4.3.2. General information about the acid dosing pump

ATTENTION: If any of the instructions here contained are not respected, there can
be damage to persons &/or incorrect working, or damage to the apparatus. Davey
recommends the use of "Pool grade" 15% concentration Sulphuric Acid. Suitable
Personal Protective Equipment (PPE) should be worn during the process. Consult
warnings on chemical containers where necessary.
ATTENTION: The acid drum should be located at least 2 meters from any other pool
equipment. If the acid drum is located inside a room or an area with limited ventilation
then a vent hole needs to be drilled in the lid and tubing run out to open area.
Acid fumes will damage equipment and will not be covered by warranty.
The acid dosing pump needs to be installed a minimum of 2m away from the chemical drum, but no
higher than 1.5m above it. When installing the pump, read the labels and verify the following:
• Tubing material is compatible with the liquid;
• The pressure at the injection point is lower, or equal to the pump nominal pressure;
• Acid (suction) feeder tubing is inserted in the liquid container, fitted to the suction connection of the
pump (represented on the lid with r) and tightened with the proper nut;
• Acid (delivery) feeder tubing is fitted to the delivery connection of the pump (represented on the lid
with s), tightened with the proper nut;
• Allow sufficient length of feeder tubing to reach the proposed probe & acid dosing injection housing;
and
• The locating lugs for the clear cover of acid dosing pump are correctly seated.
IMPORTANT: Davey recommends ensuring that all feeder tubing and probe cables
be attached to pipework where possible. Use "cable ties" or "sticky/electrical tape".
This is good practice as it not only looks more professional, but also limits potential
damage to feeder tubes and probe cables by becoming entangled, or pulled by users
during servicing of equipment etc.

4.3.3. Mounting the acid dosing pump

ATTENTION:
Before carrying out any operation on the pump, disconnect the power supply.
The acid dosing pump needs to be installed a minimum of 2m away from the acid chemical drum (not
included), but no higher than 1.5m above it.
4.3.3.1. Installation with the provided bracket:
• Fix the metal bracket with the provided screw;
• In case of tiled, or low friction walls, use the supplied adhesive tape as follows:
- Peel off one of the two protective foils from the tape;
- Stick the tape to the bracket;
- Peel off the second protective foil; and
- proceed to fix the bracket with the provided screw.
• Fix the pump on the bracket ensuring tongues on the back of the pump slides onto the bracket.
