SERVICING
Shutting Down the Unit
1. Gradually decrease the pressure of both fl uids simultaneously
until all pressure is relieved.
2. Never open a superchanger unit when it is hot. Cool the
unit to a warm temperature before opening to prevent
personal injury and gasket loosening.
3. Completely drain fl uids from the unit.
Disassembly Procedures
To open the exchanger, it is necessary to disconnect all
connections (if any) to the “E” moveable frame. Lubricate all
bolts prior to disassembly. Then completely loosen and remove
all bolts except those indicated by a “fi lled circle” in the sketch
below for the size unit involved. The four remaining bolts can
then be loosened in any left-right sequence at 1/4 in. increments
until they can be lifted out.
3. To remove a plate from the frame:
(a) For UXP-005, UXP-010, UXP-100, SXP-070, SXP-400,
SXP-140, GC, GX and GFP-050, GFP-100 and GFP-150
Series, tilt the plate and remove it.
(b) GFP-030, GFP-080, UXP-200, UXP-060, UXP-400
and UXP-110 Series, lift the plate, push down on the hanger
to release it, tilt the plate and remove it.
(c) UXP-801 and UXP-802 Series, remove the sectional
guide bar track, which is bolted into the bottom of the upper
I beam near the moveable end. Tilt the plates and remove
them one at a time. (There are three of the removable
track sections along the guide bar length to facilitate plate
removal.)
