∗Note 1
When the equivalent pipe length between outdoor and indoor
units is 90m or more, the size of main pipes (both gas-side and
liquid-side) must be increased.
Depending on the length of the piping, the capacity may drop, but
even in such case it is able to increase the size of main pipes.
(Refer to figure 9)

5. Indoor unit
∗Note 2
Allowable length after the first refrigerant branch kit to indoor units is 40 m or less, however it can be extended up to 90 m if all the following conditions are satisfied. (In case of “ Branch with REFNET joint ” )
∗Note 3
If the pipe size above the REFNET header is φ34.9 or more, KHRP26M73HP is required.

Required Conditions Example Drawings
1. It is necessary to increase the pipe size between the first branch kit and the final
branch kit. (Reducers must be procured on site)
However, the pipes that are same pipe size with main pipe must not be increased.
4. The difference between
[Outdoor unit to the farthest indoor unit] and [Outdoor unit to the nearest indoor unit]
≤ 40 m
2. For calculation of Total extension length, the actual length of above pipes must be
doubled. (except main pipe and the pipes that are not increased)

- A power circuit see the following table must be provided for con nection of the unit this circuit must be protected with the required safety devices i e a main switch a slow blow fuse on each phase and an earth leakage circuit breaker when using residual current operated circuit breakers be sure to use a high speed type 1 second or less 200ma rated residual operating current use copper conductors only use insulated wire for the power cord select the power supply cable type and size in accordance with relevant local and national regulations 14
- All field wiring and components must be installed by a licensed electrician and must comply with relevant local and national reg ulations be sure to use a dedicated power circuit never use a power sup ply shared by another appliance 14
- Caution 14
- English 14
- Ex combining the rxyq30ptlk e using rxyq8ptlk e rxyq10ptlk e and rxyq12ptlk e 14

- Note electrical wiring must be done in accordance with the wiring dia grams and the description herein do not operate until refrigerant piping work is completed if operated before complete the piping work the compressor may be broken down never remove thermistor sensor or etc when connecting power wiring and transmission wiring if operated with thermistor sensor or etc removed the compres sor may be broken down this product have reversed phase protection detector that only works when the power is turned on if there exists black out or the power goes on and off which the product is operating attach a reversed phase protection circuit locally running the product in reversed phase may break the compressor and other parts attach the power wire securely introducing power with a missing n phase or with a mistaken n phase will break the unit never connect the power supply in reversed phase the unit can not operate normally in reversed phase if you connect in reversed phase replace two of the 14
- Note make sure the weak electric wiring i e for the remote control ler between units etc and the power wiring do not pass near each other keeping them at least 50 mm apart proximity may cause electrical interference malfunctions and breakage be sure to connect the power wiring to the power wiring termi nal block and secure it as described in 7 5 power wiring connection procedure 14
- Note the above table indicates power specifications for standard combi nations see 2 introduction if using anything other than the above combinations in a multi sys tem calculate using the following procedure minimum circuit amp value add the minimum circuit amp values for each independent unit 14
- Only proceed with wiring work after blocking off all power always ground wires in accordance with relevant local and national regulations this machine includes an inverter device connect earth and leave charge to eliminate the impact on other devices by reducing noise generated from the inverter device and to prevent leaked current from being charged in the outer hull of the product do not connect the ground wire to gas pipes sewage pipes light ning rods or telephone ground wires gas pipes can explode or catch fire if there is a gas leak sewage pipes no grounding effect is possible if hard plastic pip ing is used telephone ground wires and lightning rods dangerous when struck by lightning due to abnormal rise in electrical potential in the grounding be sure to install an earth leakage circuit breaker this unit uses an inverter so install the earth leakage circuit breaker that be capable of handling high harmonics in order to prevent malfunctioning of the earth leakage circuit breaker i 14
