PLUMBING CONNECTIONS
General plumbing instructions:
 Use a minimum of 5/8-inch (inside diameter) high temperature flexible hose or 1/2 inch
piping to and from the Little Cooler for coolant circulation.
 Use sweep elbows or large radius bends to reduce frictional losses in the piping. Length of
coolant lines must not exceed 50 feet.
 The WATER OUTLET of the Little Cooler plumbs to the condenser or WATER INLET of the
distillation unit. The WATER OUTLET from the distillation unit’s condenser returns to the
WATER INLET of the Little Cooler.
 If using a JetVac attachment with your solvent distillation system:
1) Install a tee into the coolant lines. Plumb the JetVac to the branch side of each tee (for
both the water and the water out).
2) Install a ball valve on the water out side, after the tee to the JetVac unit (this is used to
restrict the flow to the JetVac unit if the flow switch for the distillation unit is not being
satisfied).
 Plumb a Y-strainer in line to the WATER INLET side of the distillation unit. This is to catch
any foreign matter or debris that enters into the cooling system (Note: models LS-15IIE and
LS-55IIE already have a Y-strainer factory-installed inside their cabinet).
NOTE: When installing the Little Cooler to models LS-15IIE or LS-55IIE, the water solenoid
valve inside the Still may need to be bypassed. The solenoid significantly reduces coolant flow
capabilities, thereby hindering the performance of the Little Cooler. Whether or not this is
required depends on the amount, type, and distance of plumbing between the Still and the
Little Cooler.
NOTE: Do not use the Little Cooler for the optional “Quick-cool” feature of an LS distillation
system. Use tap water only for this feature.
NOTE: If using the Little Cooler with an LS-15IIE or LS-55IIE refer to the “Special Plumbing
Requirements...” section of this manual for additional instructions.
