FIELD WORK INSTRUCTIONS

6.1 Caution for Refrigerant Leakage

Refer to Section 3 “Troubleshooting” when dealing with problems or difficulties.

If you cannot solve the problem, contact your distributor or contractor.

● Special Attention Regarding Refrigerant Gas Leakage

Make sure that the entire VRF system meets ASHRAE Standard 15 or, any local codes, regarding Safety.

The ASHRAE Standard 15-2013 provides safeguards for life, limb, health, property, and prescribes safety

requirements.

The standard is recognized as the main guide for personal safety involving refrigeration systems. It strives

to ensure a safe application of refrigerant systems by limiting the maximum charge so that a complete

discharge due to a leak into a small, occupied, and enclosed room can never exceed the allowable limit.
