(NOTE #5)
NOTES:
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,
60 VA on units installed with LLS.
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. Use conductors suitable for at least 75ºC (167ºF).
CAUTION
1. Compressor damage may occur if system is
over charged.
2. This unit is factory charged with R-410A 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. Check refrigerant charge for maximum
efficiency. See Product Data Literature for
required Indoor air Flow Rates and for use of
line lengths over 15 feet.
3. Relieve pressure and recover all refrigerant
before system repair or final disposal. Use all
service ports and open all flow-control devices,
including solenoid valves.
4. Never vent refrigerant to atmosphere.
Use approved recovery equipment.

CHARGING PROCEDURE
1. Operate unit a minimum of 10 minutes
before checking charge.
2. Measure suction pressure by attaching
an accurate 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 outdoor
temperature and evaporator entering
5 7 10
air wet-bulb temperature. At this
3 6 8 intersection, note superheat. Where a
dash (- -) appears on table do not
attempt to charge system under these
conditions or refrigerant slugging may
occur. Charge must be weighed in,
adding or removing 0.6 oz/ft of 3/8
liquid line above or below 15 ft.
respectively.
7. Refer to Table II. Find superheat
temperature located in step 6 and
suction pressure. At this intersection
note suction line temperature.
8. If unit has a higher suction line
49 51
temperature than charted temperature,
53
51
add refrigerant until charted
53 55
temperature is reached.
57
55
9. If unit has a lower suction line
57 59 temperature than charted temperature,
remove and recover refrigerant until
59 61
charted temperature is reached.
63
61
10. When adding refrigerant, charge in
63 65
liquid form into the suction service port
67
65
using a flow-restricting device.
67 69
11. If outdoor air temperature or pressure
69 71
at suction valve changes, charge to
73
71
new suction line temperature indicated
73 75
on chart.
75 77
12. This procedure is valid when indoor air
flow is within +/- 21% of its rated cfm
