LOW WATER First make sure that a pinch ( 0.01 gr) of salt was added if deionized water was used. Then
remove RACK to add water. Lift up the top layer of the bladders to let the water in the BLADDER drain down
into the BATH. Lift the front of the RACK and disconnect the RACK TUBING. Lift the RACK and put it
aside. Pour water into the BATH to the water label.
LEAK is an audible and written alarm that indicates that a plasma bag or BLADDER leaked.
MAINTENANCE
Daily: Wipe off the unit.
Every 3 months:
Replace the bladders and clean the bath.
1. Unplug the unit.
2. Remove and discard the BLADDERS by first lifting the top of the BLADDERS up to drain out as much of
its internal water as possible. Remove the INLET and OUTLET FITTINGS by holding the FITTINGS
and twisting them as you pull up.
3. Lift the front of the RACK and disconnect the RACK TUBING from the RACK, lift up the Rack and
place aside.
4. Drain the bath by attaching the provided tubing to the DRAIN valve. Most of the water will drain out.
Tilt the bath to drain more of the water.
5. Wipe the BATH and RACK with bleach towelettes or a 10% bleach solution. Use only water and bleach
towelettes or a 10% bleach solutions for cleaning. DO NOT USE CONCENTRATED BLEACH. Use
alcohol for removing oil or grease. Rinse off the bleach with water.
6. Close the DRAIN valve. Fill the bath with water to the water label. Place the RACK on the BATH. Do not
connect the RACK TUBING. Plug the unit in, turn it on and start a thawing cycle. Let the unit run for a
few minutes so that the water passes through and rinses the pumps.
7. Remove the RACK, and drain out the water. Close the DRAIN valve. Fill the bath with water. If you use
deionized or distilled water add a little pinch ( about 0.01 gr.) of table salt. Do not use saline solution.
Add 3 ml. of Algicide Part #ALG240 (1.0 ml. per 4 liter of water available in contiguous USA only) to the
water. Any other bath clearing agent can also be used.
8. Connect the RACK TUBING and position the RACK in place.
9. Mount new BLADDERS in the RACK .
Replace the air filter. Unscrew the filter cover, discard the old filter and mount the new filter. Screw on the
filter cover.
Stainless Steel Springs. The two stainless steel spring rods that push against the rack act as connectors to the
leak sensors in the RACK. Bend them out so that the bottom of the spring is 1.2 cm (.5") from the BATH wall.
In the very unlikely event that the spring breaks, please contact CytoTherm and we will rush you a new spring
with mounting instructions. The unit will work, but will not detect leaks, with a broken spring until you install
the new spring. Wipe the stainless steel springs and the stainless steel nuts on the front of the RACK with
alcohol to remove any oil or grease.
Leak Test Turn the unit ON. Take a slightly moist piece of a paper towel and touch it to both of the stainless
steel studs inside the front of the RACK. The alarm should sound and the display should say LEAK. If it does
not, contact CytoTherm.
Temperature Calibration. Run temperature calibration at least every 3 months or more often if your
institution procedures or regulations require. See PROGRAM MODE > TEMPERATURE CALIBRATION.
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
