Typical Variable Speed Applications:
- Zone Valves
- Panel Radiation with Thermostatic Valves
- Radiant Loops with Actuators
– Varies speed to maintain proportional or constant pressure differential (AP, Δ(8P)
- Location: The circulator can be installed on the supply or return side of the boiler but for best system performance, it should always pump away from the expansion tank. See piping diagrams in Figure 2 and Figure 3.
- Mounting position: Circulator must be mounted with the motor in the horizontal position. See diagrams below for acceptable motor mounting orientations.
CAUTION: Do not use flat rubber gaskets. Only use O-ring gaskets provided or leaks may result. Warranty will be void.
ACCEPTABLE MOTOR MOUNTING POSITIONS
Always install with motor in horizontal orientation. Position electrical junction box at 9 o’clock for best viewing orientation. Pump casing may be rotated to change flow direction. Locate the arrow on the casing body to determine flow direction. To rotate the pump casing, remove the 4 motor screws. motor housing from the casing. Damage to the casing proper flow direction desired as shown in Figure 4 and Figure Be sure motor is positioned correctly and is seated evenly screws evenly to 25-38 in-Ibs torque.
CASING ROTATION
When rotating pump casing position, DO NOT detach O-ring and leakage may
result. Simply spin casing to theFigure 5. Reattach the 4 screws (%” allens
wrench required). evenly to prevent leakage or damage to O-ring. Tighten
motorIntegral Flow Check (IFC®) option – An IFC® is included in the carton. If
required, press IFC into machined discharge port with plunger and o-ring
facing in, until it snaps into place. Before installing, press IFC plunger to
be sure it moves freely. See diagram above.
CAUTION: To reduce the possibility of noise transmission, be sure to add
vibration dampeners to piping when mounting circulator to wall or floor
joists.
-
Filling the system: Fill the system with tap water or a maximum of 50% propylene-glycol and water solution. The system must be filled before operating the circulator. The bearings are water lubricated and should not be allowed to operate dry. Filling the system will result in immediate lubrication of the bearings. It is always good practice to flush a new system of foreign matter before startin the circulator.
WARNING: Risk of electric shock. To reduce the risk of electric shock, be certain that it is connected only to a properly grounded, grounding-type receptacle. Follow all local electrical and plumbing codes.
WARNING: Use supply wires suitable for 90°C.
WARNING: Disconnect power when servicing. ‘
CAUTION: Use flexible conduit only. Not for use with rigid conduit.
WARNING: SERVICING OF DOUBLE-INSULATED APPLIANCES. A double-insulated appliance is marked with one or more of the following: The words “DOUBLE INSULATION” or “DOUBLE INSULATED” or the double insulation symbol (square within a square). In a double-in- sulated appliance, two systems of insulation are provided instead of grounding. No grounding means is provided on a double- insulated appliance, nor should a means for grounding be added. Ser g a double-insulated appliance requires extreme care and knowledge of the system, and should be done by qualified service personnel. Replacement parts for a double-insulated appliance must be identical to the parts they replace. -
Wiring the circulator: Disconnect AC power supply. Remove terminal box cover. Attach a wiring connector into knockout hole.
Use flexible con-duit only. Connect Line/Hot power to the black lead, Neutral to the white lead. See wiring diagram.
Note:
If pigtail leads provided are not used, be sure to trim field wire to a strip length of .25″ (+/- .025″) to prevent exposed wire causing a short at the terminal plug. Connect line and neutral to green terminal plug as shown in diagram. Depress the spring tab with a small screwdriver to insert wire into plug. Release tabs to complete connection. The 0018e is a double insulated circulator, no grounding wire is necessary. Replace terminal box cover.
-
Start the circulator: When purging the system, it is recommended to run the circulator at manual full speed operation long enough to remove remaining air from the bearing chamber. To do this, turn the dial clockwise to the ZONE CIRC – MAX position. This is especially important when installing the circulator in the off-season.
Full Speed Operation:
To run the pump at full speed during the fast fill, start-up and purge process, rotate dial clockwise to MAX speed setting. To return to the normal operating mode, turn dial to desired fixed speed, constant pressure, or proportional pressure setting.
CAUTION: Never run the circulator dry or permanent damage may result. -

b. Manual Dial
Note: The 0018e is factory-programmed for maximum speed operating mode. A
Blue LED will appear when first powered on.
If this is your desired operating mode, no programming changes are required.
The 0018e has 3 Operating Modes on the Selector Dial:
- Proportional Pressure ( TRV ) – Varies speed to maintain a proportional/variable pressure differential.
- Constant Pressure ( ZV ) – Varies speed to maintain a constant pressure differential.
- Fixed Speed ( ZONE CIRC ) – Infinitely adjustable settings (MIN-MAX).
0018e® PERFORMANCE CURVES
In TRV – Panel Radiator, Proportional pressure mode, the circulator maintains a proportional pressure differential (Ap-v) as heating load increases or decreases. Flow will change in relationship to the change in pres- sure differential. Selection options are Medium or High. If unsure on proper setting, select Medium and adjust as needed.
In Zone Valve – Constant pressure mode, the circulator maintains a constant pressure differential (Ap- c) in the system as heating load increases or decreases. Selection options are Medium or High. See chart to left for equivalent 00 model at each setting.
ZONE CIRC – Fixed speed mode allows the installer to fine tune the circulator
flow rate to precisely match design load conditions. It is infinitely variable
between MIN/MAX settings. See chart to left for equivalent 00 model at each
variable speed setting.
CAUTION: Do not attempt to remove LED panel from circulator. Serious
damage to circulator electronics may result.
7. Troubleshooting the error codes: Listed below are potential
diagnostic error codes which will appear on the LED display in case of a
malfunction.
CONTROL
FAULTS
PANEL
| CAUSES| REMEDIES
---|---|---
The circulator is noisy| LED on| Suction pressure is insufficient –
cavitation| Increase the system suction pressure within the
permissible range.
LED on| Presence of foreign bodies in the impeller| Disassemble the motor and
clean the impeller.
Loud noises of water circulation| Flashing white LED| Air in the system| Vent
the system. Repeat fill and purge steps.
LED on| The flow is too high| Reduce the pump speed.
Circulator is not running although the electrical
power supply is switched on
| LED off| Lack of power supply| Verify voltage value of the
electric plant.
Verify the connection of the motor.
One fuse in the installation i s blown| Verify the fuses of the pump.
The circulator is defective| Replace the pump.
Overheating| Let the pump cool down for some minutes. Then try to re-start it.
Verify that the water and ambient temperature are within the indicated
temperature ranges.
LED red| The rotor is blocked| Disassemble the motor and clean the impeller.
See unblocking procedure below.
| | Insufficient supply voltage| Verify that the power supply matches the data
on the name plate.
Building does not get warm.| LED on| The circulator performance is too
low| Increase the suction head. Increase speed or Δ P setting.
Unblocking Procedure:
A red light in the LED indicates the circulator rotor is blocked or sticking.
Turn the selector to the position MAX, disconnect and connect power supply to
start the automatic release process. The circulator makes 100 attempts to
restart (process lasts approximately 15 minutes). Every restart is signalled
by a short flash of white LED light. If the blocking is not removed through
the automatic release process after 100 attempts to restart, the circulator
goes into standby and the LED remains solid red.
Perform the manual unblocking steps described below.
- Disconnect power supply – the warning light switches off.
- Close both isolating valves and allow cooling. If there are no shut-off devices, drain the system so that the fluid level is beneath that of the circulator.
- Loosen 4 motor bolts. Remove motor from casing. Carefully pull the rotor/impeller from the motor.
- Remove impurities and deposits from the impeller and casing.
- Reinsert the rotor/impeller into the motor.
- Set the dial to the MAX position.
- Connect power supply. Check for impeller rotation.
- If the circulator still doesn’t run it will need to be replaced.
