Isotherm ASU Automatic Start-Up systems are designed for installation in existing cool boxes, mainly in sailing yachts where battery power is at a premium. The microprocessor controlled ASU system dramatically reduces power consumption while supplying refrigeration in abundance.

The ASU circuitry senses when abundant power is available from the engine alternator, or even a solar panel installation, and speeds up the compressor to rapidly freeze the holding plate. When the engine is off and the compressor is running on battery power alone, the ASU circuitry "sips" power by only running intermittantly for short periods - just enough to maintain the box temperature, without attempting to freeze the cold plate further.
With normal engine operation, the result is a significant 30 to 50% reduction in electrical consumption from your batteries!
These units provide refrigerator or freezer capability with temperatures down to 21°F (-7°C).

• Holding plate can be fitted at any suitable angle high up in the box
• Compressor is small enough to be fitted in stowage compartments within connecting distance from the holding plate
• Water-cooled, self-pumping models include a bronze thru-hull with integral connection fittings and utilize slight motions of the boat to circulate the cooling water
• Extremely quiet operation
• Controlled by special control panel
• Ice cube tray available
• Pre-charged and ready to go
• Easy installation; compressor snaps into pre-mounted base bracket
• Can be mounted on horizontal or vertical surfaces
• Runs on 12V or 24V DC
• An optional Universal AC/DC kit is available for 12/24V DC and 115/230V AC at 50/60Hz is available

Electrical Power Sources
Indel's Isotherm refrigerators feature Secop (formerly Danfoss) compressor units, which come equipped with an electronic control module on rhe side. These modules are rated for either a DC Only power source, or for AC/DC power sources.

DC Only modules run on nominal 12 or 24 volts and have red and black wire leads which connect to the positive and negative terminals of your boat's batteries. A 15A ATC fuse for 12 volt systems (use 7.5A for 24 volts) and an ATC fuse holder are included. If an on/off switch is wired into the circuit, it should be rated for a minimum of 20 Amps.

AC/DC modules run on 12/24 volts DC and include wire leads, as above. They can also run on nominal 100 - 240 volts AC at 50 or 60 Hz. These AC/DC modules have two additional spade-style AC terminals for connecting the included 115 volt AC power cord (which has a two-push-on connectors at the refrigerator end, and a two-prong plug at the power source end).
If you want to run the refrigerator on European 230 volt or US 240 volt systems, you will need to provide your own power cord with a mains power plug which complies with applicable electrical safety regulations.
Note - Due to the double insulated design of the electronic unit, no earth connection is needed.

AC and DC power supplies can be connected to the electronic module at the same time. AC will be the preferred power supply source when both AC and DC power are available.
