The framing instructions call for a 12 X 18 pump excess opening, but farther down in the instructions it states that a matched skirt can be used for pump excess. Does this in a nutshell infer that its one or the other?  Thank you.

Asked by: John
Thank you for your question, John. You are correct. Access must be provided to the pump or other equipment should service be needed at a later date. You can either build one into your surround, or install the unit with the optional skirt, which has a removable access panel built in. Please let us know if you have any other questions.

Does the 4160620 soaker model need support at the adjacent walls such as a two x four under the tile flange?

Asked by: Paul
Thank you for your question, Paul. The Montrose I comes standard as an island drop-in unit. If installed as such, the unit should be supported at the base--not by the rim of the tub--with a bed of casting plaster or plaster of paris. If installing in an alcove with the integral tiling flange option, use 1” x 3” leger strips along with the foundation materials, as illustrated in the framing diagrams on page 8 of the installation instructions. For additional information on the installation of your unit please refer to pages 8-10 of the product’s installation and owner’s manual. I’ve included the link below for your reference.
