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.
