NOTES IF REPLACING A DOMETIC AU-HV
The CTM AH 230V Marine Air Conditioning Units work as an excellent replacement for the Dometic AU-HV Air Handlers.
There are some specs that should be taken into consideration when replacing one of the units previously mentioned
- Waterline connections need to be adapted from 1/2" to 3/4". The CTM air handlers will come with the needed adaptor.
- Dimensions wise the CTM AH is very similar to the Dometic and Cruisair air handler units, so there shouldn’t be any issues when replacing your current unit with the AH. However, it is recommended that you double-check your current installation space and the CTM AH’s specs in order to avoid any issues when installing.
