Clamp
mounting for
pipe and
harness
Setup of pipe
cover
Wire harness
(electrical
wiring)
•
The pipe, harness clamp
or pipe cover is fastened
on the body with screws.
•
To protect the pipe and
harness from ice, snow
and flying stone.
•
To install pipe cover in
order to improve
appearance.
•
Wiring process
connecting relay box,
controller, refrigeration
unit and magnet clutch.
1. When the screw hole for the clamp is
drilled to the body, be sure to coat sealer.
t is recommended that seal will be
swelled out when the screw is tightened.
And don't clamp it together with the
high pressure pipe.
1. Install pipe cover when the pipe is stuck
out from the lowest tip of the chassis
and body or when the pipe is passed thru
the place where the stones scattering
from the wheels of the vehicle can easily
hit it.
2. Use sealer when screws are driven.
1. Before wiring works, disconnect the
battery terminal
2. Take care of polarity of battery wiring.
3. Select a place of 80°C or less
atmospheric temperature for wire
routing.
4. Clamp cable at 400 mm or less intervals
to avoid unnecessary sags.
5. Don't clamp together with the high
pressure gas pipe.
6. Use the clamp according to the thickness
of the harness. And when pulled lightly,
it should not be slid or pulled out. Also
be sure that the tip of the clamp does not
bites the wire harness or crush it. Clamp
the harness to the convenient direction.
1. Unless blocked by sealer,
water infiltrates into the
insulated material of the
body thru the clearance
to cause no-cooling.
2. The seal plays the role of
preventing the screw
from loosening.
1. Refrigerant leakage from
the cracked pipe and
many abnormalities
generated from the
refrigerant leakage. In the
worst case, the
compressor will be
broken.
1. If it is energized during
working, it will lead to
short circuit troubles, etc.
2. If the polarities (+) and (-)
are reversely connected,
the electrical parts will be
damaged (burnt).
3. Cable sheath may be
subjected to damage or
fire.
4. Interference with other
equipments
5. Temperature of high
pressure gas pipe
becomes high, causing
damage to the cover and
fire.
6. Broken wire and
effective contact
1. No remedy for the body
which has sucked water.
1. Verify that the battery
terminal is disconnected.
2. Replace the damaged
part.
3. Avoid placing it near the
engine exhaust pipe and
high pressure.
4.
5. Clamp the wire harness
alone.
6.
Holding of body, etc. by
screw
