3.1 Power supply

External wiring procedure- The power supply work is needed only to the outdoor unit. The power supply to the BD unit and the indoor unit is conduct-

ed through the transmission wiring. Therefore, the power supply work can be carried out at just one place of the outdoorunit. It will contribute to simplify the work procedure and to save cost.

- Wiring cable size must comply with the applicable local and national code.

2. Heating Capacity is based on : indoor temp.20°C DB; outdoor temp. 7°C DB, 6°C WB

3. The rated capacities above show the rise in the total indoor unit capacity when operating frequency is constant. Values for changes in capacity are fixed after accounting for variations in operating frequency and should be used as reference values.

4. Total capacity index of indoor unit should be within 16~46 Btu/h(40%~130%)

5. At least two indoor units should be connected.

3) Calculation of actual system capacity① Outdoor unit rated capacity

Qodu(rated) [from specification table]

② Outdoor unit capacity at Ti, To temperature.Qodu(Ti, To) [from capacity table]

③ Outdoor unit capacity coefficient factorF(Ti, To) = Qodu(Ti, To) / Qodu(rated)

④ Piping correction factor [from capacity voefficient factor table]Fmain (length, elevation) for main piping length or elevationFbranch (length, elevation) for branch piping length or elevation

⑤ Individual indoor unit combinational capacityQidu (combi) = Qodu(rated) x Qidu(rated) / Qidu(rated-total)

⑥ Individual indoor unit actual capacityQidu (actual) = Qodu(combi) x F(Ti, To) x Fmain (length, elevation) x Fbranch (length, elevation)

Example) • Outdoor unit model : A7UW428FA3 [FM41AH U33]• Total indoor units combination : 7k(A room) + 7k .... + 9k• Outdoor temperature : 39°CDB• Indoor temperature : 19.5°CWB (A room)• Main piping length (O/D to BD) : 40m• Branch piping length (BD to I/D) : 10m (A room)• Indoor unit actual coding capacity in A room?

- Qodu (rated) : 11.7 kW- Qodu (Ti, To) :

1) Combination ratio : Qodu (rated - total) / Qodu (rated) = 115%2) From capacity table at Ti, To

110% : 11.4 kW120% : 11.4 kW∴ Qodu (Ti, To) = 115%

- F(Ti, To) : 11.4 kW / 11.7 kW = 97%- Fmain (length, elevation) = 89.8% (40m)- Fbranch (length, elevation) = 96.0% (7k, 10m)

- Qidu(combi) [7k] = 40k x ––––– = 6.1 k Btu/h

∴Qidu(actual) [7k] = 6.1k x 0.97 x 0.898 x 0.96= 5.05 k Btu/h

3.11 Electrical characteristics

Notes :1. Voltage range

Voltage supplied to the unit terminals should be within the mini-mum and maximum range

2. Maximum allowable voltage unbalance between phase is 2 %

3. MCA / MOPMCA = (1.25 x RLA) + Load1 + Load2MOP = (2.25 x RLA) + Load1 + Load2- Load1 : sum of current for all other motors- Load2 : any other load rated 1.0A or more

4. Select wire spec. based on the MCA

5. Select proper circuit breaker as given below MCA < Circuit breaker ≤ MOP

6. Recommended circuit breaker is ELCB (Earth Leakage circuitbreaker)

7. MSC & RLA are measured as the compressor only test condi-tion.

8. MSC values

9. RLA is measured during each individual compressor test condi-tion.Ex) 5.0 : RLA of (inv. comp.)

10. OFM is measured as the outdoor unit test condition

(Example) Selection of proper circuit breaker

① Model : A7UW428FA3[FM41AH U33]② MCA = (1.25 x RLA) + Load1 + Load2

= (1.25 x 6.1) + 0 + (0.73 x 2) = 9.09 A

③ MOP = (2.25 x RLA) + Load1 + Load2= (2.25 x 6.1) + 0 + (0.73 x 2) = 15.19 A→ Finally select circuit breaker 20A

MCA : Minimum Circuit Amperes (A)

MOP : Maximum rating over current protective device

MSC : Maximum Starting Current

RLA : Rated Load Amperes (A)

OFM : Outdoor Fan Motor

kW : Fan Motor rated output (kW)

4.8.2 Refrigerant chargeThe calculation of the additional charge should be taken into account for the additional length of pipe.

■ (1Ø)Additional charge (g) = ((A Room Installation Length – Standard Length ) x 20g/m

+ (B Room Installation Length – Standard Length ) x 20g/m +.. )- CF(Correction Factor) x 150

❈ CF = Max. number of connectable indoor unit – Total number of connected indoor unit

■ (1Ø , 3Ø) Additional charge (g) = (( Total Main piping Length - Main Standard Length ) x 50g/m

+ (A Room Branch Length – Standard Length ) x 20g/m + (B Room Branch Length – Standard Length ) x 20g/m+ (C Room Branch Length – Standard Length ) x 20g/m +.. ) - CF(Correction Factor) x 100

❈ CF = Max. number of connectable indoor unit – Total number of connected indoor unit

If the total additional charge value after calculation comes out to be negative, then do not consider additional charge.

NOTE

Long pipe setting

1) Open the top cover of outdoor unit.

2) Select one of the two selectable modes as follows.• If total additional charge value after calculation

comes out to be positive, move the slide switch to"LONG" position.

3) Close the top cover and check whether the productworks normally.

• There is no limitation on the joint mounting configuration.

• If the diameter of the refrigerant piping selected by the procedures described is different from the sizeof the joint, the connecting section should be cut with a pipe cutter.

• Branch pipe should be insulated with the insulation in each kit.

• Ensure that the branch pipes are attached horizontally or vertically (see the diagram below.)Facing upwards

Thermal insulation work

• Securely wrap the refrigerant and the branch pipe by using thermal insulation materials provided.When using thermal insulation materials released, use withstand heat insulation materials.(thicknessof more than 10mm)

• Securely adhere thermal insulation materials wrapping the branch pipe so that they do not widen. After wrapping them with auxiliary materials , bound them with a band .

• Finish the work by wrapping with a vinyl tape after the insulation material work.

• When installing the branch pipe, direction and angle of installation is not limited.• Take care so that burrs and foreign material may not enter into the cutting surface when connecting.

1. The maimum height between any two BD units or any tow indoor units should be 10m.Set up the BD unit and indoor unit within 15m.

2. The piping connection must suit the piping sizes of the indoor unit which will be connected. (If need, use the connector which is included in the indoor unit)

3. The BD unit should be installed inside the building.

4. Wiring cable size must comply with the applicable local and national code.

NOTE




3) Installation of BD unit

① Branch distributor unit We recommend BD unit installation at indoor side. but, ifyou install it outdoor side, care should be taken againstwater and other factors which may damage the pcb.

③ Installation of BD unit• This unit may be installed suspended from the ceiling or

mounted on the wall.

• This unit may only be installed horizontally , as shown inthe diagram below. (Side B is facing up) However, it maybe freely installed in any direction, forward or backward,and to the sides.

• Be sure to secure a 600mm square opening for serviceand inspection as shown in the diagram below, for bothceiling - suspended installation and wall-mounted installa-tion.

• BD unit does not require drain treatment as it uses inter-nal insulation.

• Service direction is the side B and C

• The piping for the indoor unit may be led around in direc-tion A

• The inclination of side B must be within ±5 degree for-ward or backward or to the sides.

Available condition

Temp : Max. 54

Humidity : Max.80% PCB

② Connection of piping (flare work)• No brazing & easy installation

• Be sure to mark all the local refrigerant piping(liquidpipes, gas pipes, etc.) for each indoor unit designatingclearly to which room it belongs to. (A, B, C, D)

④ Connection of piping

• When connecting indoor units, make sure to connect refrigerant pipes and connection wires to the appropriate connection portsmaked with matching alphabets. (A, B, C, D)

• Be sure to mark all the local refrigerant piping(liquid pipes, gas pipes,etc.) for each indoor unit designating clearly which room it belongs in.(A, B, C, D)

NOTE

For flaring work the piping, follow the instructions in the installation manual to each unit.

a) Align the center of the pipings and sufficiently tight-en the flare nut by hand.

b) Tighten the flare nut with a wrench.

c) Wrap the insulation material around the connect-ing portion.

① Overlap the Refrigarant cable insulation material and theindoor unit pipe insulation material. Bind them togetherwith vinyl tape so that there is no gap.

②Wrap the area which accommodates the rear pipinghousing section with vinyl tape.

③ Align the center of the piping and sufficiently tighten thebrass cap by hand.

④ Tighten the brass cap with a wrench.

⑤Wrap the joint part with insulation.
