Operation:
Operators should have a working knowledge of clinical hydrotherapy and cryotherapy procedures. In addition, each
operator should thoroughly read and understand the procedures in this manual before treating patients with
CRYOTherm.
1. Fill Tank
The tank must be filled for proper operation of CRYOTherm. To fill the tank first make sure all control panel switches
are in the off position and the drain valve is closed. Press the power switch to on and then slide the fill switches to the
"Hi" or "Lo" level and allow the water level to rise. Automatic level switches located behind the overflow grille will
control water levels
at “Lo” = 4” and “Hi” = 2” to the top of the tank.
Note:
These level controls have a ten-second delay to avoid valve chatter.
Helpful Hint:
During contrast treatments level switches can be turned off to avoid loss of temperature due to tanks
being constantly filled with water to replace that discharged from the overflow.
2. Water Supply Requirements
CRYOTherm requires connection to a constant water source in order maintain water level and to allow the
refrigeration system to work properly. If water supply is lost the electronic unit controller will shut down the
refrigeration system and will require reset to restore function.
(see Control Function #13 and the troubleshooting section).
3. Switch Pump
“On”
When the water level covers all jets the pump switch
(see Control Function #4)
may be switched
“on” to begin circulating
the water.
WARNING: Do not run the pump when the tank is empty.
With the dual speed pump switched on water will circulate through the hydrotherapy jets at low speed. The pump
may be switched to high speed by depressing the white button on the console top
(see Control Function #10)
. After 20
minutes the pump will automatically resume low speed operation. The air control valve next to the pump speed button
can be turned to adjust the amount of aeration during treatment
(see Control Function #11)
.
Important:
The pump must be left on at all times for proper operation. Reliable aeration only occurs at high speed.
4. Select Tank Temperature
To set the temperature of the tank press and hold the
“Press-To-Set” button
(see Control Function #8)
, when depressed
the digital display will switch from reading the actual tank temperature to indicating the set point temperature. Insert
the small screwdriver that was supplied into the adjacent
slot labeled “Adjust
F”
(see Control Function #9)
and adjust
the set point to the desired temperature. When the button is released, the digital display will return to reading the
actual tank temperature.
5. Cool Switch
Slide the Cool Switch to “On” and the CRYOTherm will seek the set point temperature and control at that point.
Cooling rate is approximately four degrees per hour.
6. Patient Loading & Unloading
Users may access the tank via the compartment steps or over the front and side edges around the perimeter of the
tank. Users also have access to the pump speed button and air control dial during the course of treatment however
they should never touch the control panel settings beneath the clear plastic cover. CRYOTherm is designed to
accommodate all size athletes and support them standing, seated, or kneeling in the tank or sitting anywhere on the
exterior Corian surface.
