When the external heating air duct is connected to the heater, the duct diameter should not be less than 85 mm. The material of the cable should be resistant to a temperature of 130^ C. The maximum pressure drop between the inlet and outlet sides of the air heating system should not be greater than 0.151 kPa.

Hot air from the heating system should not flow to parts that are not heat resistant. In passenger vehicles, the vent should not be obstructed by passengers. If necessary, you can install a protective net on your own. In the case of the heater operating in external circulation mode, the position of the air inlet opening should be appropriate to ensure that no water splashes or exhaust fumes are sucked into the heater during normal operation.

In the case of the heater operating in the internal circuit, measures must be taken to prevent the supply of hot air from re-entering the air inlet port. If the air inlet pipe is not connected in this mode, a hood with grilles should be installed on the air inlet port of the main heater. The intake air should be taken from a cold area of the compartment, e.g. from under the seats.

Fuel supply

The fuel for the heater can be supplied from the vehicle's fuel tank or from an additional, independent fuel tank. Do not install the fuel tank in the cabin or passenger compartment or in any other place that may cause a fire if an independent fuel tank is used.

The difference in height between the heater and the fuel pump and between the fuel pump and the heater creates fuel pressure in the fuel pump. The inner diameter and length of the fuel line are related to the resistance in the fuel path. Take these factors into account when installing.

max 3m I2 H I1 I2 I1

I_1 + I_2 ≤ 10m
I_1 ≤ 1.2m
I_2 ≤ 8.8m

Installation of the fuel pump - applies to MSW-DPH-01 / MSW-DPH-03

The fuel pump should be installed in places where it is possible to avoid thermal radiation from parts of the vehicle that may emit heat and in places with cool air. Instructions for installing the fuel pump are shown in the figure below. When installing the fuel pump, use the fuel pump bracket supplied with the heater to hold the pump firmly. The pump is secured with a shock-reducing clamp. The place of installation of the pump must be close to the fuel tank so that the fuel suction line is as short as possible. The place of installation must be protected against stone chipping.

Installing the fuel filter

The fuel filter should be installed upstream of the fuel inlet port. Make sure the fuel flow is correct. Its position should be as shown in the figure above.

Installation of the fuel line

Use only steel and plastic hoses made of light- and heat-resistant plastic in accordance with the requirements of DIN 73378 as fuel lines. The inner diameter of the cable is 2 mm.

The fuel line should be located away from flying stones and parts of the vehicle that emit heat. If necessary, the protective device can be locked.

The fuel line from the fuel pump to the primary heater should be oriented in any direction other than downward. The fuel line should be tied in a suitable place to keep it stationary. The distance between the two ties should be less than 50 cm.

The fuel line fittings supplied with the heater should be used for the connections between the fuel line and the fuel pump, the fuel line and the heater, the fuel line and the suction line of the fuel tank, and the fuel line and reducer. The fuel line should be tied with the fuel line clamps. Air bubbles should be removed from the connection points.

Installation of the combustion air intake pipe and the gas discharge pipe

The combustion air must be drawn in as fresh air from the outside of the vehicle. The exhaust gases from the combustion process must be discharged into the air through the exhaust pipe. Measures must be taken to prevent exhaust gases from entering the vehicle again.

The cables pass through the outer wall or openings at the bottom of the vehicle. Measures must be taken to prevent the ingress of water splashes. The cables must be secured and permanently shockproof.

Only the air inlet hose and the exhaust hose supplied with the heater may be used. The air intake pipe is a corrugated pipe made of aluminium pipe, the surface of which is covered with plastic and paper. The exhaust pipe is a corrugated stainless steel pipe. You need to identify them and not make a mistake during installation.

To connect them to the heater, use the provided clamps to securely attach them to the combustion air inlet and the exhaust pipe vent, respectively. The protective hood on the air inlet and exhaust outlet openings must be kept in good condition. It must not be damaged or removed.

Both the air inlet pipe and the outlet pipe should extend downwards from the heater, otherwise prepare a hole at the bottom of the pipe to drain the condensation water if the pipe needs to be bent.
