The Distributor shall be a current model under standard production by the manufacturer.
Any units not conforming to these specifications will be rejected, and it will be the responsibility of the manufacturer to conform to the requirements unless deviations have been specifically cited by the bidder and acceptance made on the basis of the exception.
FUNCTION
The Distributor shall perform the following functions:
a. Fill tank by Distributor pump from outside source.
