Maintaining Motor Bearings
Bearings are sealed for life and do not
require periodic lubrication.
Cleaning Coil
A clogged or dirty coil will reduce the cooling
capacity. Clean coil by completing the
follwing steps:
1. Turn off the electrical power source and
allow the rotating fan wheel to stop. Then
disconnect the power source wires from
the terminal strip to ensure safety.
2. Follow the “Changing Entire Fan Board”
procedures to remove the fan board.
3.Clean the coil through the opening for the
fan discharge on the discharge panel.
4. Clean coil:
• Clean coil by brushig fins with a stiff
nylon brush.
• Then clean coil with a vacuum cleaner.
• Coil may also be cleaned by using a
high pressure air hose and nozzle, if a
compressed air source is available.
• Straighten any bent fins.
5. Re-install the fan board and fasten all
necessary screws.
6. Re-connect the electrical power source.
lt should be pointed out that if the air filter is
used and taken care of properly, the coils
will not need cleaning.
Cleaning Drain Pan
The drain pan should be cleaned to allow
condensate flow. lf it is clogged, steps
should be taken to clear the debris so that
condensate will flow out easily.
Drain Pan Leveling
The drain pan is levelable independenly of
the fan coil unit. This allows it to be leveled
easily and fast, as well as to pitch it to a
maximum angle to accelerate drainage.
Follow the steps to adjust the slope of the
drain pan:
1. Loosen nuts which fasten the drain- pan
suspension screw with unit casing
together.
2. Using wrench to turn the two M6x50
suspension screws located at the drain
side to adjust the slope of the drain pan,
as shown on Figure 13-L. Turn these two
screws clockwise will raise the drain side.
Turn conter clockwise will decline the
drain side to accelerate drainage.
3. After adjust the drain pan to proper slope,
retighten the nuts loosened at step 1 to
fasten the suspension screw with drain
pan and unit casing.
Changing Drain Pan
To remove or change the drain pan,
complete the following steps:
1. Loosen two nuts, on each suspension
screw, which fasten suspension screw
with unit casing and with drain pan bracket
together, as shown on Figure 13-K.
2. Turn all suspension screws counter
clockwise until remove from the bracket.
Then the drain pan will be separated from
the unit.
CAUTION: Due to the dimensions of the
drain pan, two installers are
recommended to do this step for safety.
3. Follow the opposite procedures to re-
install the drain pan.
4. Level the drain pan after re-install. Make
sure the drain pan is pitched properly for
condensate drainage.
