PLEASE ADHERE TO INSTRUCTIONS PUBLISHED IN THIS MANUAL.

Failure to do so may be dangerous and may void certain provisions of your warranty. 

For further assistance, please call:

 

     

WARRANTY:  Under normal use the Company 

 

warrants to the purchaser that defects in material or  

workmanship will be repaired or replaced 

 

without charge for a period of 18 months from 

 

date of shipment, or 12 months from the start date of  

operation,  whichever  expires  first.    Any  claim  for  

warranty must be reported to the sales office where the  

product was purchased for authorized repair or 

 

replacement within the terms of this warranty.   

Subject to State or Provincial law to the contrary, the  

Company will not be responsible for any expense for  

installation, removal from service, transportation, or  

damages of any type whatsoever, including damages  

arising from lack of use, business interruptions, or  

incidental or consequential damages.  

The Company cannot anticipate or control the 

 

conditions of product usage and therefore 

 

accepts no responsibility for the safe application and  

suitability of its products when used alone or in 

 

combination  with  other  products.  Tests  for  the  safe  

application and suitability of the products are the sole 

responsibility of the user.  

This warranty will be void if, in the judgment of the  

Company, the damage, failure or defect is the result of:

•  vibration, radiation, erosion, corrosion, process 

 

contamination, abnormal process conditions, 

 

temperature and pressures, unusual surges or  

pulsation, fouling, ordinary wear and tear, lack of  

maintenance, incorrectly applied utilities such as  

voltage, air, gas, water, and others or any 

 

combination of the aforementioned causes not  

specifically allowed for in the design conditions or  

•  any act or omission by the Purchaser, its agents,  

servants or independent contractors which for 

greater certainty, but not so as to limit the generality  

of the foregoing, includes physical, chemical or  

mechanical abuse, accident, improper 

 

installation of the product, improper storage and 

handling of the product, improper application or the  

misalignment of parts.  

No  warranty  applies  to  paint  finishes  except  for  

manufacturing defects apparent within 30 days from 

the date of installation.  

The Company neither assumes nor 

 

authorizes any person to assume for it any other  

obligation or liability in connection with the product(s).  

The Purchaser agrees that all warranty work required  

after the initial commissioning of the product will be  

provided only if the Company has been paid by the  

Purchaser in full accordance with the terms and 

 

conditions of the contract.  

The Purchaser agrees that the Company makes 

no warranty or guarantee, express, implied or 

statutory, 

(INCLUDING ANY WARRANTY OF 

 

MERCHANTABILITY OR WARRANTY OF FITNESS 

FOR A PARTICULAR PURPOSE) written or oral, of 

the Article or incidental labour, except as is expressed 

or contained in the agreement herein.  

LIABILITY: Technical data contained in the catalog or 

on the website is subject to change without notice. The  

Company reserves the right to make dimensional and 

other  design  changes  as  required.  The  Purchaser  

acknowledges the Company shall not be obligated 

to modify those articles manufactured before the 

 

formulation of the changes in design or improvements 

of the products by the Company.  

The Company shall not be liable to compensate or  

indemnify the Purchaser, end user or any other party 

against any actions, claims, liabilities, injury, loss, loss 

of use, loss of business, damages, indirect or conse-

quential damages, demands, penalties, fines, expens-

es (including legal expenses), costs, obligations and 

causes of action of any kind arising wholly or partly 

from negligence  or  omission  of  the  user  or  the  mis-

use, incorrect  application, unsafe application, incor-

rect storage and handling, incorrect installation, lack 

of maintenance, improper maintenance or improper 

operation of products furnished by the Company.
