Evaporator Mounting – Drain Line Installation 
4.0” (100) 
Install the evaporator drain lines. 
A MINIMUM drop of 4.0” (100mm) is 
recommended between the drain pan outlet 
and where the drain lines exit the vehicle. 
Note the difference in drain line recommendations 
for perishable versus frozen applications 
For perishable applications, connect the water drain hoses 
together and route outside the vehicle. Note the diagram 
showing recommended ways of routing the lines. 
For frozen applications, do NOT tee drain lines together. It is 
important for each line to directly exit the vehicle in as short a 
distance as possible to prevent condensate from freezing. 
Make certain there are no low spots that can 
trap water in any of the drain line routings. 
Secure drain lines in place using ty-wraps or clamps.
