2. The outdoor coil is protected by an inner mesh screen
and a wire cage (see figure 25). If debris has collected
between the mesh screen and the coil and cannot be
dislodged by spraying unpressurized water from
inside coil surface to the outside, the mesh may be
removed by first removing the top of the unit which will
allow for removal of the wire cage.
3. Then, using pliers to grip the head of the push pins, pull
straight out to extract the push pins along one side of
the coil. If necessary, remove the push pins along the
back of the unit; it is usually unnecessary to fully
remove the inner mesh screen.
4. Drape the mesh screen back and wash the coil. When
all the debris has been removed from the coil, reinstall
the mesh screen by positioning it in its original position
and reinserting the push pin. No tool is required to
push the pin back into the same slot in the fins.
5. If the push pin is loose and tends not to stay in place,
brush the fins with a fin brush (22 fins/in). Line up the
push pin a couple fins to the right or left of the original
hole and re−insert the pin.
