• Couper toute alimentation électrique au générateur
d’air chaud avant de procéder aux travaux
d’entretien.
• Au moment de l’entretien des commandes,
étiqueter tous les fils avant de les débrancher.
S’assurer de les raccorder correctement.
• S’assurer que l’appareil fonctionne adéquatement
après l’entretien.
Proper maintenance is important to achieve optimum
performance from the air conditioner. The ability to properly
perform maintenance on this equipment requires certain
mechanical skills and tools. If you do not possess these
skills, contact your dealer for maintenance. Consult your
local dealer about the availability of maintenance contracts.
Routine maintenance should include the following:
• Inspect the condensate drain and outdoor coil at the
beginning of each cooling season. Remove any debris.
Clean the outdoor coil and louvers as necessary using a
mild detergent and water. Rinse thoroughly with water.
• Inspect the electrical connections for tightness at the
beginning of each heating and cooling season. Service
as necessary.
• Inspect and clean or replace air filters at the beginning
of each heating and cooling season, or more frequently
if required.
caution:
the unit should never be operated without a
filter in the return air system. replace disposable
filters with the same type and size.
• The motors for the circulating air blower and the outdoor
fan are pre-lubricated at the factory. No further oiling is
required for the life of this product.
reFrigerant cHarging
Warning:
Single Packaged air conditioners are shipped
fully charged with r-410a refrigerant and ready
for installation. When a system is installed
according to these instructions, no refrigerant
charging is required. if repairs make it necessary
for evacuation and charging, it should only be
done by qualified, trained personnel thoroughly
familiar with this equipment. Some local codes
require licensed installation/service personnel
to service this type of equipment. under no
circumstances should the owner attempt to
install and/or service this equipment. Failure to
comply with this warning could result in property
damage, personal injury, or death.
The system refrigerant charge can be checked and
adjusted through the service ports provided at the front
panel. Use only gauge lines which have a Schrader
depression device present to actuate the valve. After
refrigerant line connections are completed, leak check
and evacuate the indoor section and all line connections
(using proper methods) before finalizing the full system
refrigerant charge.
• P8SE outdoor units with non-AHRI listed indoor coils
are not recommended. Deviations from rated airflows or
non-listed combinations may require modification to the
expansion device and refrigerant charging procedures
for proper and efficient system operation.
• The refrigerant charge can be checked and adjusted
through the service ports provided external to the outdoor
unit. Use only gage line sets which have a “Schrader”
depression device present to actuate the valve.
• A high-pressure switch is factory-installed and located
in the liquid line internal to the outdoor unit. The switch
is designed to protect the system when very high
pressures occur during abnormal conditions. Under
normal conditions, the switch is closed. If the liquid
pressure rises above 650 psig, then the switch will open
and de-energize the outdoor unit. The switch will close
again once the liquid pressure decreases to 460 psig.
Please note that the switch interrupts the thermostat
inputs to the unit. Thus, when the switch opens and
then closes, there may be a 5 minute short cycling delay
before the outdoor unit will energize.
