Fluorescent Leak Detection; Fluorescent Dye Injection - New Holland T8010 Manual

Fluorescent Leak Detection

Flu or e s ce nt t rac er or dye s ol uti o ns ar e now
commonly used to detect refrigerant leaks. Your MX
tractor had an ultraviolet fluorescent tracer or dye
introduced into the A/C system at the time of
manufacture. This dye will glow a bright yellow/green
at a leak location under ultraviolet light.
The dye has been tested for compatibility with
HFC-134a systems and approved for use in all New
Holland HFC-134a A/C systems. Special tools are
also available to aid in injection and leak detection.
See SPECIAL TOOLS, page 4 in this Section.

Fluorescent Dye Injection

Many methods are available to introduce the dye to a
system for the first time or to reinject the dye into an
A/C system. Select the method most appropriate to
the needs of the A/C system and where you are in
the service process:
1. Recovery Station Dye Injector Tool with a
System in a Vacuum
2. Recovery Station Dye Injector Tool with a
Charged System
3. Quick and Easy Dye Injector Tool with a
Charged System
4. Compressor Oil Port
5. SP-20 PAG Oil Return Bottle
Section 50 - Climate Control - Chapter 2
50-2-53
The dye, which dissolves into the SP-20 PAG oil in
the system, is par ticularly helpful in detecting
intermittent leaks that occur only when the system is
running because of change of temperature, high
system pressures, vibration or contact between
components.
WARNING: Wear safety goggles and non-
!
permeable gloves when working with the
fluorescent dye and leak testing.
This fluorescent dye will normally remain useful over
the life of the system. However, due to a large
refrigerant leak, system flush or major component
failure, it may become necessary to reintroduce the
dye into the refrigerant circuit.
