START UP AND OPERATION
See the merchandiser's Technical Data Sheet for refrigerant settings and defrost require ments. Bring merchandisers down to the operating
temperatures listed on the data sheet. Merchandiser(s) must operate for 24 hours before loading products.
Monitor case temperature regularly to ensure it is at the proper level. Monitor the unit for any unusual noises or vibrations and address them
promptly to prevent further problems. Check the electrical connections and wiring for any issues.
Excessive ambient conditions may cause condensation and therefore sweating of doors. Facility operators should monitor doors and floor
conditions to ensure safety of persons.
