1 Preface
Isotherm Classic Compact refrigeration systems are designed and built to provide excellent per-
formance and many years of trouble-free service. The system is pre-charged with environmentally
safe R-134a refrigerant and can be owner installed. This manual has been prepared to provide in-
formation needed for proper installation, operation and maintenance. Before beginning installa-
tion please read it carefully.
2 Installation
2.1 Unpacking and Inspection
Please examine the box and contents for signs of shipping damage. If there is any damage, con-
tact the carrier immediately. All units are shipped with insurance but the carrier must be notified
immediately of any shipping damage in order to process a claim.
Each system consists of:
1. Compressor/condenser unit.
2. Click on mounting bracket.
3. Evaporator with 6 feet of flexible tubing.
4. Thermostat with control wiring.
5. Owners manual and warranty registration card.
2.2 Safety Considerations
Whenever working on the electrical system make certain that all circuits are off before opening
any electrical panels. Disconnect shore power cables and turn battery switches off. Follow
ABYC
standards for electrical installations. If in doubt contact a certified technician.
2.3 Tools and Materials Required
•
Electric drill and bits for pilot holes to attach compressor mounting bracket and evapora-
tor.
•
Wire cutters and electrical terminal crimping tool.
•
Good quality electrical wire of suitable gauge (usually 10/2).
•
Screwdrivers.
•
Wrenches.
2.4 Getting Good Results
Classic Compact refrigeration systems are designed for use in a marine environment and will oper-
ate efficiently for many years with a minimum of maintenance when installed properly. Plan the
installation carefully and choose a suitable location for the refrigerator. The insulation and con-
struction of the refrigerator box are very important and will have a dramatic effect on the per-
formance and power consumption of the refrigerator system.
A box with thicker insulation will require less power to maintain the proper temperature. Three to
four inches of a good quality insulation material with a value of R-5 per inch is recommended.
This will result in a box with an overall insulation value of R-15 to R-20.
The box must be well sealed. Lids must be airtight. Drains (if fitted) must be closed tightly.
Often boxes are pre installed by the manufacturer and modifications are not always easy to make.
If you are planning to build or modify a box please see Appendix A: “Building or Modifying an Ice-
box for Use with an Isotherm Refrigeration System.”
