Multi-temperature unit only.
If the cab command is built into the vehicle control panel it must be located as far as possible from the heating ducts. Maximum temperature of exposure: 70°C (150°F).
4.2. OPERATION PRINCIPLE
4.2.1. POWER SOURCE
4.2.1.1. IN “ROAD” MODE
PULSOR ® units are equipped with the E-Drive all electric system, which removes mechanical transmissions found in belt-driven refrigeration systems and transforms engine power into electricity through a generator.
The generator is driven by the vehicle’s batteries and supplies voltage to an inverter, which distributes it to the various components of the unit.
The unit automatically starts or stops when the vehicle’s engine is switched on or off using the ignition switch.
4.2.1.2. IN “STANDBY” MODE
PULSOR ® units can operate when the vehicle is docked by plugging it into the mains.
The power connection is automatically detected by the unit, which starts in “Standby” mode after pressing the ON key.
4.2.2. OPERATING MODES
4.2.2.1. CONTROLLED TEMPERATURE (COOLING & HEATING)
As soon as the setpoint temperature has been reached, the temperature control is achieved by the start-up and shut down of the compressor.
The evaporator(s) fan(s) are programmed to stop during regulation.
When transporting fragile loads such as fresh meat, vegetables and cheese, it is possible to program the microprocessor to obtain continuous ventilation by the evaporator during regulation.
To activate or deactivate the function, please refer to the Section 5.8, “Set user function” > “Effort” function.
4.2.2.2. DEFROST
Frost gradually builds up on the evaporator coils during normal operation.
The evaporator coil is defrosted by sending hot gas through the coil (or by using optional electric heater(s)).
Defrost operation is fully automatic from start to finish but, can be manually initiated if required.
For further information, please refer to the Section 5.4, “Start a manual defrost mode”.
The start-up parameters can also be changed from automatic to fixed interval. Please refer to the Section 5.8, “Set user function”.

4.2.2.3. EUTECTIC SPECIFICITIES® PULSOR
units can be equipped with eutectic plates in addition to an evaporator in order to reach deep-frozen temperatures. Theses units require special care in order to work properly: – Deep-frozen temperature require extra time to be reached, therefore, units must be started well before your drive (e.g. the night before) to reach the desired temperature.
– Frost gradually builds up on the eutectic plates. Unlike a regular evaporator, the defrost sequence is not automatic, but is still crucial for proper operation, which is why the unit must be defrosted manually on a regular basis.
For further information, please refer to the Section 5.6, “Defrost the eutectic compartment”.
The eutectic compartment is locked at -40°C (-40°F) and its set point cannot be changed.

OPERATION

5.1. START THE UNIT
Power source selection is fully automatic. This is why there is no button to select the desired mode. A soon as one operating mode is disabled, the unit automatically starts up in the other mode.
If the vehicle’s ignition is switched on while the PULSOR® unit is connected to the mains (“Standby” mode) or if the power plug is connected while the vehicle’s engine is running (“Road” mode), the cab command unit will trigger a visual alarm, in the form of a flashing red malfunction indicator light and a A035 code.
As soon as one operating mode is disabled, the unit automatically starts up in the other mode and returns to normal functioning.

5.1.1. “ROAD” MODE

Switch on the vehicle’s ignition.
Press the ON key to start the unit.*
After a prolonged shutdown in cold weather, the compressor needs to warm up.
During this sequence, the unit displays “CPHT” for 3 to 12 minutes (the duration varies according to the ambient temperature).
DO NOT SWITCH OFF while “CPHT” is displayed.
The setpoint will be highlighted for 5 seconds, followed by the actual box temperature.

Once you have started the unit at the beginning of your drive, the following start and stop sequences are performed automatically by the vehicle’s ignition system.

5.1.2. “STANDBY” MODE
For safe & reliable operation in “Standby” mode, it is important to consider the following guidelines:
A. ALWAYS check that the unit is OFF from the cab command before connecting or disconnecting it from the mains.
B. The unit connection cable must be fitted with a ground connection. The cable must be connected to earth.
C. On the 230V / 400V power supply, the unit must be connected to a high sensitivity differential protection (30 mA).
D. Operations on the 230V / 400V power supply to the unit must only be carried out by authorized personnel.
THE USER IS RESPONSIBLE FOR ENSURING THAT THE ABOVE MEASURES ARE TAKEN AND COMPLIED WITH.

MAINTENANCE

8.1. INTRODUCTION
A comprehensive maintenance program ensures that the unit continues to operate reliably. Such a maintenance program will also help to control operating costs, increase the unit’s working life, and improve performance.
IMPORTANT TO READ AND FOLLOW
Regular maintenance includes a quick overview of the unit from a safety perspective. Service Technician must pay particular attention, but not exclusively to: nuts and bolts tightening (replacing if missing), electrical wires, harnesses, fuel lines routing (repairing or replacing if needed), doors, skins grills, panels conditions (repairing or replacing if needed).
Confirmation of such operations can be detailed on request.
All maintenance services must be done by a technician trained on Carrier Transicold products, respecting all safety and quality standards of Carrier Transicold.
8.2. WARNING STICKERS MAINTENANCE

Keep the warning pictograms clean and without any obstruction material.
Clean the pictograms with water and soap and wipe them with soft fabric.
Replace damaged or missing pictograms with new pictograms available from the Carrier Transicold network.
If a component bearing a pictogram is replaced by a new one, make sure that the new component has the correct pictogram.

RECOMMENDATION

9.1. BEFORE LOADING

DEFROST Properly defrost your transport refrigeration unit.
CLEAN THE EQUIPMENT Especially the interior: walls, roof and floor.
When washing the vehicle, DO NOT point the high-pressure water under the skin.
DO NOT spray water on electric components.
Units charged with low GWP refrigerant are equipped with refrigerant detectors that are located in the evaporator section (these detectors are identified by a sticker).
Pay special attention to these electrical detectors when cleaning, DO NOT spray water on them.
When washing the interior, DO NOT spray the fan with detergent.
PARTIAL LOADING Use movable bulkheads to limit compartment size in case of partial loading.
STRIP CURTAINS To limit the flow of cold air to the outside, use strip curtains and make sure they are not too old and with a proper length down to the floor. PRE-COOL THE BODY When possible, pre-cool the body on standby mode to reduce noise and CO2 emissions. Do not leave the vehicle unattended during pre-cooling.
GOODS TEMPERATURE Goods must be at the right temperature before loading.
9.2. DURING LOADING

RESPECT CORRECT TEMPERATURE Products should always be loaded from a refrigerated loading bay in order to maintain the correct temperatures. The setpoint doesn’t need to be at -26°C if only -18°C are required.
SEPARATE GOODS Do not mix refrigerated and dry goods in the same compartment. The second compartment cannot be cooled by a fan from the first compartment for hygiene reason.
TEMPERATURE CONTROL Perform load tests with the right materials to ensure the products are loaded in at the optimal temperature. Do not obstruct the evaporator with the loaded goods. Make sure that air circulation is not impeded. Properly orientating the pallets allows the airflow to reach above, through and underneath the load. Do not load up to the ceiling, as this will cause short cycling.

DETECTORS CLEARANCE Units charged with low GWP refrigerant are equipped with refrigerant detector that are located in the evaporator section (these detectors are identified by a sticker). Pay special attention to these detectors. At no time should their access be blocked. Ensure proper airflow to these detectors.
9.3. AFTER LOADING

SHUT DOWN UNIT WHEN OPENING DOORS Cold air is heavier than hot air. Opening doors with no curtains leads warmer air to replace cooler air. Operating the unit when doors are opened may result in frost and increase energy consumption. Carrier also offers door switches to shut down the unit automatically when loading the van, which reduces the warm air penetration into the box.
KEEPING DOORS CLOSED Keep doors closed as long as possible. WAITING TIME Minimize the wait time during which the goods are on the loading dock.

PARKING Park the vehicle in the shade. Do not park your vehicle in a slope greater than 10% to avoid poor water drainage.
UNIT STORAGE In the event of a prolonged shutdown, open the doors and compartments of the refrigerated box. Never leave your unit more than a month without running.
AIR RENEWAL Units charged with low GWP refrigerant should operate for at least one hour once a month with the refrigerated box doors and compartments open.
