SECTION 5: GENERAL MAINTENANCE 24 Manual 0-2530
B. Coolant Filter Maintenance
The Ultima-150 has three filters in the cooling system: the
Coolant Filter Assembly, the In-line Filter Assembly, and
the Reservoir Filter (Coolant Reservoir Deionizer Basket &
Bag). As part of general maintenance, or if the system
performance is diminished, check or clean these filters as
needed.
1. Coolant Filter Assembly
The Coolant Filter Assembly should be cleaned pe-
riodically. Remove the filter screen by unscrewing
the filter retainer from the Coolant Filter Assembly.
Clean the filter screen by rinsing with hot soapy
water. Remove the soap residue by rinsing with
hot clean water. Be sure that all the soap is re-
moved and the screen is dry of water before rein-
stalling the Coolant Filter Assembly.

riodically. To gain access, remove Enclosure Cover.

and remove the filter retainer from the filter hous-
ing assembly. If the In-line Filter is suspect, clean
the filter screen by rinsing with hot soapy water.

water. Be sure that all the soap is removed and the

NOTE
Protect the power supply from coolant spill. Place a
rag under filter housing when cleaning filter screen.
3. Reservoir Filter Assembly
Make sure there is always a Deionizer bag in the
Reservoir Basket. Check the condition of the
Deionizer Bag - if the complete bag is yellowish
brown then replace the bag.
C. Cooling System Maintenance
1. Coolant Level
The coolant level should be checked every day. If
the coolant in the Reservoir is more than 2 inches
(50 mm) from the top of the reservoir, then add Ther-
mal Arc
® Torch Coolant.
CAUTION
Do Not introduce tap water into the coolant system
or electrolytic corrosion will occur. Use only Ther-
mal Arc
® Torch Coolant.
