The Truck

The 20ft Used Standard Refrigerated ISO Container is delivered using a 30 ft tilt bed truck. This delivery method requires 30 ft plus 20 ft the length of the container, so 50 ft in total.

Door Location

When placing your order, know the direction you want the container doors to face at your location. This determines whether we load the container "doors to the cab" or "doors to the rear" of the truck. On delivery day, our driver will back up to the location you’ve chosen and slide the container onto the ground.

Prepare the ground

Tilt bed trucks and trailers are heavy! In order for them not to get stuck, the ground needs to be compact and dry leading up to the drop location. Muddy roads are not suitable for a tilt bed truck, or pickup truck with tilt bed trailer to drive on. The driver will also need 30 ft of width for any turns they may need to make. If your location is already dry, compact, and level then you’re ready to go. If not, a common solution is laying down gravel, cement or pavement. To ensure the container is level, support all four corners with wood blocks.

Remove any obstructions

In addition to the container drop location, make sure to prepare the entire delivery site for the driver. Remove any obstacles in the way that would prevent the truck from reaching the delivery location. This includes low hanging tree branches, low power lines, overhangs etc. If there are any obstacles or issues you would like to bring to our attention please don’t hesitate to reach out to the Conexwest dispatch team.

37AL59 Heater Termination Thermostat (HTT)Heat Termination Thermostat (HTT) is open.Alarm 59 is trig- gered by the open- ing of the Heat Ter- mination Thermo- stat (HTT) and will result in the disab- ling of the heater.Check for 24 volts at test point TP10, if no voltage at TP10 after unit has reached set point HTT is open.Replace HTT if defective.
38AL60 Defrost Temperature Sensor (DTS)Failure of the Defrost Temperature Sensor (DTS) to open.Defrost Temperature Sensor (DTS)Test the DTS; refer to Sensor Checkout Proced- ure Section 6.24.1.Replace the DTS if defective, refer to Sensor Replacement Section 6.24.2.
39AL61 Heater Current Draw FaultImproper current draw during heat or defrost mode.Heater(s)While in heat or defrost mode, check for proper current draw at heater contactors, refer to ELECTRICAL DATA Section 2.3.Replace heater(s) if defective, refer to Section 6.15.2 Evaporator Heater Removal and Replacement.
40ContactorCheck voltage at heater contactor on the heater side. If no voltage present:Replace heater contact- or if defective.  
41AL63 Current LimitUnit operating above current limit.Refrigeration SystemCheck unit for air flow restrictions.Clean or remove any debris from coils.
42Check unit for proper operation.Repair as needed.   
43Power supplyConfirm supply voltage/fre- quency is within specifica- tion and balanced accord- ing to ELECTRICAL DATA Section 2.3.Correct power supply.  
44Current limit set too low.Check current limit setting Code Cd32.The current limit can be raised (maximum of 23 amps) using Cd32.  
45AL64 Discharge Temperature Sensor (CPDS)Discharge Temperature sensor out of range.Discharge temperature sensor (CPDS).Test the CPDS; refer to TEMPERATURE SENSOR Service Section 6.24..Replace the CPDS if defective, refer to TEMPERATURE SENSOR Service Sec- tion 6.24.
46AL65 Discharge Pressure Transducer (DPT)Compressor Discharge Transducer is out of range.Compressor Discharge Transducer (DPT)Confirm accurate DPT pressure readings, refer to MANIFOLD GAUGE SET Section 6.2.Replace DPT if defective.
47AL66 (SPT) Suction Pressure Transducer, (EPT) Evaporator Pressure TransducerSuction Pressure Transducer (SPT) out of range.Suction Pressure Transducer (SPT)Confirm accurate EPT and SPT pressure readings, refer to MANIFOLD GAUGE SET Section 6.2. Performing a Pre−trip 5−9 test will also check the transducers.Replace EPT/SPT if defective.
48MonitorIf the alarm persists, it may indicate a failing compressor, refer to COMPRESSOR Service Section 6.8.   
49AL67 Humidity SensorHumidity Sensor (HS) reading out of range.Humidity Sensor (HS)Make sure the humidity sensor is properly connec- ted in the socket and the wires have not been dam- aged.Monitor, replace HS if alarm persists.
50AL68 CPC Pressure Sensor (PS3)Condenser Pressure Transducer (CPC) out of range.Condenser Pres- sure Transducer (CPC)NAUnit will disable Con- denser Pressure Control if Configured.
51AL69 Suction Temp Sensor (CPSS)Suction Temperature Sensor (CPSS) out of range.Suction Temperature Sensor (CPSS)Test the CPSS, refer to TEMPERATURE SENSOR Service Section 6.24.Replace CPSS if defective, refer to TEMPERATURE SENSOR Service Section 6.24.
52AL70 Secondary Supply Sensor (SRS)Secondary Supply Sensor (SRS) is out of range.Secondary Supply Sensor (SRS)Perform Pre−trip P5:If P5 passes, no further action is required.
53If P5 fails, replace the defective sensor as determined by P5, refer to TEMPERATURE SENSOR Service Section 6.24.
