WARNING CAUTION To prevent refrigerant leak, contact your dealer. When the system is installed and runs in a small room, it is required to keep the concentration of the refrigerant, if by any chance coming out, below the limit. Otherwise, oxygen in the room may be affected, resulting in a serious accident. Never expose little children, plants or animals directly to the air flow. Adverse influence to little children, animals and plants may result.
2. WHAT TO DO BEFORE OPERATION This operation manual is for the following systems with standard control. Before initiating operation, contact your dealer for the operation that corresponds to your system type and mark. If your installation has a customized control system, ask your dealer for the operation that corresponds to your system. 5. OPERATION Operation range Use the system in the following temperature and humidity ranges for safe and effective operation.
For systems without cool/heat changeover remote control switch (See figure 3) 1 NOTE ■ The heating capacity drops when the outside temperature falls. If this happens, use another heating device together with the unit. (When using together with appliances that produce open fire, ventilate the room constantly.) Do not place appliances that produce open fire in places exposed to the air flow from the unit or under the unit.
6.3. Adjusting the air flow direction 6.5. Precautions for group control system or two remote controller control system Refer to the operation manual of the remote controller. Movement of the air flow flap (See figure 7) For the following conditions, a micro computer controls the air flow direction which may be different from the display. COOLING This system provides two other control systems beside individual control (one remote controller controls one indoor unit) system.
. MAINTENANCE 8.1. Symptom 4: The fan strength does not correspond to the setting. ■ Maintenance after a long stop period (eg. at the beginning of the season) ■ Check and remove everything that might be blocking inlet and outlet vents of indoor units and outdoor units. ■ Clean air filters and casings of indoor units. Refer to the operation manual supplied with the indoor units for details on how to proceed and make sure to install cleaned air filters back in the same position.
■ A hissing sound which is heard at the start or immediately after stopping operation or defrost operation. This is the noise of refrigerant caused by flow stop or flow change. ■ Symptom 8.3: Outdoor unit ■ When the tone of operating noise changes. This noise is caused by the change of frequency. When the unit is used for the first time in a long time. This is because dust has gotten into the unit.
11. AFTER-SALES SERVICE AND WARRANTY NOTE 1. Table 1 indicates main components. Refer to your maintenance and inspection contract for more details. 2. Table 1 indicates recommended intervals of maintenance cycles. However, in order to keep the unit operational as long as possible, maintenance work may be required sooner. Recommended intervals can be used for appropriate maintenance design in terms of budgetting maintenance and inspection fees.
