T.1 Protective measures and additional protective measures
Adjustment and maintenance must be done by skilled technicians usually based on service contracts for some years
or long-term ESCO contracts.
The units are provided with lockable doors to avoid unintended hazards and injury because of rotating parts in the unit.
The potential sources of harm are the fans with fast rotating impellers. Hazards from the impellers are obvious during
operation, but when power is cut-off, the impellers are still potential hazards due to after-run for at least 20 seconds.
Notice that even cut-off the impellers are still potential hazards.
Other motor-driven parts are dampers with damper motors and rotary heat exchangers, but the movement is so slow
that guard measures are not necessary. Just keep your hands away from places with risk of injury.
Use particulate respirator when filters are replaced.
T.1.1 Necessary protection measures prior to start-up
Ensure that all protection measures are installed correct before start-up.
T.1.1.1 Design of protection measures
Lockable doors can be unlocked only by use of tools.
T.1.1.2 Configuration of frequency converters
A frequency converter is mounted beside the fan in some units. If the configuration of frequency is carried out with the
fan in operation for safety reasons a long cable must be installed between the frequency converter inside the unit and
the control panel outside the unit.
T.1.2 Safe adjustment and maintenance
Before maintenance and repair, the unit must be turned off by rotating the main power switch to OFF position. Note
that lamps must be switched on during maintenance (lamps are an accessory only installed, if ordered).
Use cut-resistant gloves for protection against injury from sharp metal plate edges. Use CE-marked gloves for this pur-
pose. Use helmet during maintenance work in the unit.
T.1.3 Personal protective equipment for maintenance staff health and safety
Use the below-mentioned personal protective equipment for maintenance:
