2.3.1 Additional materials
The following are required for the installation of the
controller and must be supplied by the installer:
1. A cable to connect the pump to the remotely mounted
controller, minimum size of 22 AWG (Jandy part number
4278). This cable will need to have four (4) conductors
and be able to handle 24V control signals. This cable
should be rated for the particular installation (for
example: outdoor, UV resistant, direct burial, etc.) and
should conform to all applicable codes and regulations.
(A suitable cable is included in the Jandy Pro Series
variable-speed pumps.)
2. A minimum of two (2) fasteners to mount the controller
back plate to a wall or electrical box. The fasteners
should be suitable for the surface where the controller is
to be remotely mounted.
3. A high-voltage
disconnect switch, as required by the
National Electric Code
®
(NEC
®
), within line of sight of
the pump.
2.4 Installation of the Backplate onto an
Electrical Box
CAUTION
Do not expose the user interface to direct
sunlight. Too much direct sunlight will darken
the LCD screen, and it will no longer be
readable.
1. Turn off the pump at the control panel.
2. Turn off all electrical power to the pump at the main
junction box or at the circuit breaker providing electrical
power to the pump.
WARNING
ELECTRICAL SHOCK HAZARD
Turn off all switches and the main breaker in
the ePump electrical circuit before starting the
procedure. Failure to comply may cause a shock
hazard resulting in severe personal injury or death.
3. Drill out the plastic covering the backplate screw holes.
See
"Figure 3. Controller Components"
.
4. Secure the backplate to the box using the screws that
came with the electrical box.
5. Drill out a ½" hole and insert the round seal supplied with
the kit. A remote cable will run through the middle hole
of the backplate and into the electrical box.
2.5 Installation of the Backplate on a Flat
Wall
CAUTION
Do not expose the user interface to direct
sunlight. Too much direct sunlight will darken
the LCD screen, and it will no longer be
readable.
1. Turn off the pump at the control panel.
2. Turn off all electrical power to the pump at the main
junction box or at the circuit breaker providing electrical
power to the pump.
WARNING
ELECTRICAL SHOCK HAZARD
Turn off all switches and the main breaker in
the ePump electrical circuit before starting the
procedure. Failure to comply may cause a shock
hazard resulting in severe personal injury or death.
3. A minimum of two (2) fasteners (installer supplied)
are required when installing to a flat wall to hold the
controller securely.
4. The backplate has ten (10) mounting holes to choose
from. Only drill out the plastic film from the holes to be
used. See
"Figure 3. Controller Components"
.
5. Mark the hole locations on the wall and use the fastener
to secure the backplate to the wall.
6. At the bottom of the backplate, cut the two (2) tabs
out with an appropriate tool, such as a carton cutter or
an exacto knife, and route the cable through the open
channel.
2.6 Connection to Jandy Pro Series
variable-speed Pump
IMPORTANT
The installer must TURN ON switches 1 and 2 at the
pump when connected to the variable-speed controller.
The following steps provide the procedure for installing
the controller to a Jandy
®
variable speed pump.
1. Turn off all switches and the main breaker that
supplies power to the pump.
WARNING
ELECTRICAL SHOCK HAZARD
Turn off all switches and the main breaker in
the ePump electrical circuit before starting the
procedure. Failure to comply may cause a shock
hazard resulting in severe personal injury or death.
2. Remove the cover of the pump junction box.
3.
Feed the RS-485 cable into the fitting.
