Maintenance

For service and technical support, please contact AB Ph. Nederman & Co.
Make sure the inside of the hose reel and the connection pipes are free from
deposits. Build up of deposits inside the piping system may cause discharge of
static electricity.
Make sure the outside of the hose reel are free from dust layers.
Oily and sticky substances can sometimes stick to the damper blade resulting
in jamming so that the damper does not close completely. The reel must then
be dismantled for cleaning.

Service and maintenance of ATEX equipment

To ensure the required level of protection with regards to the equipment
category, check the following points:
• Ensure that the Vacuum hose reel is regularly inspected for damage or
malfunction. If the vacuum hose reel is damaged it must be repaired
immediately.
• Ensure that no explosive atmosphere and/or dust layers are present
when cleaning, servicing or inspecting the hose reel.
• Ensure that only original (OEM) spare parts are used.
• Ensure that the reel is not covered with thick dust layers (>5 mm). This is
prevented by setting up routines for regular cleaning and including these
in the explosion protection document.
NOTE! The ATEX classification is only valid when Nederman spare parts are
used.
