Condensation Water Drain Hose, Removing And Installing: Installing

Install in reverse order of removal. Note the following:

-- The condensation water drain hose can only be slid onto the heater and A/C unit in one position until stop.

-- Additionally secure the condensation water drain -3- to the heater and A/C unit connection -1- with a cable tie or a hose clamp.

NOTE:

The condensation water drain -3- must not sit loosely on the connection for the heater and A/C unit -1- (condensation water can escape with a loose fit).

-- Install the condensation water drain hose -6- until it engages audibly in the floor panel opening in the body (this illustration shows version "A").

NOTE:

The sealing lip must not sit loosely on the floor panel body opening.

The retaining tabs -1- (on the version -A-) or -4- (on the version -B-) must engage completely.

If the pre-tensioning is not adequate, seal the area between the body and the condensation water drain, for example with silicone adhesive. Refer to the Parts Information.

NOTE:

Install the condensation water drain hose so that it is not twisted or crushed.

Make sure the carpet does not push up against the condensation water drain hose when installing.

If the condensation water drain hose sits too loose on the heater and A/C unit connection, secure it, for example, with a hose clamp or a cable tie so that it cannot slide off and fluid cannot escape. Cable tie and hose clamp. Refer to the Parts Information.
