To insure proper and automatic safety valve
operation: DO NOT connect a shut off valve or a plug at
safety valve outlet. DO NOT connect a shut off valve or any
construction in steam supply pipe.
Steam Outlet (1⁄2"NPT)
1. Do not install any valve in steam line. Flow of steam must
be unobstructed.
2. Use 1⁄2inch brass pipe or copper tubing from unit to
steam head as permitted by codes.
3. Insulate steam line with fiberglass pipe insulation or similar
insulation rated 212° F or higher.
4. Pitch steam line 1⁄4" per foot towards steam head or steam
generator to avoid valleys and trapping of condensate.
IMPORTANT NOTES:
• Running the steam line down and then up will create a
steam trap blocking the flow of steam.
• A 1.5" hole in the steam room is required to mount the
steamhead.
Water Quality Information
For optimum results, the water supply should be tested prior
to installation. If the mineral content exceeds the following
recommended limits, various external treatment processes are
recommended to correct the problem.
NOTE: An analysis of the on-site water must be made by a
recognized and reliable water treatment company to ascertain
the existing condition and treatment required.
Poor water quality can affect efficiency or result in steam gen-
erator damage. Water contains impurities in solution and sus-
pension. These impurities concentrate in the generator. The
concentration of these impurities increases as more feedwater
is introduced into the generator and steam is produced. If the
suspended solids are allowed to concentrate beyond certain
limits, a deposit or “scale” will form on the generator internal
surfaces.Thisdepositcaninterferewiththepropergenerator
operationandcausegeneratorfailure.Theconcentrationof
theseimpuritiesisgenerallycontrolledbythewaterquality

IMPORTANTNOTE:
•
•
Do not disassemble steamhead , steamhead is shipped fully
assembled and requires no additional assembly.
To preserve steam head nish, do not use wrenches or other
tools to tighten. DO NOT use abrasive cleansers or chemicals.
Use only water with mild soap and anon-abrasive sponge.
Because the steam head and direct steam emissions are very hot,
locate the steam head where incidental contact by bather with
the steam head or direct steam emission cannot occur.

TROUBLESHOOTING
Step 1 Check main incoming power to the unit.
Step 2 Ensure the black wires from the pri-
mary side of the transformer are connected
to the quick connect tabs on the line side
of the contactor.
Step 3 Verify that you have 24VAC
coming out of the transformer, WHT &
WHT/BLU wires, into the board.
Step 4 Verify that you have the
green light on the PC board.
Step 5 Push the white test button to
run the generator for 10 minute test
cycle. Make sure the steam room is
empty.
Step 6 Verify that you have 24 VAC to the water feed
solenoid, GRY & WHT/GRY wires (will fill when needed).
Step 7 Temporarily short out the WLS (Purple wire) and
GND (Green wire) terminals and verify the contactor
engages.
Step 8 When the red light is on, verify 24 VAC,
RED & WHT/RED wires, to the contactor.
Step 9 Check main voltage on the
load side of the contactor when it is engaged.
Step 10 If all steps on the power path were verified, turn
off power to the unit and pull the heating element via
the left hand access panel for inspection.
DO NOT disassemble internal components,

Care
Entretien
To clean your Aquabrass faucet or accessory, wash with a wet nonabrasive soapy cloth. Then wipe dry with a soft towel or cloth. We
recommend this be done on a regular basis.
DO NOT USE ANY ABRASIVE, CHEMICAL OR CORROSIVE, POWDER OR ANY OTHER STRONG CLEANERS INCLUDING DETERGENTS,
WINDOW CLEANERS AND DISINFECTANTS ON YOUR Aquabrass PRODUCT as they will destroy the finish and therefore VOID THE
WARRANTY.
Toothpaste remnants should also be rinsed off when necessary. Ask your plumbing retailer about our PROTECTANT-CLEANER now
available from Aquabrass. This product is specially manufactured to clean and polish leaving a protective coating to maintain your
product’s shine and finish.
Pour nettoyer et conserver l’apparence de vos robinets ou accesoires Aquabrass, lavez-les avec un linge mouillé à l’eau tiède et
enduit d’un savon doux non-abrasif. Puis essuyer avec un linge doux et sec. Nous vous recommandons cet entretien sur une base
régulière.
NE JAMAIS UTILISER DE PRODUITS ABRASIFS, CHIMIQUES, CORROSIFS, INCLUANT DE TRÈS FORTS DÉTERGENTS, EN LIQUIDE OU EN
POUDRE, NETTOYANTS POUR VITRES ET DÉSINFECTANTS sur votre produit Aquabrass. Cela pourrait en détériorer le fini et ANNULER
LA GARANTIE.
Les restants de pâte à dentifrice doivent aussi être rincés au besoin. Demander à votre détaillant le PROTECTEUR NETTOYANT
Aquabrass spécialement conçu pour nettoyer, faire briller et protéger en laissant un mince film protecteur sur vos robinets et vos
articles décoratifs.
