WaterGroup WG185ACF75, Owner'S Manual

1. If your hot water tank is electric, turn off the power to it to avoid damage to the element 

in the tank. 

2. If you have a private well, turn the power off to the pump and then shut off the main wa-

ter shut off valve.  If you have municipal water, simply shut off the main valve.  Go to the 
faucet, (preferably on the lowest floor of the house) turn on the cold water until all pres-

sure is relieved and the flow of water stops. 

3. Locate the filter tank close to a drain where the system will be installed.  The surface 

should be clean and level. 

4. Connect the inlet and outlet of the filter using appropriate fittings.  Perform all plumbing 

according to local plumbing codes. 



Use a ½” minimum pipe or tubing size for the drain line 



ON COPPER PLUMBING SYSTEMS BE SURE TO INSTALL A GROUNDING 
WIRE BETWEEN THE INLET AND OUTLET PIPING TO MAINTAIN GROUND-

ING. 

Any solder joints near the valve must be done before connecting any piping to the valve.  

Always leave at least 6" (152 mm) between the valve and joints when soldering pipes that 

are connected to the valve.  Failure to do this could cause damage to the valve. 
 

5. Connect the drain hose (10 ft included) to the valve and secure it with a hose clamp (also 

included).  Run the drain hose to the nearest laundry tub or drain pipe.  This can be ran 

up overhead or down along the floor.  If running the drain line more than 20 ft overhead, 
it is recommended to increase the hose size to 3/4”.  NEVER MAKE A DIRECT CONNEC-

TION INTO A WASTE DRAIN.  A PHYSICAL AIR GAP OF AT LEAST 1.5” SHOULD BE USED 

TO AVOID BACTERIA AND WASTEWATER TRAVELLING BACK THROUGH THE DRAIN 
LINE INTO THE FILTER. 

6. Using the Allen Key (included), place the unit in the bypass position.  Slowly turn on the 

main water supply.  At the nearest cold treated water tap nearby remove the faucet 

screen, open the faucet and let water run a few minutes or until the system is free of any 

air or foreign material resulting from the plumbing work. 

7. Make sure there are no leaks in the plumbing system before proceeding.  Close the water 

tap when water runs clean. 

8. Proceed to start up instructions. 

Note:  The unit is not ready for service until you complete the start-up instruc-

tions.
