1. Parts List

Most of the water will drain out. Tilt the bath to drain more of the water. Wipe the inside of the

BATH and the RACK with a bleach towelette or a 10% bleach solution. Mount a new BLADDER to

replace the leaked BLADDER in the RACK. Reassemble (See SETTING-UP). Plug in and turn on

the unit and push START and let it run for a few minutes so that the water passes through and

rinses the pumps and the BLADDERS on the inside. Turn the unit off, drain out all the water a

second time. Reassemble (see SETTING-UP). The unit is ready to start thawing.

BLADDER REPLACEMENT

Hold the BLADDER so that the holes in the FITTINGS (water connectors) face down. Push the top of the

BLADDER underneath the black rod that passes across the RACK near the back of the RACK. Gently pull the

BLADDER up until the FITTING is lined up with the Stainless Steel PORT (Exit Tube) near the black rod.

Push down on the FITTING as you twist back and forth until the FITTING bottoms against the bottom of the

RACK.

Mount the other three FITTINGS the same way.

BLADDER STORAGE

When storing, roll the bladders up loosely, start with a 2.5 cm. (1") diameter. Do not fold. Folding the bladder

will crimp the internal venturi tubing. If the bladder is dry it can be stored in a zip lock bag. If the bladder is

wet then allow air flow around the rolled bladder.

MODES

STANDBY MODE. Just turn the unit ON. The unit heats up and maintains 37.0

THAWING MODE. Push START when in STANDBY mode to start thawing. The unit then recirculates

tempered water through the BLADDERS, and massages the plasma bags. The countdown timer indicates the

remaining time. The plasma bags are monitored for leaks. Timing out or pushing STOP ends thawing.

DIAGNOSTIC MODE. Is for technician access. Hold MINUS as you turn the unit ON.

1. To restore the unit to initial factory settings, press ENTER while still holding MINUS. The unit displays

"UNIT RESET". Turn the unit off. You have to re-calibrate the temperature after resetting the unit.

2. "PUMP TEST" is a diagnostic tool to check if each pump turns on. It is checked only when a pump does

not operate. Release MINUS then push ENTER to verify that you are a technician. The display shows

"PUMP TEST". MINUS turns on Pump 1, ENTER turns on Pump 2. Push PLUS to go to next function.

3. Overtemperature Alarm Test. Hold MINUS as you turn the unit ON. DIAGNOSTICS will be displayed.

Push ENTER. Push and release PLUS until ALARM TEST is displayed. Push ENTER, the heater will

heat continuously and the pumps will turn on. When the temperature reaches 1.0C above the target

temperature the alarm will sound. Turn Off the unit. If alarm does not sound, contact CytoTherm.

Alarm test should be performed every 3 months as part of unit maintenance.

Program the thawing time.
