NOTE Only the portion of the drain line that is within the Bath Unit will be
heated. CANNON
® Instrument Company does not heat the length of
tubing which extends from the bath to the waste can.
Waste can
The waste can collects the waste solvent and sample residue drained from
the CAV. The customer must supply a waste can (typically a 5-gallon
safety gasoline can) and must empty the can as necessary. Disposal of
solvent/sample waste should be in accordance with appropriate safety
and environmental regulations. CANNON
® Instrument Company does
not supply a waste can with the CAV.
NOTE When positioning the waste can, make sure that the drain lines slope
down from the CAV to the waste can. This will help prevent any solvent/
sample waste from spilling back into the CAV. This will also ensure
proper and complete drainage of solvent and waste oil from the CAV.
Drip pan
The drip pan is located immediately below the expansion tank in the
CAV cabinet. It is designed to minimize the amount of liquid which
might spill onto
internal electrical
components. The drip
pan is sloped to drain
to the rear of the
cabinet. The drip pan
drain at the rear of the
unit must be con-
nected to the waste
can or another safe
container.
Ventilation
The CAV requires
installation of the
exhaust shroud on the
rear panel of the unit. The shroud must be connected to a customer-
supplied exhaust fan/ventilation system. The air flow rate and design of
the exhaust fan must be suitable to handle the vapors from the customer
supplied solvent and samples. If using multiple CAV Bath Units, exhaust
shrouds may be coupled together using shroud adapters (P/N P61.3424,
available from CANNON
® ). Otherwise, a 4" (10 cm) solvent-safe ventila-
tion hose should be connected to the exhaust shroud on each Bath Unit.
To attach shroud adaptors, remove the blank plate from the top or desired
side of the vent shroud. Then attach the adapter in its place.
