unobstructed location.
Installation
- Choose the correct position for the valve/s.
- Cut a square hole in the freezer wall. The cutout must allow for clearance of the heating element.
- Remove the tapes that have held the flaps secure during transit.
- Fit the valve body section (top indicated) to the wall, ensuring the flange face is sealed around the cutout with silicon beading and fixed through the 2 holes in the centre line of the flange face with the supplied screws. Ensure the body is level in both directions.
- Electrical connection to be carried out by a registered electrician. Connect the 240 volt supply and test the heater coil. (0.230 amps initial start)
- Depending on the panel thickness, trim the rear flange section to length and fix to the wall through the 2 holes in the centre of the flange. Again, ensuring the flange face is sealed around the cutout with silicon and is level.
- Remove the valve flap fixing screw, before fitting grille.
- Fit the protection grille through the 4 mounting holes with the supplied screws.
