Balmar Warranty

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 

(2) years 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.

Warranty Return Material Process

1.
