2.2 Product character

2.2.1 Phylogeny

E-Multi(R410A) series is multi split ON/OFF type series, developed based on Free Multi (R407C).

2.2.2 Operating individually and operating simultaneously

The unit can realize individual operation which can control one unit running, stop, and adjusting running mode. Also the unit can operate simultaneously which control multi indoor units at same time.

2.2.3 Variable quantity of indoor unit

If you want to add or reduce the quantity of indoor units (of course the match must correspond with the design), it can meet your need at any time. More convenient, more random.

2.2.4 Universal outdoor unit, multiform indoor unit

We realize universal outdoor unit, and 6 kinds of indoor unit, choose freely according to customer indoor decoration, more stylish and more beautiful

2.2.5 The total capacity of indoor unit can be more than that of outdoor unit.

When all the indoor units are running at the same time, the actual capacity of every indoor unit is proportional according to outdoor capacity.

2.2.6 Long distribution pipe and high drop

The distance of outdoor and indoor can be max. 15m, and the drop between indoor and outdoor can be max. up to 5m, consequently, the installation can be more free, and can meet various need of the customer.

2.2.7 Duct type unit be equipped with high efficiency filter, and its high static pressure can be up to 30Pa, running more silent, making room air more comfortable and more clean.

2.2.8 Auto-check function

The unit can display the malfunction codes on the control board by using advanced auto-check technology ,convenient for user find and dwell with the abnormal running.

2.2.9 Auto

restart function (optional )

All indoor units have auto-restart function. When the power supply cut off suddenly, the unit will automatically recover the previous running mode once the power supply is on

s favor and

Communication Wire connection:

1. The indoor unit whose liquid pipe is connected to A1 in A system is called unit A1, its communication wire of A1(3)、 A1(4) should be connected to A1(P)、A1(Q) respectively.

2. The indoor unit whose liquid pipe is connected to A2 in A system is called unit A2, its communication wire of A2(3) 、A2(4) should be connected to A2(P)、A2(Q) respectively.

3. The indoor unit whose liquid pipe is connected to B1 in B system is called unit B1, its communication wire of B1(3) 、B1(4) should be connected to B1(P)、B1(Q) respectively.

4. The indoor unit whose liquid pipe is connected to B2 in B system is called unit B2, its communication wire of B2(3) 、B2(4) should be connected to B2(P)、B2(Q) respectively.

Note: Because the customers themselves matcTh the communication wire, and the P and Q are nonpolar, the customers must use shielded communication wires.

Note: Though AU422XIEAA can match with the R407C free multi indoor unit, we do not

recommend so. Because that will not only lower the capacity,also the changing pipe 0010759292 will be required for all R407C free multi indoor unit when installation.

3. Outdoor wiring diagram should be changed as the following:

Coil of solenoid vavle A2 should be changed to connected with CN29.

Coil of solenoid vavle B2 should be changed to connected with CN23.

By-pass vavle on both system A and system B should be pulled out and not connected.

8. Installation Procedure

8.1.1. Selection of Installation Place (For AB072-142XCEAA)

(1) Place above the ceiling where it is enough space to arrange the unit. (2) Place where the drainage pipe can be arranged well. (3) Place where inlet and outlet air of indoor and outdoor unit will not be blocked.

(4) Do not expose the unit to the place with heavy oil or moisture (e.g.kitchen and workshop). (5) Do not set the unit in the place where destructive gas (such as sulfuric acid gas) or pungent

gas (thinner and gasoline) concentrates and retains.

(6) Place strong enough to support the unit . (7) No expensive articles such as television and piano below indoor unit.

(8) Enough space for maintenance. (9) Place more than 1m away from television and radio to avoid disturbing television and radio. (10) Easy for maintenance.

Power supply wire parameters: H05RN-f 3G(0.75~1.5)mm Signal wire parameters: H05RN-F 2x0.75mm The signal wire must be shielded wire.

Wiring methods:

1.Wiring method of ring terminal

For connecting line which end is a ring,its wiring method as shown in the right figure: remove wiring screw and pass it through the end ring of connecting line,then connect it to the terminal block and tighten screw.

2. Wiring method of straight terminal

For connecting line which end is not a ring, its wiring method as follows: loosen wiring screw ans insert the end of connecting line totally into the terminal block,then tighten the screw and pull the connecting line slightly to confirm that it is clamped firmly.

In case of no ceiling

Install unit temporarily

Put suspending bracket on the suspending bolt to hang the unit up. Be sure to use nut and washer at both end of the breaket to secure firmly.

After installation on the ceiling

(1) Adjust unit to its right position (Refer to preparation for installation-(1)) (2)Check that unit is horizontal.

Water pump and floating switch is installed inside indoor unit,check four corners of the unit for its lever using horizontal comparator or PVC tube with water.(If unit is tilting against the direction of water drainage,problem may occur on floating water leakage.)

Pipe diameter shall be equal or larger than that of connecting pipe (Pipe of polythene; size: 25mm; O.D.: 32mm )

Drainpipe should be short, with a downward slope at least 1/100 to prevent air bag from forming.

If downward slope of drainpipe cannot be made,lifting pipe shall be installed. Keep a distance of 1-1.5m between suspending bolts, to make water hose straight.
