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.

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 charge given is applicable for total tubing lengths up to 25 feet.

NOTE

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

3.5 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 vapor line must be insulated with a minimum of 1/2" foam rubber

insulation. Tape and suspend the refrigerant lines as shown. DO NOT allow tube

metal-to-metal contact. See Fig. 3.

5. Use PVC piping as a conduit for all underground installations as shown in Fig. 4.

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

refrigerant in the vapor 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.

3.6 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 vapor 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.

3.7 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. 6. 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.

Connect the refrigerant lines using the following procedure:

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

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

service port.

wet rag service valve

Fig.6 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 vapor 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 vapor connection at the indoor coil. Braze the

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

line sizing.

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

outdoor unit. The nitrogen flow should be exiting the system from the vapor 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 vapor 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 vapor line, evaporator, and the liquid line, to 350 microns or less.

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 500 microns.

6.0 INTERCONNECTING TUBING

6.1 VAPOR AND LIQUID LINES

Keep all lines sealed until connection is made.

Make connections at the indoor coil first.

Refer to Line Size Information in Tables 2 and 3 for correct size and multipliers to be used to determine capacity for various vapor 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 the unit and 25 feet of standard size interconnecting liquid and vapor lines. For different lengths,adjust the charge as indicated below.

7.3 PROTECTION FUNCTION INTRODUCTION

(Heat pump only)

Sensor T3 (condenser pipe temperature) and T4 (outdoor ambient temperature)

When open-circuit, compressor, outdoor fan motor and reverse valve will be OFF.

T3 149

°

F ,compressor stop working ; T3 140

°

F ,compressor start working.

When T4 < 5

°

F, compressor will stop.If the electrical heater kit is installed in the

indoor unit, the outdoor unit would provide a signal to drive up the heater.

When T4 > 10.4

°

F, compressor will restart.

Discharge temperature protection

When discharge temp. > 275

°

F, compressor will stop.

When discharge temp. < 194

°

F, compressor will restart.

High pressure protection

When high pressure > 638 PSIG, compressor and outdoor fan motor will stop.

When high pressure < 464 PSIG, compressor and outdoor fan motor will restart

(3 minutes delay necessary).

Low pressure protection

Low pressure < 21 PSIG, compressor and outdoor fan motor will stop.

Low pressure > 44 PSIG, compressor and outdoor fan motor will restart

(3 minutes delay necessary).

In stand-by status, the compressor will not start in low pressure protection.

Within 30 mins, if 4 protection cycles occurs.The system will be locked. It will be restore after power cycle.

7.4 DEFROST MODE INTRODUCTION (Heat pump only)

Start-up conditions of defrost mode:

When JUMP switch is set to

“1”(See in Fig 11), the mode will start up in either of the two following conditions:

1. Compressor operating, when T4 is > 28.4

°F and T3 is < 32 °F last for 40 minutes;

2. Compressor operating, when T4 is < 28.4

°F and T3 is < 32 °F last for 50 minutes.

When JUMP switch is set to

“0”:

Compressor operating, when T3 is < 32

°F last for 30 minutes.

Shut-down conditions of defrost mode:

The mode will shut down in either of the two following conditions:

1. The defrosted time lasting for 10 minutes;

2. T3 is

≥ 77 °F.

8.0 CHECKING REFRIGERANT CHARGE

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

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

R-410A will raise pressures (vapor, 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 60F. 2) Indoor temperature between 70F to 100F. 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 heat is used or five (5) minutes if no crank case heat is used.

Follow these steps: 1. Run in cooling mode at least 10 minutes. 2. Measure OUTDOOR

AMBIENT TEMPERATURE within 6 inches of coil. 3. Measure SUCTION LINE PRES-

SURE. 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 SUC-

TION 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 10 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 the unit and 25 feet of standard size interconnecting liquid and vapor lines. For tube lengths over 25ft add the additional refrigerant see 6.1.

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 interconnecting 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.

9.0 WARRANTY

9.1 MAINTENANCE

1.

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. Refer to the furnace or air handler instructions for filter and blower motor maintenance.

4. The indoor coil and drain pan should be inspected and cleaned regularly to assure

proper drainage.

CAUTION

It is unlawful to knowingly vent, release or discharge refrigerant into the open air during repair, service, maintenance or the final disposal of this unit. When the system is functioning properly and the owner has been fully instructed, secure the owner

’s approval.
