Matching 569J Model to Evaporator Coil
The Model 569J***A/B/G/H is a single-circuit unit design,
requiring one set of refrigeration piping. This model can be
connected to an evaporator coil with one circuit or with two
circuits (by manifolding the evaporator connections into a
single piping system).
The Model 569J***D/E/F is a dual-circuit unit design that
requires two sets of refrigeration piping between the
outdoor unit and the evaporator coil (or coils). This model
can only be connected to an evaporator coil that has two
refrigeration circuits (or to two separate evaporator coils).
The Model 569J***D/E/F CANNOT be connected to a
single-circuit evaporator coil. The Model 569J***D/E/F
CANNOT be field-converted to a single-circuit design.

INSTALLATION
.
Jobsite Survey
Complete the following checks before installation.
1. Consult local building codes and the NEC (National
Electrical Code) ANSI/NFPA 70 for special installa-
tion requirements.
2. Determine unit location (from project plans) or select
unit location.
3. Check for possible overhead obstructions which may
interfere with unit lifting or rigging.
Step 1 — Plan for Unit Location
The 569J units are designed and approved for outdoor
installation only. Do not locate these units indoors. Do not
add ducting to unit fan system.
Select a location for the unit and its support system (pad,
rails or other) that provides for the minimum clearances
required for safety. This includes the clearance to
combustible surfaces, unit performance and service access
below, around and above unit as specified in unit drawings.
See Fig. 4.
NOTE:
Local codes may require different clearances
than specified in Fig. 4. It is the responsibility of installers
to be knowledgeable in local codes and to modify the
recommended clearances to satisfy local codes.
NOTE:
Consider also the effect of adjacent units on
airflow performance and control box safety clearance.

Do not install the outdoor unit in an area where fresh air
supply to the outdoor coil may be restricted or when
recirculation from the condenser fan discharge is possible.
Do not locate the unit in a well or next to high walls.
