Condition and guarantee

This unit is new and unused. We bought it as surplus, not through the manufacturer's dealer channel, so the factory warranty does not apply. We check the nameplate against the listing and photograph the actual unit. If it does not match the description, send it back within 30 days for a full refund. Not sure it fits? Ask us and we will confirm before you order.
