being controlled. Disconnect electrical power before servicing the equipment.
Static sensitive components. A static discharge while handling electronic circuit boards can cause damage to the components. Discharge any static electrical
charge by touching the bare metal inside the control panel before performing any service work. Never unplug any cables, circuit board terminal blocks, or power
plugs while power is applied to the panel.
When moving refrigerant to/from the chiller from an auxiliary tank, a grounding strap must be used. An electrical charge builds when halo-carbon refrigerant
travels in a rubber hose. A grounding strap must be used between the auxiliary refrigerant tank and the chiller's end sheet (earth ground), which will safely take
the charge to the ground. Damage to sensitive electronic components could occur if this procedure is not followed.
This equipment generates, uses, and can radiate radio frequency energy. If not installed and used in accordance with this instruction manual, it may cause
