5.1 Feed the pump power cord and the attached cord seal through the 2 ½" hole in the lid. The cord seal must be
bent and forced through the hole. Remove slack in the cord, making sure cord does not interfere with the float
movement. Do not press cord seal into the lid at this time.
5.2 Place model 105 drain pump into basin per Figure 5.1. Place Model 135 drain pump into basin per Figure 5.2.
Ensure the float switch is positioned for up and down movement without interference from the power cord or the
tank wall.
5.3 Slip open end of short discharge pipe into 1 ½" slip fitting in lid.
5.4 Adjust lid and pump so that "keyed" notches on lid and basin are aligned. Push bolts through holes and foam
seal. Bolt lid evenly to basin using bolts, nuts, and washers supplied. Do not over tighten.
5.5 Attach a check valve to discharge pipe with flow away from pump. To avoid unnecessary cycling, check valve
should be installed no more than 3" above lid.
5.6 Connect 1 ½" discharge pipe and 2" vent pipe into existing house plumbing. THE UNIT MUST BE VENTED. Do
not over tighten the discharge and vent pipe into the threaded connections on the lid.
5.7 Press cord seal into cord seal hole in lid. Use soap water for lubricant. Securely tape or clamp cord to
discharge pipe or vent pipe.
