Low Level Switch
(Option)
The level switch protects the pump in the event of accidental fluid loss. Since this switch is
"passive" during normal operation, it is advisable to check it every 6 months. Open the tank
cover and push down on the switch to see if the low level alarm is activated.
Algae
Boyd recommends the use of an algae inhibitor to prevent growth in the reservoir.
Cleaning the System and Reservoir
1.
To clean the system drain the unit and replace the coolant with clean water.
2.
Run the unit with the clean water.
3.
Drain the unit again.
4.
Replace all filters.
5.
Refill unit with either water or a water and freezing point depressant.
Pump Motor Lubrication
Positive displacement pump motors use sleeve type bearings with large lubricant reservoirs.
Oiling instructions are posted on each motor. In the absence of instructions, add approximately
30 to 35 drops of SAE 20 non-detergent oil to each bearing on the following schedule (SAE 20
= 142 CS viscosity):
Duty Cycle
Oiling Frequency
Continuous
Once every year
Intermittent
Once every 2 years
Occasional
Once every 5 years
Pump Strainer
Periodically inspect and clean the positive displacement pump strainer. If it becomes fouled
flow rate will decrease and the pump may wear prematurely.
