GENERAL

This instructi on co ve rs the ins tallation of the fol lowing o ut door
units: E1FB012A(S)06, E1FB018A(S)06, E1FB024A(S)06,
E1FB030A(S)06, E9FB012S06, E9FB018S06, E9FB024S06,
and E9FB030S06.

The outdoor unit s are desig ned to be connec ted to a matching
indoor coil with either quick or sweat connect lines. Quick
connect units are factory charged with refrigerant for a match­ing indoor coil and factory charged line sets are available in
various lengths. Sweat connect units are factory charge d wi th
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 flow control devi ce)
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 Le ngt h”.

LIMITATIONS

The unit should be installed in accordance wit h all national and
local safety co d es.

Limitations for the ind oor unit, coil and appropriat e accessories
must also be observ ed.

The outdoor unit mu st not be installed wit h any ductwork in the
air stream. The outdoor fan is the propeller type and is not
designed to opera te against any addit ional external sta tic pres­sure.

The maximum and minimum conditions for operation must be
observed to assure a syst em th at will give maximum per fo r m­ance with minimum service.

As soon as a un it is received, it should be ins pected for pos sible
damage during transit. If damage is evident, the extent of the
damage should be not ed on the carrier’s freight bill. A separate
request for inspec tion by the carrier’s agent should be made in
writing. See Form 50.15-NM for more information.

Before start in g th e ins ta llat ion , selec t and check the suitability
of the location for b oth the indo or and outdoor unit . Observ e all
limitations and clearan ce req uiremen ts, see Figure 2.

Normal operating sound levels may be objectionable if the unit
is placed directly under windows of certain rooms (bedrooms,
study, etc.).

The outdoor unit must have sufficient clear ance for air entrance
to the condens er coil, for air dis charge a nd for s ervice access .

If the unit is to be installed on a hot sun exposed roof or a
black-topped grou nd area, the unit shoul d be raised suf ficiently
above the roof or ground to avoid taking the accumulated lay er
of hot air in to the outdoor unit .

Provide an adequat e s truc tu ral su ppor t.
The unit may be installed at ground level on a solid base that

will not shift or settle, causing strain on the refriger ant lines and
possible leaks. Maintain the clearances shown Figure 2 and
install the unit in a level position. Isolate the base from the
building struct ure t o avoid no ise or vib rat ion t ran smis sio n.

When installing units on a roof, the structure must be capable
of support ing the tot al weight of the unit, inclu ding a pad, lintels ,
rails, etc., which should be used to minimize the transmission
of sound or vibration int o t he conditioned space.

Isolate the uni t from rain gutters to avoid any possible was h out
of the foundation.

Condensate will drain from ben eath the coil of the outdoor uni t
during the defrost cycle. Normally this condensate may be
allowed to drain directly onto the ground. A gra vel bed may be
used to prevent mud splas hi ng.

WARNING:The outdoor unit shou ld not be insta lled i n 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
condensat e will freeze when the temperature of the

°

outdoor air is below 32

F.

Elevate the unit sufficiently to prevent any blockage of the air
entrances by snow in areas whe re the re will be snow accumu­lation. Check the local weather bureau for the expected snow
accumulation in your area.

INSTALLATION PROCEDURES

The following sequence of install at ion ste ps is sugge sted.

1. Inspect unit and set in place.

2. Make electrical power connections .

3. Check orifice size and replace with correct size if neces­sary.
