SERVICE MANUAL

R410A

• This manual describes about the model which is installed with the passive filter to the fan driving
circuit as the measure against the Europe Harmonic Regulation EN61000-3-12.

The indoor units are same as those of the existing models and they are not especially changed.

For the standard servicing method, refer to the FILE NO. A03-009, A04-008 and A05-004-1.

New models compliance with EMC: IEC61000-3-12

5-4. Refrigerant Recovery When Replacing the Compressor

n How to operate the system during repairing of the defective outdoor unit

MMY-MAP0501HT8(-E), MMY-MAP0601HT8(-E), MMY-MAP0801HT8(-E),
MMY-MAP1001HT8(-E), MMY-MAP1201HT8(-E)

<Work procedure>

1. Follow to the abovementioned “13-1. Refrigerant Recovery in the Troubled Outdoor Unit”.

2. Next, recover the refrigerant in the system by using a recovery device, etc.

The refrigerant amount to be recovered is determined based upon the capacity of the troubled outdoor unit.
(See the following table.)

Example) In a case of backup for 10HP-outdoor unit in 30HP system:

in the original system HP (30HP system) = 36.0kg

Refrigerant amount in system HP (20HP system) after backup = 27.0kg

Refrigerant amount to be recovered = 36.0 – 27.0 = 9kg

3. For the unit which refrigerant has been recovered, execute “Outdoor Unit Backup Setup” in another section.

All the work has finished.

n How to Check Fan Power Supply P.C. Board and Fan IPDU

The fan power supply P.C. board supplies DC power. It supplies DC280V for the fan IPDU, and DC12V and
DC7V for the control power supply respectively. If the control power is not supplied, a communication error
(Error code [E31]) is out.
