PORTABLE AIR-CONDITIONERS

JANUARY '94 - New package

In the next packages of portable air-conditioners there will be modified pieces of polystyle: the basement and the four angulars. We inform you that it will be possible to replace the new polystyle basement on the old package, only if you change the four angulars too. There is , anyway, the chance to replace only the new polystyle basement and that is to put between the basement itself and the angulars, a piece of plastic or wood (i.e. - it is possible to use the castor stoppers of the airconditioners), to avoid the wood central strands of the old angulars damage the new basement which is completely made of polystyle.

August '94 - Air conditioner PAC ASR production '93 - '94

We want to inform you that on the above appliance from production 1993 onwards, a new type of electronic delayer ( code 521340 ) has been mounted. The compressor relay is directly mounted on this electronic device.

OCTOBER '94 - Electronic board of PINGUINO model PAC19E

The electronic board, for Pinguino PAC19E manufactured in 1989 with code 521223, is not available anymore. It is possible to replace it with the electronic board with code 521255, but it is necessary to follow the instruction below.

The operation to be done are the following:

- the three connection for the ventilator speeds [grey(LO) - black (CV) - brown (HI)], for the water pump [Orange (P)] remain the same for the two boards.

- it is necessary to use the float switch with code 512048

- the light blue wire coming from the terminal block position 2 (see old diagram) must be connected to NEUTRAL (N) of the new board.

- the blue wire coming from terminal block position 1 (see old diagram) must be connected to LIVE (TH) of the new board.

- the new board must be mounted in order to be well insulated from the appliance frame.

JANUAR '95 - NEW CONTROL BOARD FOR PAC 36 PRODUCED IN 1995

In the mobile air conditioner PAC36, produced in 1995, there has been mounted a different electronic control board than in 1994. The two boards differ from each other in one of the cable-connectors, which number of connections has been reduced from four to three. Because of this difference the two boards are not interchangeable. For conditioners from 1994 with the old board, please order spare part nr. 521436; for conditioners build in 1995, please order spare part nr. 521444. You can recognize the year of production by the serial number. Conditioners, which serial number starts with 4, are build in 1994; those which start with 5, are constructed in 1995. Please countercheck with figures below, which is the board you have to order.

FEBRUARY '95: PAC 19ECO; PAC 25 AND PAC 25 ECO: NEW ELECTRONIC BOARD FOR FLOAT SWITCH

In the airconditioners Pac 19 Eco, Pac 25 and Pac 25 Eco you might find two diffrent types of electronic boards for the float switch. You can easely distinguish the two boards by their size and the different wire connections.One board has two multiple connectors and some single wires soldered on it, the other has three multiple connectors and no sigle wires on it (see figure underneath). The boards are not interchangeable: you have to order the board mounted origionally. Referens can be made also to the series number. The conditioners with board code 521289 have a single "A" at the end of the series number. The conditioners with board code 521573 have an double "AA" at the end of the series number. You will also find the code number printed on the board itself.

PORTABLE AIR-CONDITIONERS

MARCH '95: PAC 26 WITH NEW ELECTRONIC

The portable air conditioner, model PAC 26, produced from March 95 (from Serial nr. 5 09 P 11000 A) onwards, there has been introduced a different set of electronic boards (thermostat - control- and relay board). As consequence, you could find in this year of production two different sets of electronic boards. While the functions of the conditioner have not been changed, the connections on the boards as well as the distribution of the various electronic components are different and the boards are not interchangeable. On appliances with the Serial nr. until 5 09 P 11000A you will have to order the electronic boards according the exploded

view of 1993 and the wiring diagrams according to the tecnical documentation nr. 94025, on appliances with serial nr. from 5 09 P 11000A please order according to the exploded view of '95 and follow the wiring diagrams of documentation nr.

95002.

The main differences between new and old boards are shown below, in order that you might easily distinguish one from another. THERMOSTAT BOARD

Note the different positions of relais, resitor (VE) between both boards and the long connector on the old board and the many separated ones on the new board.

SEPTEMBER '95: PAC 36 WITH NEW RELAY BOARD

On the relay board of the air-conditioner model PAC 36 has been changed the position of the compressor connections. The two wires are now connected to the position 3 and 4 of the 6-pole-connector instead being connected directly onto the relay as with the old version. Both types of relay board are interchangeable, following the wiring diagram below.

Because of the interchangeability, the code number of the board has remained invaried.
