PRODUCT WARRANTY STATEMENT

 

The  manufacturer  warrants  the  product(s)  supplied  to  be  free  from  defects  in  materials  and  workmanship  when  selected,  applied, 

installed, operated, serviced and maintained under normal use and in accordance with all established industry standards and generally 

accepted  field  practices  for  a  period  of  (12)  months  from  the  date  of  installation  or  (18)  months  from  original  manufacture  date  - 

whichever ocurrs first.   
 

The manufacturer shall, at their sole discretion, repair or replace any product which, based upon their own or their agents inspection, has 

failed due to a defect in design, workmanship or materials.  This warranty does not cover any product which has failed due to ordinary 

wear  and  tear,  damage  during  original  shipment  or  installation,  improper  application  or  design,  operation,  service  or  maintenance,  or 

which  has  been  subjected  to  products  of  corrosion  -  either  internal  to  the  sealed  refrigeration  system  or  external  in  the  immediate 

environment of the equipment installation.   
 

In the case of any products which must be returned to the sellers manufacturing facility for inspection and / or repair, return freight will be 

pre-paid  via  regular  ground  service,  the  product  inspected  and  either  replaced  or  repaired  and  re-shipped  via  ground  service.    Such 

actions shall be construed as satisfactory to satsify any and all warranty obligations by the original manufacturer. 
 

Prior to the return of any product, written approval must be obtained from the manufacturer along with an RMA number (Return 

Material Authorization).  Any product returned without prior approval and no RMA number will be refused! 

  

The manufacturer shall have no liability whatsover for any or all of the following which might be incurred as a result of product failure.  

These include (but may not be limited to); 
 

          -  Field Labor And Materials  

          -  Product Loss 

          -  Property Damage 

          -  Injury To Personnel 

          -  Temporary Equipment Rental / Storage Charges 
                    

   -   Installation Charges—including but not limited to labor, materials (including refrigerant), rigging and handling equipment,   

             disposal charges, environmental fees, etc.. 
 

For  any  component  /  parts  or  coatings  supplied  with  the  unit  but  not  directly  produced  by  the  unit  manufacturer  only  the  warranty 

provided  to  the  manufacturer  will  be  extended  to  the  customer.    No  other  warranty  shall  be  assumed  or  implied  by  any  third  party 

supplier.    Any  repairs  or  modifications  made  to  equipment  or  integral  components  by  a  third  party  or  end  user  without  previous 

authorization from the original equipment manufacturer will be the sole responsibility of that party. 
 

Product warranty coverage shall remain intact for the (1) year warranty period based upon the original unit ship date regardless of any 

changes  in  ownership  of  the  equipment  or  the  servicing  agent.    Removal  or  otherwise  defacing  of  the  original  unit  rating  label  will 

constitute forfeiture of all product warranty coverage for any reason. 
 

Warranty coverage is applicable only to static equipment installations  — the manufacturers products are not intended for installation in 

transport  or  mobile  applications  of  any  kind.    In  order  to  make  any  claim  of  warranty  coverage  you  must  first  contact  the  equipment 

manufacturer or their authorized agent and present them with the original unit serial number, date of installation and a full description of 

the specific failure which has prompted the warranty claim request.      Warranty contact information for LU-VE products distributed and 

sold within the continental US is as follows;

RECEIVING AND INSPECTION

 

When the equipment is initially received, a responsible individual acting on behalf of the equipment purchaser must be present to check 

the quantity of cartons and crates being delivered against the bill of lading to confirm that all items listed therein are accounted for. In-

spect  all  shipping containers (boxes  and  crates)  for  any  signs  of  visible  damage.    Report  any  damage  or shortages  to  the  delivering 

freight company immediately.  It is the customer's responsibility to file all claims with the freight company.   Damaged equipment may be 

refused but must not be returned to the manufacturer for any reason without prior authorization.    

 

 

Installing personel must excercise caution when removing equipment from crates and boxes to prevent physical injury to themselves or 

the  product.    Always  wear  appropriate personal  protection equipment  (PPE)  such  as  hard  hats,  gloves, safety  glasses,  safety  shoes, 

long sleeve shirts and pants, etc. to avoid physical injury.  When lifting smaller units by hand always utilize proper lifting techniques to 

avoid personal injury.  Equipment should be left in the original shipping container whenever possible until just prior to installation.  Do not 

use  piping  connections,  fan  guards,  drain  pans  or  other  such  similar  components  as  lifting  points.    On  larger  units  which  must  be 

removed from the shipping container or skid with lifting straps make sure to utilize a spreader bar to avoid damage to the units sheet 

metal housing.  

REMOVING EQUIPMENT FROM SHIPPING CONTAINERS / PACKAGING

 

If using a forklift roll the unit over onto a wooden pallet with the shipping skid “up” (

Figure 1 - Steps 1 & 2 - Page 6

).   

Remove  the  banding  which holds  the cardboard  box  to  the  shipping  skid,  then  using  a  razor  knife, carefully cut  the  box  down  all  (4) 

corners and fold the cardboard down onto the pallet, leaving the unit resting on the original cardboard shipping blocks and carton top 

flaps (

Figure 2  - Step 3 - Page 6)

.  

 

Remove both the left and right side cover panels to gain access to the nuts and bolts holding the front mounting feet to the shipping skid.  

Remove all (4) bolts and lay aside the shipping skid (

Figure 2 - Steps 4, 5 & 6 - Page 6

).   

 

With the carboard shipping container cut away and the side access panels removed from the unit check closely for any concealed or 

hidden damage.  If any damage is noted, report it to the manufacturer immediately before proceding with the equipment installation.  All 

units are shipped with approx. 25 PSIG of dry air or nitrogen holding charge in the coil. Use an accurate suction service gauge to verify 

internal coil pressure prior to proceeding with the unit installation.  Although the absence of pressure or a lower than normal pressure 

reading does not necessarily indicate a leak, if the reading is “low” a leak test must be performed before contrinuing with the installation 

or returning the unit to the distributor or manufacturer
