Notes for using Truck Air Conditioner

 

In using truck air conditioner, please follow the instructions as below:

 

To set the air-conditioning temperature within a suitable range. Low temperature not only easily causes physical discomfort, but also increases energy consumption.

 

To choose proper operation mode: Truck air conditioners are with eco mode, sleep mode and strong mode. Clients can choose the appropriate mode according to their needs.

 

Error codes definition, faults, and solutions

 

Error code flash on internal machine:

While using the air conditioner, if the following codes display on the screen, they may indicate relevant faults of the machine. Please make the following operations:

Stop the air conditioner and make it power off. After ten minutes, power on and start it. If the code is still there , stop the machine and power it off,and then contact the repair center. (If the code disappears, you can continue to use it)

E01--Voltage is too low - Please charge the battery

E02--Evaporation box fan’s power circulation is open--Please check the fan’s plug or replace the fan

H22-- Air inlet sensor failure indicates that the mode can be changed after returning to normal

H23--Out inlet sensor failure indicates that the mode can be changed after returning to normal

E04--Pipe temperature (outlet air) sensor

E05--Compressor overheat ---After the compressor cools down,automatically resume working

E06 --Condensing fan open circuit 一 Check if the circuit from compressor to condenser fan is open circuited

E07--Condensation fan short circuit --- Check if circuit from compressor to condenser fan is short circuited.

E09--The brushless control board of the condensing fan fails--please replace the control board of the condenser fan

E10--Condensing fan failure -- Please replace the condensing fan motor

E11 The condensing fan is out of contact ---- Please check the compressor control board and the condenser fan wiring for damage

 

LED light flashing times indicates the compressor faults:

The LED light is located at the end of the compressor

Flash 1 time -- Standby

Flash 5 times -- Compressor case temperature is too high

- Lack of refrigerant or dirty condenser

Flash 6 times - Open circuit of cooling fan- Bad contact of electromagnetic fan plug

Flash 7 times - Short circuit of cooling fan--

Short circuit in the motor or short circuit in the connection line

Flash 9 times - Condenser fan controller failure

Flash 10 times - Condenser fan failure

Flash 11 times - Condenser fan lost contact

Note: If the according flashings of the compressor doesn’t exist in the table above, please replace the compressor control panel

 

Other Faults

In any of the following situations in using of the air conditioner, please find out a solution by following the index; if it is a fault, please contact the repair center.

 

Phenomenon

Solution

The refrigeration effect is not good

Select the right mode and set proper temperature and speed

Check if there is any obstruction at the air inlet and outlet

Check if the surface of the condenser is too dirty

Check if it is short of refrigerant, and if he high and low voltage is within the normal range

There is water on the surface of indoor unit

When running in an environment with high humidity, water drops will form at the air outlet and core surface, which is a normal physical phenomenon

The indoor unit displays voltage fault

Check if it is battery low and if the power source is DC24V

Check if the low voltage protection value is too high

The indoor unit displays sensor fault

Check if the sensor at air inlet/outlet is plugged in correctly

Check if the display temperature is higher than normal ambient temperature. If it is, change the sensor

The indoor unit displays fan fault

Check if the fan is correctly plugged in. Connect the fan with a separate 24V DC power source. If the fan won’t work, change it

The indoor unit displays outdoor unit fault

Check if it is short of refrigerant

Check if the high and low voltage is within the normal range

Check if the condenser is too dirty that heat dissipation is adversely affected.

 

Truck Air Conditioner Installation Instructions

 

Step 1: Remove the original skylight

Step 2: Fix the water proof sponge along the skylight

Step 3: Fix the parking air conditioning main body on the skylight

Step 4: Install the decorative cove of air conditioner and fix with screw

Step 5: Connect power cable to vehicle battery directly. Pay attention to batter’s positive and negative

Step 6: Start the paring air conditioner with remote control

 

Notes and fault analysis for installation

The red positive electrode (≥10mm2) shall be connected to the positive electrode of the battery (the end with fuse shall be connected to the positive electrode of the battery), and the negative electrode shall be connected to the negative electrode of the battery.

The sponge around the sunroof shall be flat without wrinkles to avoid water leakage after installation of the air conditioner.

 

Fault analysis for refrigeration failure or bad effect

A. The power cord is too long and thin, with bad connection

B. No or short of refrigerant

C. In energy-saving mode

D. The fan of compressor or condenser doesn’t work

E. The evaporator or condenser is too dirty or blocked

 

Turn on the dc air conditioner and check if the high and low pressure is within the normal range {high pressure: 1.2-1.4, low pressure: 0.2-0.25). Select a mode and see if the air conditioner can work normally under all modes. After the air conditioner can run normally, turn it off dc air conditioner

 

Rooftop Air Conditioner R3

 

Attention: Refrigerant oil is filled in the Dc Air Conditioner before delivery. After first time installation, do not fill more refrigerant. In case of any refrigerant leakage in using the dc air conditioner, add 80ml refrigerant oil POE68 again. The refrigerant oil must be of high quality.

 

How to maintain dc air conditioner?

 

Before cleaning it, make sure the air conditioner is turned off, powered off and unplugged.

* To clean indoor unit evaporator surface:

Wash the cleaning cloth in clean water, dry it and wipe the surface of the unit. The cloth can be dipped in the water solution of neutral cleaner.

* To clean the core of evaporation tank:

Remove the indoor unit case and blow off the dust on the surface with compressed air.

* To clean outdoor unit:

Remove the unit case and clean the condenser with compressed air. Avoid any bump against the condenser.

If you don’t use the parking air conditioner for a long time, unplug the air conditioner and wrap the outdoor unit and avoid any bump

* To use the dc air conditioner after long-time storage:

Clean the unit body, condenser, and evaporation unit; check if there is foreign matter at the air inlet/outlet of the indoor and outdoor unit; check if the drain pipe is clear; put batteries in the remote control; make inspection and power it on.

 

Tips:

Clean the dc air conditioner once every month. If there is too much dust in the working environment, increase the cleaning frequency accordingly. Please make regular cleaning to make sure it can run normally.
