BEFORE INSTALLATION
Installation must be carried out in accordance with the current edition of the local wiring regulations code having jurisdiction. Installation should be performed only by a qualified electrician.

| The hand dryer is to be installed with a hardwired stub provided in advance of installation by others.
See MT for a complete reference to mounting heights and power KO locations.|
---|---|---
| It is recommended to avoid installation of the dryer near high reflective objects
(mirror, stainless steel washbasins, etc.) in order to avoid faulty function of the
presence sensor.

INSTALLATION

1. Make sure the power supply breaker is switched off. Installation must adhere to the regulations of the current edition of the local wiring code having jurisdiction. Installation should be performed only by a qualified electrician.

2. Place template against the wall at the desired height (see mounting height recommendations on MT) and mark locations of four(4) mounting holes and wire service entry at the knockout (KO) location.
   Note: For two(2) or more dryer units, units should be no closer than 610MM[24″] on centers.

3. Remove and retain 2 cover screws and cover.

4. a. For in-wall (concealed) power supply-
   Provide supply wire to KO location according to local code and attach securely to chassis at KO with appropriate strain relief connector (not supplied).
   b. For surface Mounted Conduit (exposed) power supply –
   Provide appropriate conduit to entry location accordingly to local code and attach securely to chassis with correct strain relief connector (not supplied).

5. Drill four(4) holes at locations A, B, C, and D of 5/16″ Diameter(Φ8) x 35MM[1-3/8″] deep if using wall anchors supplied with the unit. Install supplied anchors flush with the wall face, or install another fastening system suitable for wall conditions (not supplied). Attach dryer to the wall. For wood wall/studs use  Dia. M6[1/4″] screws at length that will ensure 25MM [1″] min. stud penetration. For masonry walls use expansion bolts or anchors for Dia.M6[1/4″] screws to ensure penetration 6MM[1/4″] deeper than an anchor. Shim if necessary to ensure the base plate is flat against the wall.

6. Connect supply and ground wires to the terminal block where indicated or connect supply wires to the terminal block where indicated and connect the ground wire to the base plate with a ground screw.
   Connections:
   A. Connect the live wire(colored Brown, Red, or Black) to the terminal block marked “L”.
   B. Connect the neutral wire(colored Black, Blue, White, or Grey) or connect the second live wire(colored Red or Orange) to the terminal block marked “N”.
   C. Connect the ground wire to the terminal block marked “  ” or to the green screw marked “     ”Bare grounding (earth) wires should be sleeved with green and yellow or green tubing.
   The colors of live and neutral wires depend on the voltage of supply service and the requirements of the Building and Electrical Code having jurisdiction.

7. Replace cover. Do not over-tighten screws.

This guarantee will be honored provided that the dryer is installed and maintained in accordance with the instructions. Parts damaged during the installation are the purchaser’s responsibility. The warranty covers defects exclusively, and only liability for the replacement of defective parts will be accepted. This warranty does not cover wear and tear, or misuse and abuse.
Defective parts must be returned, accompanied by the serial number, to the point of purchase. This warranty is granted solely to the original purchaser of the unit and is subject to registration.

MAINTENANCE

Periodic cleaning of the unit is recommended. Remove cover and clean dryer dust lint.

Cleaning stainless steel
Stainless steel is highly resistant to rust, but there are some very strict cleaning and maintenance rules to be followed to prevent damage to its appearance.

General Cleaning Tips
Apply neutral detergents formulated for these purposes (non-ionic surfactants and citric acid). Apply the detergent with a soft cloth. Be careful with abrasive clothes. They may scratch the surface. Rinse with water until all the detergent has gone.
Residue from hygiene products, liquid soap, shampoos, bath gel, etc, can also damage surfaces.
Rinse the surface with plenty of water after use.
Limescale stains can be prevented by drying the surface with a soft cloth after use.

Limescale from mains water: Apply a solution of one part vinegar and three parts water directly to the stains and leave to work for a few minutes. Then rub with a soft cloth or damp sponge. Then give it a final wash with plenty of water and neutral soap to ensure it is thoroughly rinsed.
Unacceptable practices (loss of guarantee)

• Do not apply detergents with abrasive products or which contain:
  Hydrochloric acid
  Sodium hypochlorite (bleach)
  Formic acid.

• Do not use abrasive utensils like metal sourcing pads or abrasive sponges.

• Do not spray the detergent on the surface, because the liquid can get into the openings or crack in them and cause damage.

• Do not use anti-limescale and descaling cleaning products. They are not suitable for cleanings stainless steel.

• Do not use silver cleaners, which contain chlorides that attack stainless steel.

Warning. Important to avoid ( loss of guarantee)
Bleach and descalers are often applied to bathroom equipment and left to work for a time. This leads to the release of gases that contain chloride, which together with the water on the surface cause chlorides to run down the surface of the stainless steel. This rusts both internal and external surfaces.
