Warranty coverage
Robinair CoolTech vacuum pumps are warranted against defects in material and workmanship for one
year of normal use from the date of purchase. See your distributor for warranty details.
Out of warranty
A pump that is no longer covered by the one-year warranty period, and which fails to operate correctly,
should be returned to the distributor with a full, written explanation of the problem. Before returning an
out-of-warranty pump, review all maintenance procedures to avoid an unnecessary return. Replacement
parts are available for doing your own repair service.
Because of ongoing product improvements,
we reserve the right to change design,
specications, or materials without notice.
