Note: The "compressor or cooling signal" neutral phase (common) needs
to be the same neutral phase (common) that is used to supply power to the
controller.
PCT Series (temperature signal) FOR PROPER PUMP OPERATION, PLEASE
FOLLOW THESE INSTRUCTIONS:
(line) and the blue wire to the neutral phase (common) (See Figure 2). Make
sure power is off when connecting the temperature sensor to the pump.
Connect the sensor cable to the pump by connecting the 4 prong plug to the
corresponding cable on the pump. There are 2 lead wires with sensors at the
ends, one lead has a blue end and the other has a a red end. Affix the lead with
the blue sensor to the "cold" or "air out" side of the evaporator coil and the red
sensor to the "hot" or "air in" side of the evaporator coil. (See Figure 2)
The pump will start when a temperature difference of 5°C (9°F) is reached
between the blue and red sensor. As long as the difference in temperature is
more than 5°C (9°F), the pump will operate. When the difference in temperature
is less than 5°C (9°F), the current cuts off and the pump will continue to operate
for 5 minutes then stop. NOTE: Never put the sensors directly into water or
condensate. Do not attach the sensors to the refrigeration piping. Do not leave
the sensors loose in the open air.
PCR Series (reservoir control tank) - Connect the brown wire to the main phase
(line) and the blue wire to the neutral phase (common) (See Figure 4). Make
sure power is off when connecting the reservoir to the pump. Connect the cable
from the reservoir tank to the pump by connecting the 4 prong plug to the
corresponding c
able on the pump.
PCR-10S Series (overflow/alarm connection) - Connect the cables as
described below to obtain the desired response:
C and NC – When water rises, circuit opens to turn off the compressor and
prevents overflow by connecting the gray with the blue stripe wire and the
yellow with the blue stripe wire. (See Figure 5)
C and NO – When water rises, circuit closes to activate a bell or alarm (not
provided) by connecting the gray with the blue stripe wire and the purple with
the yellow stripe wire. (See Figure 5)
The rating for the alarm circuit is 200VDC, 1 Amp max., and 15 Watts max.
Pump to Power Supply:
Brown – main phase (line)
Blue – neutral phase (common)
After electrical connections have been made, check the pump for proper
operation. Press the test switch to determine if pump operates properly.
Connect the brown wire to the main phase
SERVICE INSTRUCTIONS
MAKE CERTAIN 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 whenever air
conditioner is serviced or at the beginning of the season.
Reservoir: Carefully remove the reservoir cover by gently flexing the locking
tab. Be careful not to damage the o-ring. Remove the mesh screen and rinse
under running water. Remove any debris that may block the mesh. Use a
damp cloth to remove dust or debris from the reservoir. When re-installing the
float/magnet, be certain that the beveled edge of the float is up and the magnet
is properly seated before reassembling the reservoir. Carefully hook the cover
and then press it onto the tank until the spring tab snaps in place. Use care to
make sure the o-ring is properly installed (that is not twisted, torn or otherwise
out of its
track.)
REPLACEMENT PARTS
Pump Tubing Replacement:
1.
Disconnect pump from power source.
2.
Open transparent cover.
3.
To remove the pump tube, put the rotor in a vertical position and remove the
inlet side tubing from its left seat. Pull tubing upwards while rotating the rotor
manually clockwise. Fully remove the tube from the right seat.
4.
Before installing the new tube, apply a small amount of silicone grease on
the tube. This will help lubricate the tube. No other lubrication is required.
5.
To install the pump tube put the rotor in a horizontal position. Push inlet side
tube connector into left seat and make sure it is fully inserted. While rotating
the rotor clockwise, push the tubing in place. Once the tubing is moved into
position then insert the outlet connector into the seat of the right side.
6.
Close transparent front cover.
Disposal of Product:
Dispose of or recycle product properly, according to all relevant authorities.
