VETHY / FLEET AND OEM BUYER GUIDANCE
Plan an RV AC upgrade around space, power and comfort.
An RV AC upgrade should start with the existing installation and the desired operating duty. A change of refrigerant or compressor label alone does not establish a better fit, lower noise or longer battery runtime.
Document what is already installed
Record the current unit, power source, roof opening, interior air-distribution arrangement and available clearances. Photograph the roof structure and nearby equipment.
A replacement unit’s external dimensions do not establish the required opening or structural compatibility. Confirm the approved interface before removing or cutting anything.
Define cooling and heating requirements
Describe occupied zones, glazing, insulation, climate and operating duration. State whether heating is required and how the RV will be powered at the intended sites.
EcoMax 3S is a split heating-and-cooling reference; VS02-PRO is a rooftop cooling reference. Suitability still requires review of the actual vehicle.
Budget the complete conversion
List mounting, wiring, protection, batteries or charging changes, sealing, drainage, commissioning and service access. Clarify who approves structural and electrical work.
Do not assume an existing solar installation or shore-power arrangement automatically supports a new DC air conditioner. Ask for a complete power-system review.
Agree a handover check
Confirm the installed configuration, controls, drainage, operating observations and support documents before accepting the work. Retain photographs and the parts list.
Prepare the vehicle compatibility checklist and RFQ brief for a model-specific proposal.

FROM SELECTION TO A DEFINED PROJECT
Bring the vehicle brief.
Share the truck model, voltage, operating climate, installation photos and intended quantities. VETHY can review the proposed configuration and the evidence needed for your application.
