‘Waste Master Pre-Install Quick Check’ per Doc WM82
should be performed first to determine basic conditions
are met for install readiness.
This document, WM81, provides detailed information to
complete the installation. Before proceeding, verify your
RV’s set up with Diagrams 1 and 2 (Pgs. 5 and 6) in hand
and establish install parameters. These steps together
with compliance to Pg.7 check list will ensure full
confidence and successful system installation

Installation Steps
1. Complete Check list and modifications as required per Page 7 first to confirm install readiness
2. Determine mounting X and Y as Pre Diagram 1. Mark the hole centers in I-Beam and in
Enclosure ‘Wings’
3. Establish Drop Height as per Diagram 2. Doc WM89 provides Drop Height Table and HW
Configuration. Bracket kit provides a Drop Height range from 1” to 4.5”. For Drop Height >
4.5”, longer bolts may be required. Buy or order from Drain Master.
4. If applicable, install Vent Assembly Kit with threaded Female Cam Lock fitting Per Doc. WM91
5. Mount Bracket with 6 x Self tapping ¼” screws (included); pre drill a 3/16” pilot hole to guide
and ease self tapping screws. Use permanent strength thread locker Ex: Loctite Red 271.
Torque till Bracket is firm – do not over torque or threads may strip. Typical torque 10 Ft-Lbs
6. 4” Dia. hose exit hole must be precut in the enclosure; hole location as per Diagrams. 1 and 2.
7. Enclosure wings must have predrilled holes 7/16” dia. at the bolt mounting locations
8. Mount the enclosure to the bracket with 3/8 x 16 TPI HW based on Drop Height configuration.
Not all HW items may get used, this is OK – it depends on configuration.
9. Torque guidelines: 20 Ft-lbs HW to Mounting Bracket. Torque 10 Ft-Lbs HW to ABS enclosure
‘wings’ – it’s a softer material; Use permanent strength thread locker Ex. Loctite Red 271
10. Adjust the HW to attain desired Drop height - plumbing center line & hole align within 1/8”
11. Install Hose and test out system: Extend and retract as per Doc WM90 ‘WM User Manual’
