IMPORTANT PRESERVICE INSTRUCTIONS 

 

 

 It is advisable for anyone to go through the following points before one actually works                     

   on the unit. 
 

 

Shipping bolts:

 The unit is shipped with 3 shipping bolts and spacers to avoid 

any damage to the unit during shipping. Make sure that all the shipping bolts and 
the spacers have been removed from the unit. 

 

 

Height of drain hose: 

The drain hose should be placed in such a way that the 

height of the drain hose does not exceed 36” and is not lower than 28” inches 
from the bottom of the unit. 

 

 

Water inlets:

 In this unit two water inlets are required to be connected for hot as 

well as for cold water. Make sure that water supply is provided to both the inlets. 
In case hot water supply is not available cold water supply should be connected 
to the hot water inlet valve. 

 

 

Leveling:

 The unit must be leveled properly for proper working of the unit. 

 

 

Flooring:

 The unit should be installed on strong and leveled floor, installation on 

carpet or wood increases vibrations. For better working of the unit, the unit should 
be installed on a thin carpet and in case of wooden flooring, proper bracings 
should be made and the unit should be installed on a sheet of plywood. 

 
 
 

Please note:

 All the above instructions are mentioned in the Owners Manual and if the 

unit is found to be malfunctioning due to any of the above points not been taken care of, 
the customer will be liable to pay for the complete service call along with the parts. If the 
customer is not willing to pay for the service we will be paying for the same but the 
customers warranty will be voided then.
