FLASH: PHASE PROBLEM
1. Compressor damage may occur if system is over
charged.
2. This unit is factory charged with R-22 in accordance
with the amount shown on the rating plate. The
charge is adequate for most systems using
matched coils and tubing not over 15 feet long.
The best performance will be achieved when the
unit operates with a suction gas superheat at the
compressor inlet of 5 ºF at normal rating conditions
of the air conditioning and refrigeration, institute
(ARI). This chart may be used to approximate the
charge if ARI rating conditions cannot be obtained.
ARI rating conditions are equivalent to DOE test "A"
conditions. See product data literature for required
indoor air flow rates and for use of line lengths over
15 Ft.
3. Relieve pressure and recover all refrigerant before
system repair or final unit disposal. Use all service
ports and open all flow-control devices, including
solenoid valves.
1. Compressor and fan motor furnished with
inherent thermal protection.
2. To be wired in accordance with National
Electric Code (N.E.C.) and local codes.
3. N.E.C. class 2, 24V circuit, min. 40 VA required.
4. Use copper conductors only, from disconnect
to unit.
5. Must use thermostat and sub-base as stated
in pre-sale literature.
6. If indoor section has a transformer with a
grounded secondary, connect the grounded
side to "C" on the circuit board.
7. If any of the original wire, as supplied, must
be replaced, use the same or equivalent wire.
8. Check all electrical connections inside control
box for tightness.
9. Do not attempt to operate unit until service
valves have been opened.
10. It is imperative to connect 3Ø field power
to unit with correct phasing. The Phase
Rotation Monitor will not allow the contactor
to be energized if thephasing is not correct.
If phasing is reversed, simply interchange any two
of the three power connections on the field side.
11. Use conductors suitable for at least 75ºC (167ºF).

1. Operate unit a minimum of
10 minutes before checking
charge.
2. Measure suction pressure
by attaching a gage to
suction valve service port.
3. Measure suction temperature
by attaching an accurate
thermistor type or electronic
thermometer to the suction
line at service valve.
4. Measure outdoor air dry-bulb
temperature with a
thermometer.
5. Measure indoor air (entering
indoor coil) wet bulb
temperature with a sling
psychrometer.
6. Refer to table I. Find out-
door temperature and
evaporator entering air wet-
bulb temperature at this
intersection note the super-
heat.
7. Refer to table II. Find super-
heat temperature located in
step 6 and suction pressure,
at this intersection note
suction line temperature.
8. If unit has a higher suction
line temperature than charted
temperature, add refrigerant
until charted temperature
is reached.
9. If unit has a lower suction
line temperature than charted
temperature, remove and
recover refrigerant until
charted temperature is
reached.
10. If outdoor air temperature
or pressure at suction valve
changes, charge to new
suction line temperature
indicated on chart.
11. This procedure is valid when
indoor air flow is within
+/- 21% of its rated cfm.
