Operating instructions
4 Maintenance
4.1 Checking the door unit
Power-operated doors have to be tested by a qualified individual at least once a
year.
Power-operated doors on escape and emergency routes have to be tested by a
qualified individual at least twice a year.
The test is carried out according to the supplied inspection log for power-operated
doors.
Between tests by a qualified individual, it is recommended as an additional safety
precaution that a regular inspection of the key functional elements be performed
by the facility operator.
4.2 Wear parts
WARNING!
Using the wrong replacement parts can cause a risk of injury!
The use of incorrect or faulty replacement parts can be dangerous to
personnel.
• Only use replacement parts approved by dormakaba.
The replacement of wear parts depends on the expected number of load changes
made by the door unit. ESPROLINE sliding door operators are tested on approval
with 1 or 1.5 million opening and closing cycles. However, during operation the door
units are subjected to other environmental conditions and a natural ageing
process. As such, dormakaba prescribes timings for the replacement of safety-
related wear parts in order to ensure safe operation of the door unit.
