 to 4 in reverse order to
reassemble the panels. Ensure the proper knockouts are removed
for drainage and electrical connections.
NOTE: For Horizontal installation an auxiliary drain pan must be
installed.
