(With Outdoor Temperatures Above 65° F)
1. With the system operating at steady-state, measure the
liquid refrigerant pressure in psig at the service valve.
2. Measure the liquid refrigerant temperature in Fahrenheit
at the service valve.
3. For the temperature measured, determine the required
liquid refrigerant pressure from the appropriate charging
charts in
Figure
9,
Figure 10 (page
Figure 12 (page
17),
18).
4. If the pressure measured in step 1 is greater than the
required liquid refrigerant pressure determined in step
4, then there is too much charge in the system. Remove
refrigerant and repeat steps 1 through 3 until the system
is correctly charged.
5. If the pressure measured in step 1 is less than the
required liquid refrigerant pressure determined in
step 4, then there is too little charge in the system.
Add refrigerant and repeat steps 1 through 3 until the
system is correctly charged.
charging an R-410A Unit in Heating Mode
1. Evacuate the refrigerant system.
2. Weigh in the proper charge based on the charge level
noted on the rating plate. Unit charge MUST be verified
in cooling season.
3. Verify the unit is operating properly as outlined in System

HEAt PUMP MAIntEnAncE
to prevent electrical shock, personal injury, or
death, disconnect all electrical power to the unit
before performing any maintenance or service.
Unit may have more than one electrical supply.
11,
Use care when servicing the heat pump or
removing components. Personal injury can
result from sharp edges present in equipment
constructed with sheet metal
Proper maintenance is important to achieve optimum
performance from the heat pump. 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 and clean or replace air filters at the beginning
of each heating and cooling season, or more frequently
if required.
• 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.
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.
