Remember that if they are tightened with too little torque they will leak but if they are tightened with too much torque, the screw connections may suffer damage. If you should not be confident about connecting the refrigerant line connectors yourself, it is imperative that you contact your customer service team or a refrigeration contractor.Important! The EQ valves are only designed for one-time installation. Their seal can not be guaranteed if they are installed on more than one occasion. This will also void the warranty.

4.3 Connecting the refrigerant pipes to indoor unit1. Do not remove the plastic seals from the indoor equipment and the appropriate refrigerant pipe until immediately before you connect them.2. Align the refrigerant pipes correctly, make sure the dimensions of the connecting refrigerant pipe are the same. Place the screw connector on the refrigerant pipes just on to the thread on the indoor equipment and tighten the first few threads by hand. See Fig.9.IMPORTANT: Before you continue, it is essentialthat you read the following instructions carefully.

3. Hold the points marked A using a 22mm/0.87in open- ended wrench and turn the nuts only at the points marked B using a 24mm/0.95in open-ended wrench. See Fig.10a & 10b.4. Ensure that the screw connectors do not skew as you tighten them and work quickly.

IMPORTANT: Since the coupling works with tappingrings, it may leak if you undo and reconnect the pipes. This will also void the warranty.

5. After finishing the connection, first wrap up the quick connectors with the sound deadening pads(packed with accessories) solidly and tightly as shown in Fig.11, then use the tape to wrap the refrigerant pipe and connecting cable together. See Fig.12.

NOTE: For aesthetic reasons, the quick connector parts are recommended to be placed outside of room.

1. Run the drain hose sloping downward. Do not install the drain hose as illustrated in Fig.7.

2. When connecting extension drain hose, insulatethe connecting part of extension drain hose witha shield pipe, do not let the drain hose slack.

4. Connecting the refrigerant pipes

4.1 Too ls needed -You will require the following tools to carry out thisinstallation work correctly:

1 x open-ended wrench, 19 mm/0. 75in1 x open-ended wrench, 22 mm/0.87in1 x open-ended wrench, 24 mm/0.95in1xAllen key, 5 mm/0.2in1 x Philips screwdriver1 x leak detection spray or alternatively soap suds(water/detergent mix)

4.2 Important information• Follow the detailed instructions for connecting

the refrigerant pipes to the indoor unit andoutdoor unit. We can only provide a warranty ifthe lines are installed correctly as described inthe instructions.

• Do no t remove the sealing caps and stoppersunti l immedi ately before you install the lines.

• To prevent leaks, ensure that the quick-releasescrew connections are absolutely free of dirt.Moisture or foreign bodies will adversely affectthe function of the quick-release connectors,leading to a risk of refrigerant loss (not coveredby the warranty).

• Only install refrigerant lines outdoors in dryweather.

• The refrigerant lines must not be installed andthen plastered over.

• Please make sure that refrigerant is never

allowed to enter the environment.

Improper handling of refrigerant may be harmfulto health. Always wear work gloves and goggleswhen handling refrigerant.

NOTE: To distinguish the connectors to be connected to the indoor unit and outdoor unit, the connectors of the refrigerant pipe has been labelled "A" ,

"B" , "C" and "D" . Ensure the marks on the connectors are the same to the indoor's and outdoor's respectively during connection.



• Do not smoke during the installation work.The equipment must never be operated withoutthe refrigerant lines connected, otherwise theequipment will be damaged immediately.

• The screw connections may only be tightenedusing the appropriate open-ended wrench.

• Remember that if they are tightened with toolittle torque they will leak but if they are tightenedwith too much torque, the screw connections maysuffer damage. If you should not be confidentabout connecting the refrigerant line connectorsyourself, it is imperative that you contact yourcustomer service team or a refrigeration contractor.

Important! The EQ valves are only designed for

one-time installation. Their seal can not be

guaranteed if they are installed on more than one

occasion. This will also void the warranty.

4.3 Connecting the refrigerant pipes to indoor unit

1. Do not remove the plastic seals from the indoorequipment and the appropriate refrigerant pipeuntil immediately before you connect them.

2. Align the refrigerant pipes correctly, make surethe dimensions of the connecting refrigerant pipeare the same. Place the screw connector on therefrigerant pipes just on to the thread on theindoor equipment and tighten the first few threadsby hand. See Fig.9.

IMPORTANT: Before you continue, it is essential that you read the following instructions carefully.

3. Hold the points marked ':A."using a 22mm/0.87in openended wrench and turn the nuts only at the pointsmarked "B"using a 24mm/0.95in open-ended wrench.See Fig.1 Oa & 1 Ob.

4. Ensure that the screw connectors do not skew asyou tighten them and work quickly.

IMPORTANT: Since the coupling works with tapping rings, it may leak if you undo and reconnect the pipes. This will also void the warranty.

5. After finishing the connection, first wrap up the quickconnectors with the sound deadening pads(packed withaccessories) solidly and tightly as shown in Fig.11,

then use the tape to wrap the refrigerant pipe andconnecting cable together. See Fig.12.

Note: Route the package of pipes/hoses in the direction of (rear)right or (rear)left. See Fig.13.

One side drainage structure is standard. Both sides drainage structure is optional and can only be customized from factory.For both sides drainage structure, it can be choosen for right, left or both sides drainage connection. If choosing both sides drainage connection, another proper drain hose is needed as there is only one drain hose offered by factory. If choosing one side drainage connection, make sure the drain hole on the other side is well plugged. For 9k/12k models, if choosing right side drainage connection, please choosing right-hand or right-back piping.The connection of the drain hose is supposed to be done by qualified installer in case of water leakage. 5. Bundle the tubing, connecting cable with tape

securely, evenly as shown in Fig.14.

• Because the condensed water from rear of theindoor unit is gathered in ponding box and ispiped out of room. Do not put any thing else inthe box.

CAUTION:

• Do not allow the piping to let out from the back ofthe indoor unit.

• Be careful not to let the drain hose slack.

• Heat insulate both of the auxiliary piping.• Be sure that the drain hose is located at the

lowest side of the bundle. Locating at the upperside can cause drain pan to overflow inside theunit.

• Never intercross nor intertwist the power wirewith any other wiring.

• Run the drain hose sloped downward to drain

out the condensed water smoothly.

5. Indoor unit installation1. Feed the package of pipes/hoses through the hole

in the wall.2. Hook the indoor unit onto the upper portion of the

installation plate.(Engage the two hooks of the reartop of the indoor unit with the upper edge of theinstallation plate.) Ensure that the hooks areproperly seated on the installation plate by movingit left and right.

After completing steps 1- 4, check that all the connections are sealed correctly using leak detection spray or soap suds. If any bubbles form,the system has a leak and the screw connectors must be retightened using an open-ended wrench.

5. Now remove the cover on the top valve using a 19 mm open-ended wrench. Open the valve by turning it counter-clockwise as far as it will go using a 5 mm Allen key. The valve is now open. If the valve is not opened fully, the system may malfunction and suffer damage. Screw the cover back on to the top valve and tighten it well to ensure that it is properly sealed. See Fig.24.

6. Now remove the cover on the bottom valve using a 19 mm open-ended wrench. Open the valve by turning it counter-clockwise as far as it will go using a 5 mm Allen key. The valve is now open. If the valve is not opened fully, the system may malfunction and suffer damage. Screw the cover back on to the bottom valve and tighten it well to ensure that it is properly sealed. See Fig.25.

Important! The conical ring on the valve has an important sealing function together with the sealingseat in the caps. Ensure that you do not damage thecone and that you keep the cap free of dirt and dust.

7. After completing steps 1- 6, check that all the connections are sealed correctly using leak detection spray or soap suds. If any bubbles form, the system has a leak and the screw connectors must be retightened using an open- ended spanner.

8. Start the equipment so that the operating pressures build up inside it. Check all the connectors again for signs of leaks a) during cooling mode b) in heating mode. If any bubbles form, the system has a leak and the screw connectors must be retightened using an open-ended wrench.
