ASSEMBLING THE 5500 RETRO-FIT
 
 
1. Unscrew the (3) 8-32 x 3/8 BHSCS from the Top Cap (3078HC) to separate the Top Cap from
the (3) support rods (3080HC) using the 3/32” socket screw key provided. See Picture 2.
2. Remove the (2) Hose Barbed Connectors from the Cooling Sleeve. This will help with
installation of the Retro-Fit Assembly into the head.
3. Loosen the (2) 8-32 x 1/4 SHSS in the Bottom Cap (3079HC) to allow Bottom Cap and rods to
move freely around magnetic drive assembly body.
4. Screw the Retro-Fit Assembly (A3086HC_) into the head of the existing reactor making sure
the ears of the bottom cap are clear of any external fittings. Again some external fitting may
have to be removed for easier installation. See picture 3.
