MS Unit Installation
Note:
The maximum number of each group indoor units should be less than 4, and the maximum capacity of each group indoor
units should be less than 16kW.
If the indoor units do not have auto mode function, then each group of MS can be connected with four indoor units at most
for one time; otherwise, it can be connected with only one indoor unit at most.
Indoor units in the same group of MS cannot be operated in cooling or heating mode at the same time, or operated in
heating and air supplying mode at the same time; otherwise it will be mode conflict.
Connecting diagram 2
“MS02E/N1-C” and “MS04E/N1-C” which can be connected only one indoor unit.
Caution:
Do not let air, dust, or other impurities fall in the pipe system during the time of installation.
The connecting pipe should not be installed until the indoor and outdoor units have been fixed already.
Keep the connecting pipe dry, and do not let moisture in during installation.
The connecting copper pipes should be wrapped up by insulated materials (more than 10mm thick).
5.3 The procedure of connecting pipes
1. Connect the indoor unit first, and then connect the outdoor unit.
a) The pipe bend should be handled carefully, without damaging the pipe and insulation layer.
b) Before screwing up the flared nut, apply refrigerant oil at the outer surface of the pipeline flare and the
taper surface of the connection nut. Screw up the nut for 3~4 circles beforehand.
