11) Wax is too hot for patient and the unit is at lowest possible
operating temperature (126°F or 52.2°C):
Either different wax needs to be purchased with a lower melting
temperature or a temperature acclimation procedure can be
followed. This procedure involves dipping the patient's hand from
the fingertips to the first knuckle and waiting about ten seconds for
the wax to cool. Next, dip the patient's hand from the fingertips to
the second knuckle (proceeding to cover up the first layer of wax
and effectively insulating the hand from some of the heat).
Continue to build the wax up incrementally by small amounts.
OTHER USEFUL INFORMATION:
Model S is an old reference to current models PB-101 and
PB-107
Model K is an old reference to current model PB-104
Model BB is an old reference to current model PB-105
Model H (no longer being manufactured) is referring to an old
PB-104 without a drain.
The sanitize mode on the PB-104, PB-105, and PB-107 are
turned on with a timer.
The sanitize mode on a PB-101 is turned on with a three- way
switch.
All Dickson models have a sanitizing circuit.
Standard operating temperature is 126° to 130°F (52.2° to
54.4°C)
Lowest operating temperature is 126°F or 52.2°C. Below this
temperature, wax will harden (if lid is removed from the unit or
power is off)
A capillary thermostat is attached to the temperature control.
This device controls the temperature with a mechanism that
involves a tube filled with oil. The temperature heats up the oil
in the capillary, and the hotter it gets, the higher the oil rises up
the tube.
There are 2 overheating sensors in all models except for the
PB-101. The L-145 is the low limit overheating sensor. This
sensor will turn the unit off when it gets in the range of 145° to
155°F (62.8 to 68.3°C). The other overheating sensor is for the
sanitize mode. This sensor will not allow the unit to go past
200°F or 93.3°C.
Timer is only to be used to turn on the sanitize sequence
in which the temperature of the wax will approach 200°F or
93.3°C. All units except for the PB-101 are simply turned on
by plugging them in. The PB-101 has a switch.
Dickson Paraffin Bath FAQ
1) Breakers kick out when paraffin bath is plugged in:
If fuses in paraffin bath did not also blow out, there is too much load
on breaker. Try another electrical outlet.
2) Fuses blow when plugged in:
There is a dead ground in the unit. The unit must be opened up for
repairs.
3) On/off light does not turn on when plugged in:
First check the fuses to see if they are blown. Next, check the circuit
breaker on the building to see if it has been tripped. Third, the green
light may be broken.
(For PB-104 & PB-105: 6902-135-000 and for the PB-101 & PB-107:
6902-122-000)
4) On/off light is dark even though the paraffin bath is plugged in
and is melting wax properly:
The green light (see No. 3 above) is no good or has been wired
wrong.
5) Paraffin bath gets hot enough to get to the sanitize (high heat)
temperature, melts the wax, but won't cool down:
Bad high-temp overheating sensor (6903-144-000 or L-200) or the
timer could be stuck (6902-348-000)
6) Bath will not get to the sanitize temperature:
Bad low temp overheating sensor (6903-146-000 or L-145) or
bad high temp overheating sensor (6903-144-000 or L-200) or
heating element needs to be replaced (see parts list). It is also
possible that the unit has been wired wrong.
7) Bath goes to high, 200°F+ or 93.3°C+ but proceeds to cool
down to room temperature
Check adjustable operating thermostat on the back of the unit
(PB-101 & PB-107) or remove front cover (PB-104 & PB-105) and
make sure it is turned all the way clockwise. If the temperature does
not rise in 1 to 2 hours, the heating element (see parts list) is bad or it
has been wired wrong . Also, the unit may have a bad capillary (6902-
140-000)
8) Timer is stuck:
Remove the knob, loosen the nut slightly and try the timer again. If it
still is stuck then the timer is bad (6902-348-000).
9) Wax is not melting all the way:
The wax in the paraffin bath must reach 200°F+ or 93.3°C+ when
melting the wax for the first time. In order to fully be sure that the unit
has reached the proper temperature, make sure the timer has been
through at least 2 cycles (3 cycles for larger units). If the wax still does
not melt, then the wax may be bad.
10) Old wax not melting properly and hardening over time after
continual reuse:
If the wax is at a temperature range of 127° to 130°F (52.8° to 54.4°C)
and has been continually reused for months, then it is likely that the
oil content has been depleted from the wax. Add oil or get new wax. If
the wax in the bath is partially melted then a new heating element is
not needed. If the wax goes completely solid, then they will need a
new heating element. (see parts list).
