Split packaged air-cooled water chiller
4P508019-1D – 2019.11
NOTICE
▪ Air in the water circuit can cause malfunctioning. During
filling, it may not be possible to remove all the air from
the circuit. Remaining air will be removed through the
automatic air purge valves during the initial operating
hours of the system. Additional filling with water
afterwards may be required.
▪ To purge the system, use the special function as
described in "7Commissioning"[430].
NOTICE
The water pressure indicated on the manometer will vary
depending on the water temperature (higher pressure at
higher water temperature).
However, at all times water pressure shall remain above
1bar to avoid air entering the circuit.
NOTICE
Make sure water quality complies with EU directive
98/83EC.
INFORMATION
The unit may dispose of some excessive water through the
pressure relief valve.
5.7.3 To insulate the water piping
The piping in the complete water circuit MUST be insulated to
prevent condensation during cooling operation and reduction of the
heating and cooling capacity.
To prevent the freezing of the outdoor water piping during winter
time, the thickness of the sealing material MUST be at least 13mm
(with λ=0.039W/mK).
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.
5.8 Connecting the electrical wiring
5.8.1 Field wiring: Overview
▪ Most field wiring on the unit is to be made on the terminal blocks
inside the electrical component boxes. To gain access to the
terminal blocks, remove the electrical component box service
panel. See "5.1Opening the units"[410].
▪ Cable tie mountings are provided at the wiring entries of the
electrical component box.
The wiring diagram is delivered with the unit, located at the inside of
the switch box cover.
5.8.2 To route and fix the power supply
NOTICE
When routing the remote control cord and inter-unit wiring,
secure clearance of 50mm or more away from the power
wiring. Ensure that the power wiring does not contact any
heated sections. When wiring, pay attention not to detach
the acoustic insulators from the compressor.
To route and fix the power supply of the outdoor unit
▪ Route the power wiring and the transmission wiring through a
conduit hole.
▪ Route the power wiring though the upper hole in the left side plate,
from the front position of the main unit (through the conduit hole of
the wiring mounting plate), or from a knockout hole in the unit's
bottom plate.
