Boiler transport

Boiler transport

The R40 ECO is a fully equipped 

compact heating system, which has 

been pre-set and tested at the factory.

The dimensions of the packaging are:

-  70, 100, 120:

  1200 x 800 x 670 mm (WxHxD)

This makes it possible to transport all 

models in one piece through a normal 

door. The boiler can be picked up 

sideways or from the front with a forklift 

truck for transport.

The R40 ECO can be transported 

with a crane. However, it must be 

ensured that the boiler is attached in 

its packaging to a pallet. Loading belts 

should be attached to the pallet. 

Unpacking instructions are printed on 

the cardboard box. Please follow the 

proposed steps.

Disassembly of panelling

The panelling has been packed 

separately from the boiler in the 

packaging. The panelling of the 

boiler should be set aside, before the 

assembly and until the boiler is taken 

into operation, so as to avoid damage.

Panelling should be attached and

secured with the supplied screw, 

after assembly of the boiler, or after 

maintenance works.

Lifting and carrying precautions:

-  Lift only a manageable weight, or 

ask for help.

-  When lifting the boiler, bend the 

knees, and keep the back straight 

and feet apart.

-  Do not lift and twist at the same 

time.

-  Lift and carry the boiler close to the 

body.

-  Wear protective clothing and gloves 

to protect from any sharp edges.
