Checking
the gap
between
the lever
unit arm
and the
pivot pin
• No action
required
• It is necessary to inspect the gap to determine whether adjustment is
necessary
only
when installing a new trap unit or an overhauled trap
unit (from this or another PowerTrap).
• The trap unit must be installed before the gap inspection can be
carried out. A feeler (go/no-go) gauge to be used in gap inspection is
supplied with each spare trap unit and with each spare snap-action
unit (see step 5a.). To check the gap, carefully slide the thick end of
the feeler gauge (marked FL) into the gap between the lever unit
arm and pivot pin.
Use this end
• If the gap is already adjusted properly, the gauge will stop when it
touches the support bracket (it will also be touching the float).

• No action

• When a trap unit that has been removed from the cover is reinstalled
without being overhauled,
do not loosen
the lock nuts.
• If the previous inspection reveals that the gap is out of the accepted
range, proceed with gap adjustment.
• Using two 17 mm (
21
⁄
32
in) wrenches (one an open-end wrench, and
one an open-end torque wrench), hold the lower nut steady with the
open-end wrench while loosening the lock nut with the open-end
torque wrench.

• To increase the gap, lift the float and rotate the trap valve
counterclockwise.
• To decrease the gap, rotate the trap valve clockwise.
• Finger tighten the lock nut and use the feeler (go/no-go) gauge to
recheck the gap.
• When adjustment is complete, hold the lower nut steady with the
open-end wrench and tighten the lock nut with the open-end torque
wrench to a torque of 40 N
⋅
m (29 lbf
⋅

• Recheck the gap, and, if necessary, repeat the adjustment
procedure.
