Installing the Components
3.1
Fitting the sensor
•
With a cold engine release the retaining clamps and remove the exhaust
hose from the engine and outlet.
•
Drill a 10mm diameter hole through the hose (Fig. 2), in the top section as
close to either the 10
o’clock
or 2 o’clock
positions as possible and
approximately 75-100mm downstream of the end of the exhaust elbow as
detailed in Fig. 2.
•
Tidy up the edges of the hole as necessary.
•
Identify the correct components from the sensor kit as per Fig. 1.
•
Fit rubber grommet G into the centre of one of the large penny washers D.
(A smear of silicone sealant may assist)
•
Smear both sides of the washer/grommet with silicone sealant and screw the
combination onto the thread of the sensor until the grommet fits snugly
against the underside of the sensor base.
•
Clean the area of the hose around the drilled hole to remove any dirt and
grease
•
Apply silicone sealant to the hose immediately around the drilled hole, both
inside and out, using the silicone sealant supplied.
•
Insert the sensor probe through the hole in the exhaust hose.
CAUTION:
If the exhaust hose
retaining clamps are in
poor condition or are
damaged during the
removal, they MUST be
replaced otherwise
exhaust gases may escape
and water leaks occur.
Before removing the hose
ensure that the outlet and
inlet are well above the
waterline.
NOTE:
Please contact Halyard
