SAFETY AND ENVIRONMENTAL CONCERNS
Your Mydax chiller was designed to give years of trouble-free operation. Features were designed into the unit to provide
early warning of failure mechanisms so that catastrophic failures can be avoided. Whether a chiller is at the factory or in
the field, diagnostic information gives Mydax engineers insight to the operation of each stage of the refrigeration and
recirculation circuits without having to attach service gauges.
1.
Warning & Error Messages: including coolant over-temperature warning & shutdown, low tank level warning
& shutdown and others (see ERROR MESSAGES section).
2.
System Diagnostics: including coolant & refrigerant temperatures, valve drives and parameters (see
DIAGNOSTIC DISPLAYS section).
3.
Hardware safeguards include a series-wired interlock circuit that protects refrigerant high pressure, thermal
protection of the pump and compressor motors.
Safety is important when using and servicing the chiller unit. Warning labels have been placed on the chiller in areas
where potentially harmful conditions exist and in this manual to bring attention to such conditions. This chiller uses
materials that are subject to environmental regulations; be sure to familiarize yourself with these components and their
associated regulations pertinent to your location.
Warnings have been categorized according to the following guide:
!
NOTICE
Provides information that is important for proper installation, operation, or maintenance, but not
critical to safety. Includes regulatory notices.
!
CAUTION
Identifies situations where improper action could cause damage to the equipment or product, or cause
minor physical discomfort.
!
WARNING
Identifies situations where improper actions could cause minor to moderate injury or impaired health.
!
DANGER
Identifies potentially lethal hazards, where improper actions could cause death, or serious injury or
disability, such as loss of sight or limb.
Label 1
This "Hot Surface" caution label has been placed on the inside of the chiller cabinet, near the compressor's discharge area
where the hot compressed refrigerant makes components as hot as 120
°
C. This label is placed on the Oil Separator and
the Muffler as well. The label indicates that the area is hot and should not be touched until the unit is allowed to cool
down.
