SAFETY Safety Alerts Throughout this manual, you will see notes labeled 'Warnings' or 'Cautions' to alert you to special instructions or precautions concerning a particular procedure that would be hazardous if performed incorrectly or carelessly.
Observe them carefully! These safety alerts alone cannot eliminate hazards that can occur.
Strict compliance with these special instructions when performing the installation and maintenance, plus common sense, are major accident prevention measures. Safety Considerations Exhaust Inhalation of exhaust gas (containing carbon monoxide) may cause severe personal injury and/or death. Anyone suspected of suffering from CO inhalation should be removed from the hazardous area and given medical assistance immediately.

NOTICE When visible, the A/C is cooling.
The DCP (driver control panel), which 3 Indicates the number of operating hours on the APU. 1.1.2 How the ComfortPro Operates The ComfortPro has two modes of operation: manual and automatic. Manual Mode You start the APU from within the truck bunk using the On/Off button on the driver control panel (DCP).
Once the APU is running, you can start and stop the fan, heater and air conditioning using the DCP. Automatic Mode and Minimum Time Off All these automatic functions work on a 'minimum time off': the ComfortPro must be off for at least 10 minutes before the automatic function will turn it on again.
For example, the Timer function may be set to turn on the ComfortPro at 10:00 a.m. 1.2.3 Turning the Heater ON/OFF 1 Press to activate the heater.
NOTICE HOURS 00000 The display shows 'HEAT LOW'. The heat mode will not function if the temperature is higher than 85°F. The heater will turn on only if the HEAT LOW temperature is too low (to adjust the temperature, see below). 1.2.7 Fan Operation You can still have the fan working even when the temperature is not low or high enough for the heat or A/C to come on. The fan operation is independent of the air conditioning and heat modes. When the fan speed is manually set to high or low, the fan will return to that setting when the desired temperature has been reached as the air conditioning or heat cycles off. 3 Press until the first number in the password is displayed.
For example, if your password is '432' press until '4' shows, then press 4 Repeat for each digit in the password. 5 Press again after entering the last digit.
'NEW PASSWORD' is displayed. 1.3.3 Setting the Clock You can set the clock on the DCP.
This clock is used by the Timer function (page 1-8). If you use the Timer function, remember that as you move from one time zone to another, you must adjust the clock. Otherwise the Timer will start the APU at the wrong time. Setting the TEMPERATURE 1 Press NOTICE HOURS 00000 Factory Default Temperature Setting is 2 Press until 21°C / 70°F.
Range is 18°C / 64°F to COMFORT MONITOR 'COMFORT MONITOR' is displayed, 30°C / 86°F. Then press If 'ENTER PASSWORD' is displayed, enter your password. If you do not know the password, then you cannot set up this function (see page 1-5). Setting the Start Time/Day 1 Press HOURS 00000 2 Press until TIMER 1 'TIMER 1' or 'TIMER 2' is displayed, SET START then press If 'ENTER PASSWORD' is displayed, enter your password. If you do not know the password, then you cannot set up this function (see page 1-5). 3 Press to display 'SET START'. 1.3.6 Cold Weather Watch You can set up the APU so that it automatically runs for a specified time whenever the ambient temperature goes below a specified value.
This feature ensures that the APU engine and truck engine do not get so cold that they will not start. Setting the DURATION HOURS 1 Press 00000 NOTICE 2 Press until TEMP START Factory Default Duration Setting is 2 'TEMP START' is displayed, then SET DURATION hours. Range is 1 hr to 4 hrs.
Press If 'ENTER PASSWORD' is displayed, enter your password. If you do not know the password, then you cannot set up this function (see page 1-5). 1.3.8 Battery Monitoring You can set up the APU so that it automatically runs for 90 minutes when the truck batteries are low. When you set up this feature, you must enter the current voltage of the batteries (see “Set the Initial Voltage”). The ComfortPro can then calculate how much the voltage drops, as the batteries are used.
CLIMATE CONTROL UNIT (CCU) PREPARATION 2.1.1 Charging the CCU WARNING Pressure test the system for leaks with nitrogen. This procedure must be performed by a certified air conditioning technician Vacuum all the nitrogen for a minimum of 30 minutes to 500 microns.

3.8 TESTING PROCEDURES 3.8.1 Testing AMP draw for components When checking functions of individual components, place amp clamp over black (power) wire coming in from the generator to the CCU board. (As shown in below.) When cross-referenced with the “AMP DRAW AND VOLTAGE CHART”, the components should show the same amp readings. 3.9 ADDITIONAL INFORMATION 3.9.1 Adjusting the 120 AC Voltage This does not need to be adjusted under normal operation. If you find low AC voltage, check the generator belt, air filter, fuel filters and exhaust system before adjusting. With the APU running turn all 120-volt components off.
Measuring the voltage at the outlet panel adjust the engine speed until 120 (+/- 10) volts AC and 60 Hz +/- 2 Hz is read. 3.9.4 Potential Relay Theory In a Capacitor Start, Capacitor Run compressor the start capacitor is only designed for momentary use. The Potential Relay (NC) is used to connect and disconnect the start capacitor from the compressors start windings. Induced Voltage is generated in the start winding when of the compressor when it is running.

CCU CONTROLLER Inputs AC – This is the input from the Driver Control Panel only when it is calling for Air conditioning. (Low or High A/C.) HEAT – This is the input from the Driver Control Panel only when it is calling for Heat. FUEL SYSTEM PURGE PROCEDURE 1. Start the APU with the APU Test Switch Module. If APU fails to start, crank in 15 second bursts until fuel system is purged of air and APU starts and runs smoothly. OPEN TO BLEED THE FUEL SYSTEM FUEL FILTER Figure A-6: Fuel Filter. COOLANT PURGE PROCEDURE Ensure that the coolant supply valve to the APU (located at the truck engine) and the coolant return valve to the APU (also located at the truck engine) are open.
Release pressure from coolant system. Remove the truck engine radiator cap. Top up the coolant if necessary in the expansion tank. Start the APU by following the instructions on page 1- 3 (Multi-Function Driver Control Panel).
With the APU and truck engines running, open the thermostat bleed valve and let any trapped air escape until a steady stream of coolant flows from the valve. Shut the truck engine off.
