Maintenance
Changing EC Fans
The fans are designed as plug and play “hot swap” enabling the fans to be changed
without the need to disconnect the power from the entire unit.
Removing the 4 security fixings enable the fan to be removed
The unit has automatic disconnect sockets to the fan motors. The remaining fans will
increase speed to compensate for the fan being serviced (only in N+1 configuration)
CAUTION
The unit will remain live up to the fan disconnect socket.
Ensure that the fan stops rotating before placing hand near blades.
2 or 3 Way Chilled
Water Regulating

secure fixing to the valve body. The actuator is located onto the valve body by four pegs
that are secured by a torque screw through the adjustment handle.
Coil Guard Cleaning
The coil guard must be cleaned periodically. Carefully removing any debris.
Be careful not to damage the temperature sensors.
CAUTION
When cleaning the coil guard, extreme care must be taken to ensure that the coil
does not get damaged.
