SAFETY WARNING
Risk of electric shock. Make certain that the power supply to the unit/system
is disconnected before attempting to install, service, or remove any
component.
The pump unit must not be immersed in water, installed outside the premises,
stored in a damp environment, or exposed to frost. This pump has not been
tested for use in swimming pools or marine areas. To reduce the risk of
electric shock, read the instruction manual for proper installation and
install the pump and all electrical components above the top grade level of
the sump.
CAUTION: This pump has been designed for use with water only. All
condensate collection elements (collection tray, connecting tubes, outlets
etc…) must be cleaned thoroughly prior to installing the pump.
The pump is supplied with:
– A self-resetting thermal cut-out set at 115°C (239°F).
– A self-extinguishing body case (UL94 VO Material)
When installed outside the AC unit, the pump must not be accessible without
the aid of a tool.
Pump Power Supply
Connect pump Phase and Neutral terminals to the air conditioner unit’s power
supply or to the mains supply by means of wiring to comply with local National
Standards. We suggest the use of :
– An interconnecting power cable (CE: HO5 VVF 2 x 0.5 mm2; UL/CSA: 2 x 0.5mm²
(AWG20) certified UL2464 – 80°C – 300V) must be fastened securely to the wall,
to avoid inadvertent disconnection during installation and later servicing.
– This connection should be equipped with an electrical isolation device (2A
Fused Spur, customer provided) to the Phase and Neutral.
The pump must be powered by an electrical circuit protected against
overvoltage> 2.5kV.
Pump safety switch
IMPORTANT: Connecting the cable of the safety switch is indispensable to
avoid any risk of overflowing. For correct connection, refer to the appliance
instructions. The pump is equipped with an NC high water safety switch with a
maximum rating of 8A/250V (safety switch CE: 2 x 0.5mm2, UL/CSA: 2 x 0.5mm2
(AWG20)).
This contact may be used to switch off the air conditioner where there is a
risk of condensate overflow (after thorough verification by the installer of
the customer’s specific application and the resultant electric wiring
diagram).
Initial operational test
– First clean the condensate tray of any debris left over from the manufacture
or unpacking of the air handling unit.
– Pour water into the condensate collection tray (a squeezable plastic bottle,
ACC00401, is available).
– Check that the pump unit starts & then stops as the water level decreases.
– Check the safety switch by continuing to pour water until the alarm triggers
(cutting off the compressor).
The detection unit requires maintenance and must be cleaned at regular
intervals in accordance with the degree of pollution existing within the
operating environment.
If the pump doesn’t start, check the wiring and incoming power supply.
For all problems first check:
– the discharge lines are neither obstructed nor kinked,
– the float inside the detection unit is not blocked
– the hydraulic inlets nor outlets are not obstructed
If the pump is running continuously ( >1min), check:
– the discharge height is < 10 m (33 ft)
– the pump is suitable for the capacity of the air conditioning unit,
– while starting the pump, the flow of the water poured into the collection
tray was not too high (ex:1l en 30s=60l/h >>20l/h – 1/8 gal in 30s = 15gph >>
5gph)
If the pump is running continuously and there is no suction of» water,
– check that the suction hose (the hose that connects the pump and detection
unit) is connected and air-tight.
If the pump cycles continually or does not shut off,
– check the detection unit is mounted level.
– turn the pump off and see if the water returns down the discharge line. If
water returns down the line you should replace the pump.
