2 SAFETY PRECAUTION Cautions for units utilizing refrigerant R410A Use the following tools specifically designed for use with R410A refrigerant. Do not use the existing refrigerant piping. The old refrigerant and lubricant in the existing piping contains a large amount of chlorine which may cause the lubricant deterioration of the new unit. The following tools are necessary to use R410A refrigerant.
[1] Cautions for service (1) Perform service after recovering the refrigerant left in unit completely. (2) Do not release refrigerant in the air. (3) After completing service, charge the cycle with specified amount of refrigerant. (4) When performing service, install a filter drier simultaneously. Be sure to use a filter drier for new refrigerant. [2] Additional refrigerant charge When charging directly from cylinder · Check that cylinder for R410A on the market is syphon type.

How to perform the up/down operation using wired remote controller (PAR-21MAA) N General Operation * Raise or lower all the air intake grilles managed by the remote controller at the same time. Install the remote controller in a place where you can observe all the air-conditioners. Otherwise, the lowering grille may make contact with something and cause damage to it. 1) Ensure that the air-conditioner is not running. * The up/down operation mode is only available when the air-conditioner is "OFF".
■ Up/down operation with the individual specified air-conditioner (when used in combination with Mr. SLIM model) * Raise or lower the air intake grille of the specific air-conditioner that you select from all that are managed by that remote controller. 1) Ensure that the air-conditioner is not running. Ensure that the air-conditioner is not running. Warning: * The up/down operation mode is only available when the • Otherwise, it may cause an injury or a failure. air-conditioner is "OFF".
