1. Introduction
1.1 General
Isotherm freezers are specially designed to operate in
tough marine environments. They are fi tted with a fully
hermetic, leak-free compressor, they offer the lowest
possible power consumption and noise level. All models
are simple to install. They can withstand an angle of heel
up to 30°, for a short time. To ensure that your Isotherm
fridge operates as effi ciently as possible, please follow
these general guidelines:
• Unnecessary opening of the door will increase
power consumption.
• Good ventilation of the compressor and condenser
unit will reduce power consumption.
• The electrical system should be in good condition.
Inspect batteries and charging levels regularly.
Always use a separate starter battery for the engine.
Follow carefully the guidelines regarding electrical
cable areas and fuse placements.
• Keep the inside of the freezer clean and
dry. Remove any water from condensation that may
have collected inside the freezer.
• Keep the door slightly open to air the freezer
when leaving the boat for any length of time.
• Clean the inside of the freezer with lukewarm
water and a mild detergent before taking the freezer
into operation the fi rst time.
The freezers are equipped with an evaporator placed in
the top and rear of the cabinet.
The DR 55 Freezer INOX has an evaporator unit equipped
with a fan for frost free operation.
The INOX models have a more exclusive door in stain-
less steel and they also have a fl ush mounting frame for a
smooth fl at mounting on board. The doors have a stainless
steel door lock of a more rigid type and are also equipped
with interior trims in stainless steel.
The DR 55 Freezer INOX has the door made as a drawer
instead, lower drawer box and door is built together. It has
also an upper separate drawer.
