F-GAS REGULATION (EC) No 842 / 2006

When Wiring

ELECTRICAL SHOCK CAN CAUSE SEVERE PERSONAL INJURY OR DEATH. ONLY A QUALIFIED, EXPERIENCED ELECTRICIAN SHOULD ATTEMPT TO WIRE THIS SYSTEM.

SPECIAL PRECAUTIONS

This symbol refers to a hazard or unsafe practice which can result in severe personal injury or death.

This symbol refers to a hazard or unsafe practice which can result in personal injury or product or property damage.

CAUTION

WARNING

Important! Please Read Before Starting

This air conditioning system meets strict safety and operating standards. As the installer or service person, it is an important part of your job to install or service the system so it operates safely and efficiently.

For safe installation and trouble-free operation, you must:

Carefully read this instruction booklet before beginning. Follow each installation or repair step exactly as shown. Observe all local, state, and national electrical codes. Pay close attention to all warning and caution notices given in this manual.

If Necessary, Get Help

These instructions are all you need for most installation

sites and maintenance conditions. If you require help for

a special problem, contact our sales/service outlet or your certified dealer for additional instructions.

In Case of Improper Installation

The manufacturer shall in no way be responsible for improper installation or maintenance service, including failure to follow the instructions in this document.

Do not supply power to the unit until all wiring and tubing are completed or reconnected and checked. Highly dangerous electrical voltages are used in this system. Carefully refer to the wiring diagram and these instructions when wiring. Improper connections and

inadequate grounding can cause accidental injury or

death. Ground the unit following local electrical codes. Connect all wiring tightly. Loose wiring may cause overheating at connection points and a possible fire hazard. Install a protective leakage breaker depending on the installation location (especially a damp or humid location). If a leakage breaker is not installed, electric shock can occur.

When Transporting

Be careful when picking up and moving the indoor and outdoor units. Get a partner to help, and bend your knees when lifting to reduce strain on your back. Sharp edges or thin aluminum fins on the air conditioner can cut your fingers.

When Installing

In a Ceiling or Wall

Make sure the ceiling/wall is strong enough to hold the unit’s weight. It may be necessary to construct a strong wood or metal frame to provide added support.

In a Room

Properly insulate any tubing run inside a room to prevent "sweating" that can cause dripping and water damage to walls and floors.

In Moist or Uneven Locations

Use a raised concrete pad or concrete blocks to provide a solid, level foundation for the outdoor unit. This prevents water damage and abnormal vibration.

In an Area with High Winds

Securely anchor the outdoor unit down with bolts and a metal frame. Provide a suitable air baffle.

In a Snowy Area (for Heat Pump-type Systems)

Install the outdoor unit on a raised platform that is higher than drifting snow. Provide snow vents.

When Connecting Refrigerant Tubing

Use the flare method for connecting tubing. Apply refrigerant lubricant to the matching surfaces of the flare and union tubes before connecting them, then

tighten the nut with a torque wrench for a leak-free

connection. Check carefully for leaks before starting the test run.

When Servicing

Turn the power off at the main power box (mains) before opening the unit to check or repair electrical parts and wiring. Keep your fingers and clothing away from any moving parts. Clean up the site after you finish, remembering to check that no metal scraps or bits of wiring have been left inside the unit being serviced.

Others

Ventilate any enclosed areas when installing or testing the refrigeration system. Escaped refrigerant gas, on contact with fire or heat, can produce dangerously toxic gas. Confirm upon completing installation that no refrigerant gas is leaking. If escaped gas comes in contact with a stove, gas water heater, electric room heater or other heat source, it can produce dangerously toxic gas.

Outdoor Unit SAP-CMRV1426EH

Insulation of Refrigerant Tubing

Because capillary tubing is used in the outdoor unit, both the wide and narrow tubes of this air conditioner become cold. To prevent heat loss and wet floors due to dripping of condensation, both tubes must be well insulated with a proper insulation material. The thickness of the insulation should be a min. 8 mm.

After a tube has been insulated, never try to bend it into a narrow curve because it can cause the tube to break or crack.

7. FUNCTIONS

7-1. Explanation of Functions

The numerical values such as temperature, frequency, time and current in parentheses are an example

of SAP-CMRV3146EH and the values are different from the other models.

Control/conditions

INITIAL

Breaker is ON. Power is supplied to the indoor and outdoor unit

control circuits, however the unit remains stopped. Positioning of the outdoor unit electric expansion valve is performed.

The ON/OFF operation button on the remote controller is pressed.

If automatic operation mode has been selected with the remote controller, operation begins in

HEAT, SENSOR DRY, or COOL mode

depending on the room temperature and outdoor temperature at the time operation starts.

Depending on the operational mode, refer to the HEAT, SENSOR DRY, or COOL item.

This applies in the case of automatic HEAT/COOL operation.

HEAT

Unit operation Explanation

The ON/OFF operation button on the remote controller is pressed.

The unit is forced to stop for 3 minutes after  the power is turned ON, or 3 minutes after the compressor stops, in order to protect the compressor.

The frequency is increased at the rate of 1 Hz

every 0.5 seconds.

Operation lamp illuminates.

Indoor fan is stopped to prevent cold air from being emitted.

Outdoor unit begins operating after forced-stop is canceled.

This is in order to stabilize the return of oil to the compressor.

When the frequency reaches Hz,frequency

increases are stopped for a period of seconds.

(Refor to Table 2 "Freguency control".)

If the indoor and outdoor temperatures are high, the current peak cut-off activates, stopping any

increases in frequency.

The frequency then increases.

The thermostat turns OFF.

The outdoor unit stops. (It does not stop if the thermostat for another indoor unit is ON.)

Approximately 30 seconds after the thermostat turns OFF, the indoor fan is stopped.

The indoor fan is stopped.

The indoor and outdoor temperatures are high.

The outdoor unit starts automatically after 3 minutes.

During these 3 minutes, a low-pressure pressure balance is achieved, allowing the compressor to start more easily.

In order to protect the compressor, the outdoor unit will not operate for 3 minutes after the thermostat turns OFF, even if the room temperature drops below the desired temperature.

The room temperature has reached the desired temperature.

Operating frequency is stabilized in order to

maintain a comfortable environment.

The indoor temperature and the remote controller temperature setting are

approximately equal.

The thermostat turns ON. The unit operated before, and the temperature of

the indoor heat exchanger is relatively warm. Therefore,the fan speed may start at the set fan speed at the same time that the thermostat turns ON.

The indoor unit is stopped.

Depending on the relationship between the remote controller temperature setting and the room temperature, the compressor may stop temporarily (in other words, the thermostat may turn OFF).

When the indoor coil temperature rises,

the compressor starts,

the outdoor fan starts,

and the indoor fan changes from "LL" to the set fan speed.

The amount of heat pump exceeds the amount of heat radiation from the room. Therefore, there is no need to further increase

the compressor capacity, and the frequency is

stabilized or lowered.

The frequency is not increased, even if

there is a difference between the room temperature and the desired temperature.

In some cases, the frequency may be

decreased.

NOTE

64

Control/conditions

[Clean defrost]

Defrost is performed when the outdoor unit is stopped, and the temperature of the outdoor unit coil is at or below the L1 line.

(Refer to Fig. 1.)

All indicator lamps turn OFF. The indoor and outdoor units stop.

The operating frequency during defrost is 80 Hz. (Frequency is lowered if the current

peak cut-off function is activated.)

The maximum length of a single defrost operation is 12 minutes.

For the outdoor heat exchanger temperature conditions for ending defrost, refer to Table 1.

Operation is restarted within 4 hours (only when AUTO mode is selected with the remote controller).

Within 4 hours after operation was stopped, it is assumed that there has been no significant change in the indoor and outdoor temperatures, and the previous conditions (HEAT) are stored.

8. TROUBLESHOOTING

8-1. Precautions before Performing Inspection or Repair

Both the indoor unit and outdoor unit include electronic control circuits.  Be sure to pay attention to the following before inspecting or repairing the outdoorside electronic circuits.

High-capacity electrolytic capacitors are used inside the outdoor unit controller (inverter). They retain an

electrical charge (charging voltage DC 311 V) even after the power is turned OFF, and some time is required

for the charge to dissipate.

Be careful not to touch any electrified parts before the control circuit board Power Lamp (red) turns OFF.

If the outdoor control circuit board is normal, approximately 180 seconds will be required for the charge to

dissipate. However, allow at least 30 minutes for the charge to dissipate if it is thought there might be trouble with the outdoor control circuit board.

For example, if the outdoor control circuit board fuse has blown, approximately 30 minutes will be required to

discharge the high-capacity electrolytic capacitors.

71

8-2. Trouble Diagnosis by Error Monitor Lamps

WARNING

To prevent electric shock, do not inspect or repair until the Power Lamp on the P.C.Board is turned off.

8-2-1. Location of the Error Monitor Lamps

Remove the top plate of outdoor unit and the cover of Electrical Component Box. The Power Lamp and Error Monitor Lamps are located on the P.C.Board of Electrical Component Box. (Fig.1)

Check that the sensor is securely contained in the thermostat holder.

(9) Breaker

Check whether or not the breaker has been tripped.

Check that the breakers and fuses used are of the specified capacity.

Check that the breaker and its line are exclusive for A/C use.

(10) Refrigerant gas pressure

Start a COOL test run, and messure the temperatures of the A/C intake air and discharge air. Compare the values with the performance charts.

If the values are higher than the performance charts: Check for refrigerant shortage or blockage of the refrigerant circuit.

< Assessment of refrigerant shortage >

1. The pressure in the low-pressure section is 5 MPa or more below the value in the performance charts.

2. There is little condensation on the indoor heat exchanger, which overall appears dry.

< Distinguishing between refrigerant shortage and refrigerant circuit blockage >

If the pressure in the low-pressure section does not change when the circuit is charged 2 to 3 times with refrigerant gas (0.44 lbs each time), or if the change is small, then the problem may not be refrigerant shortage. The problem may be a blockage of the refrigerant circuit.

1. Check that there is no internal leakage inside the 4-way valve:

At the low-pressure side tubing, check that there is no temperature difference between the intake and discharge of the 4-way valve.

2. Check that the electric expansion valve is not blocked. Check as described on the preceding page.

8-5. Trouble Diagnosis of Fan Motor

This outdoor DC fan motor contains an internal control PCB. Therefore, it is not possible to measure the coil resistance, and the following procedure should be used to check the motor. Perform the trouble diagnosis by Test Run mode described on Installation Instructions of indoor unit.

[Trouble symptom 1] The fan does not stop when the outdoor unit stops. Outdoor unit controller trouble

[Trouble symptom 2] The fan motor does not rotate when the outdoor unit is operating.

(Diagnostic procedure)

* Disconnect the motor connectors and measure the voltage at the DC motor connectors on the outdoor

unit controller (3 locations).

(Diagnostic results)

All of the above measured values are normal. Fan motor trouble (Replace the motor.) Any one of the above measured values is not normal. Outdoor unit controller trouble

(Replace the controller .)

(Reference) DC motor connector pin arrangement

[Trouble symptom 3] Motor rotates for some time (several seconds), but then quickly stops, when the outdoor

unit operates. (There is trouble in the system that provides feedback of motor rotation speed from the motor to the outdoor unit controller.)

[Trouble symptom 4] Fan motor rotation speed does not change during outdoor unit operation.

[Trouble symptom 5] Fan motor rotation speed varies excessively during outdoor unit operation.

(Remedy for symptom 3 to 5)

It is not possible to identify whether the trouble is outdoor unit controller trouble or motor trouble. Therefore, first replace the outdoor unit controller, then (if necessary) replace the DC motor.

Important:

(A) Turn OFF the power before connecting or disconnecting the motor connectors. (B) When performing voltage measurement at the outdoor controller connector for (3) in the table

below, the DC motor will trip and voltage output will stop approximately 10 seconds after operation is started. For this reason, to measure the voltage again, first turn OFF the outdoor unit power, then, measure the voltage in Test Run mode.

9. REFRIGERANT R410A: SPECIAL PRECAUTIONS WHEN SERVICING UNIT

9-1. Characteristics of New Refrigerant R410A

9-1-1. What is New Refrigerant R410A?

R410A is a new refrigerant that contains two types of pseudo-non-azeotropic refrigerant mixture. Its refrigeration capacity and energy efficiency are about the same level as the conventional refrigerant, R22.

9-1-2. Components (mixing proportions)

HFC32 (50%) / HFC125 (50%)

9-1-3. Characteristics

Less toxic, more chemically stable refrigerant

The composition of refrigerant R410A changes whether it is in a gaseous phase or liquid phase. Thus, when

there is a refrigerant leak the basic performance of the air conditioner may be degraded because of a change in composition of the remaining refrigerant. Therefore, do not add new refrigerant. Instead, recover the remaining refrigerant with the refrigerant recovery unit. Then, after evacuation, totally recharge the specified

amount of refrigerant with the new refrigerant at its normal mixed composition state (in liquid phase).

When refrigerant R410A is used, the composition will differ depending on whether it is in gaseous or liquid

phase, and the basic performance of the air conditioner will be degraded if it is charged while the refrigerant is in gaseous state. Thus, always charge the refrigerant while it is in liquid phase.

9-2. Checklist before Servicing

Use a clutch-type flare tool for R410A or the conventional flare tool. Note that sizes of the resultant flares differ between these two tools. Where a conventional flare tool is used, make sure to observe A Specification (amount of extrusion) by using the flare spacer.

Size of flare

Ether-type oil is used for compressor oil for R410A-type units, which is different from the mineral oil used for R22. Thus more attention to moisture prevention and faster replacement work compared with conventional models are required.

CAUTION

Tubing precautions

Refrigerant R410A is more easily affected by dust or moisture compared with R22, thus be sure to temporarily cover the ends of the tubing with caps or tape prior to installation.

Never use 0.7mm-thick copper tubing or tubing which is less than 0.8mm in thickness, since air conditioners with R410A are subject to higher pressure than those using R22 and R407C.

No addition of compressor oil for R410A

No additional charge of compressor oil is permitted.

No use of refrigerant other than R410A

Never use a refrigerant other than R410A.

If refrigerant R410A is exposed to fire

Through welding, etc., toxic gas may be released when R410A refrigerant is exposed to fire. Therefore, be sure to provide ample ventilation during installation work.

Caution in case of R410A leak

Check for possible leak points with the special leak detector for R410A. If a leak occurs inside the room, immediately provide thorough ventilation.

CAUTION

The above tools specifically for R410A must not be used for R22 and R407C. Doing so will cause malfunction of the unit.

For the above vacuum pump (*1, *2) and vacuum pump adapter (*3), those for R22-type units can be used for R410A-type. However, they must be used exclusively for R410A and never alternately with R22 and R407C.

For details on tubing installation procedures, refer to the installation manuals attached to the indoor unit and outdoor unit.

NOTE

To prevent other refrigerants (R22, R407C) from being mistakenly charged to this unit, shape and external diameter of the service port screw has been altered. <External diameter of service port>  R410A : 7.94 mm (5/16")  R22, R407C : 6.35 mm (1/4")

9-4. Tubing Installation Procedures

When the tubes are connected, always apply HAB oil on the flare portions to improve the sealing of tubing.

The following is the HAB oil generally used:

Esso: ZERICE S32

80

9-5. In Case of Compressor Malfunction

CAUTION

Should the compressor malfunction, be sure to make the switch to a replacement compressor as quickly as possible.

Use only the tools indicated exclusively for R410A. See "9-3. Tools Specifically for R410A."

9-5-1. Procedure for Replacing Compressor

(1) Recovering refrigerant

Any remaining refrigerant inside the unit should not be released to the atmosphere, but recovered using the refrigerant recovery unit for R410A.

Do not reuse the recovered refrigerant, since it will contain impurities.

(2) Replacing Compressor

Soon after removing seals of both discharge and suction

tubes of the new compressor, replace it quickly.

(3) Checking for sealing

Use nitrogen gas for the pressurized gas, and never use a refrigerant other than R410A. Also do not use oxygen or any flammable gas.

(4) Evacuation

Use a solenoid valve-installed vacuum pump so that

even if power is cut off in the middle of evacuation of air due to a power interruption, the valve will prevent the pump oil from flowing back.

The equipment may be damaged if moisture remains in

the tubing, thus carry out the evacuation thoroughly.

CAUTION

Never charge a large amount of liquid refrigerant at once to the unit. This may cause damage to the compressor.

CAUTION

To prevent the composition of R410A from changing, never bleed the refrigerant gas into the atmosphere while transferring the refrigerant. (Fig. 3)

(5) Recharging

Be sure to charge the specified amount of refrigerant in liquid state using the service port

of the wide tube service valve. The proper amount is listed on the unit's nameplate.

When the entire amount cannot be charged all at once, charge gradually while operating the unit in Cooling Operation.

When charging with a refrigerant cylinder, use an electronic scale for charging refrigerant. In this case, if the volume of refrigerant in the cylinder becomes less than 20% of the fully-charged amount, the composition of the refrigerant starts to change. Thus, do not use the refrigerant if

the amount in the charging cylinder is less than 20%.

Also, charge the minimum necessary amount to the charging cylinder before using it to charge the air conditioning unit.

Example:

In case of charging refrigerant to a unit requiring

0.76Kg using a capacity of a 10Kg cylinder, the minimum necessary amount for the cylinder is:

0.76 + 10 0.20 = 2.76Kg

For the remaining refrigerant, refer to the instructions of the refrigerant manufacturer.

If using a charging cylinder, transfer the specified

amount of liquid refrigerant from the refrigerant

cylinder to the charging cylinder.

Prepare an evacuated charging cylinder beforehand.

Do not use the refrigerant if the amount in the charging cylinder is less than 20%.

9-6. In Case Refrigerant is Leaking

CAUTION

Never attempt to charge additional refrigerant when refrigerant has been leaking from the unit. Follow the procedure described below to locate points of leaks and carry out repairs, then recharge the refrigerant.

(1) Detecting Leaks

Use the detector for R410A to locate refrigerant leak points.

(2) Recovering refrigerant

Never release the gas to the atmosphere; recover residual refrigerant using the refrigerant recovery unit for R410A, instead.

Do not reuse the recovered refrigerant because its composition will have been altered.

(3) Welding leaking points

Confirm again that no residual refrigerant exists in the unit before starting welding.

Weld securely using flux and wax for R410A.

Prevent oxide film from forming inside the tubes utilizing substitution with nitrogen (N2) in the refrigerant circuit of the unit. Leave ends of tubes open during welding.

(4) Checking for sealing

Use nitrogen gas for the pressurized gas, and never use a refrigerant other than R410A. Also do not use oxygen or any flammable gas.

(5) Evacuation

Use a solenoid valve-installed vacuum pump so that

even if power is cut off in the middle of evacuation of air due to a power interruption, the valve will prevent the pump oil from flowing back.

The equipment may be damaged if moisture remains in

the tubing, thus carry out the evacuation thoroughly.

9-7. Charging Additional Refrigerant

9-7-1. When Tubes are Extended

Observe the proper amount of refrigerant as stated in this service manual or the installation manual that came with the indoor unit. Charge additional refrigerant in liquid state only.

9-8. Retro-Fitting Existing Systems

9-8-1. Use of Existing Units

Never use new refrigerant R410A for existing units which use R22. This will cause the air conditioner to

operate improperly and may result in a hazardous condition.

9-8-2. Use of Existing Tubing

If replacing an older unit that used refrigerant R22 with a R410A unit, do not use its existing tubing. Instead, completely new tubing must be used.

CAUTION

Never charge additional refrigerant if refrigerant is leaking from the unit. Follow instructions given in "9-6. In Case Refrigerant is Leaking" and completely carry out repairs. Only then should you recharge the refrigerant.

If Necessary, Get Help

These instructions are all you need for most installation sites and maintenance conditions. If you require help for a special problem, contact our sales/service outlet or your certified dealer for additional instructions.

In Case of Improper Installation

The manufacturer shall in no way be responsible for improper installation or maintenance service, including failure to follow the instructions in this document.

SPECIAL PRECAUTIONS

When Wiring

ELECTRICAL SHOCK CAN CAUSE SEVERE PERSONAL INJURY OR DEATH. ONLY A QUALIFIED, EXPERIENCED ELECTRICIAN SHOULD ATTEMPT TO WIRE THIS SYSTEM.

• Do not supply power to the unit until all wiring and tub-

ing are completed or reconnected and checked.

• Highly dangerous electrical voltages are used in this

system. Carefully refer to the wiring diagram and these instructions when wiring. Improper connections and inadequate grounding can cause accidental

injury or death.

• Ground the unit following local electrical codes.

• Connect all wiring tightly. Loose wiring may cause

overheating at connection points and a possible fire hazard.

• Install a protective leakage breaker depending on the

installation location (especially a damp or humid location). If a leakage breaker is not installed, electric shock can occur.

When Transporting

Be careful when picking up and moving the indoor and

outdoor units. Get a partner to help, and bend your knees when lifting to reduce strain on your back. Sharp edges or thin aluminum fins on the air conditioner can cut your fingers.

When Installing…

…In a Ceiling or Wall

Make sure the ceiling/wall is strong enough to hold the unit’s weight. It may be necessary to construct a strong wood or metal frame to provide added support.

…In a Room

Properly insulate any tubing run inside a room to prevent “sweating” that can cause dripping and water damage to walls and floors.

…In Moist or Uneven Locations

Use a raised concrete pad or concrete blocks to provide a solid, level foundation for the outdoor unit. This prevents water damage and abnormal vibration.

…In an Area with High Winds

Securely anchor the outdoor unit down with bolts and a metal frame. Provide a suitable air baffle.

…In a Snowy Area (for Heat Pump-type Systems)

Position the outdoor unit in a protected location

•

where snow will not blow into it.

• Install the outdoor unit on a raised platform that is

higher than drifting snow. Provide snow vents.

When Connecting Refrigerant Tubing

• Use the flare method for connecting tubing.

• Apply refrigerant lubricant to the matching surfaces of the flare and union tubes before connecting them, then tighten the nut with a torque wrench for a leak-free connection.

• Check carefully for leaks before starting the test run.

When Servicing

• Turn the power OFF at the main power box (mains) before opening the unit to check or repair electrical parts and wiring.

• Keep your fingers and clothing away from any moving parts.

• Clean up the site after you finish, remembering to check that no metal scraps or bits of wiring have been left inside the unit being serviced.

Others

• Ventilate any enclosed areas when installing or testing the refrigeration system. Escaped refrigerant gas, on contact with fire or heat, can produce dangerously toxic gas.

• Confirm upon completing installation that no refrigerant gas is leaking. If escaped gas comes in contact with a stove, gas water heater, electric room heater or other heat source, it can produce dangerously toxic gas.

• Do not install only a single indoor unit.

3-2. Drain Cap and Drain Elbow

First refer to Section 2. Installation Site Selection.

NOTE

The drain hole at the bottom of the outdoor unit was not plugged at the time of factory shipment. If necessary, plug the drain hole with the accessory drain cap or mount the accessory drain elbow before installing the outdoor unit. (Fig. 7)

When installing in a cold area where drainage water may freeze, do not attach the provided drain cap or drain elbow to the bottom plate of the unit.

3-3. Use of the Flaring Method

Many of the conventional split system air conditioners employ the flaring method to connect refrigerant tubes which run between indoor and outdoor units. In this method, the copper tubes are flared at each end and connected with flare nuts.

3-4. Flaring Procedure with a Flare Tool

(1) Cut the copper tube to the required length with a

tube cutter. It is recommended to cut approx. 30 – 50 cm longer than the tubing length you estimate.

(2) Remove burrs at the end of the copper tube with a

tube reamer or file. This process is important and should be done carefully to make a good flare. (Fig. 8)

NOTE

A good flare should have the following characteristics:

G inside surface is glossy and smooth. G edge is smooth. G tapered sides are of uniform length.

3-5. Caution Before Connecting Tubes Tightly

a) Be sure to apply a sealing cap or water-proof tape to

prevent dust or water from getting into the tubes before they are used.

b) Be sure to apply refrigerant lubricant to the matching

surfaces of the flare and union before connecting them together. This is effective for reducing gas leaks. (Fig. 12)

3-7. Insulation of Refrigerant Tubing

English

To prevent heat loss and wet floors due to dripping of condensation, both tubes must be well insulated with a

proper insulation material.

The thickness of the insulation should be a minimum 8 mm. (Fig. 17)

Fig. 15

Fig. 16

Insulation

3-8. Taping the Tubes

After a tube has been insulated, never try to bend it into a narrow curve, as this may cause the tube to break or crack.

(1) At this time, the 2 refrigerant tubes (and electrical wire

if local codes permit) should be taped together with armoring tape. The drain hose may also be included and taped together as 1 bundle with the tubing.

(2) Wrap the armoring tape from the bottom of the outdoor

unit to the top of the tubing where it enters the wall. As you wrap the tubing, overlap half of each previous tape turn. (Fig. 18)

(3) Clamp the tubing bundle to wall, using 1 clamp approx.

every 120 cm.

Do not wind the armoring tape too tightly, since this will decrease the heat insulation effect. Also, be sure the condensation drain hose splits away from the bundle and drips clear of the unit and the tubing.

4. Air Purging

CAUTION

Air and moisture remaining in the refrigerant system have undesirable effects as indicated below. Therefore, they must be purged completely.

G pressure in the system rises G operating current rises G cooling efficiency drops G moisture in the air may freeze and block capillary

tubing

G water may lead to corrosion of parts in the

refrigerant system

Air Purging with a Vacuum Pump

I

(for Test Run)

G In order to protect the earth’s environment, be sure to

use a vacuum pump to perform the air purge. (Never perform an air purge by using the refrigerant gas cylinder or other external gas, or by using the gas inside the outdoor unit.) Perform the air purge for tubes A and B. Use the same procedures for all tubes.

In order to prevent charging errors with the air conditioner that uses R410A, the screw diameter at the service valve charging port has been changed. When recharging or performing other servicing, use the special charging hose and manifold gauge.

(1) Check that each tube (both narrow and wide

tubes) between the indoor and outdoor units have been properly connected and all wiring for the test run has been completed. Note that both narrow and wide tube service valves on the outdoor unit are kept closed at this stage.

(2) Using an adjustable wrench or box wrench,

remove the valve caps from the service valve on both narrow and wide tubes.

(3) Connect a vacuum pump and a manifold valve

(with pressure gauges) to the service port on the wide tube service valve. (Fig. 20).

Before using the vacuum pump adapter, read the vacuum pump adapter manual, and use the adapter correctly.

Be sure to use a manifold valve for air purging. If it is not available, use a stop valve for this purpose. The “Hi” knob of the manifold valve must always be kept closed.

G When using a hex wrench to open the spindle, an

extremely small amount of refrigerant may leak. This does not indicate a problem.

G Use a hex wrench of a type to which force can be

easily applied.

11

(4) With the “Lo” knob of the manifold valve open and

CAUTION

high-pressure valve (“Hi”) closed completely, run the vacuum pump. Run the pump until the pressure is –101 kPa (–76 cmHg). The operation time for the vacuum pump varies with tubing length and the capacity of the pump. The following table shows the amount of time required for evacuation:

Table 5

English

Required time for evacuation when capacity

of 100 liter/h vacuum pump is used

20 min. or more

NOTE

The required time in the above table is calculated based on the assumption that the ideal (or target) vacuum condition is around 10 mmHg abs.

(5) With the vacuum pump still running, close the “Lo”

knob of the manifold valve. Then stop the vacuum pump. Fully close the low-pressure valve and stop the vacuum pump. (Wait 1 – 2 minutes and check that the manifold gauge pointer does not return. If it does return, find and repair the leak, then apply the vacuum again.)

(6) With a hex wrench, turn the valve stem on the nar-

row tube service valve counter-clockwise by 90 degrees (1/4 turn) for 10 seconds, and then turn the stem clockwise to close it again.

Be sure to completely insert the hex wrench before attempting to turn the valve.

(7) With a standard screwdriver, turn the wide tube

service valve stem counterclockwise to fully open the valve.

(8) Turn the narrow tube service valve stem counter-

clockwise to fully open the valve.

(9) Loosen the vacuum hose connected to the wide

tube service port slightly to release the pressure. Then, remove the hose.

(10) Leak test all joints at the tubing (both indoor and

outdoors) with liquid soap. Bubbles indicate a leak. Be sure to wipe off the soap with a clean cloth.

If a CFC gas detector is used, use a special detector for HFC refrigerant (such as R410A and R134a).

12

(11) Replace the flare nut on the wide tube service port and fasten the flare nut securely with an adjustable wrench or

box wrench. Next, mount the valve cap and tighten it with a torque wrench (the cap needs to be tightened with the torque of 20 N·m (200 kgf · cm)). This process is very important to prevent gas from leaking from the system.

(12) Test run the air conditioner. (See page 18.)

(13) While the air conditioner is running, apply liquid soap to check for any gas leaks around the service valves or caps.

(14) If there is no leakage, stop the air conditioner.

(15) Wipe off the soap on the tubing.

This completes air purging with a vacuum pump and the air conditioner is ready for actual operation.

I Pump Down

In order to protect the earth’s environment, be sure to perform pump-down to recover refrigerant

gas without releasing it into the atmosphere.

G When relocating or disposing of the Air Conditioner, request

this service from the dealer where the unit was purchased, or from an appropriate agent. Perform pump-down as described below.

What is pump-down?

G Pump-down refers to recovering the refrigerant gas from the

refrigerant cycle at the outdoor unit. This work must be performed during cooling operation. The refrigerant gas cannot be recovered during heating operation.

G During winter, or if the temperature sensor prevents cooling

operation, perform “forced cooling operation.”

Pump-down procedure

(1) Fully close the spindles at the valves on the narrow tube

side of tubes A and B. (Refer to Fig. 22.)

(2) Connect the manifold gauge to the charging port at the valve

on the wide tube side of tube B. Purge the air from the charging hose. (Refer to Fig. 23.)

(3) Perform cooling operation or forced cooling operation.

When the pressure at the low-pressure side is 0.15 – 0.2 MPa (0.5 – 1 kg/cm

2

G), fully close the spindles at the valves on the wide tube side of tubes A and B, and immediately stop operation. (Refer to Fig. 23.) In the winter, the outdoor unit may stop after 5 – 10 minutes of operation. This is in order to protect the indoor unit heat exchanger from freezing and does not indicate a problem.

(4) Disconnect the manifold gauge and the inter-unit tubes,

and attach the caps and flare nuts. At this point, pumpdown is completed. (If the caps and flare nuts are not reattached, there is the danger of gas leakage.) (Refer to Fig. 24.)

5-1. General Precautions on Wiring

(1) Before wiring, confirm the rated voltage of the unit as

shown on its nameplate, then carry out the wiring closely following the wiring diagram.

(2) Provide a power outlet to be used exclusively for each

unit, with a power supply disconnect and circuit breaker for overcurrent protection provided in the exclusive

English

line.

(3) To prevent possible hazard due to insulation failure,

the unit must be grounded.

(4) Each wiring connection must be done tightly and in

accordance with the wiring system diagram. Wrong wiring may cause the unit to misoperate or become damaged.

(5) Do not allow wiring to touch the refrigerant tubing,

compressor, or any moving parts of the fan.

(6) Unauthorized changes in the internal wiring can be

very dangerous. The manufacturer will accept no responsibility for any damage or misoperation that occurs as a result of such unauthorized changes.

5-2. Recommended Wire Length and Diameter

Regulations on wiring diameter differ from locality to locality. For field wiring requirements, please refer to your local electrical codes. Carefully observe these regulations when carrying out the installation. Table 6 shows maximum wire lengths for control line and power line and fuse or circuit capacity.
