Installation Manual

1. First remove the water tray on the outdoor unit

as shown in Fig.20.

2. Do not remove the plastic seals from the outdoor

unit and the appropriate refrigerant pipes until

immediately before you connect them, Fig.21.

3. Align the refrigerant pipes correctly so that they

line up with the valves and are not stressed.

Place the screw connector on the refrigerant line

just on to the thread on the outdoor unit and

tighten the first few threads by hand, Fig.22.

NOTE: The refrigerant pipes must be connected

to the valves on the outdoor unit with as little

stress as possible.

IMPORTANT: Before you continue, it is essential

that you read the following instructions carefully.

4. Now tighten the bottom screw connector first

and then the top screw connector using the

open-ended spanner. 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.23.

Ensure that the screw connectors do not skew

as you tighten them and work quickly. See the

next page for the proper torque.

IMPORTANT: Since the coupling works with

tapping rings, it may leak if you undo and

reconnect the pipes. This will also void the

warranty.

CAUTION: For your safety, always wear goggles

and work gloves when connecting the pipes.

respectively during connection.
