Lockout/Tagout (LOTO)
Before performing Chiller maintenance, the energy sources associated with
the Chiller system must be lockedout and tagged out (LOTO). Hazard
control features added to the system (e.g., safety interlocks, EMO) are not a
substitute for turning off and locking out electrical or uid energy.
For chillers rated 20 Amps or less, electrical LOTO is accomplished by
removing the power cord on the rear of the chiller then closing and locking
the power receptacle locking device. For other chillers, electrical LOTO is
the responsibility of the user and can be provided by:
• Using the main disconnect (knife switch at system control cabinet).
• Disconnecting main power at the facility power source prior to the
system controller cabinet.
• In addition, follow all OSHA and local facility LOTO directives.
Drip Pan and Drain
The chiller is equipped with a secondary containment (drip pan) in case
there is a leak. The drip pan drain is located on the rear of the chiller.
Install the supplied nylon 1/4 turn quick disconnect (QD) tting into the
drain tting. The QD is barbed for a 1/2" ID hose.
Since the drip pan will not hold more than 110% of the reservoir volume,
connect the drain to guide the uid to an appropriate spillage location.
