MISE EN GARDE
Le gaz sec inerte doit passer par le système pendant le brasage afin de
prévenir l’entartrage et l’oxydation. Le tartre et les oxydes peuvent bloquer
les éléments de réfrigération et causer une défaillance du système.
Pipe Supports:
All tubing should be supported in a least two locations (near the end of each tubing run).
Long runs will require additional support. As a guide, support 3/8” to 7/8” pipe every five
feet, 1-1/8” to 1-3/8” every seven feet, and 1-5/8” to 2-1/8” every ten feet. Do not leave
a corner unsupported when changing directions. Place supports within 2 feet of each
direction change. Piping that is attached to a vibrating object (such as a compressor or
compressor base) must be supported in a manner that will not restrict the movement of
the vibrating object. Rigid mounting will fatigue the tubing causing refrigerant leaks.
Oil Traps:
To ensure proper oil return to the compressor, a P-type oil trap should be installed at
the base of each suction riser of four feet or more. The suction trap must be the same
size as the suction line. Additional traps are necessary for long vertical risers. Add a
trap for each length of pipe (approximately 20 feet) to insure proper oil return. Suction
lines must slope ¼” per 10 feet toward the compressor. Install a suction line trap at the
evaporator outlet if the suction line rises to a point higher than the connection on the
evaporator.
CAUTION
Failure to properly install oil traps can prevent sufficient oil return to the compressor
resulting in premature compressor failure.
MISE EN GARDE
L’installation incorrecte des siphons d’huile peut empêcher un retour d’huile
suffisant au compresseur, entraînant une défaillance prématurée du
compresseur.
