- Page 5 Take the following precautions to reduce the risk of property damage. ● Be careful that moisture, dust, or variant refrigerant compounds not enter the refrigerant cycle during installation work. Foreign matter could damage internal components or cause blockages. ● If air filters are required on this unit, do not operate the unit without the air filter set in place. If the air filter is not installed, dust may accumulate and breakdown may result.
- Page 6 Controls uses only refrigerants that have been approved for use in the unit’s intended home country or market. Johnson Controls distributors similarly are only authorized to provide refrigerants that have been approved for use in the countries or markets they serve. The refrigerant used in this unit is identified on the unit’s faceplate and/or in the associated manuals.
- Page 7 under pressure and never open pressurized system parts. ● Before installation is complete, make sure that the refrigerant leak test has been performed. If refrigerant gases escape into the air, turn OFF the main switch, extinguish any open flames and contact your service contractor.
- Page 8 ● Communication cabling shall be a minimum of 18-Gauge, 2-Conductor, Stranded Copper. Shielded cable must be considered for applications and routing in areas of high EMI and other sources of potentially excessive electrical noise to reduce the potential for communication errors. When shielded cabling is applied, proper bonding and termination of the cable shield is required as per Johnson Controls guidelines.

3. Maintenance 3.1 Precautions before Maintenance There are high-capacity electrolytic capacitors on the outdoor mainboard. Thus, even if the power is cut off, there is high voltage inside the capacitors and it needs more than 20 min. to reduce the voltage to safety value. Touching the electrolytic capacitor within 20 min. after cutting the power will cause electric shock. -
