Tundish
(fi eld supply)
1. Connect the tundish and route the discharge pipe as shown
above. Tundish should be visible and positioned away from frost
environment and electrical components.
2. The tundish should be fi tted vertically and as close to the safety
device as possible and within 600mm of the device.
3. The tundish should be visible to users and positioned away from
electrical devices.
4. The discharge pipe from the tundish should be terminate in a safe
place where there is no risk to person nearby to the discharge, be
of metal construction and:
A) Be at least one pipe size larger than the nominal outlet size of
the safety device unless its total equivalent hydraulic resistance
exceeds that of a straight pipe 9m long. Bends must be taken
into account in calculating the fl ow resistance.
B) Have a vertical section of pipe at least 300mm long, below the
tundish before any elbows or bends in the pipework.
C) Be installed with a continuous fall.
D) Have discharges visible at both the tundish and fi nal point of
discharge.

Fixing of Power Supply Cable and Connecting Cable
1. Connecting cable between Tank Unit and Outdoor Unit shall be
approved polychloroprene sheathed fl exible cord, type designation
60245 IEC 57 or heavier cord. See below table for cable size requirement.

•
Ensure the colour of wires of Outdoor Unit and the terminal no.
are the same to the Tank Unit respectively.
•
Earth wire shall be longer than the other wires as shown in the
fi gure for the electrical safety in case of the slipping out of the
cord from the Holder (Clamper).
2. An isolating device must be connected to the power supply cable.
•
Isolating device (disconnecting means) should have minimum
3.0 mm contact gap.
•
Connect the approved polychloroprene sheathed power supply
1 cord and power supply 2 cord and type designation 60245
IEC 57 or heavier cord to the terminal board, and to the other
end of the cord to isolating device (Disconnecting means).

3. To avoid the cable and cord being damaged by sharp edges, the cable
and cord must be passed through a bushing (located at the bottom
of Control Board) before terminal board. The bushing must be used
and must not be removed.
