PRODUCT SAFETY

Operation of this pump is via the internal float which activates a micro
switch. It also includes a Hi Level Safety Switch (operated by a second
internal float) which can be used to stop the air conditioning system in
the unlikely event of pump failure.
IMPORTANT: This pump has been designed for the removal of PH
neutral condensate water only. It should not be used in swimming
pools, marine environments, or environments that are particularly dusty
or oily.
This pump must not be run dry and it is not submersible.
WARNING: This appliance is not intended for use by persons (including
children) with reduced physical, sensory or mental capabilities, or lack
of experience and knowledge, unless they have been given supervision
or instruction concerning use of the appliance by a person responsible
for their safety. Children should be supervised to ensure that they do
not play with the appliance.

The pump is designed to sit level on its ba se or to be fi xed to a vertical surface. A
spirit level is built in to the pump’s casing to aid levelling the pump. x2 screw
holes are provided in the back plate of the pump for fixture to a vertical
surface.
This pump is des igned for installation indoor s only. Do not position this pump where it
is likely to be subject to water ingress.
The discha rge pipe can be 6mm or 10mm ID. It should be secured to the out let barb
using the cable ties provided. It is important to ensure that there are no kinks or
restrictions in the discharge pipe.
Three openings are provided for inle
t of condensate water at the fron t of the pump,
two on the rig ht hand side and one on the left. The inlet pipe/s must be fitted so
that it/they push/es fully into one of the openings and cannot come loose.

The pump must be earthed. It is suitable
for connection to a 230v 50hz AC
power supply using the Supply Cable
provided. Connection to the electrical
supply must be via a double pole isolation
switch having a separation of at least
3mm in each pole (Brown = Live,
Blue = Neutral, Green/Yellow = Earth).
The two black wires are for connection of the
internal hi-Level safety switch. The switch
has a maximum rating of 3 amps and can
be used to stop the air conditioning
system in the unlikely event of pump
failure and should always be utilised.
This pump must be installed and
commissioned by a competent person in
accordance with these instructions.
Following installation and commissioning,
the operation of this pump should be
explained to the user and these instructions
left with them for future reference.

The following diagrams indicate three methods in which the hi level safety switch can
be used to interrupt the live connection between the fan coil and the condenser.
Electric al installation must be carried out by a competent person and be in accordance
with local wiring regulations. Ensure the electrical supply is switched off before
making any connections to the pump.
Following installation of the pump the reservoir should be filled with water
until the motor runs. Pipes and connections should be checked for leaks
and discharge of water checked; The operation of the safety switch
should also be checked.

A. Live connection is < 3 amps
B. Via a suitable contactor relay (normally open) where
the live connection is above 3 amps
C . Where interruption of the live or neutral connections
lead to comms problems

The pump reservoir can be removed with ease for
cleaning purposes by undoing the screw located at
the front of the pump, depressing the front and
allowing the reservoir to be moved downwards (care
should be taken as there may be water in the reservoir).
Not e: T he pump does not need to be removed from its
fixings to clean the reservoir. The quick release outlet
barb can be removed very easily by twisting and
pulling out.
The pump should be flushed through with anti-
bacterial wash every 6 months to avoid sludge build
up in the pump reservoir. Note: Contractors should
satis fy themselves that any chemicals used are
suitable and will not damage the pump.
If the supply cord is damaged the pump must be
switched off until the supply cord is replaced by a
suitably qualified person to avoid a hazard.
Note: Servicing and maintenance should be carried
out by a competent person.

Fault conditions:
In the unlikely event of a pump failure check the following:
Power Supply – Ensure power is supplied to pump.
Hi Level Safety Switch – Ensure hi level safety switch has not operated. If it has, check
pump performance is suited to incoming flow rate.
Inlet Pip e – Check pipe is not blocked with debris or kinked.
Outlet Pipe – Check pipe and outlet barb are not blocked with debris or kinked.
Reservoir – Check reservoir is not blocked with debris.
Note: Fault conditions should be checked by a competent person.
If these checks do not resolve the problem please contact Airflow Developments for further
assistance.
