BEST PRACTICES
Unit Placement
Follow clearance guidelines on indoor &
outdoor units for proper airflow & servicing
Include space for drainage so condensate
flows out of unit
Anchor both units properly to prevent vibration
or malfunction
Be sure condensate drain tubing is pitched
downward for proper drainage
Wiring
Use only 14/4 STRANDED wire
Never use wire nuts or wire splices
L1 & L2 are polarity sensitive
Use non-insulated spade connectors on
all terminal connections
Use only a dedicated electrical circuit
Always GROUND indoor & outdoor unit
Surge protector HIGHLY recommended
I.E. Intermatic AG3000
Piping
Use only correct line set size as determined
by indoor unit
Use only copper refrigerant piping
Insulate both refrigerant lines from each other
For flare connections, use a 45° flaring tool
such as Yellow Jacket Deluxe
Use a pipe length that does not exceed the
maximum or go below the minimum length
Do not make vertical loops in the piping
support runs from sagging or bending
Charging
Test refrigerant lines for leaks by
pressurizing with nitrogen to 500 P.S.I.
While under pressure, use a leak detection
solution to test for all leaks at all flare
connections
Use only approved evacuation hose & vacuum
pump oil for proper evacuation and leak
testing: Evacuate to less than 500 microns
and hold for 30 minutes
If refrigerant is added, use electronic scale
and weigh in precise amount
Open service valves prior to energizing unit
