6.2.3 Installation site requirements of the
indoor unit
INFORMATION
Also read the precautions and requirements in the
"General safety precautions" chapter.
▪ Mind the measurement guidelines:
Maximum refrigerant piping length between indoor
unit and outdoor unit ERHQ: 75 m
(95 m)
(a)
ERLQ: 50 m
(70 m) (a)
Minimum refrigerant piping length between indoor
unit and outdoor unit 3 m
Maximum height difference between indoor unit and
outdoor unit 30 m
Maximum distance between the 3‑way valve and
the indoor unit (for installations with domestic hot
water tank) 3 m
Maximum distance between the domestic hot water
tank and the indoor unit (for installations with
domestic hot water tank) 10 m
(a) Parenthesised figure represents the equivalent length.
▪ Mind the following spacing installation guidelines:
≥1
150
200 200
10 10 500
(mm)
Do NOT install the unit in places such as:
▪ In places where a mineral oil mist, spray or vapour may be
present in the atmosphere. Plastic parts may deteriorate and fall
off or cause water leakage.
▪ Sound sensitive areas (e.g. near a bedroom and the like), so that
the operation noise will cause no trouble.
▪ The foundation must be strong enough to bear the weight of the
unit. Take the weight of the unit with a domestic hot water tank full
of water into account.
Make sure, in the event of a water leak, water cannot cause any
damage to the installation space and surroundings.
▪ In places with high humidity (max. RH=85%), for example a
bathroom.
▪ In places where frost is possible. Ambient temperature around the
indoor unit should be >5°C.
▪ The indoor unit is designed for indoor installation only and for
ambient temperatures ranging from 5~35°C.
6.3 Preparing refrigerant piping
6.3.1 Refrigerant piping requirements
INFORMATION
Also read the precautions and requirements in the
"General safety precautions" chapter.
▪ Piping material: Phosphoric acid deoxidised seamless copper.
▪ Piping diameter:
Liquid piping Ø9.5 mm (3/8")
Gas piping Ø15.9 mm (5/8")
▪ Piping temper grade and thickness:
Outer diameter
(Ø)
Temper grade Thickness (t) (a)
9.5 mm (3/8") Annealed (O) ≥0.8 mm
t
Ø
15.9 mm (5/8") Annealed (O) ≥1.0 mm
(a) Depending on the applicable legislation and the unit's
maximum working pressure (see "PS High" on the unit
name plate), larger piping thickness might be required.
6.3.2 Refrigerant piping insulation
▪ Use polyethylene foam as insulation material:
▪ with a heat transfer rate between 0.041 and 0.052 W/mK (0.035
and 0.045 kcal/mh°C)
▪ with a heat resistance of at least 120°C
