4.2.2. General information about the acid dosing pump

ATTENTION: If any of the instructions here contained is not respected, there can be
damage to persons &/or incorrect working, or damage to the apparatus.
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.

4.2.3. 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.

4.2.3.1. 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 sides on the bracket.

4.2.3.2. Suction filter installation:

• Insert the end of the tubing in the weight so that it exits from the
flared part (refer Figure 4.2);
• Insert the filter container in the same end of the tubing (refer
Figure 4.2);
• Tighten the tubing screwing the weight until it sits on the bottom
of the acid drum;
• It is strongly recommended to use the suction filter in all
situations; and
• Clean it periodically to avoid dry residual of product,
accumulation of dirt.
