SECTION 1 – GENERAL CHILLER INFORMATION AND SAFETY

QUALITY ASSURANCE

Units comply with the following directives:
• GB/T 18431-2014 Steam and Hot Water Lithium
Bromide Absorption Chiller
• UL 1995 2011 Ed.4 + R: 03Oct2014 Standard for
Safety Heating and Cooling Equipment
• UL 508A Industrial Control Panel
• NFPA70 National Electrical Code
• NFPA79 Electrical Standard for Industry Machine
• Pressure vessel will follow ASME
The unit must be grounded. No installation or main-
tenance work should be attempted on the electrical
equipment without first switching the power off, then
isolating and locking-off the power supply. Servicing
and maintenance on live equipment must not be at-
tempted. No attempt should be made to gain access to
the control panel or electrical enclosures during normal
operation of the unit.
Components may also have sharp edges. Reasonable
care should be taken when working in contact with
any components to avoid risk of minor abrasions and
lacerations.

EMERGENCY SHUTDOWN

In case of emergency, the control panel is fitted with
an incoming supply circuit breaker with a red handle.
See the picture below. Turn the handle counter clock-
wise to shut down the chiller.

High Temperature and Pressure Cleaning

High temperature and pressure cleaning methods (e.g.,
steam cleaning) should not be used on any part of the
pressure system as this may cause operation of the
pressure relief devices. Detergents and solvents, which
may cause corrosion, should also be avoided.
