INSTALLATION GUIDELINE
Replacement/Retrofit — R--22 to Puron
Replacement/retrofit installations require change-out of outdoor unit, metering device, and filter driers. Change-out of indoor coil (evaporator) and interconnecting tubing is recommended.
Existing evaporator coil – If the existing evaporator coil may be re-used, check with the coil manufacturer to verify the coil construction is suitable for operation with the higher pressures of Puron the existing TXV valve is compatible with R-410A, replace if necessary. The minimum factory test pressure rating must be 250 psig (1725 kPa). Existing coil will need to be purged with Nitrogen to remove as much mineral oil as possible to eliminate cross contamination of oils.
Acid test – If the existing system is being replaced because of a compressor electrical failure, assume acid is in system. If system is being replaced for any other reason, use an approved acid test kit to determine acid level. If even low levels of acid are detected, install a 100 percent activated alumina suction-line filter drier in addition to the replacement liquid-line filter drier. Remove the suction line filter drier as soon as possible, with a maximum of 72 hr of operation. Recommendation: Install a ball valve in the liquid line at the filter drier location when installing a suction filter in the suction line.
Existing refrigeration piping – Reuse of existing refrigerant piping involves three issues: quality (strength) of existing tubing, cleanliness and tube size. Inspect all tube segments and joints for signs of damage, corrosion or poor brazing. Flush the interconnecting piping system with dry Nitrogen to eliminate as much trace of mineral oil as possible.

tons with Puron than with R--22 (at 2_F pressure drop). Refrigeration lines selected for R--22 use are typically oversized for Puron applications. Carefully check the existing suction line size against the table for maximum size (see Table 8); replace vertical riser segments if necessary. Check existing liquid line size against sizing data in Table 5 or 6; replace with smaller lines when feasible.
Installation –
1. Remove the existing evaporator coil or fan coil and install the replacement coil when appropriate.
2. Drain oil from low points and traps in suction line tubing (and hot gas bypass tubing if appropriate) and evaporator if they were not replaced. Removing oil from evaporator coil may require purging of the tubing with dry nitrogen.
3. Unless indoor unit is equipped with a Puron approved metering device, change the metering device to a thermal expansion valve (TXV) designed for Puron
R
(R-410A).
4. Remove the existing outdoor unit. Install the new out­door unit according to these installation instructions.
5. Install a new field-supplied liquid-line filter drier at the indoor coil just upstream of the TXV or fix orifice metering device.
6. If a suction line filter drier is also to be installed, in­stall suction line drier downstream of suction line ser­vice valve at condensing unit.
!
CAUTION
7. If required, install a 100% activated alumina suction line filter drier at the outdoor unit.
8. Evacuate and charge the system according to the in­structions in this installation manual.
9. Operate the system for 10 hr. Monitor the pressure drop across the suction line filter drier. If pressure drop exceeds 3 psig (21kPa), replace suction-line and liquid-line filter driers. Be sure to purge system with dry nitrogen and evacuate when replacing filter driers. Continue to monitor the pressure drop across suction-line filter drier. Repeat filter changes if neces­sary. Never leave suction-line filter drier in system longer than 72 hr (actual time).

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.

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.
.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 installa­tion 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.
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.
10
NOTE: If vibration isolators are required for a particular installation, use the data in Fig. 3 to make the proper selection.
Step 3 — Prepare Unit Mounting Support
Slab Mount —
Provide a level concrete slab that extends a minimum of 6 in. (150 mm) beyond unit cabinet. Install a gravel apron in front of condenser coil air inlet to prevent grass and foliage from obstructing airflow.
Step 4 — Rig and Mount the Unit

UNIT DAMAGE HAZARD
Failure to follow this caution may result in equipment damage.
All panels must be in place when rigging. Unit is not designed for handling by fork truck.
Rigging: These units are designed for overhead rigging. Refer to the rigging label for preferred rigging method. Spreader bars are not required if top crating is left on the unit. All panels must be in place when rigging. As further protection for coil faces, plywood sheets may be placed against the sides of the unit, behind cables. Run cables to a central suspension point so that the angle from the horizontal is not less than 45 degrees. Raise and set the unit down carefully.
If it is necessary to roll the unit into position, mount the unit on longitudinal rails, using a minimum of 3 rollers. Apply force to the rails, not the unit. If the unit is to be skidded into position, place it on a large pad and drag it by the pad. Do not apply any force to the unit.
Raise from above to lift the unit from the rails or pad when unit is in its final position.
After the unit is in position, remove all shipping materials and top crating.
Step 5 — Determine Refrigerant Line Sizes
Select the recommended line sizes for 569J***A/B/G/H and 569J***D/E/F unit from the appropriate tables.
Determine the linear length of interconnecting piping required between the outdoor unit and indoor unit (evaporator). Consider and identify also the arrangement of the tubing path (quantity and type of elbows in both lines), liquid line solenoid size, filter drier and any other refrigeration specialties located in the liquid line. Refer to the indoor unit installation instructions for additional details on refrigeration specialties devices.
Determine equivalent line length adjustments for path and components and add to linear line lengths. See Table 4, Equivalent Lengths for Common Fittings, for usual fitting types. Also identify adjustments for refrigeration specialties. Contact Bryant Applications Engineering for additional data and information on equivalent lengths.

Liquid Lift —
A liquid lift condition exists when the outdoor unit is located below the indoor (evaporator) unit and liquid flows vertically up in a portion of the liquid line. The vertical column of liquid reduces the available state point subcooling at the evaporator coil’s thermal expansion valve. This effect reduces the length of liquid lift (feet of elevation) that a liquid line size can accommodate. Longer linear tube lengths will also reduce the amount of liquid lift possible.
Check Tables 5 (569J***A/B/G/H), 6 (569J***D/E) and 7 (569J*12F) for maximum liquid lift capabilities for line sizes. Reselect the liquid line tube size if necessary. If maximum available tube size cannot provide the required lift distance on this installation, relocate the outdoor unit to reduce the equivalent line length or the lift requirement.

Suction Riser —
A suction riser condition exists when the outdoor unit is located above the indoor (evaporator) unit and suction vapor must flow vertically up to return to the compressor. Oil return is a concern when the suction tube size is too large to produce the minimum refrigerant velocity to ensure oil return at minimum load conditions.
569J***A/B/G/H and 569J***D/E (WITHOUT HGBP) Check Table 8 for maximum suction tube size for 569J units at minimum load conditions. Consider suction speed riser (reduced tube size for vertical segment only) or double suction riser arrangement if the planned suction tube size does not provide necessary minimum flowrates for this riser.

569J*12F UNIT WITH OPTIONAL HOT GAS BYPASS Special consideration for suction riser requirements must be considered when applying this factory--installed hot gas bypass. It is extremely important to consider the lowest possible refrigerant tons of refrigerant flow when hot gas bypass is functioning to assure proper oil return up suction risers.
Table 7 provides recommended tube sizes for model 569J*12F unit which includes the factory--installed hot gas bypass system on Circuit 1. The selections in this table are based on evaluations of system minimum load operating conditions for comfort cooling applications, with compressor saturated suction pressure to 28_F (--2.2_C) minimum.
Table 7 includes liquid line size selections based on use of RTPF coil option only.
Table 7 includes three different suction line size selections for Circuit 1 based on the elevation difference conditions between the 569J unit and the evaporator coil location.
Outdoor unit ABOVE evaporator coil: This installation will have at least one suction riser segment. If the vertical elevation difference is less than 20--ft (6.1 m) linear feet and requires only one or two segments, consider a speed riser selection for Circuit 1; use the line marked VAPOR RISER REQUIRED; NOT GREATER THAN 20 FT (6.1 M). See Fig. 5. Tube S is the horizontal line size; tube A is the reduced diameter riser size.

NO VAPOR RISER line. Circuit 2 suction line: Because there is no hot gas bypass
system in Circuit 2, no special riser selections are necessary. Select Circuit 2 suction line from bottom line for all 569J*12F installations.
Vertical Separation (outdoor unit above indoor unit) –
Vertical elevation difference of 200 ft (60 m) is permitted when the outdoor unit (569J***A/B/G/H or 569J***D/E/F) is located above the indoor unit.

Step 6 — Complete Refrigerant Piping Connections
IMPORTANT: Do not bury refrigerant piping
underground.
IMPORTANT: A refrigerant receiver is not provided with the unit. Do not install a receiver.
Provide Safety Relief —
If local codes dictate an additional safety relief device, purchase locally and install locally. Installation will require the recovery of the factory shipping charge before the factory tubing can be cut and the supplemental relief device is installed.
Model 568J***D/E/F has two separate refrigeration systems. If required, each circuit will require a field-supplied/installed supplemental relief device.
Check 569J Model with Evaporator Coil Connections —
569J
Confirm before installation of unit that the evaporator coil connections are consistent with this 569J model. See Table 3 on page 10.
Insulate Suction Lines —
Apply closed-cell tubular insulation to all suction lines between evaporator coil connection and 569J unit’s suction service valve.
569J***D/E/F Piping Connections —
The 569J***D/E/F’s two circuits are designated Circuit 1 and Circuit 2. Circuit 1 is controlled by the thermostat’s Y1 (or TC1) contact and will be the first circuit on and last circuit off. Circuit 2 is controlled by the thermostat’s Y2 (or TC2) contact and this circuit is always the “lag” circuit.
Plan the Circuit 1 and Circuit 2 tubing segments carefully, mark each segment and check constantly as piping systems are assembled to avoid piping errors.
569J***D/E/F unit cannot be field-piped as a single-circuit/tandem system.
Final Tubing Check. 569J***D/E/F —
Before completing the field piping connections to the 569J***D/E/F unit service valves, confirm that the suction line to the indoor coil’s first--on/last--off circuit (and its companion liquid line) are correctly identified as Circuit 1 use for the 569J***D/E/F unit. If a suction riser is required, it must be in Circuit 1.
Connecting 524J to 569J***D/E/F: The 524J fan coil in sizes 12, 14 and 16 is a face-split coil design that also has its circuits designated as 1 and 2. See Fig. 8. Note that the lower coil segment changes as the arrangement of the 524J changes. In a vertical arrangement, the 524J’s lower coil segment is segment 2; this segment should be connected to the 569J***D/E/F’s Circuit 1. In a horizontal arrangement, the 524J’s lower segment is now segment 1; this segment should be connected to the 569J***D/E/F’s Circuit 1.
Note that refrigerant suction piping should be insulated.

See Fig. 7 for location of Circuit 1 and Circuit 2 service valves and field piping connections. Circuit 1 is on the right-hand side of the service valve compartment; Circuit 2 is on the left.
When a single piece evaporator coil with two separate circuits is connected to a 569J***D/E/F, the lower coil circuit should be connected to the 569J***D/E/F’s Circuit 1 so that the evaporator’s lower coil segment is first-on/last-off (to avoid re-evaporation of condensate on dry lower coil segments).

Install Filter Drier(s) and Moisture Indicator(s) —
Every unit MUST have a filter drier in the liquid line. 569J***D/E/F models require two filter driers (one in each liquid line). Locate the filter drier(s) at the indoor unit, close to the evaporator coil’s thermal expansion valve (TXV) inlets.
569J units include one (569J***A/B/G/H) or two (569J***D/E/F) Puron-duty filter drier(s), shipped in cartons attached to the unit basepan. Remove the filter drier(s) and prepare to install in the liquid line(s) at the evaporator coil. Do not remove connection fitting plugs until ready to connect and braze the filter drier into the liquid line position.

Installation of liquid line moisture indicating sightglass in each circuit is recommended. Locate the sightglass(es) between the outlet of the filter drier and the TXV inlet.
Refer to Table 10 for recommendations on refrigeration specialties.
In some applications, depending on space and convenience requirements, it may be desirable to install 2 filter driers and sight glasses in a single circuit application. One filter drier and sight glass may be installed at A locations (see Fig. 9) or 2 filter driers and sight glasses may be installed at B locations (see Figs. 9 and 10).
Select the filter drier for maximum unit capacity and minimum pressure drop. Complete the refrigerant piping from the indoor unit to the outdoor unit before opening the liquid and suction lines at the outdoor unit.
Install Liquid Line Solenoid Valve —
It is recommended that a solenoid valve be placed in the main liquid line (see Figs. 9 and 10) between the condensing unit and the evaporator coil. Locate the solenoid valve at the outlet end of the liquid line, near the evaporator coil connections, with flow direction arrow pointed at the evaporator coil. Refer to Table 10. (A liquid line solenoid valve is required when the liquid line length exceeds 75 ft [23 m].) This valve prevents refrigerant migration (which causes oil dilution) to the compressor during the off cycle, at low outdoor ambient temperatures. Wire the solenoid in parallel with the compressor contactor coil (see Figs. 9 and
10). This means of electrical control is referred to as solenoid drop control.
