DANGER
LOCKOUT/TAGOUT all power sources prior to starting, pressurizing, de-pressuring, or powering down the Chiller. Failure to follow
this warning exactly can result in serious injury or death. Be sure to read and understand the installation, operation, and service
instructions within this manual.
WARNING
Electric shock hazard. Improper handling of this equipment can cause personal injury or equipment damage. This equipment must
be properly grounded. Connections to and service of the MicroTech
®
III control panel must be performed only by personnel that are
knowledgeable in the operation of the equipment being controlled.
CAUTION
Static sensitive components. A static discharge while handling electronic circuit boards can cause damage to the 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 chiller using 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.
WARNING
Escaping refrigerant can displace air and cause suocation. Immediately evacuate and ventilate the equipment area. If the unit
is damaged, follow Environmental Protection Agency (EPA) requirements. Do not expose sparks, arcing equipment, open ame
or other ignition source to the refrigerant.
WARNING
Polyolester Oil, commonly known as POE oil is a synthetic oil used in many refrigeration systems, and may be present in this Daikin
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.
