2) Remove 1 screw from the bottom frame (and 1 screw from the left frame for type D models) so that the plates of
the
drain pan heater can be inserted under the heat exchanger with ease.
3) Lift up the heat exchanger, and insert the plates of the drain pan heater under the heat exchanger.
• The ground plate of the
drain pan heater should be installed so that, in type A models, it firmly adheres to the
bottom frame and, in type B and C models, it firmly adheres to the partition plate.
• Install the drain pan heater in a position where it does not come into contact with the fan motor base.
4) If there are no holes, drill ɸ1/8 inch (ɸ3.2mm) holes in the bottom frame or the partition plate
(model type dependent) to fix the
drain pan heater.
• Place the actual components to ensure positioning is correct before drilling holes.
• The holes can be made with the included piercing-screw as well.
5) Fix the
drain pan heater with the piercing screws.
6) Reattach the screw that was removed from the bottom frame (as well as the screw that was removed from the left
frame for type D models).
