Manufacturer model and installation verification

Exact model FJX5557MWHCS: Dometic FreshJet 5 White rooftop air conditioner with 15,000 BTU/h nominal cooling capacity and manufacturer-listed 12.8A compressor rated-load current. This is a cooling-only rooftop unit, not a heat pump. Dometic's technical table lists 115V AC, 60Hz single-phase operation. Electrical protection and fan ratings should be checked against the full model identification and current installation instructions.

Replacement fit check: Existing Penguin II replacement information in this listing is retained. Before replacing an older unit, verify the roof opening, mounting support, gasket arrangement, duct or non-ducted ceiling assembly, control-board generation and thermostat connection. Similar roof dimensions or capacity do not by themselves confirm that an existing electrical control system can be reused. Interior air-distribution equipment and control hardware may be required separately.
