5.0 General Maintenance
5.1 General Safety Precautions
A safe operation is critical for the safety of the staff and customers. Read and comprehend following
recommendations:
Do not allow pumpers to use damaged/broken components like hose assembly.
Prevent them from using dispensers with open or missing caps.
Place an explicit and comprehensible operation instructions on the dispensers.
5.2 Preventive Maintenance
Consider the safety precautions specified in the Section 1.3 when conducting any maintenance on the
dispenser. As long as the maintenance of a correctly installed dispenser is done appropriately and
regularly, it rarely needs an emergency service.
Perform following inspections regularly.
Keep the dispenser clean at all times. Apply a non-abrasive, silicon based polish at least 4 times a
year, in order to maintain glossy looks and prevent corrosion on all stainless steel parts. Painted parts
may be applied with a regular automobile polish. Application intervals may be adjusted in accordance
with climate and regional conditions.
Wipe dusty and dirty areas regularly with a soft cloth. Do not use excessive water.
Check all LPG carrier parts like hose, break-away and nozzle against possible leaks and damages.
If you detect damage on the hose assembly, immediately cease to use the dispenser.
Continuing to operate it may result in personal injury and property loss. Close all valves
and fix hose assembly.
Check for sharp edges that may cause slashes on the casing.
Check hydraulics for leakage.
If you detect damage on the hose assembly, immediately cease to use the dispenser.
Continuing to operate it may result in personal injury and property loss. Close all valves
and fix the leakage. (See Section 2.4)
As the LPG taken from the refinery may contain water, dirt and aggressive hydrocarbons, check the
tank regularly. Contaminated LPG may cause serious damage in the dispenser. (See Section 1.1)
Use only genuine spare parts provided by Yenen on the dispenser. Using spare parts other than
genuine Yenen spare parts may impose safety risks and therefore shall violate all obtained
permissions and warranty.
5.3 Filter
Generally speaking, a clogged filter shall slow down the flow rate. For new installations, it may be
necessary to replace filter several times within the first week of operation, as there may be some
debris and pipe insulation parts left from the installation.
Depending on the quality of gas, the filter should be replaced for every 1 million liters, 6 months or if
flow rate slows down.
A 2 bar or more difference at the pump outlet and dispenser liquid line during the operation of the
dispenser and pump indicates that the filter is clogged.
Read Yenen’s filter replacement instructions. ITL-SRV-7.5.1-008
