R32
R32 refrigerant has a 68% lower GWP (Global Warming Potential) than
R410. While neither refrigerant deteriorates the Ozone layer like R22 did, there is a clear
winner when looking at potential to contribute to global warming via greenhouse gases.
R32 is a much more environmentally friendly alternative to R410 and we expect to see it
become the new environmentally friendly standard in the years to come.
THE LOW GWP
ALTERNATIVE TO R410A
R32 IS NONEXPLOSIVE
AND HARDLY FLAMMABLE.
R32 is technically classified as a "mildly flammable" gas by the EPA. However R32 is
extremely difficult to ignite, non-explosive, and the least toxic of all the Class A refrigerants.
The regulatory warning labels on Penguin Chillers are EPA mandated for all refrigerants
considered flammable which covers a wide range of refrigerants including mildly flammable
refrigerants like R32 as well as highly flammable gasses such as butane (R600) and
propane (R290). When it comes to label requirements there is no distinction made between
mildly flammable and highly flammable. These regulatory warnings can be a bit intimidating,
they are there to keep you informed, but they should not lead you to worry about the use of
our chillers in normal operation. Our Chillers are intended for indoor use.
This information is based on reports prepared by the Air-conditioning and Refrigeration Equipment
Manufacturers Association of Australia (AREMA) and the Consumer Electronics Supplier Association (CESA)

When first receiving the chiller AND anytime the
chiller is moved without keeping the unit level, you
MUST let the chiller remain upright for at least 2
hours before plugging it in.
Urgent Notice
Failure to do so will
result in chiller damage.

COLD THERAPY WATER CHILLER SETUP
Chillers work on the principle of moving heat from one spot to another. In the case of a
water chiller, its job is to move heat from the water out into the air. This means proper air
flow is critical to the operation of a chiller. If the chiller is located in an overly hot or
unventilated area, it cannot dissipate the heat efficiently therefore lowering the chiller's
ability to cool. Unless properly modified, enclosed spaces like small cabinets or closets
will heat up quickly and won't provide enough ventilation for the chiller to properly do its
job. If the chiller's hot exhausted air is being recirculated back into its intake grills, then
the chillers BTU/hr capacity is greatly reduced. It is recommended to have at least 12” of
open space on all sides of the chiller to allow for proper ventilation.
Power
Locating the Chiller
1.www.PenguinChillers.com
Connecting Your Chiller
The chiller features 2qty camlock fittings to mate with fittings on the back of the chiller.
The camlock fittings have 3/4″ barbs for connecting 3/4″ ID tubing to the chiller. (Tubing
sold separately if not purchased in one of our packages).
Follow the Inlet/Outlet flow pattern as marked to ensure the chiller functions properly.
Take your tubing with the in-line filter and Banjo Cam Lever, put it over the quick
connect fitting, and pull the levers towards you. Ensure the arrow on the in-line filter is
pointing towards the "Inlet" of the chiller.
- See video for demonstration on how to connect to the chiller.

After you secure the camlock fitting in place, remove the metal pin
(not in the video) and put it through the hole on the camlock fittings itself to ensure you
have a good hold.
Our cold therapy water chiller has a GFI plug. It's suitable to plug into a 110v - 120v 15a
outlet (standard household outlet) It is recommended to plug directly into a receptacle.
Power strips should be avoided. If an extension cord is necessary we recommend using
a 12 awg cord with single end (not a multi tap). Once plugged in, be sure the GFI is in
the reset position.

Flow/Filter:
The Cold Therapy Chiller has a built in pump, so no need to worry there.
***Please note your setup needs to gravity prime to the pump, the pump is not capable of
self priming/suction. Place the chiller within 3′ of the drain of your tub, the bottom of the
chiller should be at the same or lower height compared to the bottom of your tub – do not
elevate the chiller above the tub. An overly long tubing run from the tub drain to the
chiller inlet may cause the pump to fail to move enough water.
If you have a setup where gravity priming your pump is not an option, you will
need to manually prime the line. You can do so by filling the tube going to the "inlet" of
the chiller with water. Once the tube is completely full, take the palm of your hand and
place it over the opening of the tube. You can then take the tubing and put it under
water. At that point, you can release your hand, and your line is now primed. (Make sure
to fill the tube all the way to avoid air getting in the line). See video explanation here:
Here
When you go to fill your tub with water, try keeping the water level just below where the
water comes back into the tub. The pressure of the water over the opening makes the
pump work harder to push the newly cooled water through.
We recommend to check both filters on a weekly basis and ensure they don't get too
dirty. How often you need to clean your filter will depend on a number of things.
Weekly usage amount, personal hygiene, outside environment, etc.
- i.e. if you are in an area with a lot of pollen, you may need to clean your filter more
regularly then someone who doesn't.
(To properly insert the larger filter, you will take the concaved side and push it into the
top of the filter cap. You then take the blue filter housing and screw it around the filter.)
Just make sure to note of your flow rate when you first hook up the system. If you notice
your flow rate slowing, this means it’s time to clean out your filter. Do not run the chiller
without flow.
If you do not clean your filter on a regular basis and it leads to slow/no flow, you
will damage the chiller. Penguin Chillers will not be responsible for damage
caused from improper care of the chiller.
Chiller Maintenance
To clean the internals of the chiller, you can use white vinegar and hot water. Fill a
bucket with 1-2 gallons of white vinegar with hot water and recirculate it through the
chiller for a couple hours.
The Cold Therapy Chiller is weather rated, but only above freezing ambient
temperatures. If you are in an area that gets to 32F or lower, the chiller needs to be
unplugged, drained, and stored for the season. To drain the chiller, you will want to hold
it upside down with the inlet/outlet ports pointing to the ground.

Troubleshooting
Does the chiller LCD have power? (check GFI plug if not)
Is there a LED/Working Light symbol that is lit up on the controller?
Does the Compressor come on?
Is the controller readout steady or does it jump around?
Is there a noticeable amount of air coming out the right side of the chiller / air is not
blocked/ coil not clogged?
Is the air coming out the right side of the chiller warm/hot OR room temp?
My Chiller isn't cooling:
If there is no light indicating the controller is calling for cooling,
check controller settings.
If warm air is coming out the back, the chiller is cooling, at least partially. The question
becomes why is it not working to your expectations / it's full potential.
When you set the temperature on the controller, ensure that the clear cover is opened.
View the controller manual here: Controller Manual
The controller constantly monitors your systems incoming water temperature.
When your systems water temperature moves above your desired set point, the controller
tells the compressor to turn on and begin cooling the water. Once your desired set point
temperature is reached, the compressor turn off. - The fan will only come on as need be to
cool the unit depending on ambient temperature.

Chiller Maintenance Cont'd
If your chiller is left outdoors below freezing ambient temperatures without being
drained and damage occurs, Penguin Chillers is not liable for the damage. It can be
returned to our facility for repair, but will not be covered under warranty.
The left side coil of the chiller can become dusty/dirty overtime. If it's dirty enough to reduce
airflow, the cooling capacity of the chiller will be reduced. Regularly using compressed air to
blow the coils off will keep the chiller performing as efficiently as possible. If the setup is
outdoors, you can take a regular garden hose and spray off the coils.
The frequency of these cleanings highly depends on your operating environment. Yearly coil
cleaning for indoor setups should be sufficient for most users, however, if you know you are
operating in a particularly dusty/dirty environment, or outdoors, then you'll want adjust your
cleanings accordingly.

Troubleshooting Cont'd
Have you verified that the water isn't being cut off by a dirty filter?
If there's a valve on the drain of the tub, make sure it's fully open.
Unplug the chiller (never leave plugged in if you don't have flow).
I'm not getting water flow back into my tub/tank.
With the chiller being unplugged for at least 30 minutes:
- Take the filter out of the housing, put the housing back on empty.
- Undo the fitting at the inlet of the chiller, there should be very good
gravity flow of water, reconnect fitting on the inlet.
- Take the fitting off the outlet, ensure there is good gravity flow here as
well, then reconnect.
- Disconnect the fitting at the filter connection, move the tubing down to
the ground, water should be flowing, plug the chiller in and water flow
should begin to increase, you can then reconnect the fitting to the filter.
If you have any issues where you aren't getting water when
disconnecting the fittings, please state at what point in the process
you are not seeing the gravity fed water. (Inlet, outlet, filter hose, etc.)
Check the water temperature with an external thermometer
Ambient air temperature.

(not an IR gun). It is possible that the water is cold and the controller is providing an
incorrect reading.
When referring to a Temperature, please clearly identify what the specific sources are.
There are many sources of temperature, clearly identifying which temperature you are
referring to is critical to an accurate and speedy assessment of the issue.

Cost To Run
At $0.12/KWh the monthly cost of operation should be around $18-$28/month. The
compressor and fan only turn on when cooling is needed, once the water reaches your
set point they turn off and only the low wattage pump continues to run.
Cold water keeps bacteria (slimy walls) largely under control by slowing or
If you are using it on a regular basis the amount of potential power savings
When you cut power to the chiller you also cut power to the pump.
A common question we get revolves around setting the chiller up on a timer.
Ideally you’ll want to keep the water cold at all times. There’s a few reasons for this –
stopping their growth. This significantly reduces the amount of maintenance
needed to keep your water clean for longer periods of time. This means less
frequent water changes and that much lower levels of sanitizer being an
effective dose (chlorine/hydrogen peroxide/etc).
will be fairly insignificant, the heat it would gain in the “off” period still needs
to be removed when you turn it back on. So if running normally costs
$18-$28/month you might be able to save $3-$5/month. However, you'll have to
change water more often so it is unlikely to be a net cost savings.
Pumps get the most wear and tear during startup, that’s when a pump is most
likely to fail as well. Cycling the power to the chiller is just adding unnecessary
wear and tear to the pump.
Additional Information
Troubleshooting Flow Cont'd
If the above mentioned steps did not work, try removing the fitting that's
going up to the filter housing.
Take a garden hose and put it up to that tubing line (leading to the filter), and
flush the system backwards. Once you do so, you will see air bubbles coming back up
into your tub. You can flush the system for 15-30 seconds or so until you stop seeing air
bubbles coming into the tub. Once you stop seeing the bubbles, re-connect the tubing
line to the filter housing and turn the chiller on.
