Ensure proper sized crimping head is selected.

Open jaws and place over stainless steel crimp

sleeve, positioning tightly against the plastic isolation

collar. Keeping the tool perpendicular to the fitting and

properly positioned, complete crimp using manual or

power crimping tools. Ensure that the jaws of the

crimping tool come together completely.

NOTE: IT IS IMPERATIVE FOR THE TOOL TO BE

POSITIONED PROPERLY. IMPROPERLY PLACED TOOL

COULD LEAD TO AN INCOMPLETE SEAL OF FITTING.

Remove tool from crimped connection and

inspect for three circumferential indentations

on the stainless crimping sleeve.

After completion of the crimp, proper pressure

testing procedures should be followed to check

for leaks. As per ASHRAE guidelines, a proper vacuum

should be performed on the system to ensure system

is free of moisture and contaminants.

Pro Tip: Due to the tolerances involved in the crimped

fitting connection, it is recommended to pressure test to

400 PSI on air conditioning-only systems and 600 PSI

on heat pumps to identify leaks immediately.

It is important that a proper vacuum is pulled and that the system is pressure tested to

detect leaks immediately. As with any R-410a system, introduction of air and contaminants

can lead to premature failure of equipment and potentially the pipe itself. When installed

correctly you can be assured of a line set system that will meet and exceed the

performance standards of a traditional line set. Thank you for using Yoga Pipe.
