Rotating parts
Fan guards must be fitted at all times and not removed unless the main power supply has been
isolated. If you remove the wire fan guards when fitting ductworks, take alternative safety
measures to protect against the risk of injury from rotating fans.
Sharp edges
The fins on the air-cooled condenser coils have sharp metal edges. Frame rails, panels, and other
components may also have sharp edges. Take reasonable care when working in contact with the
coils or any components to avoid the risk of minor abrasions and lacerations, such as wearing
appropriate gloves.
Refrigerants and oils
Working with chiller vessels that are designed to contain contents under pressure must only be
conducted by fully qualified technicians who have been certified in accordance with EPA Section 608
of the Clean Air Act requirements for the US or equivalently the Federal Halocarbon Regulations
and the Refrigerant Code of Practice for Canada. This equipment is only intended for installation in
locations that are not accessible to the general public. Further, this equipment is not intended for
use by persons (including children) with reduced physical, sensory or mental capabilities, or lack
of experience and knowledge. Refrigerant R-454B is classified as an A2L refrigerant and must be
handled in accordance with all governing regulations. Failure to meet this requirement can result in
damage to equipment, release of refrigerant into the environment, contamination of the operating
space for the equipment and pose a risk of personal injury or death. It is the responsibility of any
service technician or operator to adhere to these requirements. Refer to Chiller A2L Refrigerant
Application Data, 160.00-AD10 for more details regarding the application and use of A2L refrigerants.
Refrigerants and oils used in the unit are generally non-toxic and non-corrosive. However, use
gloves and safety glasses when working on the unit. The buildup of refrigerant vapor, from a leak
for example, does pose a risk of asphyxiation in confined or enclosed spaces and attention must be
given to good ventilation.
Use only the refrigerant and oil specifically designated for the unit. Any other type of refrigerant or
oil may cause damage to the equipment and voids the warranty.
High temperature and pressure cleaning
Do not use high temperature and pressure cleaning methods, for example steam cleaning, on any
part of the pressure system as this may cause operation of the pressure relief devices. Also avoid
using detergents and solvents, which may cause corrosion.
Emergency shutdown
In case of emergency, the control panel is fitted with an incoming supply circuit breaker switch that
acts as the emergency stop device. When operated it removes all the electrical supply, excluding
the customer voltage, to the control panel and the unit shuts down. The emergency stop only
interrupts control power. Use the main circuit breaker when working in the unit.
