The unit must be grounded. No installation or maintenance 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 attempted. 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. Turn the handle counter clockwise to shut down the chiller.

High temperature and pressure cleaning
High temperature and pressure cleaning methods (for example, steam cleaning) must not be
used on any part of the pressure system as this can cause operation of the pressure relief devices.
Detergents and solvents, that can cause corrosion, must also be avoided.
