6 Checking of device and installation conditions

NOTE
In case of two or more flow switches installed with field
setting [2-24-3] activated (see "7.2.8 Mode 2: Field setting"
on page 36), be sure to use the flow switch that close the
contact in 5 seconds after the water pump operation
request signal turned on.
Failure to do so will result in malfunction.

Multifunction outputs
To monitor the outside unit operation or trigger field supplied
equipment connected to the outside unit, this RWEQ*T, series is
equipped with 5 output contacts.
General contact specifications: 220 V AC, 3 mA-0.5 A.
To connect these output signals, choose the applicable contacts in
the X3M terminal in the table below:

2 Make sure there is no faulty power wiring or loosening of a nut.
See "5.8.8 To connect the power supply" on page
3 Has the insulation of the main power circuit deteriorated?
Measure the insulation and check the insulation is above
regular value in accordance with relevant local and national
regulations.
For those doing pipe work
1 Make sure piping size is correct.
See "4.3 Refrigerant pipe size and allowable length" on page 11
and "4.3.3 To select refrigerant branch kits" on page
2 Make sure insulation work is done.
See "5.5 To insulate the refrigerant piping" on page
3 Make sure there is no faulty refrigerant piping.
