who have experience with this type of equipment.
!
DANGER
!
LOCK OUT/LABEL all power sources before starting, pressurizing, depressurizing or shutting down the chiller. Disconnect electri-
cal power before servicing equipment. More than one disconnection may be required to deenergize the unit. Failure to follow this
warning to the letter can result in serious injury or death. Be sure to read and understand the installation, operating and service
instructions in this manual.
!

!
WARNING

!
WARNING
!
Electric shock danger. Improper handling of this equipment can cause personal injury or equipment damage. This equipment must
be properly grounded. Control panel connections and maintenance should be performed only by personnel knowledgeable in the
operation of the equipment being controlled. Disconnect electrical power before servicing equipment. Be sure to install a earth
leakage breaker. Failure to install a earth leakage breaker may result in electric shock or fire.
!
WARNING
!
If refrigerant leaks from the unit, there is a potential choking danger as the refrigerant will displace air in the immediate area. Be
sure to follow all applicable published industry-related standards and local, state, and federal statutes, regulations, and codes if
refrigerant is produced. Avoid exposing refrigerant to an open flame or other ignition source.
!
WARNING
!
Polyolester oil, commonly referred to as POE oil, is a synthetic oil used in many refrigeration systems and may be present in this
Comfort Flex product. POE oil, if it ever comes in contact with PCV/CPVC, will coat the inside wall of the PVC/CPVC pipe and cause
environmental stress fractures. Although there is no PCV/CPCV pipe in this product, keep this in mind when selecting piping mate-
rials for your application, as system failure and property damage could occur. Consult the pipe manufacturer’s recommendations to
determine appropriate pipe applications.
!
CAUTION
!
Static sensitive components. Static discharge during handling of the electronic circuit board can cause damage to components.
Use a static strap before performing any service work. Never unplug any cables, circuit board terminal blocks, or power plugs while
power is applied to the panel.
!
CAUTION
!
When moving refrigerant to/from the cooler using an auxiliary tank, a grounding strap should be used. An electrical charge builds
up when halo-carbon refrigerant travels in a rubber hose. A grounding strap should be used between the auxiliary refrigerant tank
and the cooler end sheet (ground to ground), which will safely carry the charge to ground. Failure to follow this procedure may result
in damage to sensitive electronic components.
