GENERAL

This instruction cov ers the insta llation of the f ollowing o ut door
units: E1FD018A(S)06, E9FD018S06, E1FD024A(S)06,
E9FD024S06, E1FD030A(S)06, E9FD030S06,
E1FD036A(S)06, E9FD036S06, E1FD036S(25,46),
E1FD042A(S)06, E1FD048A(S)06 E1FD048S(25, 46),
E1FD060A(S)06, E1FD060S0 6(2 5, 46).

The outdoor units are designed to be c onnected t o a matchin g
indoor coil with either quick or sweat connect lines. Quick
connect units a re fac to ry char ged w ith ref rig era nt for a m atch­ing indoor coil and factory charged line sets are available in
various lengths . Sweat connect unit s are fa ctory char ged wit h
refrigerant for a matching indoor coil plus 15 feet of field
supplied lines.

Matching indoor coils are available with a thermal expansion
valve or an orifice liquid feed (YORKMA TE f low control device)
sized for the most common usage. The orifice size and/or
refrigerant charge may need to be changed for some indoor­outdoor unit combinations, elevation differences or total line
lengths. Refer to Application Data covering “General Piping
Recommendations and Refrigerant Line Length” (Form

690.01-AD1V).
THIS UNIT IS NOT EQUIPPED WITH A FILTER DRIER. A

SOLID CORE BI-FLOW DIRECTIONAL FILTER IS RE­QUIRED FOR INS T ALLATIO N AND ANY TIME T HE REFRIG­ERANT CIRCUIT IS OPENED.

INSPECTION

As soon as a unit is rece ived, it sho uld be inspected for possible
damage during transit. If damage is evident, the extent of the
damage should be noted on the carrier’s delivery receipt. A
separate request for inspection by the carrier’s agent should
be made in writing. See Local D istributor for more info rmation.

REFERENCE

Use this instruction in conjunction with the instructions for the
appropriat e indoor unit, air moving sys te m and acce ssor ies.

LOCATION

Before starting the inst allat ion, select and check the su itab ility
of the location for both the indoor and outdoor unit. Observe all
limitations and cleara nce r equir em ent s, see Figu re 3.

5. Install liquid line filter drier. See “DRIER INSTALLA TI O N”

6. Connect tubing and leak test.

7. Make electrical control connect ions.

DRIER INSTALLATION

The outdoor un it must have suff icient clearance for a ir entrance
to the condenser coil, for air disch arge and for service access.

If the unit is to be installed on a hot sun exposed roof or a
black-topped g round area , the unit should be raised sufficient ly
above the roof or ground to avoid taking the accum ulated layer
of hot air into the outdoor unit.

Provide an adequate structur al supp ort.
The unit may be installed at ground level on a solid base that

will not shift or settle, caus ing strain on the r efrigeran t lines and
possible leaks. Maintain the clearances shown Figure 3 and
install the unit in a level position. Isolate the base from the
building structure to avoid noise or vibratio n transmiss io n.

When instal ling units on a roof, the stru ct ure must be capa bl e
of supporting the total we ight of the unit, including a pad, lintels,
rails, etc., which should be used to minimize the transmission
of sound or vibration into the cond itione d space.

Isolate the unit from rain gut ters to av oid any possible wa sh out
of the foundation.

Normal operat ing sound levels may be objec tionable if the unit
is placed directly under windows of cert ain room s (bedr oom s,
stud y, etc. ).

Condensate will drain from beneath t he coil of the outdoor unit
during the defrost cycle. Normally this condensate may be
allowed to drain directly onto the ground. A gravel bed ma y be
used to prevent mud splash ing.

NOTE: DRIERS ARE NOT SUPPLIED WITH THIS EQUIP-

MENT AND MUST BE FIELD INSTALLED AT THE
TIME OF EQUIPMENT INSTALLAT ION.

For new installations we recommend a 8 cubic inch minimum
solid core bi-flow filter-drier for 1- 3 tons, and a 10 cubic inch
minimum for 3.5 - 5 tons. Install in the liquid line, external to
the outdo or un it.

For clean-up after a burnout a larger capacity drier is recom­mended. Always remove any driers on the unit at the time of
burnout. Driers should be replaced any time the refrigerant
circuit is re paired. When adding a drier to a system, additional
refrigerant mu st be added to comp ensate for the drier addition.
Refer to vendor specifications for the additional refrigerant
amount.

For a particular filter-drier brand, refer to Source 1 Manual or
original manuf actor’s recommended size, additional re frigerant
charge requirem ent s, con nect ion size and type.

WARNING:The outdoor unit should not be installed in an area

where mud or ice could cause personal injury.
Remember that condensate will drip from the unit
coils during heat and defrost cycles and that this
condensate will fre eze when the t emperature of the

°

outdoor air is below 32

F.

Elevate the unit sufficiently to prevent any blockage of the air
entrances by s now in areas wher e there w ill be snow accum u­lation. Check the local weather bureau for the expected snow
accumulatio n in your area .

INSTALLATION PROCEDURES

The following sequence of instal lation steps is suggested.

1. Inspect unit and set in pla ce.

2. Make electrical power connections.

3. C heck orifice si ze and replace with correct size if necessary.

4. Route the vapor and liquid line s.

ELECTRICAL CONNECTIONS

1. Check the electrical supply to be sure that it meets the
values specified on the unit na meplat e and wiring label.

2. Remove proper low voltage knockout. Remove plast ic snap
bushing from instruction packet and insert in low voltage
knockout hole.

3. The com plete connection diagram and schematic wiring label
is located on the inside surface of the unit electrical box cover .
Typical Field W iring is shown in Figures 4 and 5.

4. All field wiring to be in accordance with national electrical
code (NEC) and/or local city codes.

A warning label with an adhesive back is supplied in the unit
installation inst ruction packe t. This label should be att ached to
the field supplied disconne ct switch where it will be easily seen.
See below:

NOTE: Power wiring, discon nect switch, and o ver curren t pro-

tection to be supplied by installer. See Physical and
Electrical Data Table for proper sizes. USE COPPER
CONDUCTORS ONLY. Unit must be grounded with a
separate ground conductor wire.

5. Install the proper size weather proof disconnect switch out­doors and within sight of the unit.

6. Run power wiring from the disconnect switch to the unit.

7. Install the proper size time-delay fuses or circuit breaker,
and make the power supply connect ions.

8. Energize the crankcase heater, if applicable, to save time
by preheating the compressor oil while the remaining insta l­lation is complet ed.
