Making A Cut-Out In The Floor - Truma S 3004 Installation Instructions Manual

Installation
2.4.1 Water supply
If a water supply is being installed in the vehicle, it must
be ensured that sufficient room is left between the
water hoses and the heat source (e�g� heater, warm air
duct)�
A water hose may only be routed at a distance of
1�5 m from the heater at the warm air duct� With lead-
through, a spacer (e�g� insulation) must be fitted in
order to avoid contact� The Truma hose clip SC can be
used for distances greater than 1�5 m�
2.4.2 False floors
If a perforated drawer is installed over the heater that
is used for drying objects, for example, an intermediate
shelf made from non-coated wood must be installed�
The covers of the mounting frame must be made from
temperature-resistant material� Do not use PVC or simi-
lar material�
The minimum depth l₁ and minimum height l₂ (Fig� 4)
must be observed�

2.4.3 Underfloor protection
If the vehicle floor is being coated with underfloor pro-
tection, all heater parts located beneath the vehicle
must be covered so that the resulting spray mist does
not cause heater system malfunctions� Remove covers
again when the work is complete�

Making a cut-out in the floor

The bottom edges of the installation box and the heater
base must be on the same plane so that the control knob
is not too high or too low in the support�
For problem-free and safe operation, it is important
for the heater to be positioned in accordance with the
enclosed installation template� The figures show the
template for the S 3004 by way of example� Use the
corresponding template for installing the S 5004�

Using the installation template, check whether the
floor cut-out for the combustion air intake should be
on the left or the right�
R = Right-hand installation (Fig� 5)
L = Left-hand installation (Fig� 6)
Attach the installation template to the floor of the
installation cut-out for the installation box using ad-
hesive tape� The side arrows must point exactly to
the leading edge of the cut-out�

Check the area around the planned cut-out in or
beneath the floor to make sure there are no supply
lines (gas, diesel, electricity, water pipelines, etc�)
or chassis parts (wheel arch, crossmembers, brake
lines, water tanks, etc�)� Change the planned instal-
lation location if necessary, move lines or remove
l
obstacles�
Check the position of the roof cowl and the length
of the cowl pipe� See the Chapter "Installing the
roof cowl" and change the installation position if
necessary�
Use a graver to prepare the 5 points for the fasten-
ing screws (R or L)�
Transfer the corner points of the rectangular cut-out
to the floor using a graver�
Remove the template�
Transfer the rectangular cut-out to the floor� To do
this, use a pencil and ruler to connect the insertion
points to the corner points of the cut-out�
Saw out the floor cut-out as precisely as possible�
Do not saw out too large an area so that the frame
halves can be screwed down into the floor later�
Seal interfaces to prevent moisture penetration and
allow them to dry completely� Do not use flammable
or heat-sensitive materials for the seal�
Pretension the frame halves (Fig� 7-1) by bending
open the legs so that the frame sits properly in the
floor cut-out�
Insert the frame halves (Fig� 7-1) into the floor cut-
out (Fig� 7-3)� The frame legs overlap slightly�
