Penn SEC99A Instructions D'installation

and SEC99B UltraTube Armored Tubing
Application
!
CAUTION: Risk of Personal Injury and
Environmental Damage.
Do not use the SEC99A UltraCap or SEC99B
UltraTube in applications that expose the UltraCap
or UltraTube assembly to ammonia or any other
substance that is corrosive to copper or brass.
Corrosion of the copper or brass components can
result in the discharge of refrigerant that is under
pressure, which can cause personal injury and
environmental damage.
MISE EN GARDE : Risque de blessure et
dommages environnementaux.
Ne pas utiliser le SEC99A UltraCap ou SEC99B
UltraTube dans des applications exposant le
système UltraCap ou UltraTube à de l'ammoniac ou
à toute autre substance corrosive pour le cuivre ou
le laiton. La corrosion des composants en cuivre ou
en laiton peut entraîner une fuite de réfrigérant sous
pression, susceptible de provoquer des blessures et
des dommages environnementaux.
The SEC99 Series UltraCap and UltraTube provide a
means to make pressure connections for refrigeration
and air conditioning applications. The SEC99 models
are compatible with all common noncorrosive
refrigerants. Several models and styles are available.
See Table 1.
The SEC99A UltraCap has a capillary tube that
minimizes pressure pulsation. The SEC99A UltraCap
has brass-colored flare nuts on the fitting connectors.
The SEC99B UltraTube has a 1/4 in. tube that allows
more fluid flow. The SEC99B UltraTube has
silver-colored flare nuts on the fitting connectors.
The brass-armored sleeve on all SEC99 Series
models provides resistance to abrasion and facilitates
routing, coiling, or bending of the capillary or tube. The
copper capillary or tube inside the armored sleeve
does not effuse refrigerant to the environment. Some
models have a breakaway Integral Schrader® valve
depressor in the flare fitting.

SEC99A UltraCap Armored Capillary
Installation Instructions SEC99 Series
Installation
The SEC99A Ultra Cap provides a means to make
pressure connections for refrigeration and air
conditioning equipment. Inherent in all heating,
ventilating, air conditioning, and refrigeration
equipment systems is vibration caused by
compressors, fans, and other reciprocating and
rotating equipment. Vibration must be taken into
account when installing the SEC99. If you do not
address the effect of vibration and subject the capillary
to adverse vibration, the capillary will fail (break).
Vibration varies from equipment to equipment;
however, there are some general guidelines to follow
that help minimize the effects of vibration on the
capillary:
•
Install the capillary as far as possible from
reciprocating compressors. The liquid line is
recommended when making high side pressure
connections.
•
Install the capillary so that it moves in the same
direction as the vibration. See Figure 1.
•
Often damaging vibration can be dampered in a
loose coil arrangement. See Figure 2.
•
Sometimes two loose coil perpendicular
arrangements may be required to dampen
vibration from opposite directions. See Figure 3.
•
Neatly coil and secure any excess capillary where
open coil installation is not necessary.
•
Do not allow the coils of the capillary to rub
together or rub against any other object.
