NOTICE
In cold areas, do NOT use a drain socket, hose and caps
(1, 2) with the outdoor unit. Take adequate measures so
that the evacuated condensate CANNOT freeze.
1 Install drain caps 1 and 2 (accessory). Make sure the edges of
the drain caps close off the holes completely.

Piping installation
5.1
Preparing refrigerant piping
5.1.1
Refrigerant piping requirements
NOTICE
The piping and other pressure-containing parts shall be
suitable for refrigerant. Use phosphoric acid deoxidised
seamless copper for refrigerant.
▪ Piping material: Phosphoric acid deoxidised seamless copper.
▪ Flare connections: Only use annealed material.
▪ Piping diameter:
Liquid piping Ø6.4mm (1/4")
Gas piping
Ø12.7mm (1/2")
▪ Piping temper grade and thickness:

Depending on the applicable legislation and the maximum
working pressure of the unit (see "PS High" on the unit name
plate), larger piping thickness might be required.
5.1.2
Refrigerant piping insulation
▪ Use polyethylene foam as insulation material:
▪ with a heat transfer rate between 0.041 and 0.052W/mK (0.035
and 0.045kcal/mh°C)
▪ with a heat resistance of at least 120°C
▪ Insulation thickness

If the temperature is higher than 30°C and the humidity is higher
than RH80%, the thickness of the insulation materials should be at
least 20 mm to prevent condensation on the surface of the
insulation.

Connecting the refrigerant piping
DANGER: RISK OF BURNING/SCALDING
CAUTION
▪ No brazing or welding on site for units with R32
refrigerant charge during shipment.
▪ During installation of the refrigeration system, joining of
parts with at least one part charged shall be performed
taking into account the following requirements: inside
occupied spaces non-permanent joints are NOT
allowed for R32 refrigerant except for site made joints
directly connecting the indoor unit to piping. Site made
joints directly connecting piping to indoor units shall be
of non-permanent type.
5.2.1
To connect the refrigerant piping to the
outdoor unit
▪ Piping length. Keep field piping as short as possible.
▪ Piping protection. Protect the field piping against physical
damage.
