Preventing Condensation
Condensation may be eliminated by following
instructions within this guide and observing the
following cautions.
CAUTION: Even small leaks must be
prevented as they can increase humidity
inside the housing.
DO NOT use over seals such as RTV
and silicone caulks.
Ensure fans spin when power is on.
If possible, mount the housing so the
least needed view (such as a wall,
building corner, or pole) is opposite the
fan/heater assembly.
Problems that Can Cause Condensation
Damage, missing parts, or procedures
that most often allow water to enter the housing are
as follows (refer to figures opposite):
 Mounts that allow water to enter the air path. If
an older horizontal mount is used, replace it
with a new model or ensure there is ample
slope away from the camera dome and a foam
plug is present
 Missing foam seal from entry into the pipe of
the mounting structure
 Missing O-ring on end cap, or missing sleeve
or gasket on pipe adapter
 Missing Teflon tape around any housing pipe
threads
 RTV or similar sealant covering an air path
 Loose nuts (4) at the top of the housing
 Heater fans not turning
 Bent flange on metal housing that
compromises the gasket seal between the
bubble and the housing
 Plugged drain holes in the bubble trim ring
 Cracked bubble
 Tamperproof screws that are missing or
improperly tightened compromise the gasket
seal between the bubble and the housing.
