Page 4 of 8 Assembly For units with the strainer assembly shown in fig. 1, it is necessary to replace the bulkhead at the base of the tub. If the unit does not have the assembly, skip to step 3. fig. 1 STEP 1 Begin by removing the old bulkhead and cleaning the area around the 1" diameter hole in the tub. STEP 2 Insert the 1-14 UNS thread end up through the bottom of the tub and secure with the 1-14 UNS brass nut with the stepped edge facing the bulkhead and the nylon washer. Note: Tighten the nut to the bulkhead using an impact gun if possible. The nut and bulkhead must be properly sealed to avoid future leaking of solvent. STEP 3 Slide the flare nut over the flared tube and finger tighten to the bulkhead at the bottom of the tub. Note: With the conversion of the pump, it is no longer necessary to use the ball cage assembly. 2 STEP 4 Begin mounting the pump by positioning the bracket on the outside of the legs on the left side of the unit and mark locations for drilling through the leg. The holes should be positioned about 5. 00" up from the bottom of the legs. The legs can be flexed slightly in for mounting if there is not ample material to drill through. STEP 5 Drill through the legs and clear any burrs. Put the pump bracket in place, inside the legs, and attach using (1) 1/4-20 x 1/2" bolt, (1) 1/4" lock washer, (1) #10 flat washer and (1) 1/4-20 acorn nut for each side. STEP 6 Position the pump so that the grounding bar is facing away from the unit and attach with (1) 1/4-20 x 1 bolt, (1) 1/4" flat washer, (1) 1/4" lock washer and (1) 1/4-20 nut for each side.
