IMPORTANT INFORMATION

Taking Delivery of Equipment:When taking delivery of your equipment, please be sure to check the shipment for any

potential damages (MorrHeat is not responsible for any damaged shipments if signed for non-damaged).Ifanydamageisidentifiedupondelivery,eithersignforasdamagedgoodsspecificallynotingindetailtheapparentdamage/or/refusetheshipmentcompletelyandbesuretofileaclaimwiththeshippingcompanyimmediately regardless of the damage.

consideredwhencleaning,maintainingandoperatingwasteoilheaters.

It is recommended to use a filter or some kind of strainer when pouring waste oils into the storage tank(s). This will increase chances of catching any particulates prior to the pump filter(s) to insure a cleaner fuel

source.
