3.0 UNIT INSTALLATION

3.1 LOCATION

Before starting the installation, select and check the suitability of the location for both the indoor and outdoor unit. Observe all limitations and clearance requirements. The outdoor unit must have sufficient clearance for air entrance to the condenser coil, for air discharge and for service access. See Fig.2

NOTE

For multiple unit installations, units must be spaced a minimum of 18 inches apart. (Coil face to coil face.)

If the unit is to be installed on a hot sun exposed roof or a black-topped ground area, the unit should be raised sufficiently above the roof or ground to avoid taking the accumulated layer of hot air into the outdoor unit.

Provide an adequate structural support.

3.2 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

Fig.2 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.).

Top of unit discharge area must be unrestricted for at least 60 inches above the unit.

WARNING

The outdoor unit should not be installed in an area where mud or ice could cause personal injury or system damage.

Elevate the unit sufficiently to prevent any blockage of the air entrances by snow in areas where there will be snow accumulation. Check the local weather bureau for the expected snow accumulation in your area. Isolate the unit from rain gutters to avoid any possible wash out of the foundation.

3.3 ROOF INSTALLATION

When installing units on a roof, the structure must be capable of supporting the total weight of the unit, including a padded frame unit, rails, etc., which should be used to minimize the transmission of sound or vibration into the conditioned space.

3.4 UNIT PLACEMENT

1. Provide a base in the pre-determined location.

2. Remove the shipping carton and inspect for possible damage.

3. Compressor tie-down nuts should remain tightened.

4. Position the unit on the base provided.

CAUTION

This system uses R410A refrigerant which operates at higher pressure than

R-22. No other refrigerant may be used in this system. Gauge sets, hoses, refrigerant containers, and recovery system must be designed to handle

R410A. If you are unsure, consult the equipment manufacturer.

13 SEER

The outdoor unit must be connected to the indoor coil using field supplied refrigerant grade copper tubing that is internally clean and dry. Units should be installed only with the tubing sizes for approved system combinations. The refrigerant charge shown in the nameplate is for standard size interconnecting liquid line lengths up to 15 feet.

NOTE

Using a larger than specified line size could result in oil return problems. Using a too small line will result in loss of capacity and other problems caused by insufficient refrigerant flow. Slope horizontal suction lines at least 1" every 20 feet toward the outdoor unit to facilitate proper oil return.

3.5 UNIT MOUNTING

If elevating the heat pump, either on a flat roof or on a slab, observe the following guidelines.

1. The base pan provided elevates the heat pump 2” above the base pad.

2 . If elevating a unit on a flat roof , use 4”× 4”(or equivalent) stringers positioned to distribute unit weight evenly and prevent noise and vibration (See Fig.3).

NOTE:Do not block drain openings shown in Fig.3.

3. If unit must be elevated because of anticipated snow fall, secure unit and elevating stand such that unit and/or stand will not tip over or fall off.

NOTE: To tie down unit, see 3.6.

3.7 PRECAUTIONS DURING LINE INSTALLATION

1. Install the lines with as few bends as possible. Care must be taken not to damage

the couplings or kink the tubing. Use clean hard drawn copper tubing where no

appreciable amount of bending around obstruction is necessary, if soft copper must

be used, care must be taken to avoid sharp bends which may cause a restriction.

2. The lines should be installed so that they will not obstruct service access to the coil,

air handling system or filter.

3. Care must also be taken to isolate the refrigerant lines to minimize noise transmis-

sion from the equipment to the structure.

4. The suction line must be insulated. Tape and suspend the refrigerant lines as shown.

DO NOT allow tube metal-to-metal contact. See Fig.5.

5. Use PVC piping as a conduit for all underground installations as shown in Fig.6.

Buried lines should be kept as short as possible to minimize the build up of liquid

refrigerant in the suction line during long periods of shutdown.

6. Pack a sealing material such as perma gum around refrigerant lines where they

penetrate a wall to reduce vibration and to retain some flexibility.

3.8 PRECAUTIONS DURING BRAZING OF LINES

All outdoor unit and evaporator coil connections are copper-to-copper and should be brazed with a phosphorous-copper alloy material such as Silfos-5 or equivalent. DO

NOT use soft solder. The outdoor units have reusable service valves on both the liquid and suction connections. The total system refrigerant charge is retained within the outdoor unit during shipping and installation. The reusable service valves are provided to evacuate and charge per this instruction.

Serious service problems can be avoided by taking adequate precautions to assure an internally clean and dry system.

CAUTION

Dry nitrogen should always be supplied through the tubing while it is being brazed, because the temperature required is high enough to cause oxidation of the copper unless an inert atmosphere is provide. 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.

3.9 PRECAUTIONS DURING BRAZING SERVICE VALVE

Precautions should be taken to prevent heat damage to service valve by wrapping a wet rag around it as shown in Fig.8. Also, protect all painted surfaces, insulation, during brazing. After brazing cool joint with wet rag.

The valve can be opened by removing the plunger cap and fully inserting a hex wrench into the stem and backing out counter-clockwise until valve stem just touches the chamfered retaining wall.

13 SEER

NOTE

Connect the refrigerant lines using the following procedure:

1. Remove the cap and Schrader core from both the liquid and suction service valve

service ports at the outdoor unit. Connect Iow pressure nitrogen to the liquid line

service port. wet rag service valve

Fig.8 Heat Protection

2. Braze the liquid line to the liquid valve at the outdoor unit. Be sure to wrap the valve

body with a wet rag. Allow the nitrogen to continue flowing. Refer to the Tabular Data

Sheet for proper liquid line sizing.

3. Carefully remove the rubber plugs from the evaporator liquid and suction connections

at the indoor coil.

4. Braze the liquid line to the evaporator liquid connection. Nitrogen should be flowing

through the evaporator coil.

5. Slide the plastic cap away from the suction connection at the indoor coil. Braze the

suction line to the evaporator suction connection. Refer to the Table 1 for proper

suction line sizing.

6. Protect the suction valve with a wet rag and braze the suction line connection to the

outdoor unit. The nitrogen flow should be exiting the system from the suction service

port connection. After this connection has cooled, remove the nitrogen source from

the liquid fitting service port.

7. Replace the Schrader core in the liquid and suction valves.

8. Leak test all refrigerant piping connections including the service port flare caps to be

sure they are leak tight.

DO NOT OVER TIGHTEN (between 40 and 60 inch -lbs.

maximum).

9. Evacuate the suction line, evaporator, and the liquid line, to 350 microns or less.

10. Replace cap on service ports. Do not remove the flare caps from the service ports

except when necessary for servicing the system.

11. Release the refrigerant charge into the system. Open both the liquid and suction

valves by removing the plunger cap and with an hex wrench back out counter

-clockwise until valve stem just touches the chamfered retaining wall.

12. Replace plunger cap finger tight, then tighten an additional 1/12 turn (1/2 hex flat).

Cap must be replaced to prevent leaks.

WARNING

Never attempt to repair any brazed connections while the system is under pressure. Personal injury could result.

See "System Charge" section for checking and recording system charge.

4.0 INTERCONNECTING TUBING

4.1 SUCTION AND LIQUID LINES

Keep all lines sealed until connection is made.

Make connections at the indoor coil first.

Refer to Li ne Size Information in Ta bles 2 and 3 for correct size and multipliers to be used to determine capacity for various suction line diameters and lengths of run. The losses due to the lines being exposed to outdoor conditions are not included.

The factory refrigerant charge in the outdoor unit is sufficient for 15 feet of standard size interconnecting liquid line. Calculate actual charge required with installed liquid line size and length as below.

1/4” ± .2 oz. per foot

5/16” ± .4 oz. per foot

3/8” ± .6 oz . per foot

1/2” ± 1.2 oz . per foot

4.2 MAXIMUM LENGTH OF LINES

T h e maximum length of interconnecting line is 150 feet.

Always use the shortest length possible with a minimu m number of bends.

NOTE: Excessively long refrigerant lines cause loss of equipment capacity.

4.3 VERTICAL LIFT

Keep the vertical lift to a minimum. Use the following guidelines when installing the unit:

1. DO NOT exceed the vertical lift as indicated on Table 3.

2. It is recommended to use the smallest liquid line size permitted to minimize sys - t em charge which will maximize compressor reliability.

3. Table 3 may be used for sizing horizontal runs.

5.0 EVACUATION

It will be necessary to evacuate the system to 350 microns or less. If a leak is suspected, leak test with dry nitrogen to locate the leak. Repair the leak and test again.

To verify that the system has no leaks, simply close the valve to the vacuum pump suction to isolate the pump and hold the system under vacuum. Watch the micron gauge for a few minutes. If the micron gauge indicates a steady and continuous rise, it's an indication of a leak. If the gauge shows a rise, then levels off after a few minutes and remains fairly constant, its an indication that the system is leak free but still contains moisture and may require further evacuation if the reading is above 350 microns.

Using suction line larger than shown in chart will result in poor oil return and is not recommended. the system capacity published in AHRI is 17800Btu/h. This data is based on the AHRI test condition and 25ft line set with standard suction tube size(3/4" tube). If you need to add the line set more than 25ft or use the optional suction tube size, you need to recalculate the capacity with the coefficient in the table. For example: for 50ft line and 5/8" suction tube, the capacity will be 17800*0.97=17266Btu/h.

7.0 SYSTEM OPERATION

7.1 COMPRESSOR CRANKCASE HEATER (CCH) (Heat pump only)

Refrigerant migration during the off cycle can result in a noisy start up. Add a crankcase heater to minimize refrigeration migration, and to help eliminate any start up noise or bearing “wash out”.

All heaters must be located on the lower half of the compressor shell. Its purpose is to drive refrigerant from the compressor shell during long off cycles, thus preventing damage to the compressor during start-up.

The crankcase heating start condition:

1.The crankcase heating start must meet two conditions:

A. Outdoor temperature

41° F.

B. Compressor stops working more than 3 hours.

2. Outdoor temperature < 41° F and just connected to the power source.

The crankcase heating stop must meet condition:

Outdoor temperature

44.6° F or compressor start.

3. Compressor stop operating;

4. T3 is ≥ 77 °F last for 60s when T4 < 28.4 °F.

8.0 CHECKING REFRIGERANT CHARGE

Charge for all systems should be checked against the Charging Chart inside the access corner panel or Charging by weight.

IMPORTANT:Do not operate the compressor without charge in system. Additio n of

R - 410A will raise pressures (suction, liquid and discharge).

8.1 CHARGING BY LIQUID PRESSURE

In order to properly charge the system, the following conditions must be met:

1) Outdoor temperature above 60°F.

2) Indoor temperature between 70°F to 100°F.

3) Installation must be complete with brazed joints and drier visually inspected.

4) The unit electrical installation must be checked and unit powered for one (I) hour if crank case heater is used or five (5) minutes if no crankcase heater is used.

Follow these steps:

1. Run in cooling mode at least 20 minutes.

2. Measure OUTDOOR AMBIENT TEMPERATURE within 6 inches of coil.

3. Measure SUCTION LINE PRESSURE.

4. Find the TARGET LIQUID PRESSURE at the intersection between the SUCTION

LINE PRESSURE and the OUTDOOR AMBIENT TEMPERATURE, if falls between rows or columns then estimate the TARGET LIQUID PRESSURE or SUCTION LINE

PRESSURE falls between rows or columns then estimate the TARGET LIQUID

PRESSURE between the rows and columns.

5. Compare the measured LIQUID LINE PRESSURE to the TARGET LIQUID

PRESSURE, add charge to raise the pressure or recover charge to lower it.

6. After running unit for 20 minutes if the SUCTION LINE PRESSURE changes, go back to step 2 otherwise remove test equipment and cover the valves.

8.2 CHARGING BY WEIGHT

For a new installation,evacuation of interconnecting tubing and indoor coil is adequate; otherwise,evacuate the entire system. The factory refrigerant charge in the outdoor unit is sufficient for 15 feet of standard size interconnecting liquid line. Calculate actual charge required with installed liquid line size and length , please see 4.1 of instruction.

With an accurate scale (+/- 1 oz.) adjust charge difference between that shown on the unit data plate and that calculated for the new system Installation. if the entire system has been evacuated, add the total calculated charge.

8.3 FINAL LEAK TESTING

After the unit has been properly evacuated and charged, a halogen leak detector should be used to detect leaks in the system. All piping within the condensing unit, evaporator, and interconnec ting tubing should be checked for leaks. If a leak is detected, the refrigerant should be recovered before repairing the leak. The Clean Air

Act prohibits releasing refrigerant into the atmosphere .

Step 1: Remove the screws and front coil panel.

Step 2: Remove the rubber plugs from the liquid and vapor lines.

Step 3: Using a back up wrench and loosen the fl ow assembly. Remove the factory installed piston Reassemble and tighten the fl ow assembly. Tighten the fl ow assembly to 11 (±2) ft-lb

Step 4: If replacing the preinstalled ori fi ce with the optional ori fi ce, ensure the replacement ori fi ce is placed in the same orientation as the preinstalled ori fi ce before tightening the fl ow assembly.

TX V

TXV-Speci fi c Steps

Step 5: Drill a small hole in the suction line for the TXV equalizer line. The hole must be on top as noted in the picture.

Step 6: Dry fi t the TXV to the liquid line entering the coil. The valve must be in the upright position as pictured. Keep the valve as close to the coil as possible, although a short piece of fi eld fabricated tubing may be needed. The TXV must be mounted in the CORRECT direction of fl ow. Place the TXV equalizer line 3 to 4 mm inside the small hole drilled in the vapor line.

Step 7: Wrap the TXV and coil panel with a wet rag to prevent overheating while brazing. Use a nitrogen fl ow and braze all connections.

Step 8: Allow tubing to cool and pressurize line sets with 150 PSI of nitrogen to check braze connections and fl ow assembly for leaks. Make repairs as needed.

Step 9: Locate and clean a straight section of the vapor line as close to the coil as possible. Use the supplied copper straps to secure the TXV sensing bulb on top of the vapor line as pictured.

Step 10: Insulate the entire vapor line and sensing bulb It is also recommended to insulate the TXV and liquid line between the valve and coil to prevent condensation in hot humid environments.

Step 11: Replace the front coil panel and secure in place.

Step 12: Follow the steps in the installation guide for vacuum requirements and system start up procedures.

Step 13: Allow system to run for a minimum of 10 minutes in the cooling mode.

A : For fi xed ori fi ce installation: Use the superheat charging chart to obtain proper superheat based on indoor / outdoor conditions.

B : For TXV installation: Charge the system to 10 degrees of subcooling.

Adjust the expansion valve to achieve 9 (± 3 degrees) of superheat.

Step 14: Allow system to run for an additional 10 minutes to verify the subcooling and superheat readings.
