lid is closed in humid conditions. It is not adequate for protecting the unit over time if a
continuous leak is present in the enclosure.
Sealing the Register is the Responsibility of the Installer
There is no product warranty coverage for any water or moisture damage to the Register
that results from improper sealing.
1. Conduit Entrances
The Register housing has 11 conduit entrances, all are ½" NPT female threads. Use only ½"
NPT male threaded fittings on the conduit entrances. Thread sealant must be used with NPT
threads. Pressed-in Caplugs or straight (rather than tapered) threads are inadequate for
sealing these entrances. Acceptable fittings include metal or plastic conduit, pipe plugs, or
cable glands.
Apply PTFE-based "pipe dope" to threads, or wind a minimum of two revolutions of PTFE tape
prior to installation. Engage the threads with a minimum of four full turns.When using cable
glands, ensure that the gland is sized properly for the outside diameter of the cable and the
elastometric seal around the cable sheath is compressed onto the cable. Use only one cable
per cable gland, unless the gland accommodates for multiple cables. When using conduit or
Liquid-Tite, ensure that the opposite end is connected to an environmentally sealed device. If
the conduit is not sealed at the other device, fill the interior of the conduit at the Register with a
silicone rubber sealant–such as RTV–to prevent moisture from running down the conduit into
the enclosure.
2. Cover Seals
To seal the Register cover properly, ensure that the O-ring surrounding the cover is fit snug
inside the groove, and securely tighten the cover screws.
3. Shaft Seals
Units with internal pulsers have an O-ring around under the pulser inside the enclosure, and
also a pulse encoder drive shaft that extends through the bottom of the Register housing. If a
drive shaft adapter was attached at installation, ensure the O-ring around the shaft is securely
