MAKE-UP PROCEDURE:
1)Into a separate and clean tank, hot water is filled up to approximately 60 % of tank working volume.
2)While stirring, add slowly and carefully the required quantity of Nickel Chloride into the water. (Attention !: Nickel Chloride must be fully dissolved!).
3)While continue stirring, add slowly and carefully the required quantity of Boric Acid into the water. (Attention !: Boric Acid must be fully dissolved!).
4)While further stirring, add slowly and in small quantities the required quantity of Nickel Sulphate into the water. (Attention !: Nickel sulfate must be fully dissolved!).
5)Add approx. 0.5 oz/gal of activated Carbon powder into the solution and stir for at least 30 minutes, then stop all agitation and allow carbon to settle down.
6)Filter the solution through a 5 micrometer mesh filter media into the working tank. Make sure no active carbon particles are in the working solution.
7)Top working tank with water up to operation level and switch on air agitation
8)Measure and adjust the pH with diluted (1:10) Sulfuric Acid to operation range (3.0 to 3.5 - optimum 3.2.)
9)Add the necessary quantity of HP SUREGUARD HSadditive.
10)Switch on circulation filter pump. Do not use air agitation for operation as air consumes additives by oxidation.
11)Adjust operation temperature to operation range (115oF to 130 oF - optimum 120oF)
12)Dummy plate for approximately 4 ampere hours per gallon.
Solution is now ready for start up.
MAINTENANCE:
Additions of the of the HP SUREGUARD HSand theHP SUREGUARD WAare typically added according to Ampere hours. Although exact dosing rates should be calculated according to practical experience gained on site and continuous measuring results of electro-potential with a S.T.E.P. tester
Additions of HP SUREGUARD HSshould not exceed 0.5 ml/l at any one time. (i.e small doses are recommended).
Regular additions of HP SUREGUARD WAis optional.
Consumption(nominal) per 10,000 amp/hours:
HP SUREGUARD HS1.5 to 2.0 gallons
Hull-cell tests are recommended to control performance. (2A, 5min, 120oF, air agitation)

OPERATING CONDITIONS:
Agitation / Necessary - preferably mechanical(air agitation consumes Hi- S additive due to oxidation).
Filtration / Continuous, 1 to 2 tank volumes per hour throughput, with 5 to 10 micrometer mesh filter media.
Cathodic current density / Optimum 10 A/ft2, maximum 12 A/ft2
Temperature / 115oF to 130oF
Anodes / Bagged Nickel anode pieces in Titanium baskets
Plating time / Minimum 2 minutes at 10 A/ft2
Tank ventilation / Necessary
TROUBLESHOOTING:
Problem:Too small electropotential difference to bright nickel is caused by lack of HP SUREGUARD HS.
Correction:Add approx 0.05% to correct and measure S.T.E.P. again until desired result is achieved.
Problem:Too high electropotential difference to bright nickel is caused by excessive addition of HP SUREGUARD HS or too low pH.
Correction:Stop additions and insufflate air to reduce the content or allow pH to rise to approx 3.0.
