RECOMMENDED INSTALLATION FOR ALL APPLICATIONS

(1) Electrical wiring and protection must be in accordance with National

Electrical Code and any other applicable state and local electrical

requirements.

(2) Install proper Clarus Environmental Unicheck (combination union and

check valve), preferably just above the basin to allow easy removal of

the pump for cleaning or repair. On sewage, effluent or dewatering, if

high head or below cover installation is required use 30-0164 on 1½"

pipe, 30-0152 on 2" pipe and 30-0160 on 3" pipe. See (4) below.

(3) All installations require a basin cover to prevent debris from falling into

the basin and to prevent accidental injury.

(4) When a Unicheck is installed, drill a 3/16" dia. hole in the discharge

pipe even with the top of the pump. NOTE: THE HOLE MUST ALSO

BE BELOW THE BASIN COVER AND CLEANED PERIODICALLY.

(High Head unit see #3 under “Caution” on front page). Water stream

will be visible from this hole during pump run periods.

(5) Securely tape or clamp power cord to discharge pipe, clear of the float

mechanism(s).

(6) Use full-size discharge pipe.

(7) Basin must be in accordance with applicable codes and

specifications.

(8) Pump must be level and float mechanism(s) clear of sides of basin

before starting pump.

(9) Basin must be clean and free of debris after installation.

(10) Gate Valve or Ball Valve to be supplied by installer and installed

according to any and all codes.

(11) Locate float switches as shown in sketches. The best place for the

“off” point is above the motor housing and positioned 180° from the

inlet. Never put “off” point below discharge on pump.

(12) Gas tight seals required to contain gases and odors.

(13) Install Clarus Environmental Pump Stand (Model 10-2421) under

pump to provide a settling basin.

(14) Wire pump to power through a Clarus Environmental watertight

junction box or watertight splice.

(15) Refer to SSPMA Effluent Sizing Manual for determining “on” - “off”

switches.

(16) Septic tank risers must be used for easy pump and filter access.

SINGLE PHASE WIRING INSTRUCTIONS

FOR YOUR PROTECTION, ALWAYS DISCONNECT PUMP FROM ITS POWER SOURCE BEFORE HANDLING. Single phase

pumps are supplied with a 3-prong grounded plug to help protect you against the possibility of electrical shock. DO NOT UNDER ANY CIRCUMSTANCES

REMOVE THE GROUND PIN. The 3-prong plug must be inserted into a mating 3-prong grounded receptacle. If the installation does not have such

a receptacle, it must be changed to the proper type, wired and grounded in accordance with the National Electrical Code and all applicable local codes

and ordinances.

“Risk of electrical shock” Do not remove power supply cord and strain relief or connect conduit directly to the pump.

Installation and checking of electrical circuits and hardware should be performed by a qualified licensed electrician.

Units supplied without a plug (single and three phase) and single phase nonautomatic units with a 20 amp plug must have a motor

control and liquid level control provided at time of installation. The control device should have suitable voltage, ampere, frequency, grounding and

horsepower rating for the pump to which it is connected.

IMPORTANT NOTICE: Some insurance policies, both commercial and residential, extend coverage for damages incurred by product failure. You

will need to have possession of the product to support your claim in most cases. Clarus Environmental will exchange the unit or refund the original

purchase price once the claim is settled with the insurer in the case where you need to retain possession of the product to support a damage claim

you submit to your insurance company.

On some installations it may be desirable

to install an independent hanger for the

level control switches to avoid possible

hang ups on the pumps, piping, valves,

etc. Float hangers are available from

Clarus Environmental or can be fabricated

from standard pipe and fittings.
