WARNING
The equipment described in this manual is designed to operate with
LP-gas, a flammable fuel under pressure. The nature of the
application involves inherent hazards that could result in injury.
ONLY a trained and fully qualified person should service this
equipment.
WARNING
Apply a liberal amount of soap/water solution to all external
threaded and flanged connections. Check for leaks by observing
new bubble formation in the soap/water solution. Repair any leaks
and retest before opening downstream valves to consuming
equipment.
PERIODIC DRAINING
During normal operation the FILTAIRE should be drained periodically to remove
the material deposited in the bottom. The schedule for draining depends on the
quality of LPG gas and the usage of the entire system. Those using the system
must establish the draining schedule. A general rule of thumb used to help
establish the draining schedule is to measure the amount of heavy end
hydrocarbons drained after the initial one week of normal operation. Based on
the amount drained after one week, the schedule should be adjusted so that the
total amount of collected heavy end hydrocarbons does not exceed the maximum
amount outlined in Table 1 below.
EXAMPLE:
After the first week of normal operation, an F12 FILTAIRE was isolated and
drained. The total amount of drained heavy end hydrocarbons was measured to
be 1L (0.26 US Gallons). Based on the measured amount, periodic draining
should be performed at least once in 6 weeks to ensure that the amount of
collected heavy end hydrocarbons does not exceed the maximum amount of 6L
(1.6 US Gallons) from Table 1.
