J.W. HARRIS brazing alloys are
the cleanest and brightest alloys
made. Free of oxide and surface impurities,
the purity of Harris alloys runs
all the way through the rod. Purity
makes a huge difference in the integrity
of a brazed joint. Leaks are caused
by oxide and impurities.....
Standard Peristaltic
Pump no sensor required Simply connect the Aspen Standard Pump
to the approprate drip tray (ising the vinyl tube supplied),
mains supply and control link to the air-conditioning units
cooling signal. The pump can be mounted remotely as it is self-priming
to a height of 2 metres and will pump 6.25 litres of water per
hour against a head of 12 metres.
The Aspen Standard pump is designed to run
constantly while the air conditioning system is cooling.
This is achieved by linking the pump to the
cooling signal. When the cooling switches off, a timer in the
pump ensures that the drain tray is emptied before the pump
switches off. The signal wire can be connect to the cooling
signal and therefore on heating, the pump does not run.
The pump is a peristaltic rotary
type - which means that it is quiet in operation, very reliable
and will run dry without fear of damage or any embarassing noise.
It is not sensitive to water borne contaminants as reciprocating
pumps are, and there is no mechanical water sensor to fail!
It is designed to fit in ceiling voids and
lift the condensate water from wall mounted machines where a
gravity drain is too obstrusive. It can be used on cassettes
fitted with an internal life pump. The rollers act as check
valves to stop condensate draining back into the drip tray.
The standard pump now has a new push
in plug which makes installation and maintenance easier.

SERVICE
GUIDE
Inspect pump head refularly and change the pump head tube
every 12 months or more frequently if required.
To remove pump head make sure the roller
assembly is vertical. Remove transparent cover and fit
replacement pipe. The addition of a smear of silicon grease
will ease the refitting of the lid, reducing potential
friction noise.
This only takes 3 minutes!
The last switch should always be returned
to the NORMAL position after inspection

INSTALLATION
NOTES
This pump is designed
to be sitted upright in any position, but at all times
it must have free space around the case for ventilation.
Ensure there are no kinks or trapped sections in the piping.
Vinyl piping must have an ID 1/4" by OD 3/8".
Fix the pipes with the tie wraps to the pump outlet and
inlet.
A variable connector is provided to make easy installation
between the conensate tray outlet and vinyl tube.
