INSTALLATION
1. Carefully unpack the unit, check for damage and make sure t hat all of the required parts are included. The
units are thoroughly tested before packaging to ensure saf e delivery and operation. If there is any sign of
damage due to shipment, return it to the place of purchase for repair or replacement.
2. Choose a mounting location near the air-conditioner. The pump must be mounted level and the inlet must
be below the lowest drain.
CONNECTING THE PIPING
1. Run flexible tubing or pipe from the a/c condensate drain to the inlet hole on the pump. This drain line
should have a continuous downward slope to allow gravity flow. Cut the end of the line at an angle so
the end does not close off on the bottom of the pump’s tank.
2. Connect the discharge line by hand. A flexible tubing with an internal diameter of 3/8” will be suitable.
Extend the discharge line straight up from the pump to the highest point, run the discharge line to a drain
with a downward slope.

CONNECTING THE PIPING
For best results, the drain should be below or approx. level with the bottom of the pump tank. If it is not
possible to slope the line downward, make an inverted “U” trap at the highest point of the discharge line
above the pump.
For further installation advice please call the technical support helpline on +44(0)115 900 5858.
WIRING
Shut off electrical power at the fuse box before making any wiring connections. All wiring must be done
according to local and/or applicable national codes.
1. Main power: Connect the power cord to a constant line voltage source, not a fan or other device that
may run intermittently.
2. Overflow alarm switch: The pump is equipped with an overflow alarm switch (NC) that switches off the
air conditioner in the event of pump failure. Max power rating is limited to 3VA. In cases where cooling
requirements are a necessity, the alarm switch may trigger an optional or acoustic signal emitter.
3. If fused plug is used, a 3 amp fuse is recommended.
TESTING
1. With the unit plugged in and the discharge line in place, pour water into the pump reservoir until the unit
activates to verify the unit works properly.
2. To test the overflow alarm circuit :
• Energise the appliance so it runs.
• Kink the tube coming from the pump discharge, or unplug the power cord, so it cannot pump out.
• Pour water into the pump reservoir, filling it completely
• As the water level nears the top of the unit the overflow alarm should activate (e.g. triggering an
alarm circuit, if used).
• Un-kink the tube, or plug the cord in, and allow the pump to empty the tank. As the water level
goes down the overflow safety switch will deactivate and the appliance will energise again (or the
alarm will reset)
MAINTENANCE
1. Before attempting to service or remove any component, make sure that the unit is disconnected from the
power source, including the overflow switch
2. Unfasten the check valve with a spanner. Clean the check valve and verify it is operation.
3. Disassemble the cover and water tank from the main plate.
4. Be sure the floats move freely. Clean as necessary.
5. Clean the tank with warm water and mild soap.
6. Check the inlet and outlet piping. Clean as necessary. Be sure there are no kinks in the line that would
inhibit flow.
7. After the servicing, assemble the unit by the reverse order.
8. To re-install the check valve, fasten it manually and tight en with a wrench.
9. In case of a long-term break, remove water from the hose an d the water tank.

TROUBLESHOOTING
3. Unit runs but does not pump liquid out:
• Check the floats to be sure that they are not stuck in the up position.
• Check the height of the discharge tubing to be sure it does not exceed the allowed head
(see specifications)
• Check the discharge tube for obstructions and clear if needed.
• Check the check valve for obstructions. Refer to the maintenance section for cleaning instructions.
4. Liquid drains back into pump from discharge line:
• Check valve may have debris in it. Refer to the maintenance section for cleaning instructions.
• If the discharge line is plumbed so the highest point is less than 1m above the pump, the check
valve may allow liquid to drain out of the line. This is normal and will not damage the pump.
5. Liquid leaks from around the check valve
• If the check valve is too tight or too loose it may leak around the O-ring.
• If the O-ring under the check valve is damaged, replace with a new one or purchase a replacement
check valve, which includes an O-ring.
For further installation advice please call the technical support helpline on +44(0)115 900 5858.
If the pump does not function properly, refer to the following:
1. Unit does not run:
• Check the power supply.
• Check the appliance to see if condensation is actually being generated.
• Check to make sure the pump float mechanism moves freely and clicks the activation switch when
moved up and down.
• Check the drain line(s) into the pump for obstructions. Note: If these lines are clogged and remain
clogged, the appliance may eventually be damaged.
2. Pump makes loud noise when running:
• Check the tank for debris and clean if necessary. Refer to the maintenance section for cleaning
instructions.
