4.2 Transport 

 
The heat pump is to be transported and stored 
in a packaged condition. Careful transport at an 
angle of 45° is allowed over short distances. 
Ambient temperatures of –20°C to +45°C are 
allowed both for transport and storage. The 
standard packaging affords no protection 
against weather and sea-water.  
Transport damage can only be recognised if 
this is made known to the driver of the delivery 
vehicle during unloading. 
 
 

4.3 Installation 

location 

 
The GMLW heat pump can be installed in any  
dry and frost free room. 
The installation must take place on a level sur-
face. The location of the appliance is to be se-
lected such that operation and maintenance  
are possible at any time. 
 
(Clearance from the rear of the heat pump to 
the wall - min. 50 cm, clearance from the side 
of the heat pump to the wall - 30 cm, clearance 
from the front of the heat pump to the wall - 70 
cm).  
The heat pump must be decoupled acoustically 
from the floor.  
Reverberant

 

rooms can lead to increased noise 

sensitivity. A possible noise transfer to adjoin-
ing rooms cannot be ruled out and must be 
considered during the design. 
 

4.3.1 

Installation of split outdoor unit 

 
The installation of the split outdoor unit (evapo-
rator) is only permissible in the open air and is 
to be carried out in such a way that the air-flow 
is not hindered on any side.  
 
 
 
 
 
 
 

 
A maximum of one side may face a wall. A 
minimum clearance of 1m must be ensured.  
 
 
 
 
 
 
 
 

Fig. 2: Minimum clearance to a wall 

 
A minimum of 3m clearance above the unit is to 
be ensured. Installing the unit in a hollow is not 
permitted.  
 
 
 
 
 
 
 
 
 
 
 
 

Fig. 3: Minimum clearance to a ceiling 

The distance from the heat pump to the evapo-
rator is usually up to 10m (horizontal). The 
maximum permissible difference in height (top 
edge of evaporator) is 7m. Larger distances are 
to be agreed with the factory in advance.  
 

The following points are to be heeded when 
installing the evaporator: 

 

 avoid installing on hard floors which could 

transmit vibration  

  installing between two walls could lead to an 

increase in noise level 

 

Pointer for the installation: 

The higher the performance rating of 
the heat pump, the louder the noise 
made by the compressor.
