  • Page 7 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. Henden recommends the use of 5L HCl acid, added to 15L of tap water or a ratio of 1 part acid, added to 3 parts of tap water. This should be done in a container suitable of use with HCl acid.

  • Page 11 (represented on the lid with s), and tightened with the locking nut. IMPORTANT: Henden 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, not only as the installation looks more professional, but it also limits potential damage to feeder tubes and probe cables by becoming entangled, or pulled by users during servicing of equipment etc.
  • Page 12 The acid dosing pump is powered by an ELV (extra low voltage) 24VDC supply. On the end of the acid dosing pump power lead is a Tamiya connector (refer Figure 4.13). The Tamiya connector needs to fit into the back of the HWQH controller (refer Figure 4.13). The connector is deliberately designed such that it fits only one way.
