For non-purged/pressurized models the outlet of the tube should be open to air,
not
submerged
in water or a process, which would cause a backpressure. This would result in an overflow
inside the chamber.
For purged/pressurized models, a slight and constant backpressure is required to maintain a
cabinet pressure. To accomplish this, submerge the effluent tubing approximately 10 cm below
the water surface or run the outlet tube with a slight upward grade prior to the downward outfall
such as a U-Trap. Be sure the tube never rises higher than the bottom of the chamber outlet.
8)
Note that the outlet is a gravity feed line only. The outlet tube must NOT rise above the bottom
of the lower chamber or be connected to a pressure process line.
9)
Confirm that the tray and flow plate are securely in place. Slowly open the inlet water source to
allow a steady and even flow over flow plate. Once the flow connections are verified and
operational, turn the water source off to continue with the electrical installation.

PERMANENT POWER CONNECTION (AC POWERED MODELS ONLY)
1)
Connection to the building wiring system shall be in accordance with the Canadian Electrical
Code (CEC), Part 1 in Canada, the National Electrical Code, ANSI/NFPA 70 in the USA, or the
local electrical codes of the country where the equipment is being installed.
2)
An external mains switch or external over-current protection / circuit breaker device is required
as a disconnect device. This mains disconnect device shall be specified as complying with the
requirements of IEC 947-1 and IEC 947-3.
3)
The external mains switch shall be in close proximity to the equipment and within easy reach of
the operator. The switch shall be marked as the disconnecting device for the equipment and
include the symbols to its “ON” and “OFF” positions using the following symbols:
Power Off
Power On
4)
The wiring for AC power should be 14 – 16 AWG / 300V or as required by local / country codes.
5)
After field wiring, the primary wires must be secured to the enclosure by tie-wraps to maintain
the separation from the signal wires.
6)
The equipment is suitable for connection to a 15A protected branch circuit.
7)
Wiring diagram for permanent connection: See drawings at the back of this manual.
