FINAL STAGES
WARNING:
- Use manual tools and equipment that are suitable for the in-
tended use.
- Always protect the connection cables and pipes to prevent their
being damaged, as they could cause gas leaks when damaged.
(Personal injury from cold burns).
- Recharge the refrigerant gas in accordance with the instruc-
tions provided on the product safety data sheet, wearing pro-
tective clothing, avoiding violent outlets of gas from the tank
or from the system's connections. (Personal injury from cold
burns).
1. Wrap some insulating material around the joints of the internal
unit and fasten it in place using electric (insulating) tape.
2. Fasten the extra part of the signal cable to the piping or to the ex-
ternal unit.
3. Fasten the piping to the wall (fi rst cover the pipes with electric in-
sulating tape) using some clips or otherwise insert the pipes in
plastic channels.
4. Seal the hole in the wall through which the piping passes so that no
air or water can fi lter through.
5. Outside, insulate all the bare piping, including all valves.
6. If the piping has to pass above the ceiling or via a warm damp place,
wrap all pipes with some extra insulating material available on sale
to prevent condensation from forming.
