Ɣ

This system should be installed by personnel certi

¿

 ed by Johnson Controls, Inc. Personnel must be 

quali

¿

 ed according to local, state and national building and safety codes and regulations. Incorrect 

installation could cause leaks, electric shock, 

¿

 re or explosion. In areas where Seismic ‘’Performance 

requirements are speci

¿

 ed, the appropriate measures should be taken during installation to guard 

against possible damage or injury that might occur in an earthquake if the unit is not installed correctly, 
injuries may occur due to a falling unit.

 

Ɣ

Use appropriate Personal Protective Equipment (PPE), such as gloves and protective goggles and, 
where appropriate, have a gas mask nearby. Also use electrical protection equipment and tools suited 
for electrical operation purposes. Keep a quenching cloth and a 

¿

 re extinguisher nearby during brazing. 

Use care in handling, rigging, and setting of bulky equipment.

 

Ɣ

When transporting, be careful when picking up, moving and mounting these units. Although the unit may 
be packed using plastic straps, do not use them for transporting the unit from one location to another. 
Do not stand on or put any material on the unit. Get a partner to help, and bend with your knees when 
lifting to reduce strain on your back. Sharp edges or thin aluminum 

¿

 ns on the air conditioner can cut 

¿

 ngers, so wear protective gloves.
