1. Most refrigerants are heavier than air and sink to the floor or
accumulate in low areas.
2. Place the instrument in an area that provides it with a
representative sample; ventilation Smoke Tubes (P/N 458480) are
useful in determining air flow patterns in ambient sampling areas.
3. Ensure that the area around the instrument is unobstructed to
allow the sample to flow freely to the instrument.
4. If the unit’s visual indication is used to alert workers of potential
gas hazards, mount the instrument in a clearly visible location.
NOTE: The diffusion unit is appropriate for applications where the
indication panel is clearly visible with the unit mounted 12-18
inches off the floor; otherwise, a pumped unit located at eye
level with sensor points located 12-18 inches off the floor may
be more appropriate.
Mounting the Unit
Five Rules for Proper Mounting
1. Do not mount the unit to structures subject to vibration and shock.
2. Do not locate the unit near an excessive heat source.
3. For proper cooling, allow at least three inches of clearance around
all surfaces, except for the mounting surface.
4. Do not mount the unit where it will be exposed to direct solar
heating, rain and splashing water.
5. Mount the unit where it is accessible for maintenance.
Mounting
Do not mount more than one pumped unit to the same mounting
structure. Mechanical vibration produced from one unit can cause
improper gas readings on another unit.
Do not locate these units in an area that may contain a flammable mixture
of gas and air; otherwise, an explosion may occur.
Install the Chillgard LS Refrigerant Infrared Monitor in the area where a
refrigerant is anticipated or control of the gas is desired.
Ventilation Smoke Tubes (P/N 458480) are useful in determining air flow
patterns in ambient sampling areas.
