!
While wearing protective eye wear, inspect HVAC system for any ultraviolet light leakage. No
ultraviolet light should be visible from any duct opening, joint, seam, or the unit itself.
Use an
ultraviolet resistant gasket if needed.
The installation should also be inspected using a sensitive
ultraviolet meter, to ensure that the ultraviolet radiant exposure of personnel/occupants is within
acceptable limits.
20. If necessary, seal any openings, joints, seams, etc. using aluminum tape or equivalent ultraviolet resistant material.
PRECAUTIONS
To guard against injury, basic safety precautions should be observed.
!
WARNING
•
Procedures MUST be adopted to ensure that the Air Duct Disinfection Unit is disconnected from power whenever
personnel work on the HVAC system. Personnel who work in and around the system
MUST
be briefed on the
precautions to be observed.
•
The HVAC system
MUST
be re-inspected routinely for any ultraviolet light leakage. (Especially when maintenance
or modifications are performed.)
•
If there are any doubts or concerns about the safety or the effectiveness of the installation, or if a sensitive
ultraviolet meter is required, please contact our Application Specialists.
MAINTENANCE
Always disconnect power to the unit before performing any service or maintenance.
!
WARNING
•
The
Air Duct Disinfection Unit
is designed to operate with a minimal amount of maintenance.
•
A regular cleaning cycle of the
germicidal lamps and
sight glass should be established,
and carefully maintained, based on inspection and experience. The frequency of cleaning will vary with the
conditions surrounding each installation. It is recommended that the ultraviolet lamps be cleaned at least once
every three (3) months.
•
The germicidal ultraviolet lamps used in the
Air Duct Disinfection Unit
have a manufacturer’s rated effective life
of 1
0
,000 hours. Lamps may operate longer than the rated effective life, but the reduction in ultraviolet output
will make it impractical to use past the manufacturer’s rated life. For maximum efficiency lamp replacement is
recommended every 1
0
,000 hours of operation or about one (1) year of continuous use.
•
Unless lamp replacement is due to failure or breakage, it is recommended that all lamps be replaced at the
same time.
