Annual Maintenance Requi re ments:
Component Action Required
Inlet strainer Remove plug and clean the screen. Replace screen if gaps or holes are present
in the screen. If oils or contaminants are present, it may be necessary to use a
cleaner to remove them. If magnetic plug is installed in the strainer, clean any
debris off the plug using a lint-free rag.
Inlet solenoid valve Perform a leak test of the valve according to procedure on page 6-39. If no leak
is observed, continue to use the valve as-is. If a leak is observed, change
solenoid valve diaphragm and internal component using recommended repair kit
for the inlet solenoid valve (see spare parts list for proper part number). Refer to
the maintenance and operation information for ASCO 2-way valves included in
the Appendix section. Replace solenoid valve if the valve body is damaged.
NOTE: Install kit if the valve makes unusual noise (chatter or buzzing) during
normal operation regardless if leak is present.
Liqui-SAFE
TM
valve Conduct performance check as described on page 5-25. If valve does not pass
leak test, replace all O-rings in the Liqui-SAFE
TM
valve provided in the repair kit.
If valve does not pass latch test, replace Liqui-SAFE
TM
valve assembly. (see
spare parts list for part numbers).
Relief Valve Visually check and replace if leaks are observed. Check for excessive corrosion
and ensure the relief valve is covered with the appropriate rain cap to prevent
rain and debris from entering the valve. Replace rain cap if not present or
damaged. Relief valve should be replaced per the manufacturers’
recommended replacement date or if it relieves during normal operation.
Electronic wiring and
connections
Check primary terminal lug tension and visually inspect all electrical connections
for corrosion, loose wires, heat build-up and/or charring. Tighten or replace if
necessary.
Heat exchanger &
system drip legs
Check the system drip legs and vaporizer for heavy ends and oil build-ups. If
present, first ensure there are no sources of ignition within 25 feet (7.6 m), then
drain heavy ends. NOTE: In areas where LPG quality is poor it may be
necessary for the drip legs and heat exchanger to be checked for heavy ends
more frequently (monthly or bi-monthly depending on quality of LPG). Once it is
verified no significant quantity of heavy ends is accumulating during vaporizer
operation, this maintenance can be performed on an annual basis.
