Introduction This installation manual was written to help assist with the installation of Thermo King refrigeration units powered by vehicle batteries onto either a truck or a van. The manual comprises sections on condenser, evaporator and other modules that are mounted on the truck or van body, as well as sections on components and wiring that are to be connected to the vehicle engine from which the unit derives power.
Safety Precautions DANGER: When removing a battery from the Battery Pack, symbol appears next to a point that is particularly important. ALWAYS disconnect the negative battery terminal first. Then remove the positive terminal. When reconnecting the battery DANGER: Addresses a circumstance that, if encountered, will lead terminals, connect the positive terminal (+) first, and connect the to death or serious injury.

Safety Precautions (continued) Refrigerant WARNING: When using ladders to install or service refrigeration systems, always observe the ladder manufacturer’s safety labels and WARNING: Although fluorocarbon refrigerants are classified as safe warnings. A work platform is the recommended method for refrigerants, certain precautions must be observed when handling them installations.

RECOVERY OF REFRIGERANT At Thermo King, we recognise the need to preserve the environment and limit the potential harm to the ozone layer that can result from allowing refrigerant to escape into the atmosphere. We strictly adhere to a policy that promotes the recovery and limits the loss of refrigerant into the atmosphere.

2. Pass two clips of appropriate diameter over the hose. 3. Lubricate the cylinder of the fitting to be inserted in the hose, using Thermo King refrigerant oil. 4. Manually insert the fitting into the hose. The hose should touch the projecting part of the fitting without going into it.
Connecting Hoses to the Condenser Unit 1. Take the plugs off all the tubes. 2. Lubricate all refrigeration intakes with Thermo King refrigerant oil. 3. Place an O-ring on each refrigeration intake. 4. Check that the O-ring is properly positioned and connect each hose using two fixed wrenches.

Drain Circuit in the ES100 Evaporator 1. Cut the drain hose to the required length. 2. Connect the hose to the drain tube. Secure connections with plastic flanges. 3. Route the hose through the drain hole and seal hermetically. 4. Check that the corresponding siphon or moisture trap is installed at the end of each drain hose.

Circuit Seal Test 1. Heat the box up to +20ºC/+70ºF using a ventilated radiator. 2. Connect the gauge manifold to the suction 1 and discharge 2 intakes of the condenser unit. 3. Connect the central line of the gauge manifold to the vacuum pump. Use recommended vacuum equipment.
In Case of Leaks 1. Pressurize the circuit to 17 bar / 250 psig with nitrogen. 2. Identify the defective part (fitting, sleeve, line, hose, O-ring, etc.) and replace it with a new part (if in doubt replace the entire joint). Use the recommended leak detector.
3. Mount the base of the mounting bracket in the chosen location. Use screws (C), rubber mat (D) and metal plate (E), which are supplied by Thermo King, as indicated in the drawing. 4. When placing the in-cab control box on the bracket, rest the in-cab control box on the arm (F), and slide it to the right until the arm tab is properly fitted to the in-cab control box frame.
Optional Internal DIN Adaptor 1. Place the metal box (J) supplied in the housing designed for the radio. Raise the tabs (M) sufficiently to fit the box into the housing. 2. Attach the control to the plastic bracket (L) using the 4 screws (K). 3.
Control Cable Connection 1. Pass cable 01 of the electrical hose through to the cab. 2. Locate the fuse box. 3. Connect wire 01 to the vehicle’s fused ignition circuit. NOTE: Use a splice capable of supporting a 3A electrical current.
5. Connect wire 2 to one end of the fuse FP fuse holder (both supplied by Thermo King) and connect the other end of the fuse holder to the battery's positive pole. Install fuse FP (100A/12V or 60A/24V) in the fuse holder.
Fitting the Power Supply Units with Electric Standby WARNING: Always confirm the supply voltage matches the voltage specifications of your particular unit prior to making any electrical connections. 1. Install the power supply housing in a protected and accessible location. 2.
