9

The surface is suitable for installation of the unit:

 

● The foundation is level and horizontal

 

● The  surface  and  the  foundation  have  a  load-

bearing capacity sufficient for the unit’s weight

 

9

Ground surface in the air outlet area of the heat 

pump is permeable to water

16.2 Transport to installation site

To prevent damage during transport, always transport 

the unit to final installation site in its original packaging, 

using a lifting truck, forklift or crane.

 WARNING

Several people are required to transport 

the unit. Do not underestimate the weight 

of the unit.

  “Technical  data / scope  of  delivery“,  from 

page 22, “General unit data” section.

Danger of tipping over during transport!  

This can result in personal injury and dam-

age to the unit.

 

► Take  suitable  precautionary  measures  to 

eliminate the danger of tipping.

 IMPORTANT

Never  use  components  and  hydraulic  con

-

nections on the unit for purposes of transport.

 IMPORTANT

Do  not  tilt  the  unit  more  than  a  maximum 

 

of 45° (in any direction).

Lifting the unit with pipes

only LW 140… and LW 180…

The units LW 140… and LW 180… can be lifted with 

¾” pipes (provided by customer) that are suitable for 

the  weight  of  the  respective  unit.  Special  holes  are 

provided in the frame for this purpose.

 NOTE

The unit type LW 251A cannot be lifted with 

pipes.

1.  Remove the lower facing panels of the unit.

  “16.4  Attaching  the  air  flow  baffles”,  page 11, 

point 1.

2.  Insert the pipes through the holes in the frame on 

the switch box side.
