Note: It may be necessary to secure the capillary to
a bracket or brace to quiet the vibration. The capillary
may need to be secured in more than one place.
DIRECTION OF
VIBRATION
Figure 3: SEC99 Loose Coil Perpendicular
Arrangement
Note: You may require a double coil arrangement if
vibration in different directions is present. Use a
bracket or brace between the coils, if necessary.
After considering the vibration effect, follow these
instructions to install an SEC99 Series UltraCap or
UltraTube:
1. Uncoil the capillary or tube as needed (Figure 4).
2. Hand-start the flare nuts to avoid damaging the
fitting threads.
Note: If the fitting flare nut cannot be tightened onto
the male flare fitting, it may be necessary to remove
the Schrader valve depressor. See Removing the
Breakaway Schrader Valve Depressor on page 2.
3. Use a 5/8 in. wrench to tighten the flare nuts. Do
not apply more than 10 lb·ft (13.6 N·m) of torque.
4. Check all fittings and connections for leaks before
placing the system into operation.

!
CAUTION: Risk of Environmental and
Property Damage
Avoid sharp bends in capillary tubes. Sharp bends
can weaken or kink capillary tubes, which may result
in refrigerant leaks or restrictions of flow.
!
CAUTION: Risk of Environmental and
Property Damage
Coil and secure excess capillary tubing away from
contact with sharp or abrasive objects or surfaces.
Vibration or sharp or abrasive objects in contact with
capillary tubes can cause damage that may result in
refrigerant leaks, which may result in damage to the
environment or property.
o
90 Fitting
Interior diameter of coiled capillary must be
at least 2 in. (50 mm) for SEC99A UltraCap and
at least 4 in. (102 mm) for SEC99B UltraTube.
Figure 4: SEC99 Installation Requirements
Note: A bracket or brace may be required depending
on vibration.
Removing the Breakaway Schrader Valve
Depressor
If you cannot hand tighten the SEC99 flare nut onto
the male flare fitting, remove the snap-off Schrader
valve depressor as follows:
5. Insert the tip of a pair of needle-nose pliers as
shown in Figure 5.
6. Apply firm pressure to snap off the Schrader valve
depressor.
