Damage evident upon receipt should be noted on the freight bill.

Then file a claim with the delivering carrier. -
Page 4: Handling And Testing The Air Conditioner
The moisture that the enclosure air can contain is limited. If moisture flows from the drain tube continuously this can only mean that ambient air is entering the enclosure. Be aware that frequent opening of the enclosure’s door admits humid air that the air conditioner must then dehumidify. © 2019 nVent 89117142 - 4 - https://www.RSPSupply.com... -
Page 5: Standard And Optional Component Operation
Opening the enclosure can also introduce humidity back into the enclosure which will eventually condense on the evaporator coil and become part of the seal in the drain trap. © 2019 nVent 89117142 - 5 - https://www.RSPSupply.com... -

Do not attempt to operate the air conditioner while it is horizontal or on its side, back or front. • Operation of air conditioner in areas containing airborne caustics or chemicals can rapidly degrade sealing properties of materials, deteriorate filters, refrigeration coils, blowers and motors. Contact nVent Equipment Protection for special recommendations. See Maintenance on page 19. DANGER Danger: explosion hazard - do not energize, disconnect, or troubleshoot equipment unless power has been switched off or the area is known to be non-hazardous. - Page 11 Lors d’une installation sur une armoire, seule la face avant/latérale, l’entrée d’air ambiant et la sortie d’air ambiant peuvent être exposées à l’environnement. 89074387 Surface Mount Figure 1 Cut-out Drawing © 2019 nVent 89117142 - 11 - https://www.RSPSupply.com RSPSupply - 1-888-532-2706 - https://www.rspsupply.com/p-19602-hoffman-nhz360846g500-ac-460v-8500-btu-offshore-...

The drain trap can be cleaned by pouring soapy water into the face of the evaporator coil. An alternate method is to remove the panel underneath the condenser coil, locate the drain trap above the condensate evaporator pan, and blow compressed air through the tube. © 2019 nVent 89117142 - 19 - https://www.RSPSupply.com... -
