Peristaltic Pump Kit
Commercial Version 2011
Installation Notes – Automatic Dosing System with Peristaltic Pump
To be read in conjunction with the system operating manual
The Heatsavr dosing system is a reliable, accurate and convenient way to
ensure Heatsavr is added to the pool on a regular daily basis. Each dosing
unit is programmable to provide the optimum dose of Heatsavr and at a
scheduled time most suitable for the pool concerned.
If required, dosing units can be pre-programmed before despatch.
For full programming details see operating manual.

---|---
Tools required:| 11/32” Drill bit
⅛ ” BSP Tap
Injection point:| The first thing to establish when installing a system
is the location of the injector. This should be situated in the return pipe of
the pool filtration system, downstream of the filter and heater (if possible)
and at least 200 mm from any other chemical injection points.
BEFORE FITTING THE INJECTOR TURN OFF THE MAIN FILTRATION PUMP AND
ISOLATE PIPEWORK IF POSSIBLE.
Drill the pool return pipe in the chosen location (ideally on a fitting where
there is greater wall thickness).
Carefully tap the drilled hole and then screw in the injector using PTFE tape
to ensure a good seal.
Dosing Unit:| This should be sited away from any other pool chemicals,
away from foot traffic and as close as possible to the Heatsavr injection
point.
Do not locate outdoors or close to open flames or electrical heating elements.
Mount on a firm vertical surface as shown in the operating manual.
Ideally maximum lift from base of Heatsavr reservoir to pump and/or injection
point should not exceed 2 metres. The standard length of delivery tube
supplied with the kit is 3 metres, although additional tube is available for
longer runs. If particularly long runs or higher pump pressures are required
then an alternative diaphragm pump may be more suitable. Please consult
Brenntag UK Limited for advice.
Reservoir:| For domestic and commercial pools with surface areas up to
100 m² the 2 litre containers in which Heatsavr is supplied can also be used
as the reservoir. This should be stood in a plastic bucket or similar to act
as a bund. For pools above 100m² a 25 litre
day tank and bund is normally used.

Suction plumbing:| Without low level alarm – Pass one end of the
clear soft plastic tube supplied through the rubber bung and draw sufficient
tube through so that it will reach the bottom of the tank. Feed the weight
over the end of the tube and attach the strainer end fitting. If not already
fitted fit the air release valve into the other hole in the rubber bung and
fit the bung firmly into the top of the reservoir. Ensure that the valve is
fitted the correct way round to allow air to enter the reservoir. Connect the
other end of the soft clear plastic tube on to the suction side of the pump,
cutting off any surplus to requirements.
With low level alarm – If not already fitted to the day tank, insert
suction probe into the opening on the shoulder of the tank and secure rubber
flange with the screws provided. Probe can be adjusted through flange until
its end touches the bottom of the tank. The rubber “O” rings should be moved
down the shaft of the probe to secure its position. Connect the end of the
soft clear plastic tube from the suction probe on to the suction side of the
pump, cutting off any surplus to requirements.
Delivery plumbing:| Connect one end of an appropriate length of the
opaque plastic tube to the connector on the delivery side of the pump and the
other end to the connector on the injector cutting off any surplus to
requirements.
Electrical:| The dosing unit is supplied complete with a flying lead,
and should either be fitted with a standard plug incorporating a 3 amp fuse or
connected to a 3 amp fused. Low level alarm option: Pass the flying lead from
the suction device through the spare gland at the base of the pump case and
connect into the right hand green terminal marked LEVEL at the bottom of the
printed circuit board.
Priming:| To ensure an accurate first time dose the pump and tubes
require priming in order to purge out the air. This can be achieved by holding
down the up (+) button for 3 seconds to start the pump manually. Press again
to stop when all the air in the tube has been expelled and the system is
primed.
Programming:| Each pump requires programming to suit the pool concerned.
Please refer to the Heatsavr Dosing Unit Programming Sheet for setting up the
clock and adjusting the dosage rate and time.
Liquid Storage:| Store in original container below 40ºC and above 5º C
in a separate place to other stored chemicals. Keep container tightly closed.
Storage area should be under cover away from direct sunlight. Store away from
sources of heat or ignition.
Health and Safety:| Ensure that appropriate Health and Safety signs are
displayed adjacent to the Heatsavr pump reservoir and the Heatsavr storage
area.
Ensure that all operators have copies of and read the Material Safety Data
Sheet and Heatsavr Standard Operating and Handling Procedures
Maintenance:| Dosing set tube should be replaced annually – see below.
Check time and dosing rates periodically to ensure correct operation.
IMPORTANT – PERISTALTIC TUBE REPLACEMENT.
It is recommended that the dosing pump metering tube (peristaltic tube) is
replaced at least once a year to ensure that correct dosing is maintained.
Below is a typical dosing pump schematic. Appearance of the pump may vary a
little but in all cases the peristaltic tube is located by unclipping the see
through plastic cover at the front of the pump compartment. First undo the
unions and disconnect the main suction and delivery tubes. Release the left
hand union fitting by sliding it out of its holder. By rotating the wheel
assembly manually clockwise the peristaltic tube can be eased out from within
the wheels. Remove completely by sliding out the right hand union.
Fit the new peristaltic tube by first securing the left hand union and feed in
tube whilst rotating the pump wheel assembly manually clockwise. Secure right
hand union and reconnect the suction and delivery tubes.
