WARNING

 

The selection and installation 

of components external to the 

unit are the responsibility of the 

installer and must be carried out 

in accordance with good working 

practices and applicable standards 

of the country of destination.

WARNING

 

The hydraulic piping to the unit 

must be adequately sized for the 

required flow rate. The water flow 

rate through the heat exchanger 

must always be constant.

WARNING

 

Carefully clean the system prior to 

connection to the unit. This clean-

ing eliminates welding slag, dirt, 

rust or any other impurities from 

the piping. These impurities may 

otherwise be deposited within 

the unit and cause a malfunction 

The connecting piping must be 

adequately supported so as not to 

impose any weight onto the unit.

WARNING

 

SYSTEM DRAINING

During the winter period the water 

in the heat exchanger may freeze 

when the system is off, causing 

irreversible damage to the heat 

exchanger.

There are three solutions to avoid 

the risk of freezing

1.  Complete draining of water 

from 

the unit.

2.  Operating with glycol,  with 

a percentage 

of glycol se-

lected in accordance with the 

minimum anticipated external 

temperature. 

3.  Use of electric heaters.  

In

 

such cases the electric heat-

ers must always have power 

available for the whole period 

of possible freezing (unit in 

stand-by)
