Required tools: 7/16” box or socket wrench

11/32” nut driver or socket wrench

(2) Needle-nose vice grips

1. Place a packing blanket or cardboard on the floor to prevent scratching the

exterior of the enclosure.

2. Tilt the enclosure over on its flat side. The intake and exhaust ports should not

be on the floor.

3. Reaching in through the projection port, attach and lock a needle nose vice grips

to the (2) spring ends. Remove the 7/16” nut and washer. Carefully lift the

spring hook off the bolt and let it slowly retract. Leave the vice grips on the

spring end to prevent it from retracting into the spring housing. Do this for both

left and right springs.
