INSTALLATION INSTRUCTIONS
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
unit
1. Do not remove the plastic seals from the indoor
equiopment 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 essential
that you read the following instructions carefully.
3. Hold the points marked A using a 22mm/0.87in open-
ended spanner and turn the nuts only at the points
marked B using a 24mm/0.95in open-ended spanner.
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 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 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 reason, the quick connector parts
are recommended to be placed outside of room.

Do not smoke during the installation work.
The equipment must never be operated without
the refrigerant lines connected, otherwise the
equipment will be damaged immediately.
The screw connections may only be tightened
using the appropriate open-ended spanner.
