Installation and maintenance manual

3.5 Laying coolant lines
● Check whether oil trap arc necessary.
– Required if Daikin Altherma EHS(X/H) is not installed at
ground level with the heat pump exterior unit (fig. 3-36,
H
O
≥ 10 m).
– At least one oil trap arc must be installed every 10 m dif-
ference in height (fig. 3-36, H = clearance from oil trap arc
to oil trap arc).
– Oil trap arc only required in gas line.
● In
stall lines with bending unit and an adequate clearance to
electrical lines.
● Only
solder with light nitrogen flow
(hard soldering only).
● Do not apply heat insulation to joins until after start-up (for
purposes of leakage search).
● Esta
blish flange connections and connect to the units.
( Pay attention to the tightening torque, see chapter 9.3
"Tightening torque").
