The LC65 glycol bath capacity is 7.5 gallons (US). The LC85 and the LC86 glycol bath capacity is
14.8 gallons (US). The LC44 and LC47 glycol bath capacity is 16.25 gallons (US).
Glycol supplied by Glastender, Inc. may be diluted to a ratio of (1) part glycol to (2) parts water for
freeze protection down to 0ºF (-18ºC) or a ratio of (1) part glycol and (3) parts water for freeze protec-
tion down to 10ºF (-12ºC). These mix ratios are recommended, since the refrigeration system is not
capable of lowering the temperature of the glycol bath below 15ºF (-9.4ºC)
For glycol not supplied by Glastender, Inc. please consult the glycol manufacturer’s recommended mix-
ing ratio for the desired operating temperature.
NOTE: Do not place full strength glycol (undiluted) in the bath, as it will reduce the efficiency
of the refrigeration system and may result in damage to the recirculation pump due to
increased viscosity of cold glycol.
NOTE: Select and use only a propylene glycol product that meets FDA (Food and Drug
Administration) regulations as a food grade product. Any substitution of food grade
glycol with automotive anti-freeze or other products will expose people to hazardous
chemicals.
Fill the bath with glycol mixture by placing funnel in the fill hole (remove black plug in refrigeration
deck platform). Pour in the glycol mixture until the level in the bath reaches the top, and the liquid
begins to flow slightly from the overflow tube at the front of the unit.

• Plug in unit to fifteen (15) or twenty (20) amp protected circuit (Refer to Step 3, Electrical Hook Up).
• Models LC65 and LC44 have a power switch that allows the condensing unit and recirculating pump
to operate when is the on position.
• Once models LC85 and LC86 are plugged in, the condensing unit will operate. There is a separate
power switch to operate recirculating pump.
• Once the LC47 is plugged in, both the condensing unit and the recirculating pump will operate.
• Check all glycol circuit line connections for leaks.
• Once the pump has operated for a few minutes and the glycol circuit lines are fully flooded, the bath
will need to be topped-off with additional glycol mixture.
