WARNING
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.
CAUTION
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.
