BASIC PARTS

All metal parts are fabricated on site and are introduced into assembly process:

  • Interior fan bracket – round metal ring with integrated nuts

  • Exterior fan bracket – round metal ring with mounting holes for screws

  • A4 and A6 washers, plastic spacers, M4x16 and M6x10 screws

  • Left and right part of the fan scroll

Basic Parts

DISASSEMBLY AND ASSEMBLY PROCESS

  • Remove the connection boxes and disconnect the fan wires

  • Remove the screws holding the scroll in place. There is also a pair of screws which hold the back plate to scroll, they need to be removed.

  • There are clips that hold two halves of scroll together. Disconnect them gently and halves will disconnect themselves.

  • Remove the M6 screws.

  • Slide the fan out and remove the remaining screws for assembly to detach completely.

  • Place the fan Type 1 in and use the attached screws for mounting. Holes must be aligned

  • Push the scroll halves together to make a signal fan unit. Pieces must be aligned.

  • Use the same screws to mount back the scroll onto evaporator. Connect the wires afterwards.

Type 1 wiring

Line No. Signal Colour Function/assignment
L 1 brown Power supply 230 Vac,50/60Hz, see type plate for voltage range
N 2 blue Neutral conductor
Pwm 3 yellow PWM control input, electrically isolated
GND 4 white GND – Connection for control interface

Connect the wires in the following order:

UPPER CONNECTION (POWER BOX):

  1. BLUE to BLUE
  2. BROWN to RED

There is no YELLOW/GREEN wire because of plastic fan construction.

LOWER CONNECTION (PWM BOX):

  1. YELLOW to BROWN
  2. WHITE to BLUE

Setting the proper PWM parameter, reffered to type 1:
With long press on field ‘’service mode’’ (wrench icon) on the display, enter into service diagnostic.
The service menu with note ‘‘code’’ will appear. To enter the menu the code entry is required.
Fields FN1, FN2, FN3, FN4, FN5 in FN6, presents the numbers 1,2,3,4,5,6.
Enter the code for service menu 1166.
