NOTE: Do not turn the inner stem.
The Hydrocollator units operate through the use of a hydraulic capillary-type thermostat and can be left
plugged in and turned "ON" to provide a ready supply of heated HotPacs™.
The HotPac rack is adjustable and accommodates different sizes and types of packs.
SS Unit – Holds eight Standard Size packs. Special rack holds two Neck Contour packs.
E-2 Unit – Adjustment is accomplished by inserting the hanging platform. The E-2 unit comes complete
with two oversize, three Standard Size packs and one Neck Contour pack.
E-1 Unit – Adjustment is accomplished by placing the rack insert in or leaving the insert out. With the
insert in, the rack accommodates four Standard Size packs.
INDICATORS AND CONTROLS
GREEN LAMP (220/240 volt units), when illuminated, indicates that main power is connected, the
switch is ON and unit is operating.
RED LAMP (if applicable), when illuminated, warns of an overheat/low water condition. Action is
necessary to rectify the condition.
IMPORTANT: Some models are fitted with a thermal cut-out thermostat which acts as a “Non self-
resetting” thermal cut-out. In the unlikely event of a fault condition occurring, this device is designed to
open the power circuit between 180°F to 185°F (82°C to 85°C). It is NOT possible to alter its operating
range. The operation of the unit may be restored by depressing the red button after the water/element
temperatures have been allowed to cool. If the fault condition persists, please contact Chattanooga
Group, Inc. or an authorized agent.
