STEP 4
4.1) Feed the pump power cord and the attached cord seal through the 63 mm (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.
4.2) Place Model 135 drain pump into basin per Figure 4. Ensure the float switch is positioned for up and down movement without interference from the
power cord or the tank wall.
4.3) Slip open end of short discharge pipe into DN40 slip fitting in lid.
4.4) 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.
4.5) Attach a check valve to discharge pipe with flow away from pump. To avoid unnecessary cycling, check valve should be installed no more than 76 mm
(3") above lid.
4.6) Connect DN40 discharge pipe and DN50 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.
4.7) 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.
