SAFETY CONSIDERATIONS
Installation of this unit can be hazardous due to electrical com-
ponents and equipment location (such as a ceiling or elevated
structure). Only trained, qualified installers and service
mechanics should install and service this equipment.
When installing this unit, observe precautions in the literature,
labels attached to the equipment, and any other safety precau-
tions that apply.

• Use care in handling and installing this unit.
• Never pressurize any equipment beyond specified test
pressures. Always pressure test with an inert fluid or gas
such as clear water or dry nitrogen to avoid possible
damage or injury in the event of a leak or component
failure during testing. Always protect adjacent flamma-
ble material when welding or soldering. Use a suitable
heat-shield material to contain sparks or drops of solder.
Have a fire extinguisher readily available.
