discharge point.

ELECTriCAL CONNECTiONS

BEFORE CONNECTING POWER LEADS, SHUT OFF ELECTRICAL
POWER AT FUSE- OR BREAKER-BOX. ALL WIRING MUST
COMPLY WITH LOCAL ELECTRICAL AND BUILDING CODES,
AS WELL AS THE MOST CURRENT NATIONAL ELECTRIC
STANDARDS. CHECK CONTROL UNIT LABEL FOR PROPER
VOLTAGE REQUIRED. DO NOT CONNECT TO VOLTAGE OTHER
THAN THAT SHOWN ON PUMP LABEL.
The EC-1 is designed to be used with an earth-grounding
conductor. To reduce the risk of electrical shock, connect the
earth lead to a properly-grounded circuit. The use of a ground fault
circuit interrupter is recommended.
All wiring should be performed by a qualified installer approved by
local regulations and National Standards. For best performance,
connect the pump to a separate circuit. The control unit/pump
MUST BE CONNECTED TO A CONSTANT POWER SUPPLY,
NOT AN INTERMITTENT SOURCE SUCH AS A FAN OR LIMIT
CONTROL CIRCUIT.
Power Supply:
1. Attach the electrical wires from the pump to the name plate
rated voltage (115V, 208V or 230V) power supply of the air
handler or to a separate power supply.
2. The power leads are color-coded as follows:
a. BLUE = neutral
b. BROWN = live (phase)
c. GREEN/YELLOW = earth (ground)
3. A fuse (purchased separately) should be fitted in the line lead
of the power cable supplying the control unit/pump.
a. 0.50A — 115V 0.20A — 230V
SAFETY SWiTCH CONNECTiONS
The unit is equipped with a high-water or overflow safety switch
with a maximum rated switching current (resistive load) of 8 amps
at 250 VAC or 5 amps at 30 VDC. This circuit is intended to drive
a low power control or alarm circuit and is not sufficient to operate
and switch a large-amperage inductive load.
1. Connect the wires as described below to obtain the desired
response.
2. The safety switch wires are color coded as follows:
a. WHITE or GREY = common
b. RED or ORANGE = normally open
c. BLACK or PURPLE = normally closed
Connecting to Common and NC (Normally Closed) Wires:
When a high-water or overflow condition occurs, the normally
closed circuit opens to turn off the compressor, thus stopping the
flow of condensate water.
1. This is typically done by breaking either the power (R) or
cooling (Y) leg of the low-voltage thermostat.
2. Check with the air conditioner manufacturer to confirm that this
is acceptable for the air conditioner in the application.
3. If acceptable, confirm which thermostat wire is to be interrupted.
4. This connection can also be used with central control systems
to control the air conditioner operation.
5. NOTE: When connected in this manner, if a high water
condition occurs, the air conditioner should not run until the

WARNING
high-water condition is fixed. This method should not be used
if the cooling or heating requirements are a necessity. The
alarm method (normally open circuit) should be used instead.
Connecting to Common and NO (Normally Open) Wires:
When a high-water or overflow condition occurs, the normally open
circuit closes to activate a bell or alarm (not provided, purchased
separately), or to send a signal to a central control system.
1. NOTE: When connected in this manner, if a high water or
overflow condition occurs, the air conditioner is not shut
down and may continue to produce condensation, creating a
potential overflow condition and risk of flooding until the high
water condition is fixed.
TESTiNG THE SAFETY SWiTCH OPErATiON
After the installation is complete and power has been restored to
the air conditioner and control unit/pump, test the operation of the
safety switch to make certain that the installation was done correctly.
1. Turn on the air conditioner.
2. Pour water into the drain tray of the air handler until the pump
energizes. NOTE: Do not continue to pour water if an overflow
condition (flooding) is imminent.
3. Continue to pour water into the drain tray until the high water/
overflow safety switch activates.
4. If the safety switch is wired to the normally closed configuration
described above, the air conditioner should turn off. It should
remain off until the pump lowers the water level in the reservoir
to a middle level associated with alarm-off position.
5. If the safety switch is wired to the normally open configuration
described above, the alarm or bell (purchased separately)
should sound. The alarm or bell should continue to sound until
the pump lowers the water level in the reservoir to a middle
level associated with alarm-off position.
6. When the pump has removed enough of the water to allow
the high-water safety switch to deactivate, the air conditioner
should come on or the alarm or bell should stop sounding,
depending on the configuration used.
SErViCE iNSTrUCTiONS
ENSURE THAT THE UNIT IS DISCONNECTED FROM THE POWER
SOURCE BEFORE ATTEMPTING TO SERVICE OR REMOVE ANY
COMPONENTS.
The reservoir tank should be inspected and cleaned when air
conditioner is serviced and at the beginning of each season. Every
application is different, and the reservoir filter's service interval will
depend upon the amount of debris trapped by the filter screen.
1. To clean the reservoir, carefully remove the reservoir assembly
from its installed position.
2. Depress the latch on the side of reservoir top and tilt upward to
remove, being careful not to damage the reservoir gasket.
3. Remove the mesh screen and rinse thoroughly under
running water.
4. Use a damp towel to remove dust or debris from the reservoir.
5. The float should stay in place on the reservoir top, however if it
has signs of dirt on its surface or it's up and down movement
is impeded, remove it and rinse under water.
6. To remove the float, slide the float retaining clip away and
remove the float from the post. Do not try to disassemble the
float. After servicing the float, re-install float to the post and
