Aspen Universal peristaltic condensate water pump operates with two temperature sensors. These allow the pump to detect and be triggered by a change in air temperature, making this pump suitable for many applications. The Universal is designed to fit in ceiling voids and lift the condensate water from wall mounted machines where a gravity drain is too obtrusive. It can also be used on cassettes fitted with an internal lift pump. The pump can be mounted remotely as it is self-priming to a height of 3 metres and will pump 6.25 litres of water per hour against a maximum head of 12 metres. The pump runs constantly while the air conditioning system is cooling – when the cooling switches off a 3 minute timer ensures that the condensate tray is emptied before the pump switches off. The Universal 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 embarrassing noise. Unlike other pumps using either mechanical or electrical conductivity sensors, the Universal does not suffer from corrosion or contamination problems. - Senses 5C differential across the evaporating coil

115mm(H) x 135mm(W) x 77mm(D) Aspen Universal Peristaltic Pump The Universal Pump peristaltic pump is unique. Integral to the pump are a PCB and two 2 metre
(6.5ft) sensors, which sense 5C differential across
the evaporating coil to operate the pump. This is a
great advantage on systems where anything other
than a 240v cooling signal is used. Simply connect the pump to the condensate tray
(using the vinyl tube supplied). The Universal pump can be mounted remotely as it is self-priming to a
height of 3 metres (9.8ft) and will pump 6.25 litres
(1.65 US gallons) of water per hour against a
maximum head of 12 metres (40ft). The Aspen Universal is designed to run constantly while the air conditioning system is cooling. By placing the red sensor in the ambient ‘air on’ side of the coil and the blue sensor to the ‘air off’ the PCB will sense
5C differential and operate the pump. When the cooling switches off, a 3 minute timer in the pump ensures that the drain tray is emptied before the pump switches off. 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 embarrassing noise. It is not sensitive to water borne contaminants as reciprocating pumps are, and there is no mechanical water sensor to fail! It is also designed to fit in ceiling voids and lift the condensate water from wall mounted machines where a gravity drain is too obtrusive. It can be used on cassettes fitted with an internal lift pump. The rollers act as check valves to stop condensate draining back into the drip tray. The universal pump now has a new push in plug which makes installation and maintenance easier. Aspen Universal Service Guide Inspect pump head regularly and change the pump head tube every 12 months or more frequently if required. If any problems with the pump occur check the
tube first! 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 test switch returns to the NORMAL position automatically after use. ELECTRICAL CONNECTIONS

• Pump rating: 0.2A, 230V AC Alternative voltages available • Maximum water temperature: 40C • Fire retardent plastics Aspen Universal Installation Notes Situate the red sensor in the ambient ‘air on’ evaporating coil (NOT TOUCHING COIL). Position
blue sensor to the ‘air off’ side of evaporating coil. Connect pump to 240v live, neutral and earth. This pump is designed to be sited upright in any position, but at all times it must have free space around the case for ventilation. Ensure that 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. Please note: where space is limited lay and fix
suction vinyl tube along bottom of condense tray,
as pump is self-priming. A variable connector is provided to make easy installation between the condensate tray outlet
and vinyl tube. Product Specification Sheet
