1 PAW-160MAH3M:
● PAW-160MAH3M can be installed in combination with all ECOi outdoor units (including Mini ECOi
(2-pipe), ECOi 2-pipe and ECOi 3-pipe units) like any other standard indoor unit.
● Mixed installation with standard indoor units is possible with all ECOi outdoor units (as above). However,
in this case one additional RAP valve (CZ-P160RVK2) must be installed in the unit connection pipe, un
-
less the complete system is exclusively used in cooling only operation.

PAW-280MAH3M:
● PAW-280MAH3M can be installed in combination with all ECOi outdoor units (including Mini ECOi
(2-pipe), ECOi 2-pipe and ECOi 3-pipe units) with a nominal cooling capacity of at least 8 HP like any
other standard indoor unit.
● Mixed installation with standard indoor units is possible with all ECOi outdoor units (as above). However,
in this case two additional RAP valves (2 x CZ-P160RVK2) must be installed in the unit connection pipe,
unless the complete system is exclusively used in cooling only operation.
● When PAW-280MAH3M is installed in combination with an ECOi 3-pipe outdoor unit, either two 16 kW
solenoid valve kits or two ports of a 16 kW multi-port heat recovery box respectively (CZ-P...HR3) need
to be used in parallel installation for each AHU DX coil.

PAW-560MAH3M:
● Mixed installation with standard indoor units is not allowed.
● Connection to ECOi 3-pipe systems is not allowed.
4 In case of a multiple AHU Kit combination within one refrigerant system, those kits must share the same AHU hous
-
ing including fan, and they have to be “group-wired” and operate as a single group. In this case you must disconnect
the CZ-RTC6BL controller and CZ-CAPBC2 boards (ACC-SP1A PCB) from all but one AHU kit. It is irrelevant which
one is retained, there is no preference. The external connections need to be done only on the unit with the connected
CZ-CAPBC2 board.
