MediPac, Tank-Feed Operator Manual
SYSTEM COMPONENTS: STORAGE TANK and LEVEL
CONTROL SYSTEM
DESCRIPTION:
The storage tank is typically made of polyethylene, and has a
conical bottom to facilitate complete draining. It is equipped
with spray heads (nozzles) to continuously wash down and
broadly distribute disinfectant over the inside surface. There
is a sealable top hatch, and pressure regulating valve to
regulate loop pressure. A submicron air filter is included to
reduce microbiological contamination.
A vital part of the level control system are the proximity water
level sensors used to control the RO, turning it on and off, and
to activate an alarm in a low water level condition. These three
sensors are stacked vertically and spaced according to the size
of the storage tank.
- The bottom sensor will activate an alarm when the storage
tank’s water level falls below this sensor, signaling a low water
level condition.
- The middle sensor will start the RO for water production when
the storage tank’s water level falls below this sensor.
- The top sensor
will turn the RO off when the storage tank’s water
level reaches this sensor, signaling sufficient water is available.
The
Level Control System
is operated by RO’s Tank/Direct
Mode Switch, and is activated when in Tank Mode. If this switch
is in Direct Mode, the level control system is deactivated causing
the RO to run until manually shutoff. On a Tank Feed system the
only time the RO should be placed in Direct Mode is during the
disinfect procedure when it is required to raise the water level in the
tank to is capacity for complete disinfection and rinsing. The MediPac
Control Box has a Tank Alarm On/Off Switch which will mute an audible
alarm. The alarm should be muted during disinfection since the storage
tank water level will be raised and lowered several times.
MAINTENANCE:
- Replace tank vent air filter every 3 months.
