Howeowners's Routine Maintenance - Daikin GPHM5 SEER2 M Series Installation Instructions Manual

We strongly recommend a bi-annual maintenance checkup be performed by a qualified service agency before the heating and cooling seasons begin.
HIGH VOLTAGE!
Disconnect all power before servicing or
installing this unit. Multiple power sources
may be present. Failure to do so may cause
property damage, personal injury or death.
Replace or Clean Filter
IMPORTANT NOTE: Never operate unit without a
filter installed as dust and lint will build up on
internal parts resulting in loss of efficiency,
equipment damage and possible fire.
A return air filter is not supplied with this unit;
however, there must be a means of filtering the
return air. An indoor air filter must be used with
your comfort system. A properly maintained filter
will keep the indoor coil of your comfort system
clean. A dirty coil could cause poor operation
and/or severe equipment damage.
The installer of your unit can tell you where your filter(s)
are and how to clean or replace them.
Check your return filter(s) at least once every two months.
When they are dirty, replace or clean as required.
Disposable type filters should be replaced. Reusable type
filters may be cleaned.
NOTE: Reusable type filters should be washed
with warm water, dried completely and sprayed
with an adhesive according to the manufacturers
recommendations.
You may want to ask your dealer about high efficiency
filters. High efficiency filters are available in both electronic
and non-electronic types. These filters can do a better job
of catching small airborne particles.
Improper filter maintenance is the most common cause of
inadequate heating or cooling performance. Filters should
be cleaned (permanent) or replaced (disposable) every two
months or as required. When replacing a filter, it must be
replaced with a filter of the same type and size and always
make certain the air flow arrows on the filter point in the
proper direction.
Condenser and Evaporator Motors
The bearings on the air circulating blower motor and
condenser motor are permanently lubricated and require
no further lubrication.
Compressor
The compressor motor is hermetically sealed and does not
require additional oiling.

HOMEOWNER'S Routine Maintenance Recommendations
WARNING
- HEAT PUMP AND AC UNITS
Aluminum Indoor Coil Cleaning
(Qualified Servicer Only)
This unit is equipped with an aluminum tube evaporator
coil. The safest way to clean the evaporator coil is to
simply flush the coil with water. This cleaning practice
remains as the recommended cleaning method for both
copper tube and aluminum tube residential cooling coils.
An alternate cleaning method is to use one of the products
listed in the technical publication TP-109 (shipped in the
literature bag with the unit) to clean the coils. The cleaners
listed are the only agents deemed safe and approved
for use to clean round tube aluminum coils. TP-109 is
available on the web site in Partner Link > Service Toolkit.
NOTE: Ensure coils are rinsed well after use of
any chemical cleaners.
Annual Inspection (Qualified Servicer Only)
Your package unit should be inspected by a qualified
installer, or service agency at least twice every year.
This check should be performed before the heating and
cooling seasons begin. This will ensure that the system is
performing properly and safely. Repair as necessary.
• Check physical support of the unit. Ensure it is sound
without any sagging, cracks, or gaps, around the base.
• Check for obvious signs of deterioration of the unit.
• Check both condenser and evaporator coil to make
sure each are clean.
• Return Air Connection. Check for physical soundness
and ensure that the connection is firmly sealed to the
package unit casing.
• Wiring. Check wires for damage. Check electrical
connections for tightness and/or corrosion.
• Filters. Check that filters are clean and in the proper
placement in the unit or duct system.
• Louvers. Inspect air inlet louvers inside the heat
exchanger compartments. Ensure the area is clean
and free of dirt and debris.
Before Calling Your Servicer
• Check the thermostat to confirm that it is properly set.
• Check the disconnect switch near the unit to confirm
that it is closed.
• Check the electrical panel for tripped circuit breakers
or failed fuses. Reset the circuit breakers or replace
fuses as necessary.
• Check for blockage of the indoor air inlets and outlets.
Confirm that they are open and have not been
blocked by objects (rugs, curtains or furniture).
• Check for obstructions on the unit. Confirm that it has
not been covered on the sides or the top. Remove
any obstruction that can be safely removed. If the unit
is covered with dirt or debris, call a qualified servicer
to clean it.
• Check the filter. If it is dirty, clean or replace it.
