1.1 Proper use of the Pump
The Henden pH Dosing Pump should be used only for the
purpose for which it has been expressly designed namely
the dosing of liquids. Any different use is to be considered
dangerous. The pump should not therefore be used for
applications that were not allowed for in its design. In
case of doubt, please refer to the details listed within this
document, or contact your point of purchase or Henden for
further information. Henden will not be liable for damage
deriving from improper, erroneous or unreasonable use of
the Henden pH Dosing Pump.
1.2 Risks
•
After unpacking the pump, make sure that it is
completely sound. In case of doubt, do not use the
Henden pH Dosing Pump and contact Henden.
•
The packing materials (plastic bags, polystyrene, etc.)
should be kept out of the reach of children: As they may
constitute a potential source of danger.
•
Before you connect the Henden pH Dosing Pump make
sure that the voltage ratings correspond to your particular
voltage supply. You will find this value on the rating plates
attached to the Henden pH Dosing Pump.
•
The electrical installation to which the Henden pH Dosing
Pump is connected must comply with the local standards
enforced in the state or country under consideration.
•
Use of electrical equipment always implies observance of
some basic rules. In particular:
– Do not touch with wet or damp hands or feet
– Do not operate the Henden pH Dosing Pump with bare
feet (example: swimming pool equipment)
– Do not leave the equipment exposed to atmospherit agents
– Do not allow the Henden pH Dosing Pump to be used by
children or unskilled individuals without supervision
Never connect your pH pump direct to
mains power. Always connect it to the
chlorinator power supply so it operates
during the preset filtration time cycles.
•
In case of breakdown or improper functioning of the
pump, switch it off, but do not touch. Contact Henden
for technical assistance for any necessary repairs and
insist on the use of original spares. Failure to respect
this condition could render the Henden pH Dosing Pump
unsafe to use.
•
When the Henden pH Dosing Pump is not in use for a
substantial period of time, or use is to be discontinued,
disconnect the unit from any power supply.
Before carrying out any service on the Henden pH
Dosing Pump:
1 Disconnect the mains power from the unit and
2 Relieve all the pressure from the pump head or the
injection tube
In the event of possible losses on the hydraulic system of
the pump (breakage of the o-ring, the valves or the hoses),
stop the pump immediately and contact Henden.
1.3 Toxic and/or Dangerous Liquid Dosage
To avoid risk from contact with hazardous liquids or toxic
fumes, always adhere to the notes in this instruction
manual and wear protective clothing (gloves, goggles &
overalls). You must:
•
Follow the instructions of the dosing liquid manufacturer.
•
Check the tubing regularly and use only if there is
no damage.
•
Contact Henden for technical assistance for any
necessary repairs and insist on the use of original spares.
•
Before disconnecting the metering pump, make sure to
flush out and neutralise the pump head with water.
1.4 Instructions for diluting pool acid
The Henden pH pump automatically doses a diluted acid
solution into the pool when the pH level needs to be
reduced. The peristaltic pump draws this diluted acid from
a container in which the solution is mixed.
Use the table provided to determine what water/acid ratio
is recommended for your pool, in an approved 20 litre
Hydrochloric Acid container.
IMPORTANT:
KEEP BARE HANDS AWAY FROM POOL
ACID AND ALWAYS USE CAUTION WHEN
HANDLING POOL CHEMICALS.
