page 5) and follow the procedure for replacing the S.A.S. Assembly, page 7.
Note:
If the unit does not heat up at all and you are unable to remove the paraffin, the
S.A.S. Assembly can be replaced with the solidified paraffin left inside the bath.
Removing the Paraffin or Mineral Oil
CAUTION:
Do not pour liquid paraffin or mineral oil out of tank, as some will run down
the joint between the tank and the lip of the case, causing the unit to deteriorate and fail.
Do not use a glass or metal cup to empty the tank as these may scratch the surface of the
tank, causing it to corrode.
Removing Mineral Oil
• If you have used mineral oil to test your
Therabath
®
Pro
,
™
use a plastic or paper cup to
empty it. Fill the cup by dipping it in the mineral oil, then emptying the cup into your
container of mineral oil. When the bath is nearly empty, you can tilt it on its side so
that it is easier to remove the last cupfuls of the oil. After you have emptied as much as
you can with the cup, soak up the residue of oil and wipe the tank clean with paper
towels.
• Be sure to avoid dripping mineral oil on the seam of the tank and the case, so that oil
does not enter the inside of the unit.
Removing Paraffin Wax
• If you have used
Theraffin
®
paraffin to check the operating temperature, and the oper-
ating temperature of the unit is correct, the unit can be left on for normal use.
• If the unit is working correctly but you need to relocate the unit, or if testing dictates
replacement of the S.A.S. assembly due to an improper operating temperature, the
following method should be followed for removing the paraffin:
•
Remove the grille from inside the tank (if present).
•
Unplug the
Therabath
®
Pro
™
and allow the paraffin to solidify overnight.
•
After the paraffin is solid, plug in the unit for a few minutes, or just until the cake
of paraffin loosens from the sides and bottom of the unit.
•
After the paraffin is slightly loosened from the sides, unplug the unit.
•
Press down firmly on one end of the paraffin, tipping the opposite end up. Then
lift out the cake of paraffin. Be careful to avoid dripping.
•
Blot up any remaining paraffin in the tank with paper towels. If any solidified
paraffin remains inside or on the outside of the unit, soften it carefully with a hair
drier or heat gun, and blot it with a paper towel.
•
Clean the unit with a soapy cloth, and rinse with a clean cloth wrung out in hot
water. Then wipe the unit dry.
