Operator Manual OPTIONAL ACCESSORIES: Short & Extended Carts Better Water offers two models of carts to hold the PB2 and various accessories. Both are strong and lightweight, and includes casters, two of which lock. The extended cart is also designed to transport the dialysis machine as well.
OPTIONAL ACCESSORIES: Divert-to-Drain The Divert-to-Drain will automatically divert the product water from the PB2 to drain when the water quality monitor detects a poor water condition. It includes a “Good Water Quality” Light, and connection ports for “Product Out”, “From RO”, and “To-Drain”.
20” Carbon Block filter. The internal carbon block filter can either be used or replaced with a short bowl. These Carbon Tanks come in either 8”x30” or 9”x42” sizes. NOTE: 9”x42” tanks will not fit on the PB2 carts. part# part# EQASSYCFRO.8CF830PB2...
CAUTION The short bowl SHOULD NOT BE USED if there are no additional external Carbon Tanks and/or Carbon Blocks used in the pre-treatment of the feed water to the PB2. NOTE about O-ring: The short bowl uses the same O-ring as the 10” Big Blue Filter Housing. If replacing the standard filter housing with a short bowl the existing O-ring can be used but it is recommended that a new O-ring be installed.
PB2 – Mediport Portable RO Operator Manual OPTIONAL ACCESSORIES: False Tube the for Capsule Filter If the Capsule Filter is to be replaced with an alternative external filter of greater or equal capacity a false tube can be used in place of the filter. This false tube has the same type of connections as the filter and simply installed in place of the filter.
Electrical Requirements: - It is recommended that the PB2 be plugged into a dedicated G.F.I. plug, and be protected against electrical surges and be on a stable power supply. Do not use power strips or extension cords. Failure to follow these recommendations can cause the Water Quality Monitor and the Divert-to-Drain to operate improperly.

PB2 – Mediport Portable RO Operator Manual OPERATION Before you start using this device, operators must read and understand this manual in its entirety. This manual of Operator's Instructions describes in considerable detail all of the steps and procedures required to safely operate this device. With proper operation, maintenance, and care, this device should give you years of reliable service.
FAMILIARIZATION with WATER QUALITY MONITOR and PB2 CONTROLS The Water Quality Monitor is located on the front panel of the PB2’s control box, and contains the control switches and buttons for operating the PB2. The Water Quality Monitor monitors and displays vital information concerning the quality of water.
- If external carbon blocks or tanks are used, the internal carbon block should have been removed and replaced with a false cartridge. - Open the PB2’s cabinet door and obtain a sample of water from the Labcock located on the inlet solenoid valve.
… If the PB2 has not been used at all during any given day, simply connect and flush for 15 minutes. This is not required but will increase the life of the membrane.
If a low pressure condition persists, it will alarm again and additional measures should be taken to correct the issue. Water pressure must be above 20 psi before the PB2 will reset. Below are a few solutions for this condition which should be tried before contacting Technical Support.
PROCEDURE 1. Disconnect the blue product hose from the PB2’s Product Port. 2. Cut a small piece off of the blue product hose long enough to go between the PB2 and the John Guest “Y” Fitting. 3. Connect one end the short-cut piece of blue product hose to the PB2’s Product Port and the other end to the single leg of the John Guest “Y”...
- Quarterly: Low pH Clean with BWI-1000, High pH Clean with BWI-2000, and Disinfection with Minncare (in that order). - If the PB2 has been in storage and should have been loaded with preservative, then after performing the initial setup the following should be done: Low pH Clean with BWI- 1000, High pH Clean with BWI-2000, and Disinfection with Minncare (in that order).
