Calculation of refrigerant

¥ Keeping valve of the outdoor unit colsed, be sure to charge

the liquid refrigerant into service port at liquid side.

¥ if the specified amount of refrigerant cannot be charged,

open fully valves of outdoor unit at liquid and gas

sides,operate the air conditioner in COOL mode under

condition that valve at gas side is a little returned to close

side (MAP0801*, MAP1001*, MAP1201* only), and then

charge refrigerant into service port at gas side. In this time,

choke the refrigerant slightly by operating valve of the

bomb to charge liquid refrigerant. The liquid refrigerant

may be charged suddenly, therefore be sure to charge

refrigerant gradually.

¥ When refrigerant leaks and refrigerant shortage occurs in

the system, recover the refrigerant in the system and

recharge refrigerant newly up to the correct level.

¥ Fill the additional refrigerant record column of the wiring diagram indication plate with the additional refrigerant amount

at installation work, total refrigerant amount and the name of the service ma who charged refrigerant at installation time.

¥ The total refrigerant amount means the total value of the refrigerant amount at shipment and the additional refrigerant

amount at installation time. the refrigerant amount at the shipment is one described on the ÒUnit nameplateÓ.

After cacuuming work, exchange the vacuum pump with the refrigerant bomb and then start the additional charging work of

refrigerant.

Calculation of additional refrigerant carge amount

Refrigerant charge amount at shipment from the factory does not include the refrigerant for pipe at the local site.

For refrigeranto to be charged in pipe at the local site, calculate the amount and charge it additionally.

NOTE) If the additional refrigerant amount indicates minus as the result of calculation, use the air conditioner without addition of

refrigerant.

Address Setup

Check that all the rotary switches, SW01, SW02, and SW03 on the interface P.C. board of the header unit are set

up to Ò1Ó.

If other error code is displayed on 7-segment [B], remove the cause of trouble referring to Ò9. TroubleshootingÓ.

Check that [L08] is displayed on 7-segment display [B] on the interface P.C. board of the header unit.(L08: Indoor

address unset up)

(If the address setup operation has already finished in service time, etc, the above check code is not displayed,

and only [U1] is displayed on 7-segment display [A].)

Display check on remote controller (In case of wired remote controller)

Check that a frame as shown in the following left figure is displayed on LC display section of the remote controller.

If a frame is not displayed as shown in the above right figure, the power of the remote controller is not normally

turned on. Therefore check the following items.

¥ Check power supply of indoor unit.

¥ Check cabling between indoor unit and remote controller.

¥ Check whether there is cutoff of cable around the indoor control P.C. board or not, and check connection failure

of connectors.

¥ Check failure of transformer for the indoor microcomputer.

¥ Check indoor control P.C. board failure.

Abnormal status

(Power is not normally turned on.)

(Power and operation stop)

Pre-check for Address Setup Automatic Address Setup

Turn on power of indoor/outdoor units.

(In order of indoor Outdoor)

After approx. 1 minute, check that U. 1. L08 (U. 1. flash)

is displayed in 7-segment display section on the interface

P.C. board of the header unit.

Push SW15 and start setup the automatic address.

(Max. 10 minutes for 1 line (Usually, approx. 5 minutes))

When the count Auto 1 Auto 2 Auto 3 is displayed

in 7-segment display section, and it changes from

U. 1. - - - (U. 1. flash) to U. 1.---(U.1.light) , the

setup finished.

When perform a central control, connect a relay

connector between [U1, U2] and [U3, U4] terminals in the

header unit.

Address setup procedure 1

Address setup procedure 2

Using SW13 and 14 on the interface P.C. board of the

header unit in each system, set up the refrigerant line

address for each system.

(At shipment from factory: Set to Address 1)

Note) Do not to duplicate with other refrigerant line.

Max. system address is up to 28

Check that the relay connectors between [U1U2] and [U3U4]

terminals are come out in all the header units to which the

central control is connected.

(At shipment from factory: No connection of connector)

Turn on power of indoor/outdoor.

(In order of indoor outdoor)

After approx. 1 minute, check that 7-segment display is

U.1.L08 (U.1. flash) on the interface P.C. board of the header

unit.

Push SW15 and start setup the automatic address.

U.1.---(U.1.flash) to U. 1.---(U.1.light) , the setup

finished.

Procedure 4. to 6. are repeated in other refrigerant lines.

How to set up resistance of the end terminal When all the

address setups have finished in the same refrigerant circuit

system, put the resistance of the end terminals in the same

central control line into one.

¥ Remain only SW03-2 of the header outdoor unit with the least

circuit system address number as it is ON.

(With end terminal resistance)

¥ Set up SW03-2 of the other header outdoor units to OFF.

(Without end terminal resistance)

Connect the relay connector between [U1U2] and [U3U4] of the

header unit for each refrigerant line.

Then set up the central control address.

(For the central control address setup, refer to the Installation

manual of the central control devices.)
