HARBOR POINT WALL SPLIT DUCTLESS SYSTEMS
Features of Heating Operations
Important: Heating operation will cease at
approximately 15° F outdoor temperature
due to a sensor located in the outdoor unit.
This product does not contain supplemen-
tal electric heat, therefore other means of
heat need to used when this system ceas-
es operation at low outdoor ambients.
Basic principles and performances
• The Heat Pumps absorb heat from the
outdoor air and transfers it indoors to
heat the indoor air. The heating capa-
bilities through this principle go up/down
with the increase/decrease of the tem-
perature of the outdoor air.
• When the outdoor air temperature is very
low, the system can be used together
with other heating devices. Good ven-
tilation should be maintained to ensure
safety and prevent accidents.
Maintenance
The air conditioner must be turned off before the maintenance is to be carried out.
Before the operating season
1) Check if there are any materials block-
ing the intake and outlet vents of the
indoor and outdoor units.
2) Check if the installation stand is cor-
roded or rusty.
3) Check if the unit is properly grounded.
4) Check if the air filter is clean.
5) Connect to the power source.
6) Put batteries in the remote controller.
During the operating season
Check the air filter periodically during the
season and clean it if it is dirty.
Note: Do not open the grille to an angle over 60 degrees.

Defrosting
When the outdoor air temperature is very
low and humidity is very high, frosting will
occur in the heat exchanger of the outdoor
unit, which has negative impacts upon the
efficiency of the heating performance. In
this case, the automatic defrosting function
will come into play. The heating operation
will be stopped for 5-10 minutes to do the
defrosting.
• The fans of both the outdoor and indoor
units are stopped. During the defrosting
operation, the run light will flash slowly.
•
During defrosting, the outdoor unit might
generate some steam. It is caused by
fast defrosting, which is not a perfor-
mance failure.
• Upon the completion of the defrosting pro-
cess, the heating operation is resumed.
1) To remove the air filter screen from the unit.
• Gently press the two lower ends of
the grille and open it.
• Carefully lift the air filter screen up
and out pulling it toward you.
2) To Clean the air filter screen vacuum
it with a brush attachment (do not lift
the front cover more than 60°). If the
screen is very dirty, use lukewarm wa-
ter (about 86°F or 30°C) to wash it. Air
dry after washing.
• Do not use boiling water to clean the
screen.
• Do not use exess heat or an open
fire to dry the screen.
• Do not exert too much force pulling
or stretching the screen.
3) Replace the air filter screen.
Do not operate the air conditioner
without the air filter screen. To do
so will cause dirt to collect on the inte-
rior of the unit which may lead to poor
performance and damage the unit.
