Brookfield Bath, Model TC-101 Digital KU-1 Viscometer - Manual (Page 10)

Section 3. Maintenance
3.1 Heater
The heater should be kept clean. If deposits build up on the heater they may be removed by scouring
with a non-metallic (plastic) abrasive pad. Do
NOT use steel wool, it causes stainless steel to rust.
3.2 Pump Motor
The top and bottom bearings are permanently lubricated with a high temperature silicone grease.
They should not require lubrication. The pump motor bearings are not available separately. If the
bearings become noisy, we recommend replacement of the entire motor to save cost in labor and
retain reliability. A replacement pump and motor mounting kit is available.
3.3 Condenser and Air Vents (Refrigerated Models)
The condenser and the right and left air vents should be kept free of dust and dirt. Dirt thermally
insulates the condenser and reduces the cooling capacity of the refrigeration system. Set up a periodic
schedule to clean the fins of the condenser with compressed air.
3.4 Cleaning
Use only mild detergent and water or an approved cleaner on the painted and stainless steel surfaces.
Do not allow cleaning liquids or sprays to enter the controller head vents.
3.5 Maintaining Clear Bath Water
Optimum temperature and moisture conditions for algae growth exist when using water as the bath
fluid. To prevent algae contamination and to minimize frequency of draining the reservoir, an algicide
should be used. Do NOT use Chlorine Bleach.
Section 4. Troubleshooting
4.1 Unit Disabled - Service Required
• Check the power to the unit. • Be sure circuit breaker is on. • Try unplugging the unit and
plugging in again to fully reset the system. • If the unit continues to display an error message or no
message, request service.
4.2 No Pumping
• If the pump motor does not spin, check the Hi-Lo pump speed switch is all the way up or down. If it
is in the middle, the pump will not receive power. • Check the pump impeller turns freely. • Check
fluid level of the bath to be sure the pump head is covered with fluid.
4.3 Insufficient Pumping
• Check for low line voltage, especially when the heater is on. • Hose diameter may be too small.
• Fluid viscosity may be high.
