WARNING
ELECTRICAL SHOCK HAZARD
Failure to follow this warning could result in personal
injury or death.
Before installing, modifying, or servicing system, main
electrical disconnect switch must be in the OFF
position. There may be more than 1 disconnect
switch. Lock out and tag switch with a suitable
warning label.
NOTE: There may be more than one electrical disconnect
switch.
CUT HAZARD
Failure to follow this caution may result in personal
injury.
Although special care has been taken to minimize sharp
edges in the c onstruction of your unit, be extremely
careful and wear appropriate protective clothing and
gloves when handling parts or reaching into the unit.
CAUTION
!
S Do Not Block Floor, Wall or Ceiling Vents
When drapes, furniture, toys or other common household
items block vents, the restricted airflow lessens the system’s
efficiency and life span.
S Do Not Cover or Block Outdoor Unit
The outdoor unit needs unrestricted airflow. Do not cover it or
place items on or next to it. Do not allow grass clippings,
leaves, or other debris to accumulate on the sides or top of
the unit. And, maintain a 12” (304.8 mm) minimum clearance
between the outdoor unit and tall grass, vines, shrubs, etc.
S Check Condensate Drain
Your heat pump removes humidity from your home during the
cooling season. After a few minutes of operation, water
should trickle from the condensate drain of the indoor coil.
Check this occasionally to be sure the drain system is not
clogged. Drainage will be limited if you live in a very dry
environment.
S Do Not Operate Below Minimum Operating
Temperatures in Cooling Mode
Your outdoor unit is not designed to operate below the
minimum temperatures shown below. The minimum
temperature depends on which wall control is being used:
— With Observer
®
Wall Control: 40_F(4.4_C)
— With Thermostat Control: 55_F (12.8_C)
System protections may not allow the unit to operate below
these minimum temperatures.
S Do Not Operate Above 66°F/18.89_CinHeatingMode
Your outdoor unit is not designed to operate on heating mode
when outdoor temperatures are higher than 66°F (18.9_C).
You can safely operate the system above 66°F (18.9_C) on
emergency or auxiliary heat.
S Minimum Heating Temperature
This unit is not designed to operate at extreme cold outdoor
temperatures. When the outdoor temperature is below 10_F
(- 12.2_C) the unit c ontrol may automatically shut the heat
pump off and energize auxiliary heat to maintain the desired
temperature set point inside the home.
S Base Pan Drainage
Periodically check for and remove debris that has settled
around the base of your outdoor unit. This will ensure proper
drainage of the base pan and eliminate standing water inside
the outdoor unit.
S Level Installation
Your dealer will install the outdoor unit in a level position. If
the support base settles or shifts and the unit is no longer
level, be sure to re- level it promptly to assure proper
drainage. If you notice water or ice collecting beneath the unit,
arrange for it to be drained away from the unit.
SEA COAST COIL MAINTENANCE
Coastal locations often require additional maintenance of the
outdoor unit due to highly corrosive airborne ocean salt.
Although your new system is made of galvanized metal and is
protected by top - grade paint, take the additional precaution of
periodically washing all exposed surfaces and the outdoor coil
approximately every 3 months. Consult your installing dealer
for proper cleaning intervals and procedures for your
geographic area or ask about a service contract for regularly
scheduled professional cleaning and inspections.
TROUBLESHOOTING
Before you request dealer service, check for these easily
solved problems:
S Check the indoor and outdoor disconnect switches Also
check your main electrical panel circuit breakers or fuses.
S Turn circuit breaker off for at least 2 minutes, and turn
back on to re- start the system.
S Check for sufficient airflow. Air filter(s) s hould be
reasonably clean and interior vents should be open and
unobstructed.
S Check Observer Wall Control or thermostat settings. For
cooling, your desired temperature setting should be
LOWER than the displayed room temperature, and the
System/Mode control should be on Cool or Auto. For
heating, your temperature setting should be HIGHER than
the displayed room temperature, and the System/Mode
control is set to Heat or Auto.
S Time delays - depending on the heat pump you have,
there may be delays in unit operation that are built- in to
protect the equipment and your comfort. Don’t be alarmed
if you notice a time delay in operation. It may be a
standard protection feature of your equipment. Check
with your Dealer for more information on time delays.
If you need to contact your dealer for troubleshooting and/or
repairs, be sure to have the model and serial numbers of your
equipment available (there are spaces on the cover for you to
write this information).
REGULAR DEALER MAINTENANCE
In addition to the routine maintenance that you perform, your
home comfort system should be inspected regularly by a
properly trained service technician. Many dealers offer this
service at a reduced rate with a service contract. Some
service contracts offer additional benefits such as parts
discounts and no additional charge for ”after hours” or
emergency service.
Your annual system inspection should include:
S Routine inspection of air filter(s) with replacement or
cleaning as required
S Inspection and cleaning of the blower wheel housing and
motor
S Inspection and, if required, cleaning of indoor and outdoor
coils
S Inspection of the indoor coil drain pan, as well as the
primary and secondary drain lines. If the system has an
auxiliary drain pan and line, they should be inspected at
this time as well. Service should include cleaning if
required.
S Check all electrical wiring and connections
S Check for secure physical connections of individual parts
in each unit
S Operational check of the heat pump system to determine
actual working condition. Necessary repair and/or
adjustment should be performed at this time.
