Notes if replacing a Dometic DTU16, DTG16 or ECD16 – 230V

The CTM CT-16H marine air conditioning unit works as a good replacement for the Dometic DTG16 – 230V (205162176), DTU16 – 230V (205162160), or ECD16 – 230V (207500017). There are some specs that should be taken into consideration when replacing one of the units previously mentioned.

– Because the CT-16H 230V unit comes with the Universal Control board, it will work with the controller you currently have. Supported controllers included: SMXir, Passport I/O, Smart Touch, Elite II.

– Waterline connections should be the same as the unit you are replacing; the CT unit has a standard 5/8″ water connection.

– The CT-16H 230V unit has a 6 inch ducting ring whereas the Dometic comes with a 7 inch. It is a quick replacement as the ducting can be easily cinched down with a clamp.

– Dimensions wise this unit is very similar to the one you are replacing, so it shouldn’t be a major issue. However, it is suggested you double-check in order to avoid any issues when installing.
