Component Identification (Figure 4)
(18) Heater Cup Assembly. The heater cup assembly consists of the heater cup to support
the boiler, and the heating element itself.
(19)
Boiler. The 1 liter boiler contains the boiling water that is the source of steam for the
distillation.
(20) Water Fill Valve. The valve dispenses water into the boiler when it is energized. The
inlet of the valve is equipped with a filter screen, to prevent fouling with particulate
matter.
(21) Plastic Check Valves. These valves function as vacuum breaks, preventing negative
pressurization of the system after it is shut off.
(22) Steam Control Valve. The steam control valve directs steam from the boiler to the
drain pipe during standby, or the steam delivery tube during distillation. The valve is
controlled by the timer switch.
(23) Drain Pipe. The drain pipe acts as a condenser for the steam not used in the distillation
and as a drain for the condenser cooling water. DO NOT restrict the discharge from the
drain pipe or its hose. The RapidStill II may be damaged by high water pressure.
(24) Flow Restrictor. The flow restrictor prevents the cooling water flow rate from
exceeding 1.0 gallon per minute. This minimizes water usage and prevents damage to
the unit.
(25) NaOH Pump. The peristaltic pump dispenses a user-supplied caustic solution from its
container directly into the digestion tube. The pump inlet and outlet are equipped with
quick connects to reduce the possibility of spillage during maintenance. The pump
must be rinsed with purified water at the end of every work day to prevent damage to
the pump or its fittings.
(26) Water Inlet Fitting. The water inlet fitting is a push-on style fitting designed to
connect tot the feed water line supplied in the installation kit.
(27) Electrical Connector. The electrical connector mates with the power cord supplied in
the installation kit.
(28) Fuse. The 15 amp fuse protects the RapidStill II from an electrical overload. Replace
this fuse with the appropriate replacement part. NEVER attempt to install a fuse with a
higher amperage rating.
