Removing Coolant:

a. Drain coolant from the reservoir using clean siphon- ing equipment

b. Coolant level should be drained below the strainer- pressure fitting:

•This prevents coolant from streaming out of unit when strainer nut is removed

SERVICE THE PUMPS INLET STRAINER:

a. Place absorbent towels underneath pump head to prevent stray coolant from wetting coolerʼs electrical components.

b. See figure 7. Hold pump head to apply counter torque when loosening strainerʼs 7/8 acorn nut. Do not confuse with 3/4 acorn nut. Remove nut and slide inlet strainer down and out from pump head.

c. Inspect strainer for damage or excessive clogging:

•Replace or Gently rinse strainer under running water to thoroughly clean it.

d.Use a mirror to inspect inside of pump for contami- nation. If hardened debris is present and interferes with filter seating, carefully remove it with dental pick without scratching inside of the pump. Use care not to drop debris into pump.

e.Reinstall strainer and acorn nut, tightening with 34±15mm-Kilograms( 75±15 in.-lbs.) of torque.

•Hold pump head to apply counter-torque when loosening strainers 7/8 acorn nut.

f.Wipe dry all areas wetted by coolant. Dispose of towels in an environmentally responsible manner.

Add coolant:

a. Add 7.6 ltr. (2 gal.) of coolant, either the recommen- dations off the water cooled accessory or if none, see the design specification summary listed in this manual.

ADDITIONAL SERVICE NOTES:

1.Always use a back-up wrench on pump head when loosening or tightening pump fittings.

2.Never run the pump dry. Always use a recommend- ed coolant, otherwise pump damage may result.

3.Flush coolant from system and replace with fresh, recommended coolant at least once a year. More frequent flushing may be necessary, depending upon the userʼs particular system or its usage, especially if it is prone to clogging from biological growth in the coolant.
