1. Detachment

1) Close the water supply source valve and the valve of

water pipe connected to the unit, carry out the

refrigerant recovery and then remove the refrigerant

and water pipes.

2) Carry out the detachment of item

(Electrical control

box) and item

(pipe cover plate).

3) Remove the screws for the heat exchanger assembly

fixing plate as shown below.(4x10, 7pcs.)

For the unit for 056 type:4x10, 8pcs.

4) Remove the heat exchanger assembly from the unit as

shown below.

5) Remove sensors, 2way valve coil and flow switch

attached the heat exchanger assembly.

6) Carry out installation by following the detachment

procedure in reverse.

CAUTION

• Be careful in the insertion direction of attaching the

sensor, as shown below.

• Be careful to attach the flow switch, as shown

item

(flow switch).

2. Attachment

1) Carry out installation by following the detachment

procedure in reverse.

NOTE:

• To attach the heat exchanger assembly on the proper

position, replace the heat exchanger assembly edge on

the enboss, as shown below.
