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.
REAR:
Min 18” (457 mm)
requried for service
Note: Observe requirements for 39” (914 mm) operating clearance
on either Left or Rear coil opening.
RIGHT:
Min 18” (457 mm)
requried for service
LEFT:
Min 18” (457 mm)
requried for service
FRONT:
42” (1067 mm)
requried for service
C110201
Fig. 4 -- Service Clearance Dimensional Drawing
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.
Evaluate the path and required line length for
interconnecting refrigeration piping, including suction
riser requirements (outdoor unit above indoor unit), liquid
line lift (outdoor unit below indoor unit) and hot gas
bypass line. Relocate sections to minimize the length of
interconnecting tubing.
DO NOT BURY REFRIGERATION LINES.
Although unit is weatherproof, avoid locations that permit
water from higher level runoff and overhangs to fall onto
the unit.
Step 2 — Complete Pre-Installation Checks
Check Unit Electrical Characteristics:
Confirm before
installation of unit that voltage, amperage and circuit
protection requirements listed on unit data plate agree with
power supply provided.
Un--crate Unit
: Remove unit packaging except for the top
skid assembly, which should be left in place until after the
unit is rigged into its final location.
Inspect Shipment:
File a claim with shipping company if
the shipment is damaged or incomplete.
Consider System Requirements:
S
Consult local building codes and National Electrical Code
(NEC, U.S.A.) for special installation requirements.
S
Allow sufficient space for airflow clearance, wiring,
refrigerant piping, and servicing unit. See Fig. 3 for unit
dimensions and weight distribution data.
S
Locate the unit so that the outdoor coil (condenser)
airflow is unrestricted on all sides and above.
S
The unit may be mounted on a level pad directly on the
base channels or mounted on raised pads at support
points. See Tables 1A through 2B for unit operating
weights. See Fig. 3 for weight distribution based on
recommended support points.
