INSTALLATION
OPTIONAL:
GCV3412 Code Valve Installation Instructions* Copper Pipe:
1. CAUTION: Turn off water supply.
2. Clean pipe, fittings and valve with sandpaper or wire brush.
3. Apply a thin layer of flux to all surfaces to be soldered.
4. Assemble valve to pipe and/or fittings.
WARNING: For your safety, the following should be performed by
a licensed contractor only.
5. Option: To prevent damage to the code valve while soldering,
cool the valve by wrapping a wet rag around the body of the
valve.
6. Heat the joints with a torch. Apply solder to each joint.
Continue to apply heat sufficient to keep solder liquid.
7. After solder has filled the entire joint area, remove heat and
allow the joint to cool. Do not move or disturb.
8. Slide compression nut over 1/4” copper tube followed by
compression sleeve.
9. Insert tube into valve fully and tighten nut.

5Mount the self-tapping saddle valve on either a cold or a hot
water pipe. A side or top mount is best to avoid clogging from
pipe sediment. Connect 1/4” O.D. tubing to the saddle valve.
• Copper tubing requires a brass compression nut and
brass sleeve.
• Plastic tubing requires a brass insert inside the
tubing, a plastic sleeve on the outside with a brass
compression nut.

Test the Operation of the Unit
• Turn the damper knob to the WINTER position.
• Turn on the water supply.
• Turn the humidistat ON (towards the left).
• The solenoid valve should be closed when not energized.
• Once the solenoid is energized the valve should open.
• Check flow of water through distributor trough and
evaporator pad.

Connect the 1/2" ID drain hose to the spout on the humidifier cabinet using
the provided flat spring clip. Run the drain hose to a suitable drain such as
floor drain, laundry sink or to a condensate pump (sold separately). Be sure
the hose has continuous slope and is not kinked at any point.
Connect 1/4" water supply tube to brass inlet of solenoid.
• Turn on water supply and check for leaks.
CAUTION: Do not use plastic tubing in contact with any hot
plenum surface or duct.
