6. Maintenance, Inspection, and Repair
6.1 Cautions for Maintenance, Inspection, and Repair
When requesting the manufacturer’s service division for disassembly and repair,
always enter the details of the type of gas used in the pump on the Pump Usage
Checksheet. If the pump has been used for discharge of a toxic gas it will be
contaminated, and may not be able to be disassembled and repaired in some cases.
* Ensure that the pump is dismantled and repaired only by qualified repair technicians.
+ 1 A qualified repair technician has received the appropriate training from the
manufacturer.
* The customer is able to conduct only the following maintenance and repairs. Do not
conduct any other repairs, or modifications other than the manufacturer's standard
options.
1) Replacing diaphragms
2) Replacing valves
3) Replacing non-return valves
4) Replacing O-rings
5) Replacing head gaskets
* Always remove the power cord before replacing consumables.
* When replacing diaphragms and valves, always wear a dust mask and gloves to
prevent ingestion of fine particles resulting from wear of the components.
* This pump operates with extremely fine clearances, and therefore requires
considerable skill in assembly. If a qualified repair technician is not available,
replacement of consumables should be left to the manufacturer's service division.
6.2 Maintenance
The following checks are required at least once every three days during operation.
1) Check for abnormal noises.
2) Check for abnormal heating of the pump.
3) Check that gas is discharged normally.
If a problem is found, take the measures described in 6.5 Troubleshooting List.
