BALMAR WARRANTY

Balmar Limited Warranty

Balmar’s Limited Warranty covers defects in material or workmanship on new Balmar products generally for a period of one (1) year from 

the purchase date. Only consumers or dealers purchasing Balmar products from authorized Balmar retailers or resellers and installed 

by a qualified installer may obtain coverage under Balmar’s Limited Warranty. Components with a manufacturing date greater than ten 

(10) years old are not covered under the Balmar Warranty, even if the purchase date has been within the past two (2) years. Purchase 

from unauthorized resellers, which may include some online entities, may not guarantee the purchaser will receive a newly manufactured 

component, and therefore does not guarantee Warranty coverage.

Warranty Resolution

If Balmar authorizes a product to be returned to Balmar or an authorized service provider, Balmar will repair the product or replace it without 

charge with a functionally equivalent replacement product. Balmar may replace the product with a product that was previously in service 

or repaired, but re-tested to meet Balmar specifications. Balmar will pay to ship the replacement product to the purchaser. By sending the 

product for replacement, ownership of the original product will be transferred to Balmar. Labor charges at the consumer’s site are not covered 

under this Warranty. Balmar warrants that repaired or replaced products shall be covered under the Balmar Warranty for the remainder of the 

original product warranty, or 90 days, whichever is greater.

Not Covered Under Warranty

Balmar’s Warranty does not cover any problem that is caused by (a) an accident, abuse, neglect, exposure to shock, electrostatic 

discharge, heat or humidity beyond the product’s specifications, improper installation, inappropriate operation/misapplication, maintenance 

or modification, or (b) any misuse contrary to the instructions provided with the product, or (c) loss, or (d) malfunctions caused by other 

equipment, or (e) acts of God. Examples of conditions not warranted: cracked or broken cases, parts damaged by fire, water, freezing, 

lightning, collision, theft, explosion, rust, corrosion, or items damaged in route to Balmar for repair. Balmar’s Warranty is void if a product 

is returned with removed, damaged or tampered labels or any other alterations (including removal of any component or external cover) to 

the product. Balmar’s Warranty does not cover labor charges or any direct, consequential, or incidental damages. Costs related to recovery 

removal or installation are not recoverable under the Balmar Limited Warranty.

Applicable Laws

Balmar’s Warranty is governed by the laws of the State of Alabama, USA. The Balmar Warranty provides the purchaser specific legal rights, 

and you may also have other rights that vary from state to state. Balmar’s Warranty does not affect any additional rights consumers have 

under laws in their jurisdictions governing the sale of consumer goods, including, without limitation, national laws implementing EC Directive 

44/99/EC. Some states do not allow the exclusion of limitation of incidental or consequential damages, so the limitation or exclusions of 

Balmar’s Warranty may not apply in certain jurisdictions.
