Installation Guidance:
Locate both mounting brackets and attach to evaporator unit as show below. Use two 1/4" x #20 x 5/8 hex bolts to attach brackets to unit combined with two 1/4" SAE
washers (hand tighten only at this time, see figure 1). These brackets are designed to allow you to adjust the installation angle and fine tune the final location to your particular
dash. With the brackets installed you can mark the locations to drill. Drill two 9/32" holes and test mount the evaporator. Once the evaporator is in place you can also spot a good
place to drill the two holes thru the firewall for the main hoses (check for obstructions first). Drill two 1 3/8" holes thru the firewall.
Once the two firewall holes are drilled and the included grommets interested into the holes, you can mount the evaporator back into place (it is a good idea to wait until you have
made all connections to the evaporator unit before tightening the bolts and nuts).
Locate the two 9" drain tubes. Using a sharp knife cut X's in the carpet in a non-conspicuous spot for the drain tubes (see figure 2). Drill two 11/16" diameter holes and attach drain
tube as shown below and push thru floorplan. These tubes will drain off the natural condensation.
You should now route the liquid and suction hose from the engine compartment thru the holes and connect to the evaporator unit. These hoses should be routed so that they are
not kinked or will interfere with any moving components under the dash.
Use the two-wrench method, to avoid stripping the threads (see figure 3). Once all the connections are made and snug, you can tighten the bracket nuts and bolts.
