  • Page 3: Introduction

    Dear Customer! Thank you for choosing the AUTOTERM FLOW heater! We are doing everything to make sure this product meets your requirements. It is essential to us that the quality of our products satisfies every customer. Introduction This manual is intended for organizations that specialize in the installation and maintenance of AUTOTERM FLOW liquid heaters (5D 12V/24V;...

  • Page 4: General Instructions And Operating Principle

    1 General instructions and operating principle AUTOTERM FLOW heaters are designed to be used for: • pre-heating vehicle engines with liquid cooling systems at an ambient air temperature of up to –45°С; • defrosting windshields, heating cabins, cargo compartments, and other confined spaces in vans, trucks, and maritime vessels with a central liquid heating system.

  • Page 5: Safety Precautions

    2 Safety precautions • Do not use or install the heater in places where flammable vapors, gases, or large amounts of dust may accumulate. • Disable the heater when the vehicle or vessel is being fuelled. • Do not cover the heater with clothing, pieces of fabric and so on, and do not place such objects in front of the air intake.
  • Page 6 • In case of faults in the operation of the heater, contact only specialized repair organizations authorized by AUTOTERM. If the consumer fails to follow the requirements above, the warranty of the heater...

  • Page 7: Retrofitting

     Diameter of the exhaust pipe. The FLOW-5D and FLOW-5B have an exhaust pipe with an internal diameter of 24mm, and the FLOW-14D has an exhaust pipe with an internal diameter of 38mm. Some brands use exhaust pipes with different diameters. If so, it needs to be adjusted to a diameter suitable for the heater in use.

  • Page 8: Main Heater Unit And Assembly Installation Requirements

    3 Main heater unit and assembly installation requirements The heater can be installed inside, and outside of the vehicle. Install the heater in a dry place that is protected from water, condensation, dirt, excessive vibrations, heat emissions, engine emissions, and fuel or oil contamination. When installing the heater in a cargo hold of the vehicle, install the heater at a height and location that prevents contact with cargo and in a way that the cargo will not obstruct the air intake for the combustion and exhaust...

  • Page 9: Installation Of The Heater

    When the heater is positioned with the exhaust pipe facing downwards, it is considered the 0° position. FLOW-5D and FLOW-5B have only two mounting positions – 0° and 90° with the air pump pointing upwards. The FLOW-14D should not be tilted (see Fig.1).

  • Page 10: The Installation Of The Coolant System

    When installing the FLOW series heater make sure that the heater is protected from any road spray, dust, water, and moisture. The heater must be fixed properly to bypass any vibrations. It must be installed in a well-ventilated area. DO NOT install near flammable or heat-sensitive objects such as sails, fenders, clothing, sheets, paper, gas pipelines, fuel tanks, etc.
  • Page 11 3.2.1 Installation of the coolant pump The coolant pump must be installed in the cooling circuit upstream of the liquid heater. The coolant pump should be installed below the level of the expansion tank, radiator, and heater. The direction in which the coolant flows in the pump must be the same as in the cooling system of the vehicle/vessel.

  • Page 12: Installation Of The Air Intake Pipe

    3.3 Installation of the air intake pipe. The air for combustion must not be taken from the interior, living space, engine or luggage compartment of the vehicle or vessel. Air should be taken from well-ventilated areas or from outside of the vehicle or vessel. The maximum length of the air intake pipe is 2 meters.
  • Page 13 The air intake must not be installed in the movement direction of the vehicle/vessel. In cases when the intake of clean air cannot be ensured, such as off-road and special purpose vehicles, please mount the dedicated AUTOTERM air filter (assy.2684) 3.3.1 Installation of the air intake pipe on maritime vessels ...

  • Page 15 If the desired mounting situation requires the exhaust silencer to be mounted vertically, the condensation drain hole must be drilled, as shown in Fig. 14b, to avoid the build-up of condensation in the exhaust silencer. If that is not possible, it is recommended to install it sideways (see Silencer Fig.14a).
  • Page 16 If the exhaust pipes of the heater run through the living space or confined space of the vehicle/vessel, solid stainless-steel pipes must be used. Flexible exhaust pipes are only suitable for external use and use in engine rooms. Insulation Fig. 16 – Installation of additional heat insulation The end of the metal hose should not contact the rubber seal of the heater.

  • Page 17: Installation Of The Fuel System

    3.5 Installation of the fuel system. Do not operate the heater using biofuel. Use only diesel fuel standard EN590 and petrol fuel standard EN228, depending on the ambient temperature. Use the instructions detailed in Fig.18 and Fig.21 to install the fuel system. The fuel pump and the fuel supply line must be protected from heating.
  • Page 18 Fuel is taken directly from the fuel tank of the vehicle or vessel, or from an additional tank. Drill a Ø16mm hole in the fuel tank to install a fuel suction hose. When drilling the hole in the fuel tank, follow safety precautions that should be observed when working with any transport, filled operating with fuel or explosive substances.
  • Page 19 3.5.3 Fuel suction from the fuel tank of the vehicle. Fuel is taken from the fuel line of a vehicle using a T-piece (see Fig.21). This method can only be used if there is no pressure in the fuel line. If the vehicle is equipped with a low-pressure fuel pump in the fuel tank, then those fuel lines cannot be used, fuel suction hose must be installed instead.
  • Page 20 If for some reason the fuel pump seal is compromised, it is advised to install the fuel pump lower than the heater to avoid leaks and flooding the heater with fuel due to gravity. Remember to properly bleed the “silent” TH11 fuel pump. If it’s not properly bled it will be as loud as a standard fuel pump.

  • Page 21: Installation Of Heater Wiring

    3.5.5 Installation of the electrical harness of the fuel pump. If the length of the wiring harness of the fuel pump needs to be shortened, it is permissible to remove the unnecessary portion from the middle of the harness. The connection point must be insulated. Never connect the fuel pump to a continuous DC power supply.
  • Page 22 3.6.1 Installation of the relay Relay is sold separately The relay is necessary to connect the FLOW pre-heater to the interior fan of the vehicle. When the coolant set temperature (see operation manual of the control panel) is reached, the relay activates the interior fan of the vehicle. In some cases, the switch of the interior fan of the vehicle must be turned on for this feature to work.

  • Page 23: Installation Of The Control Panel

    3.7 Installation of the control panel. The control panel is intended for the operative control of the heater. Install the panel in a convenient (appropriate) place protected from water. The panel is attached using double- sided adhesive tape or a standard bracket (Fig.29). The wire may be brought out of the panel casing through the back cover or the partition of the inner surface of the panel casing.

  • Page 24: Automatic Control Features

    Before starting to heat the coolant, the pump will start to check if the heating liquid is frozen. The heater will then power up to 100% to heat up the combustion chamber and to provide proper burning temperatures. Depending on the ambient temperature and model of the heater, this process can take up to 15 minutes.

  • Page 25: Recommendations

    If you are unable to find the primary cause of a fault, contact your nearest dealer or service centre, or check the website www.autoterm.com. WARNING! When starting the heater for the first time after installation, it is preferable to fill the main fuel line up to the input nozzle of the heater using a priming device.
