Piping Works And Flaring Technique

• Do not use contaminated or damaged copper tubing. If any pipings, evaporator or condenser had been exposed or had been opened for 15 seconds or more, the system must be vacuumed. Generally, do not remove plastic, rubber plugs and brass nuts from the valves, ﬁ ttings, tubings and coils until it is ready to connect suction or liquid line into valves or ﬁ ttings.

• If any brazing work is required, ensure that the nitrogen gas is passed through coil and joints while the brazing work is being done. This will eliminate soot formation on the inside walls of the copper tubings.

• Cut the pipe stage by stage, advancing the blade of the pipe cutter slowly. Extra force and deep cut will cause more distortion on the pipe and thus extra burr. See Figure A.

Cutting Copper Tube

Fig. B

Remove Burr

Fig. C

Copper Tube

Swaging Block

• Remove burrs from cut edges of the pipes with remover

as shown in Figure B. This will avoid unevenness on the ﬂ are faces which will cause gas leak. Hold the pipe on top position and burr remover at lower position to prevent metal chips from entering the pipe.

• Insert the ﬂ are nuts, mounted on the connection parts of

both the indoor unit and outdoor unit, into the copper pipes.

• The exact length of pipe protruding from the top surface of

the swaging block is determined by the ﬂ aring tool. Refer Figure C.

• Fix the pipe ﬁ rmly on the swaging block. Match the centers

of both the ﬂ are die and the ﬂ aring punch, and then tighten the ﬂ aring punch fully.

Piping Connection To The Units

• Align the center of the piping and tighten the ﬂ are nut

sufﬁ ciently with ﬁ ngers. Refer Figure D.

• Finally, tighten the ﬂ are nut with the torque wrench until

the wrench clicks.

• When tightening the ﬂ are nut with the torque wrench,

ensure that the tightening direction follows the arrow indicated on the wrench.

• The refrigerant pipe connection are insulated by closed

cell polyurethane.

Attach insulation sleeve

Round crimp-style terminal

Electric wire

Connect wires of the same gauge to both side.

Do not connect wires of the same gauge to one side.

Do not connect wires of different gauges.

• All wires must be ﬁ rmly connected.

• Make sure all the wire do not touch the refrigerant pipings, compressor or any moving parts.

• The connecting wire between the indoor unit and the outdoor unit must be clamped by using provided cord anchorage.

• The power supply cord must be equivalent to H07RN-F which is the minimum requirement.

• Make sure no external pressure is applied to the terminal connectors and wires.

• Make sure all the covers are properly ﬁ xed to avoid any gap.

• Use round crimp-style terminal for connecting wires to the power supply terminal block. Connect the wires by matching to the indication on terminal block. (Refer to the wiring diagram attached on the unit).

• Use the correct screwdriver for terminal screws tightening. Unsuitable screwdrivers can damage the screw head.

• Over tightening can damage the terminal screw.

• Do not connect wire of different gauge to same terminal.

• Keep wiring in an orderly manner. Prevent the wiring from obstructing other parts and the terminal box cover.

R410A is a new HFC refrigerant which does not damage the ozone layer. The working pressure of this new refrigerant is 1.6 times higher than conventional refrigerant (R22), thus proper installation / servicing is essential.

• Never use refrigerant other than R410A in an air conditioner which designed to operate with R410A.

• POE or PVE oil is used as lubricant for R410A compressor, which is different from the mineral oil used for R22 compressor. During installation or servicing, extra precaution must be taken not to expose the R410A system too long to moist air. Residual POE or PVE oil in the piping and components can absorb moisture from the air.

• To prevent mischarging, the diameter of the service port on the ﬂ are valve is different from that of R22.

• Use tools and materials exclusively for refrigerant R410A.

Tools exclusively for R410A are manifold valve, charging hose, pressure gauge, gas leak detector, ﬂ are tools, torque wrench, vacuum pump and refrigerant cylinder.

• As an R410A air conditioner incurs higher pressure

than R22 units, it is essential to choose the copper pipes correctly. Never use copper pipes thinner than 0.8mm even though they are available in the market.

• If the refrigerant gas leakage occurs during installation /

servicing, be sure to ventilate fully. If the refrigerant gas comes into contact with ﬁ re, a poisonous gas may occur.

• When installing or removing an air conditioner, do not

allow air or moisture to remain in the refrigerant cycle.

SPECIAL PRECAUTIONS WHEN DEALING WITH R410A UNIT

1-17

English

Vacuuming is necessary to eliminate all moisture and air from the system. The series II Outdoor Unit is provided with ﬂ are valve ﬁ ttings.

Vacuuming The Piping And The Indoor Unit

Except for the outdoor unit which is pre-charged with refrigerant, the indoor unit and the refrigerant connection pipes must be air-purged because the air containing moisture that remains in the refrigerant cycle may cause malfunction of the compressor.

• Remove the caps from the valve and the service port.

• Connect the center of the charging gauge to the vacuum

pump.

• Connect the charging gauge to the service port of the 3-way

valve.

• Start the vacuum pump. Evacuate for approximately 30

minutes. The evacuation time varies with different vacuum pump capacity. Conﬁ rm that the charging gauge needle has moved towards -760mmHg.

Caution

• If the gauge needle does not move to -760mmHg, be sure to

check for gas leaks (using the refrigerant detector) at ﬂ are type connection of the indoor and outdoor unit and repair the leak before proceeding to the next step.

• Close the valve of the changing gauge and stop the vacuum

pump.

• On the outdoor unit, open the suction valve (3 way) and

liquid valve (2 way) (in anti-clockwise direction) with 4mm key for hexagon sacked screw.

Charge Operation

This operation must be done by using a gas cylinder and a precise weighing machine. The additional charge is topped-up into the outdoor unit using the suction valve via the service port.

• Remove the service port cap.

• Connect the low pressure side of the charging gauge to the

suction service port center of the cylinder tank and close the high pressure side of the gauge. Purge the air from the service hose.

• Start the air conditioner unit.

• Open the gas cylinder and low pressure charging valve.

• When the required refrigerant quantity is pumped into

the unit, close the low pressure side and the gas cylinder valve.

• Disconnect the service hose from service port. Put back the

service port cap.

As shown in Figure above, it is recommended to move the unit by grabbing the left and right grip. Place your hands on the corner to avoid deforming of the casing.

Figure 1

A total of 4 direction options (refer ﬁ gure 2a) for connecting pipe (w, x, y, z) are available for your convenience. Cutting out the 2 slits with a metal saw make it possible to install as shown in Figures 2a. In order to make the connecting pipe in a downward direction (refer Figure 2b), make a knockout hole by drilling through the center area around the knockout hole. It is recommended to use a Ø6mm drill for this process (refer Figure 2c). After completing the knockout process, it is recommended to apply repair paint to the edge and surrounding surfaces to prevent rusting.

1. Handling

2. Refrigerant piping

Cover the pipe through-holes with insulation material to conceal all gaps to prevent small animals or insects from entering the outdoor unit which may result short circuit in the control box.

Figure 3

3. Caution for handling service port To be able to recover all remaining refrigerant at charge hose, always use a ﬂ exible charge hose with a push-rod and valve. After the work, tighten the valve cover in place with tightening torque: 11.5~13.9N.m

4. Charging refrigerant For cases where complete recharge of refrigerant is required, vacuuming via service part is mandatory, do not use stop valve port in this case because vacuuming through this stop valve port can not be executed completely. Outdoor units have 1 port on the piping. It is between the heat exchanger and the 4-way valve.

5. Pump-down operation Never by-pass the low pressure switch or low pressure sensor during pump down operation. Power supply must be cut off before pump-down operation. After opening the front panel, cover the PCB and terminal board with insulation sheet to avoid electric shock by accidental touching of LIVE parts. Do not leave the unit unattended if the front panel is open. Close the front panel before leaving the outdoor unit. Turn on the power supply and carry out pumping-down operation according to the steps written at front panel.

6. Electrical wiring work

BELOW INFORMATION IS APPLICABLE FOR 5SLY40/50FR ONLY

Figure 4

Secure the ground wire to the stop valve attachment plate (refer Figure 4) so that it does not slide. Ensure the front cover does not rise up after the wiring work is down. Close the front cover securely.

Figure 5

When cables are routed from the unit, a protection sleeve for the conduits can be inserted at the knock-out hole. It there is no wire conduit, do protect the wires with vinyl tubes to prevent cutting the wires by sharp edges of knock-out hole.
