7. CONNECTING THE COOLANT PIPES
7.1 Connecting and disconnecting the coolant pipes
TOOLS NEEDED
- You will require the following tools to carry out this installation work correctly:
1x open-ended spanner, 19 mm
1x open-ended spanner, 22 mm/24mm
1x open-ended spanner, 24 mm/27mm
1x Allen key, 5 mm
1x Philips screwdriver
1x leak detection spray or alternatively soap suds (water/detergent mix)
IMPORTANT INFORMATION
• Follow the detailed instructions for connecting the refrigerant pipes to the indoor unit and outdoor
unit. We can only provide a warranty if the lines are installed correctly as described in the instructi-
ons.
• Do not remove the sealing caps and stoppers until immediately before you install the lines.
• To prevent leaks, ensure that the quickrelease screw connections are absolutely free of dirt. Moisture
or foreign bodies will adversely affect the function of the quickrelease connectors, leading to a risk
of refrigerant loss (not covered by the warranty).
• Only install refrigerant lines outdoors in dry weather.
• The refrigerant lines must not be installed and then plastered over.
• Please make sure that refrigerant is never allowed to enter the environment. Improper handling of
refrigerant may be harmful to health. Always wear work gloves and goggles when handling refrige-
rant.
• 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.

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.
• 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 cus-
tomer service team or a refrigeration contractor.
