FUNCTION
Similarly to the thermal expansion valve, the orifice
tube generates a pressure drop in the A/C circuit just
before the evaporator. That’s how cold temperature is
created in the A/C system.
>
REPLACEMENT
Due to dirt in the loop, the orifice tube can become
clogged therefore needing to be replaced.
>
RECOMMENDATIONS
In case of major clogging, flushing the loop must be
performed before fitting the new orifice tube.
>
FUNCTION
Caps protect the ports and
valves from damages and
dirt. They also help preventing
small refrigerant leaks on the
couplers.
>
REPLACEMENT
Caps must be replaced when damaged, leaking or every 3 years on average.
>
RECOMMENDATIONS
To ensure the best sealing possible of the loop, replace the cap with
another one that perfectly matches the original: same shape and diameter
•
Every time you operate on the A/C loop, make a visual check of the caps
•
Protect the caps with a safety seal (Ref. 699938)
