Replacing Exhaust Filters
It is recommended to replace exhaust filters at the same time as replacing diaphragms.
Use tools 1, 2, 3, 6, 7 and 8.
(1)
Remove pump panels 1 and 2, piping, pump heads and valve retainers. The
procedure is the same as steps (1)-(3) in 3) Replacing DAL-181D Unit Valves.
(2)
Remove the urethane exhaust filters from the exhaust side of all the valve
retainers.
(3)
Use solvent to clean the fastening area of the exhaust filter. (Photo 27.)
(4)
Fit the new exhaust filter taking care to prevent it from collapsing in. Then check
to make sure the exhaust filter is not deformed.
(5)
Fit and fix in place the valve retainers, pump heads, piping and panels 1 and 2.
For 181D, this procedure is the same as steps (7)-(8) in 3) Replacing DAL-181D
Unit Valves. For 361S, this procedure is the same as steps (3)-(4) in 4) Replacing
DAL-361S Unit Valves.
