between the red and white wine compartments! Use a maximum of 1/4 turn adjustment, while waiting a
minimum of two hours between adjustments.
7. Where do I find the filter screen, and how do I clean it?
The Magnum refrigerator air intake filter screen is located on the back of the cabinet on all rear-venting
units. Front venting units do not use a filter screen. Once the filter screen is removed from its retaining
clips, it can be cleaned in any conventional dishwasher. Dry the filter before re-installing.
8. Why is my unit having a cooling problem?
Most Magnum cooling problems on new units are caused by inadequate air ventilation or improper
thermostat settings. Unless specified to the contrary by the purchaser, WineKeeper sets all Magnum
refrigeration units to run at approximately 42
o - 45 o Fahrenheit. If you need to change this slightly, see:
"Thermostat Adjustments for Magnums" on the technical information page. For adjustment of more then 5-
10
o degrees, contact WineKeeper. Adequate vented air space for a Magnum is: 3-6" behind, 12" above
and 1-2" each side, minimum. If a new unit is not cooling correctly, follow these instructions before
adjusting the thermostat. (A new unit can take up to six hours to cool down to its operating temperature.)
While running, note the temperature on the digital display, then move the Magnum so as to increase air
ventilation dramatically. Let the unit run for one hour. If the temperature has dropped, the problem is
ventilation. If the temperature does no drop, verify that both fans on the refrigerator are operating (one
fan blows air into the bottle compartment out the top of the white grate, the other fan blows air out the
top vent at the rear of the Magnum. If these are both operating, call WineKeeper for further help. On
older units, follow the steps above, as well as removing the filter screen on the rear of the unit, this screen
may be dirty, and may need to be cleaned. If these steps do not work, unplug the unit for two hours, then
reconnect and note results. If this fails to fix the problem, call WineKeeper for further instructions.
9. What kind of regular maintenance should I perform on my unit?
Visually inspect the latex rings on each stopper assembly for wear or splits. Replace as needed. Inspect all
O-rings on the inlet and outlet sides of the regulator and any quick disconnect fittings on your unit.
Replace when showing signs of wear or cracking (silicone lubricant or mineral oil applied to these O-rings
will increase their longevity). Clean all parts that come in contact with the wine every 4 weeks (see
cleaning instructions). Replace the white pinch clamps as needed.
10. How do I replace my stopper assembly?
You must first be sure to pinch off the nitrogen pinch clamp and release pressure from the wine bottle,
then remove the complete assembly from the cabinet by loosening the hose clamp using either a slotted
screw driver or a 1⁄4" socket or nut driver. Pull the wine tube (with the hose clamp still connected) off of
the stainless steel siphon tube that passes through the stopper assembly. Pull off the 1⁄4" O.D. nitrogen
supply line from the brass fitting on the rear of the stopper assembly. (Before replacing this tube on the
brass fitting later, you may need to cut off approximately 3/8" so that you will have a tight connection).
Now that you have completely removed the stopper assembly from the cabinet, grab the stainless tube at
the bottom where it is bent, and pull it out of the stopper assembly. Insert the stainless tube into the new
stopper assembly, use a little water to lubricate the first 3"- 4". Simply reverse above steps to re-install.
11. Which gas is better for my WineKeeper unit, nitrogen or argon?
Nitrogen, which comprises approximately 80% of the air we breathe, is inert (it has no odor, taste or
color, and displaces oxygen). Argon has similar properties, but is slightly heavier than air and tends to
form a blanket between the surface of the wine and any air trapped in the bottle. Neither gas has any
