23. Cautions
Refrigerant Leak Check
Conduct a periodic refrigerant leak check to maintain product performance and secure storage of
refrigerant (Fluorocarbons). After completing installation, record the following results into this "Installation
and Maintenance Manual":
1. Results of a test for air-tight integrity
2. Total refrigerant charge volume dispensed (including a trim charge added following the installation)
3. Result of the refrigerant leak check
Then hand it over to users and ask them to retain for reference.
All periodic service and maintenance procedures must be conducted only by authorized and trained
personnel.
All the installation work of the air conditioning is completed.
Hand over this information to the building owner and request they maintain all the equipment manuals
and warranty.
Do NOT operate the air conditioning just to run checks on electrical wiring until preparations for the Test Run
phase is completed.
NOTICE
23.1 Limitation of Air Handler
• When the outdoor temperature is low and external static pressure is low then airÀ ow volume will not
become the setting.
• An application using the AP18 and AP60 air handler must be within an external static pressure of 0.4".
AirÀ ow volume at this external static pressure must be High: 674CFM Low: 490CFM for AP18 and
High: 1743CFM Low: 1661CFM for AP60.
