Warranty Claims 

5. Prior to returning any product to BLACOH based on a claim of breach of Warranty or PTFE Bellows Warranty, a

BLACOH Return Request form must be completed. The form will be reviewed by BLACOH to determine if a Return 
Merchandise Authorization (RMA) number will be issued. The issuance of an RMA number does not constitute 
BLACOH's acknowledgment or agreement that the warranty claim is justified or correct. 

6. If an RMA number is issued by BLACOH, customer should then deliver the product in question to the address specified

on the RMA, freight prepaid. 

7. All products so returned to BLACOH based on a claim of breach of Warranty or of PTFE Bellows Warranty must be

cleaned, sanitized and neutralized prior to shipment to BLACOH. BLACOH will not accept any part that contains 
corrosive chemicals, organic cultures, blood, any harmful residue or air borne materials that might contaminate a 
breathable atmosphere or put at risk any person or property. Any shipment that does not comply will be returned at the 
expense of the customer, or the customer will be required to arrange for pickup. 

8. HAZMAT SHIPMENTS WILL BE REMOVED AND PROCESSED AT CUSTOMER'S EXPENSE.

9. Receipt by BLACOH of a return does not constitute BLACOH's agreement that BLACOH is in breach of its Warranty or

PTFE Bellows Warranty.

10. If BLACOH determines that a defect in workmanship or material of a part has occurred, customer is not entitled to a

complete unit replacement. In the event of such a defect, BLACOH will repair or replace the defective part or parts or
refund the purchase price, as BLACOH determines in BLACOH’s sole discretion.

New Product Returns 

1. If a customer wishes to return a new, unused product, the customer must first request a Return Merchandise

Authorization (RMA) number from BLACOH. BLACOH will determine if the unit can be returned for possible credit.  

2. Product to be returned must be new, unused, and of current design and purchased within thirty (30) days of the return

request. In addition the product must not have been damaged after original shipment by BLACOH. 

3. Product returns must be delivered, freight prepaid.

4. BLACOH has the right to inspect all returned products prior to acceptance or rejection.

5. ALL RETURNS are subject to a minimum $50.00 or 30% restocking fee, whichever is greater. (Higher restocking fees

may be charged on special items and some models may not be eligible for return). Returns accepted by BLACOH will be
credited to the customer's account less the re-stocking fee. Refunds will not be issued.

6. Any outsourced product supplied by BLACOH will be subject to the warranty, return policy and re-stock fee charged by

the manufacturer of the outsourced product.
