DANGER
!
WARNING
• Use installation wires rated for 75oC and above.
• The TG Series (the equipment covered by the IFU) has not
been tested for Life Safety Applications and are not to be used
in Life Safety Applications in jurisdictions that require this
certification.
• Only qualified trade installers should install, program,
maintain and test system incorporated therein. Installer is
responsible for compliance of all applicable codes.
• Read, understand, and follow instructions thoroughly.
• The unit and associated systems require routine test and
maintenance as prescribed in the TG Series User's Manual
section 'Periodic Test and Maintenance'
• Do not install in hazardous or classified locations.
• De-energize power supply prior to installation.
• Gas sensors should not be used as a substitute for proper
installation, use, or maintenance of gas emitting equipment.
• This device is designed to detect conditions that could
result in acute effects of gas exposure. It will not fully safeguard
individuals with specific medical conditions. If in doubt,
consult a medical practitioner.
• Conduit is prone to condensation if it passes from one
temperature zone to another, such as from indoors to outdoors
or from one part of a building to another. This condensation
may actually drip into the sensor if mounted below, causing
damage and/or poor readings.
In order to prevent condensation and water egress, seal
both the top and bottom of the conduit with a suitable
expanding foam product (such as Polywater
50KIT1) to prevent warm air from entering cold conduit.
Alternatively, fiberglass insulation may be inserted in the
conduit between the cold and warm sections using a rigid wire
or other method if both ends cannot be sealed. Sealing is the
preferred method.
• Conduit air flow entering sensor may prevent sensor from
reading ambient air properly, resulting in under measurement
of gases. Plug sensor conduit in all installations with a foam
plug or seal as noted above in order to prevent airflow from
the conduit.
LIMITATION OF LIABILITY
Senva's liability, whether in contract, in tort, under any
warranty, in negligence or otherwise shall not exceed the
