INSTALLATION MANUAL

LISTED

This product was manufactured

in a plant whose quality system

is certified/registered as being

in conformity with ISO 9001.

CERTIFICATION APPLIES ONLY

WHEN THE COMPLETE

SYSTEM IS LISTED

WITH ARI.

SECTION I: GENERAL

The outdoor units are designed to be connected to a matching indoor

coil with sweat connect lines. Sweat connect units are factory charged

with refrigerant for the highest sales volume evaporator plus 15 feet of

field supplied lines.

Matching indoor coils are available with a thermal expansion valve or

an orifice liquid feed sized for the most common usage. The orifice size

and/or refrigerant charge may need to be changed for some system

combinations, elevation differences, or total line lengths. See tabular

data sheet provided in unit literature packet for charge requirements.

Refer to Application Data covering “General Piping Recommendations

and Refrigerant Line Length” (Part Number 036-61920-001).

SECTION II: SAFETY

This is a safety alert symbol. When you see this symbol on

labels or in manuals, be alert to the potential for personal

injury.

Understand and pay particular attention to the signal words DANGER,

WARNING, or CAUTION.

DANGER indicates an imminently hazardous situation, which, if not

avoided, will result in death or serious injury

WARNING indicates a potentially hazardous situation, which, if not

avoided, could result in death or serious injury

CAUTION indicates a potentially hazardous situation, which, if not

avoided may result in minor or moderate injury

. It is also used to

alert against unsafe practices and hazards involving only property dam-

age.

INSPECTION

As soon as a unit is received, it should be inspected for possible dam-

age 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

Distributor for more information.

Improper installation may create a condition where the operation of

the product could cause personal injury or property damage.

Improper installation, adjustment, alteration, service, or mainte-

nance can cause injury or property damage. Refer to this manual

for assistance or for additional information, consult a qualified con-

tractor, installer, or service agency.

This product must be installed in strict compliance with the

enclosed installation instructions and any applicable local, state,

and national codes including, but not limited to building, electrical,

and mechanical codes.

R-410A systems operate at higher pressures than R-22 systems.

Do not use R-22 service equipment or components on R-410A

equipment. Service equipment

Must Be Rated for R-410A.

66901 / 035-20393-001 Rev. C (1204) Requirements For Installing/Servicing R-410A Equipment • • • • • • • Gauge sets, hoses, refrigerant containers, and recovery systems must be designed to handle the POE type oils and the higher pressures of R-410A. Manifold sets should be 800 PSIG high side and 250 PSIG low side with 550 PSIG low side retard. All hoses must have a 700 PSIG service pressure rating. Leak detectors should be designed to detect HFC refrigerant.

66901 / 035-20393-001 Rev. C (1204) GROUND INSTALLATION The unit may be installed at ground level on a solid base that will not shift or settle, causing strain on the refrigerant lines and possible leaks. Maintain the clearances shown in Figure 1 and install the unit in a level position. Normal operating sound levels may be objectionable if the unit is placed directly under windows of certain rooms (bedrooms, study, etc.). NOTE: Using a larger than specified line size could result in oil return problems.

66901 / 035-20393-001 Rev. C (1204) Dry nitrogen should always be supplied through the tubing while it is being brazed, because the temperature is high enough to cause oxidation of the copper unless an inert atmosphere is provided. The flow of dry nitrogen should continue until the joint has cooled. Always use a pressure regulator and safety valve to insure that only low pressure dry nitrogen is introduced into the tubing. Only a small flow is necessary to displace air and prevent oxidation.

66901 / 035-20393-001 Rev. C (1204) 7. Install TXV equalizer line in 1/8” hole previously made in vapor line. Equalizer line should not be bottomed out in the vapor line. Insert equalizer line at least 1/4” in the vapor line. Braze equalizer line making sure that tube opening is not brazed closed. 4. Remove the service access panel to gain access to the unit wiring. Route wires from disconnect through power wiring opening provided and into the unit control box. 5.

66901 / 035-20393-001 Rev. C (1204) DEHUMIDIFICATION CONTROL 2. Determine indoor coil adjustment from tabular data sheet. A dehumidification control accessory 2HU06700124 may be used with variable speed air handlers or furnaces in high humidity areas. This control works with the variable speed indoor unit to provide cooling at a reduced air flow, lowering evaporator temperature and increasing latent capacity. The humidistat in this control opens the humidistat contacts on humidity rise.

66901 / 035-20393-001 Rev. C (1204) SECTION VIII: SYSTEM START-UP Maintenance INDICATIONS OF PROPER OPERATION 1. Dirt should not be allowed to accumulate on the outdoor coils or other parts in the air circuit. Clean as often as necessary to keep the unit clean. Use a brush, vacuum cleaner attachment, or other suitable means. 2. The outdoor fan motor is permanently lubricated and does not require periodic oiling. 3.

66901 / 035-20393-001 Rev. C (1204) Comfort AlertTM Diagnostics — The Comfort AlertTM diagnostics module facilitates troubleshooting heat pump and air conditioning system failures. This Comfort AlertTM module is designed only for singlephase systems with scroll compressors that have internal overload protection. By monitoring and analyzing data from the compressor and the thermostat demand, the module can detect the cause of electrical and system related failures without any sensors.
