4. BEFORE CONTACTING YOUR DEALER

Since the system has protection controls, you may en-
counter the following:

Although the room temperature is lower than the set point,
hot air doesn’t flow into the room when the unit is in heat
mode.

1. The gas furnace doesn’t light when the heat pump is

under a particular operation such as: the start up of the
compressor, the shut off of the compressor, before de-
frost or after defrost.

In those cases, the gas furnace will light automatically
after finishing the particular operation of the heat pump.
This may take from two minutes to more than ten min-
utes.

The heat pump doesn’t switch over to the gas furnace even
though the room temperature is much lower than set point.

Or, the gas furnace doesn’t switch over to the heat pump
even though the room temperature is almost at set point.

1. The heat pump and gas furnace will not switch over each

other according to room temperature automatically if  the
outdoor unit is not configured to automatically switch
heat sources.  But, the system may be able to automati-
cally switch between of heat pump and gas furnace op-
eration according to outside ambient temperature. In that
case, the compressor will stop when the gas furnace
will operate.

2. The field setting of the switch over temperature might

not be exact.  This setting can be confirmed and changed
by only your Daikin dealer.

3. In order to protect the system, a prohibition timer is used

to prevent frequent switch over between heat pump and
gas furnace.  Once the gas furnace lights, the system
will not switch over until the pre-determined prohibition
time has passed.  This setting can be confirmed and
changed by your Daikin dealer.

The gas furnace doesn’t stop combustion heat even when
the room temperature has been satisfied.

1. The gas furnace may not stop during the defrost pro-

cess of the heat pump to prevent blowing cool air flow.
After the defrost operation, the gas furnace will stop.
Turning the remote controller off can shut off the gas
furnace.  If you don’t need combustion heating during
defrost operation, it will be achieved by field setting.  Ask
your Daikin dealer for setting change.

 MAINTENANCE

Only a licensed professional contractor should per-
form routine maintenance and service.

Only a licensed professional contractor is allowed
to install optional parts.

Be sure to use the optional parts specified by the manu-
facturer.  Installation of unauthorized parts may result
in water leakage, electric shock or fire.

Do not use flammable material (e.g. hair-spray or in-
secticide) near the product.

Do not allow the indoor unit to get wet as it may
cause an electric shock or fire.

Clean the unit only after turning it off and disconnecting
the power supply.

Failure to do so may result in electric shocks or injury.

________________________________________________

Use a stable prep stand.

Pay extra attention when cleaning the cased coil.

(Maintenance and inspection)

Clean the drain pan periodically. If dust clogs the drain-
age pipes, water leaks will occur.

For cleaning, contact your Daikin dealer. (Coils should
be cleaned before cooling or heating seasons begin.)

If the area around the indoor unit is very dusty, use a
dust proof cover (local procurement).

(Cleaning the inside of the indoor unit)

It is necessary to clean the inside of the indoor unit pe-
riodically.

Cleaning the indoor unit requires a trained professional.
Contact your Daikin professional to clean them.

Wrong cleaning procedures may damage the heat ex-
changer surfaces, break plastic parts, cause water leak-
age, or cause electric shock.

(Cleaning the air filter)

The air filter is an optional accessory for the connected
gas furnace.

EXPLANATION:

Removing the air filter

,

 except when cleaning the cased

coil

,

 may result in accidents.
