Always disconnect and isolate the main electrical supply before installing, maintaining or repairing this equipment. All 
maintenance/repairs should only be carried out by a competent electrician or Schwank/Infrasave appointed technician.  
To ensure the air curtain operates efficiently, the air inlet and outlet grilles, fan impellers, housings and motors must be kept free 
of dust and debris. Weekly vacuum and clean any build-up of dirt and debris within the air curtain (please note that the motor is 
permanently lubricated and require no additional lubrication). Once the air curtain has been cleaned check all electrical 
connections to the unit ensuring they are tight and have not become loose. If the outer casing requires cleaning this should be 
carefully done using a damp soft cloth. Do not use solvents or abrasive materials.  Reinstate the electrical supply and fully 

function test the air curtain to ensure correct operation.

determines to be defective in workmanship or material for a period of one (1) year from the date of installation, unless otherwise 
specified below. This warranty applies to the heater’s original owner, and subsequent transferees and only if the unit is installed,

WHAT IS NOT COVERED

normal wear due to use, alteration or operation contrary to the owner’s manual or if the serial number has been altered, defaced or 

removed.  This warranty shall not apply if the electrical input to the product varies by more than ±10% of the rated input on the 
rating plate.  The Manufacturer shall not be liable for any default or delay in performance by its warranty caused by any 
contingency beyond its control, including war, government restrictions, or restraints, strikes, fire, flood, acts of God, or short or 
reduced supply of raw materials or products.
