Important Safeguards:
The following safety precautions should always be followed when using CRYOTherm.
1. Use CRYOTherm only as directed in this manual. Improper use can cause injury.
2. Do not plug CRYOTherm into any electrical outlet that is not protected by a ground fault interrupter and matches
the voltage and amperage specification.
3. Do not modify the power cord in any way or use with any type extension cord.
4. Maintain CRYOTherm as described in this manual. Improper maintenance can cause injury.
5. Use only Grimm-approved parts or service. Improper parts or service can cause injury.
6. Do not utilize warm or hot water treatment where there is hemorrhaging or swelling.
7. Advise patients to refrain from adjusting controls, and never leave patients alone.
8. Thoroughly clean the tanks with a disinfectant between treatments, particularly after treating open lesions (see
“Maintenance” section of this manual).
9. An antibacterial agent added when filling the tanks helps prevent or reduce infection.
10. Keep loose material (bandages, gauze, washcloths, etc.) out of tanks as they can block pump intakes.

Installation:
1. Site Preparation
The attached Spec Sheet indicates the utilities necessary for installation of the CRYOTherm. Consideration should
also be made for the 6,186-pound load this unit will place on the floor and building structure.
2. Level CRYOTherm
Fifteen 5/8-11 stainless steel hex head leveling feet are provided to give uniform support. Thread these into the frame
before positioning the unit. Place a level on the top Corian surface and level the CRYOTherm.
3. Drain Connections
A 1-1/2-inch copper drain connection is provided. This should be positioned over an open, trapped floor drain with an
adequate air gap. Refer to local plumbing codes for specific requirements.
4. Cold Water Supply Connection
A ¾” NPT connection is provided for connection to the cold water supply. An internal backflow preventer protects the
supply and requires annual inspection. This supply fills the tank and cools the condensing unit.
When the supply pressure fails, the high-pressure cutout on the refrigeration system will trip making it necessary to
press the reset button (see #13 under control functions) after the pressure is restored.
5. Electrical Connection
Power requirements for the Model 4500 CRYOTherm are 208-240/120 volt, single-phase, 60 hertz, 28 amps.
Only plug the CRYOTherm into a voltage-matched NEMA 14-50A 3-pole, 4-wire grounding outlet that is properly
grounded, polarized, and ground-fault-circuit-interrupter (GFCI) protected.
Use professional electrical assistance and follow the National Electrical and local codes as a minimum.

Operation:
1. Operator Considerations
Operators should have a working knowledge of clinical hydrotherapy and cryotherapy procedures. They should also
have a complete understanding of the procedures described in this manual, the ability to operate the CRYOTherm,
and assist patients.
2. Fill Tanks
If prescribed, add an antibacterial agent to the water at this time. Follow the antibacterial agent manufacturer’s
directions for use.
With Fill, Pump, and Cool switches “Off” on both tanks and drain valves “Closed” press Power Switch to “On”. Now
press Fill switches to “On” and allow water level to rise. An automatic level switch located behind the overflow grille
will control the water level just below the overflow pipe height. These level controls have a ten-second delay with the
under-level condition to avoid valve chatter.
3. Switch Pump “On” and Adjust Hydrotherapy Jets
When tanks are full, turn Air Control Valve to “Min” and press Pump switch to “On”. Pumps will begin circulating the
water. Pump must be left on at all times for proper operation of the temperature control. Without circulation ice will
form on the tank walls.
Tank has six adjustable hydrotherapy jets. When the 1-horsepower, dual-speed pump is switched “On” it circulates
water through these jets in the low-speed mode. Press the black “Hi” button over the Pump switch for high-speed
hydrotherapy. After 20-minutes the pumps will resume low-speed operation automatically. Turn Air Control valve to
“Max” for more vigorous aerated hydrotherapy.
4. Select Temperature
The temperature is adjustable from 40°F to 60°F. To set the temperature press the black Press-To-Set button and
the digital display will switch from reading the water temperature to indicating the set point temperature. Using the
small screwdriver supplied, adjust the set point to the desired temperature. When the button is released, the digital
display will immediately return to reading the actual water temperature. Press the Cool switch to “On” and the
CRYOTherm will seek the set point temperature and control at that point.
5. Patient Loading
CRYOTherm is ergonomically designed to accommodate all size patients and support them either standing in the
tanks or sitting anywhere on the Corian surfaces.

Maintenance:
1. Clean Regularly
After patient use, clean the tanks thoroughly with a disinfectant and inspect for contaminates, particularly after treating
open lesions.
Note…The entire CRYOTherm should be inspected, cleaned, and disinfected at least once a week.
Caution…When cleaning CRYOTherm wear protective gloves.
2. Disinfection Procedure:
a) Turn Power switch “Off” and drain tanks before disinfection.
b) Apply solution of diluted bleach (1/4 cup bleach to one gallon water) or EPA approved intermediate level
disinfectant with cloth or sponge. Wet surface thoroughly and allow to remain wet for ten minutes.
c) Rinse with clean water to reduce residue of disinfectant on the surfaces to a non-toxic level.
d) Examine tank walls, exterior surfaces, and associated components for damage and visual cleanliness.
3. Culturing
Routine culturing of the tanks should be done. Guidelines for culturing can be obtained through clinical laboratory or
hospital infection control department.
4. Replace Filter:
Filter should be changed following a positive culture or when circulation is impaired.
a) Turn Power switch “Off” and drain tanks before replacing filters.
b) Open top air relief valve and remove drain valve to allow water to drain from filter housing.
c) Remove filter housing top and any collected debris from bottom of the filter housing.
d) Reinstall new filter cartridge in filter housing. Be sure o-ring is in place on threads.
e) Clean o-ring. For ease of future disassembly, apply a very light film of silicone lubricant to o-ring and threads.
f) Screw filter housing with o-ring into filter head. Do not over tighten. Tighten drain valve and top air relief
valve.
