SAFETY PRECAUTION

3-1. ALWAYS OBSERVE FOR SAFETY

Before obtaining access to terminal, all supply circuits must be disconnected.

3-2. CAUTIONS RELATED TO NEW REFRIGERANT

Cautions for units utilizing refrigerant R410A

Use new refrigerant pipes.

In case of using the existing pipes for R22, be careful with the followings.

· Be sure to perform replacement operation before test run.

· Change flare nut to the one provided with this product. Use a newly flared pipe.

· Avoid using thin pipes.

Make sure that the inside and outside of refrigerant piping is clean and it has no contamination such as sulfur hazardous for use, oxides, dirt, shaving particles, etc. In addition, use pipes with specified thickness.

Contamination inside refrigerant piping can cause deterioration of refrigerant oil etc.

Store the piping to be used during installation indoors and keep both ends of the piping sealed until just before brazing. (Leave elbow joints, etc. in their packaging.)

If dirt, dust or moisture enters into refrigerant cycle, that can cause deterioration of refrigerant oil or malfunction of compressor.

Use ester oil, ether oil or alkylbenzene oil (small amount) as the refrigerant oil applied to flares and flange connections.

If large amount of mineral oil enters, that can cause deterioration of refrigerant oil etc.

Do not use refrigerant other than R410A.

If other refrigerant (R22 etc.) is used, chlorine in refrigerant can cause deterioration of refrigerant oil etc.

Use a vacuum pump with a reverse flow check valve.

Vacuum pump oil may flow back into refrigerant cycle and that can cause deterioration of refrigerant oil etc.

Use the following tools specifically designed for use with R410A refrigerant.

The following tools are necessary to use R410A refrigerant.

Tools for R410A Gauge manifold Charge hose

Gas leak detector

Torque wrench

Flare tool Size adjustment gauge

Vacuum pump adaptor Electronic refrigerant charging scale

Keep the tools with care.

If dirt, dust or moisture enters into refrigerant cycle, that can cause deterioration of refrigerant oil or malfunction of compressor.

Do not use a charging cylinder.

If a charging cylinder is used, the composition of refrigerant will change and the efficiency will be lowered.

Charge refrigerant from liquid phase of gas cylinder.

If the refrigerant is charged from gas phase, composition change may occur in refrigerant and the efficiency will be lowered.

Ventilate the room if refrigerant leaks during operation. If refrigerant comes into contact with a flame, poisonous gases will be released.

[1] Cautions for service

(1) Perform service after recovering the refrigerant left in unit completely. (2) Do not release refrigerant in the air. (3) After completing service, charge the cycle with specified amount of refrigerant. (4) When performing service, install a filter drier simultaneously. Be sure to use a filter drier for new refrigerant.

[2] Additional refrigerant charge

When charging directly from cylinder

· Check that cylinder for R410A on the market is syphon type.

· Charging should be performed with the cylinder of syphon stood vertically. (Refrigerant is charged from liquid phase.)

3-3. PRECAUTIONS WHEN REUSING EXISTING R22 REFRIGERANT PIPES

(1) Flowchart

Measure the existing pipe thickness and check for damage.

The existing pipe thickness meets specifications and the pipes are not damaged.

Check if existing air conditioner can operate.

Existing air conditioner can operate.

Perform cooling operation for about 30 minutes and then do a pump down work.

Disconnect existing air conditioner from piping.

Existing pipes can be reused.

Existing air conditioner cannot operate.

Use a refrigerant recovery equipment to recover the refrigerant.

In case existing pipes were used

+

for gas or oil heat pump system, be sure to clean the pipes for HRP71,100,125 models.

The existing pipe thickness does not meet specifications or the pipes are damaged.

Existing pipes cannot be reused. Use new pipes.

In case the unit is RP35/50 or RP60/71VHA2(1) which utilizes HAB oil.

In case the unit is HRP71, 100, 125 which utilize ester oil or ether oil.

Connect a new air conditioner.

Perform replacement operation.

·When performing replacement operation, make sure that DIP SW8-2 on outdoor unit controller board is set to ON. +Chemical compounds containing chlorine left in existing pipes are collected by replace filter.

●The air conditioner automatically performs cooling operation through replace filter for about 2 hours.

Connecting a new air conditioner

Flaring work should be done so that flare meets the dimension for R410A. Use flare nut provided with indoor and outdoor unit.

When using gas piping of :19.05mm for HRP100, 125. Make sure that DIP SW8-1 on outdoor unit controller board is set to ON.

This is to keep the pressure on pipes within permissible range.

●Use different diameter joint or adjust the piping size by brazing. When using pipes larger than specified size for HRP71.

Make sure that DIP SW8-1 on outdoor unit controller board is set to ON.

This is to prevent oil flow ratio from lowering due to the decrease in flowing refrigerant.



●Use different diameter joint or adjust the piping size by brazing. When existing pipes are specified size.

The pipes can be reused referring to TECHNICAL DATA BOOK (OCS11).

●Use different diameter joint or adjust the piping size by brazing.

* When using existing pipes for HRP71, 100, 125 Make sure that DIP SW8-2 on outdoor unit controller board is set to ON and perform replacement operation.

+Chemical compounds containing chlorine left in existing pipes are collected by replace filter.

●The air conditioner automatically performs cooling operation through replace filter for about 2 hours.

(2) Cautions for refrigerant piping work

New refrigerant R410A is adopted for replacement inverter series. Although the refrigerant piping work for R410A is same

as for R22, exclusive tools are necessary so as not to mix with different kind of refrigerant. Furthermore as the working pressure of R410A is 1.6 time higher than that of R22, their sizes of flared sections and flare nuts are different.

1Thickness of pipes Because the working pressure of R410A is higher compared to R22, be sure to use refrigerant piping with thickness

shown below. (Never use pipes of 0.7mm or below.)

2Dimensions of flare cutting and flare nut The component molecules in HFC refrigerant are smaller compared to conventional refrigerants. In addition to that, R410A is a refrigerant, which has higher risk of leakage because its working pressure is higher than that of other refriger ants. Therefore, to enhance airtightness and intensity, flare cutting dimension of copper pipe for R410A have been speci fied separately from the dimensions for other refrigerants as shown below. The dimension B of flare nut for R410A also has partly been changed to increase intensity as shown below. Set copper pipe correctly referring to copper pipe flaring dimensions for R410A below. For 1/2 and 5/8 inch, the dimension B changes. Use torque wrench corresponding to each dimension.

9-4. M-NET WIRING METHOD

(Points to notice) (1) Outside the unit, transmission wires should stay away from electric wires in order to prevent electromagnetic noise from

making an influence on the signal communication. Place them at intervals of more than 5cm. Do not put them in the same

conduit tube. (2) Terminal block (TB7) for transmission wires should never be connected to 220~240V power supply. If it is connected, electronic parts on M-NET P.C. board may burn out. (3) Use 2-core x 1.25mm2 shield wire (CVVS, CPEVS) for the transmission wire. Transmission signals may not be sent or

received normally if different types of transmission wires are put together in the same multi-conductor cable. Never do this

because this may cause a malfunction.

Group remote controller

It would be ok if M-NET wire (non-polar, 2-cores) is arranged in addition to the wiring for A-control.

(4) Ground only one of any appliances through M-NET transmission wire (shield wire). Communication error may occur due to

the influence of electromagnetic noise. “Ed” error will appear on the LED display of outdoor unit. “0403” error will appear on the central-control remote controller.

Good example 2 (Single spot grounding of shield wire)

Central remote controller

M-NET transmission wire

If there are more than 2 grounding spots on the shield wire, noise may enter into the shield wire because the ground wire

and shield wire form one circuit and the electric potential difference occurs due to the impedance difference among ground-

ing spots. In case of single spot grounding, noise does not enter into the shield wire because the ground wire and shield

wire do not form one circuit. To avoid communication errors caused by noise, make sure to observe the single spot grounding method described in the

installation manual.

(1) Use 2-core x 1.25mm

shield wire for electric wires. (Excluding the case connecting to system controller.) (2) Connect the wire to the M-NET terminal block. Connect one core of the transmission wire (non-polar) to A(M1) terminal and the other to B(M2). Peel the shield wire, twist the shield part to a string and connect it to S terminal. (3) In the system which several outdoor units are being connected, the terminal (A(M1), B(M2), S) on M-NET terminal block should be individually wired to the other

and drive a screw to fix an ground wire on the plate as shown on the right figure.

9-4-1. M-NET address setting

In A-control models, M-NET address and refrigerant address should be set only for the outdoor unit. Similar to CITY MULTI system, there is no need to set the address of outdoor unit and remote controller. To construct a central control system, the setting of M-NET address should be conducted only upon the outdoor unit. The setting range should be 1 to 50 (the same as that of the indoor unit in CITY MULTI system), and the address number should be consecutively set in a same group.

Address number can be set by using rotary switches (SW11 for ones digit and SW12 for tens digit), which is located on the M-NET board of outdoor unit. (Initial setting: all addresses are set to “0”.)

9-4-2. Refrigerant address setting

In case of multiple grouping system (multiple refrigerant circuits in one group), indoor units should be connected by remote controller wiring (TB5) and the refrigerant address needs to be set. Leave the refrigerant addresses to “00” if the group setting is not conducted. Set the refrigerant address by using DIP SW1-3 to -6 on the outdoor controller board. [Initial setting: all switches are OFF. (All refrigerant addresses are “00”.)]

10-1. Refrigerant recovering (pump down)

Perform the following procedures to recover the refrigerant when moving the indoor unit or the outdoor unit. 1Turn on the power supply (circuit breaker). wWhen power is supplied, make sure that “CENTRALLY CONTROLLED” is not displayed on the remote controller. If

“CENTRALLY CONTROLLED” is displayed, the refrigerant recovering (pump down) cannot be completed normally.

2After the liquid stop valve is closed, set the SWP switch on the control board of the outdoor unit to ON. The compressor

(outdoor unit) and fans (indoor and outdoor units) start operating and refrigerant recovering operation begins. LED1 and LED2 on the control board of the outdoor unit are lit.

wSet the SWP switch (push-button type) to ON in order to perform refrigerant recovering operation only when the unit is

stopped. However, refrigerant recovering operation cannot be performed until compressor stops even if the unit is stopped.

Wait 3 minutes until compressor stops and set the SWP switch to ON again.

3Because the unit automatically stops in about 2 to 3 minutes after the refrigerant recovering operation (LED1 is not lit and

LED2 is lit), be sure to quickly close the gas stop valve. w In case the outdoor unit is stopped when LED1 is lit and LED2 is not lit, open the liquid stop valve completely, and then

repeat step 2 3 minutes later.

w If the refrigerant collecting operation has been completed normally (LED1 is not lit and LED2 is lit), the unit will remain

stopped until the power supply is turned off.

4Turn off the power supply (circuit breaker).

10-2. Unit replacement operation

When reusing the existing pipes that carried R22 refrigerant for the HRP71, HRP100 and HRP125 models, replacement operation must be performed before performing a test run.

1If new pipes are used, these procedures are not necessary. 2During replacement operation, “C5” is displayed on “A-Control Service Tool(PAC-SK52ST)”.

Replacement operation procedures

1Turn on the power supply. 2Set DIP switch SW8-2 on the control board of the outdoor unit to ON to start replacement operation.

• The replacement operation is performed using the cooling system. Cool air will flow from the indoor unit during the replacement operation.

• During the replacement operation, control board of the outdoor unit blink together.

3Replacement operation requires at least 2 hours to complete.

• After setting switch SW8-2 to ON, the unit automatically stops after 2 hours.

• Replacement operation can be performed repeatedly by setting switch SW8-2 from OFF to ON. Make sure to perform

the operation more than 2 hours. (If the operation is performed less than 2 hours, the existing pipes cannot be cleaned enough and the unit may be damaged.)

• If replacement operation is performed over 2 hours, this action is recorded into nonvolatile memory of control board.

4Set switch SW8-2 to OFF. (Replacement operation is completed.)

wThe unit can be operated normally by remote controller even if SW8-2 remains ON. wIf the indoor temperature is less than 15:, the compressor will operate intermittently but the unit is not faulty.

10-3. Start and finish of test run

• Operation from the indoor unit

Execute the test run using the installation manual for the indoor unit.

• Operation from the outdoor unit By using the DIP switch SW4 on the control board of outdoor unit, test run can be started and finished, and its operation mode (cooling/heating) can be set up.

1Set the operation mode (cooling/heating) using SW4-2. 2Turn on SW4-1 to start test run with the operation mode set by SW4-2. 3Turn off SW4-1 to finish the test run.

• There may be a faint knocking sound around the machine room after power is supplied, but this is no problem with product because the linear expansion pipe is just moving to adjust opening pulse.

• There may be a knocking sound around the machine room for several seconds after compressor starts operating, but this is no problem with product because the check valve itself generates the sound because pressure difference is small in the refrigerant circuit.

11-2. CHECK POINT UNDER TEST RUN

(1) Before test run

• After installation of indoor and outdoor units, piping work and electric wiring work, re-check that there is no refrigerant leak-

age, loosened connections and incorrect polarity.

• Measure impedance between the ground and the power supply terminal block (L, N) on the outdoor unit by 500V Megger and check that it is 1.0M" or over.

wDon’t use 500V Megger to indoor/outdoor connecting wire terminal block (S1, S2, S3) and remote controller terminal block (1, 2). This may cause malfunction.

• Make sure that test run switch (SW4) is set to OFF before turning on power supply.

• Turn on power supply 12 hours before test run in order to protect compressor.

• For specific models which requires higher ceiling settings or power failure automatic recovery, make proper changes of set-

tings referring to the description of “Selection of Functions through Remote Controller”.

Make sure to read operation manual before test run. (Especially items to secure safety.)

Check for correct motion of auto-vanes.

The outdoor unit features automatic capacity control to provide optimum fan speeds. Therefore, the fan keeps running at a low speed to meet the current outside air condition unless it exceeds its available maximum power. Then, in actuality, the fan may stop or run in the reverse direction depending on the outside air, but this does not mean malfunction.

Check if cool air blows and water is drained.
