CAUTION:
When front controller door is open it sits on two hinges on the left hand side of the
controller. (Picture 3) Please take extra care when operating with an open front door. Do not push
the front lid upwards without holding onto the door, as this could detach the door from the support
hinges. Always close the front panel on completion of maintenance work and fasten screws.
Note:
Please ensure the O-ring is in good condition and seated properly within the groove.
