8.2 SINTERED FILTER KIT
ACE KIT2: filter assembly (1 pc.)
8.2.1 SINTERED FILTER INSTALLATION
INSTRUCTIONS
1. Remove shroud and pre-filters and place all parts in a secure area.
2. Using a 1” socket wrench, remove all filters from the enclosure (top and
bottom).
3. Remove rubber caps from explosionproof filters.
4. Apply thread grease to threads of explosionproof filters.
5. Install new filters (top and bottom) and torque each to 133 ft.-lbs. (180 N-m).
6. Install pre-filters and shrouds; refer to Sections 2.6 and 2.7.
6. Be sure to stretch pre-filter elastic band completely around the explosionproof
filter and seat the elastic band on the filter’s threads. This will ensure all air
flow to the bottom filters passes through the pre-filters.

8.3 BLOWER KIT
ACE KIT3: blower, manifold and hardware (1 pc.)
8.3.1 BLOWER INSTALLATION INSTRUCTIONS
1. Disconnect blower power, ground and
control leads from terminal blocks.
2. Loosen four (4) nuts holding blower
bracket and baffle to mounting plate.
DO NOT remove.
3. Loosen and remove manifold clamp
bracket nuts and lock washers.
DO NOT remove jam nuts positioned
behind the manifold clamp bracket.

4. Remove blower and brackets.
5. Remove manifold and manifold clamp bracket.
6. Remove blower cooling intake and hose clamp from old blower assembly and
hold for re-assembly.
7. Loosen and remove three (3) screws holding the baffle to the blower bracket.
Remove baffle and hold for re-assembly.
8. Attach baffle to new blower bracket using the same three (3) screws.
9. Align new manifold to enclosure wall.
10. Align new manifold clamp bracket to threaded studs. Be sure the manifold
clamp bracket flanges point toward the interior of the enclosure.
11. Install four (4) lock washers and nuts on threaded studs hand tight before
applying required torque. Tighten to 20 in.-lbs. DO NOT over-tighten.
12. Slide new blower/bracket assembly into place until fully seated, aligning to the
threaded studs and the manifold.
13. Tighten nuts wrench tight.
14. Tighten manifold hose clamp, while compressing the manifold to the blower, to
20 in.-lbs.
15. Re-attach blower cooling intake and tighten hose clamp to 20 in-lbs. Be sure
to align bottom of blower cooling intake to the explosionproof filter at the
bottom of the enclosure.
CAUTION
To avoid system malfunction and electrical shock, be sure that all wires are
aligned in the baffle’s wire pass through.

16. Terminate the blower power wires to the appropriate terminal block (black to
black).
17. Perform a continuity check between each blower power terminal and each
phase of the integral disconnect switch.
18. Terminate the blower control wires to the appropriate terminal block (red to
red).
19. Perform a continuity check between each blower control terminal and the
XROI relay on the variable frequency drive.
20. Terminate the blower ground wire to the appropriate terminal block (with the
blower control wires) (yellow/green to green)
21. Perform a continuity check between the ground terminal and the ground lug
adjacent to the integral disconnect switch.
