4. FINAL STAGES

WARNING:
- Use manual tools and equipment that are suitable for the in-
tended purpose.
- 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, while wearing
protective clothing and avoiding sharp bursts of gas from the
tank or from the system 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 (first cover the pipes with electric insu-
lating tape) using some clips or otherwise fit the pipes into plastic
channels.
4. Use a suitable seal to fill in the hole in the wall through which the
piping passes so that no air or water can filter 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.

3. Are the buttons for the set-point and TIMER working properly?
4. Do all the LEDs come on?
5. Are the flaps used to direct the air flow efficient?
6. Is the condensation drained regularly?

- EXTERNAL UNIT

1. Is there any noise or vibration during operation?
2. Could the noise, air flow or condensation drainage disturb the
