D-2 MAINTENANCE D-2
Prepare the disinfectant:
Make a quantity of only what is needed to avoid an
excess Bulk preparation (for coolers serviced in quan-
tity):
5.7L (1.5 gals.) of pure, fresh water per cooler and
1.0ml of additive per cooler. Example: for 100 coolers,
add 100 ml to 150 gals. of pure fresh water, Pour 5.0L
(1.3 gals.) of disinfectant into the empty reservoir.
Recap the reservoir. Prime the cooling system by
positioning cooler horizontally and circulate disinfec-
tant through it for 10 to 15 minutes. Drain disinfectant
from the cooling system. Do not reuse this solution.
Add new, fresh coolant to the cooling system. Add 1L
(0.3 gals.) of fresh disinfectant to the system by pour-
ing it into the reservoir, then reduce the concentration
to the nominal 30 ppm:
Add the balance 4.0L (1.0 gals.) of fresh, pure water
to the reservoir to create the treated coolant concen-
tration. Prime the cooling system.
Check coolant level. Add more fresh, pure water if
required, without adding more than 0.3L (0.1 gal.) of
pure water to prevent diluting the coolant additive.
Procedure and Preparation:
• Always disconnect the COOL ARC® 35 machine
from service input power by disconnecting the
V310-T/V311-T from input power.
• Always allow the coolant in the system to cool
enough to avoid burn injuries.
• Avoid contact with contaminated coolant. Wear
waterproof gloves and protective eye wear.
