12. Maintenance
Disconnect the device from power supply before maintenance or repairs.
Only carry out maintenance and repair in complete device standstill and pressureless condition.
Check the surface temperature of the device to avoid the risk of burns by radiant heat. Wear heat-resistant gloves
and safety goggles!
Clean soiled or contaminated surfaces before maintenance, wearing protective equipment if necessary!
Secure the device against recommissioning during maintenance and repair work!
12.1 General maintenance
• Retighten all fittings 6 weeks after start up!
• Check all components for leakages and damage at least every four weeks!
If leakages are not repaired, lubricant might escape under high pressure. Remove possible puddles of lubricant
immediately.
12.2 Change of lubricant and cartridge
Always observe cleanliness when changing the cartridge!
• Check the level regularly, if necessary insert a new cartridge as described in chapter 9.”Start-up“!
• Change the lubricant according to the specifications of the lubricant manufacturer. Environmental influences like increased
temperature or pollution may shorten these intervals!
• Please make sure to only use lubricants that are suitable for the device as well as the lubricated machine and that comply with the
requirements of the particular operating conditions (see also lubricant release list FFG_002_ZEPTO)!
• In case of different lubricant manufacturers, ensure that the lubricant quality corresponds to the quality of the previously used
one! As precautionary measure, drain the lubricant reservoir properly and clean it!
12.3 Change of the non-return valve
When aggressive lubricants are used, it can happen that the seal in the non-return valve of the pump element wears faster and
becomes leaky. The device no longer builds up pressure.
In this case, the non-return valve can be changed using an assembly kit (see chapter 17. “Spare parts”).
The relevant manual for changing the non-return valve is included in the assembly kit.
13. Shutdown
• Relieve the device from pressure!
• Turn off power supply!
• A qualified electrician has to disconnect electrical components from the power supply!
• Remove all pipes and hoses from the device and loosen all fastenings for disassembly!
14. Disposal
Observe the disposal instructions of the lubricant manufacturer when lubricant is changed! Lubricants
or cloths contaminated with lubricant, etc. must be collected in specially marked reservoirs and
disposed of accordingly.
Disposal of the device and the cartridges must be done properly and professionally and according to
the national and international laws and regulations.
