5. Operation
5.1. Responsible Operation
Responsibility for freezer operation should be part of the policy and procedure
documentation or guidelines for the Freezer usage. Safety requirements are
integral to these responsibilities, use this product only in the way described in
the product literature and in this manual. Before using it, verify that this product
is suitable for its intended use. If this equipment is used in a manner not
specified by the manufacturer, the protection provided by the equipment may be
impaired.
Important changes to the freezer settings require sustained button pushes, this
helps prevent accidental changes to the settings during transportation.
Turning the Freezer ON/OFF requires a Touch on the Power button. The default
display is the cooling temperature of Freezer, other displays such as Set-point,
ambient temperature, machine hot side temperature etc., are tagged with such
names and described in detail in the UI guideline section.
Operation for the AC and DC system is described in the section 4, operation in
vehicle DC system need extra precautions to avoid any incidents.
Notes on operation in a vehicle:
1. Connect cigarette lighter plug to vehicle after starting the engine.
2. The vehicle engine should be running during the operation of Freezer to
prevent accidental discharge of the battery.
3. Do not operate the Freezer in an unattended vehicle. This may lead to
overheating if left in the sun and subsequent damage to stored contents.
Disconnecting from power:
1) Turn OFF the Freezer (Press Power button on UI)
2) The Freezer will give beep sound while the unit turns off.
3) Turn OFF the switch and unplug adaptor cable from the Freezer after 30
sec of beep if battery is fully charged.
4) Do the same while using the freezer in the vehicle.
5) If you unplug the Freezer while it is on, you will hear a sudden noise as the
free-piston Stirling engine power is switched from main power supply to
battery and will cause the noise. This noise (described as a “bonk”) is not
indicative of damage.
