Polyolester Oil, commonly known as POE oil is a synthetic oil used in many
refrigeration systems, and may be present in this Daikin Applied product. POE
oil, if ever in contact with PVC/CPVC, will coat the inside wall of PVC/CPVC
pipe causing environmental stress fractures. Although there is no PVC/CPVC
piping in this product, please keep this in mind when selecting piping materials
for your application, as system failure and property damage could result. Refer
to the pipe manufacturer's recommendations to determine suitable applications
of the pipe.
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.
