This section defines Thermo King’s requirements for fabricating and installing refrigeration hoses and fittings onto
vehicle powered truck units. Following these standards will result in a system that operates as designed.
Hose Layout and Design
Determining ahead of time which types of fittings to use, best hose routing, along with obstacles to avoid, will go a long
way towards a successful installation.
Before routing refrigeration hoses, refer to the unit specific installation manual to determine how many, and which size
hoses will be connected to each of the units components. In most installations, two of the same size hoses will be run to
the same area (i.e., liquid line and defrost line are both #6 hose). In this case, it is mandatory to label each of the hoses
to identify which component they connect to. This is important to avoid confusion when making the hose connections.

•
Always label similar size hoses to identify which component they connect to.
•
All hose ends must be capped or taped off during installation to prevent contamination and moisture buildup which
reduces system pump down time.
•
Always keep the holding charge in the condenser and evaporator until hoses have been routed and are ready to be
connected to the components.
