Installation
The following applies to system design:
1)
The sensor box is installed on the frame of the evaporator.
2)
Ground wire should be connected to the frame with a stainless screw.
3)
The wire must be placed between the fins in the air inlet side, or where ice build-up occurs.
The wire can be fixed with a special HBDF wire-clips or standard nylon (PA6) wire strips.
4)
The temperature sensor must be mounted between the fins at the bottom of the evaporator
section (to measure when all the ice has melted).
5)
Normally installed with a standard unshielded cable. If the EMC is higher than described in
EN 61326, a shielded cable must be used.
Note:
To have a proper ground connection, we recommend using stainless screw with a star washer/disc and cover/applying
silicone grease/compound around the connection to avoid corrosion.
