GAI-Tronics recommends the following precautionary steps to protect the unit during installation:
1. Install this unit using appropriate Div. 2 wiring methods.
2. To ensure that the unit is vandal-resistant, run the subscriber line inside conduit.
3. Use the conduit entry located on the bottom of the enclosure to prevent any condensation forming
inside the conduit from dripping into the unit. Additionally, using the bottom conduit entry makes
water less likely to enter the unit at the conduit connection points.
4. Use Teflon™ pipe joint tape or a thread sealing compound around the conduit threads to seal threaded
connections and prevent water from entering into the unit at the conduit location.
5. Apply a small amount of silicone sealant inside and around the end of the conduit pipe that is inside
the unit. The sealant helps to prevent any condensation formed inside the conduit from dripping into
the unit. This is especially important when using the conduit entry located on the top of the
enclosure. (Manufacturers of silicon sealant include: Dow Corning, Duron, General Electric, and
DuPont.)
6. Sealed fittings should be installed at all cable entry points to prevent liquids from entering the unit.
