Watts Radiant WQC4 RO 사용자 설명서

1. Low/Slow Production  

Low Water Pressure 

 

Assure a minimum of 40 psi incoming water pressure.

 

 

 

 

 

 

 

Watts sells a booster pump if home water pressure is

 

 

 

 

 

 

 

low.  Make sure water supply is turned on and Adapta 

 

 

     Valve 

is 

all 

the 

way 

open.

 

 

 

Crimps in tubing 

 

Check tubing and straighten or replace as necessary.

  

 

Clogged 

pre-fi lters 

 

Replace pre-fi lters.

 

 

 

Fouled membrane                       Replace membrane and clean fl ow restrictor. 

                                                    Tank valve closed                        Open valve on storage tank

2. Milky colored Water   

Air in system 

 

 

Air in the system is a normal occurrence with initial start 

 

 

 

 

 

 

 

up of the RO system.  This milky look will disappear 

 

 

 

 

 

 

 

during normal use within 1-2 weeks.  If condition reoccurs

 

 

     after 

fi lter change, drain tank 1 to 2 times.

3. Water constantly  

 

Low water pressure 

 

See #1 Above

running/unit will not
shut off 

 

 

Fouled membrane 

 

Replace membrane

 

 

 

High water pressure 

 

Check incoming water pressure to make sure it does not

 

 

 

 

 

 

 

exceed 100psi. A pressure relief valve may be necessary.

 

 

 

High air pressure in tank 

Empty storage tank of water. Set tank air pressure to 5

 

 

     psi. 

See 

Page 

15.

4. Noise from faucet or drain 

Air gap faucet   

 

Inherent sound with air-gap faucets.

 

 

 

Location of drain saddle  

See diagram for proper location of drain saddle. 

 

 

 

Higher capacity membrane 

Normal with high capacity membrane

 

 

 

High water pressure 

 

Check incoming water pressure to make sure it does not

 

 

 

 

 

 

 

exceed 100psi.  A presser relief valve may be necessary.  

5. Faucet leaks from 

 

Crimp or loop in drain line 

Straighten black 3/8 drain tube.  Cut off any excess tubing

the air gap feature   

 

Drain tube clogged/restricted 

Caused from dishwasher or garbage disposal.

 

 

 

 

 

 

 

Disconnect the 3/8” black tube at the drain, clean the 3/8”

 

 

 

 

 

 

 

black tube out with a wire, then reconnect.  

6. Small amount of water in  

System just starting up   

Normally it takes 6-10 hours to fi ll tank.  Note: Low

storage tank 

 

 

 

 

 

 

pressure and/or temperature can drastically reduce

 

 

     production 

rate.

 

 

 

Low water pressure 

 

See #1 Above

 

 

 

Too much air in tank 

 

Add air if below 5 psi and bleed if above 5 psi. Check 

 

 

 

 

 

 

 

only when tank is empty of water.  See Page 15.

   

 

7. Water leaks from the   

Not properly tightened.   

Tighten the bowl

fi lter housing 

 

 

Missing or kinked O-ring  

Turn off the water supply.  Release the pressure, remove 

 

 

 

 

 

 

 

bowl and replace the O-ring.  (p/n 113043). Make sure    

 

 

     the 

O-ring 

is 

seated 

in 

the 

fi lter bowl properly before 

 

 

     reinstalling 

the 

fi lter bowl.
