Typical Installation Tools

WARNING: Injury or death may occure by electricution. Only experienced service technicians should enter the AC.
1.  Locate the relay in the electrical compartment of the AC.
2.  Connecting the wire harness
AC Mounted:  

a.  Position with 6mm tube outlets at a height 2/3rd from bottom of cooling fins.

b.  *Drill a 1/2" hole for the hook (bushing) wire connector to be inserted into the electrical access compartment.

c.  Use **silicone to protect the drilled hole (form a gasket). Insert the hook into the drilled hole then push upward to lock into position.

d.  **Use only 1 self drilling screw through the single eyelet under the CMB.  The two screw ears at the top of the CMB are only used on a non-AC-mounted application.

e.  Connect wire harness to the wiring connector.

*Do not obstruct WARNING or SCHEMATIC labels, relocate or contact manufacturer for new label(s) to reposition. 

**Recommended:  Applying silicone sealant on drilled holes will protect exposed raw metal from rusting.
3.  Mounting CMB (Control Module Box)
Lay out your application, using extra tubing.  Suggestion:  Mark the top of the AC edge to determine the distances from CMB to tip and tip to tip.  The tubing can be stretched, made tight and shortened accordingly, to easily create the best fit.

a.  If using the corners for a squared AC, carefully insert longer tubing to be cut to size later.  

b.  Cut-in T-Nozzles to be centered in front of each set of cooling fins.  Change tips later:  Twist-on-tips are provided in 3-sizes, for each T-Nozzle, to work with any application.

c.  After assembled, trim tube where appropriate to make tight, securing around the AC.
4.  Construct spray sling
with tube, T-Nozzles & Corners (if AC is not rounded)

5.  Connecting to a Water Supply
a.  The Hose Bib Adapter has one open (operating) and one closed (stow/winterize) nipple.   Attach to any standard male hose valve connection with clean, 40-120 psi, water.

b.  Use a straight connector on the Hose Bib Adapter to connect 8mm supply tube (Use ONLY ACEnergySaver tube for the highest UV inhibitor) to the CMB.

c.  Two Elbow-drains should be inserted at the lowest points to automatically drain the supply tube when the supply pressure is released.  In an application where the CMB is mounted OFF the AC, the system will drain each time the AC shuts off (see alternative mounting).

A "Y" (on a home faucet) is recommended to keep the Hose Bib adapter permanently connected by making a spare connection available.

The ACEnergySaver's ultra-fine filter can be cleaned by simply rinsing the screen cartridge. 
  • 1/2" metal drill bit & Drill
  • 7/16" driver (to drive self drilling screws)
  • Tubing cutter
  • Electrical tester
Be sure to mark the installation date on the CMB.

a.  Use 7/16" driver to open the electrical compartment.

b. *Measure the low voltage to determine if the low voltage terminals are
    A single 24 volt terminal or Two separate 12 volt terminals

*Adjust thermostat to activate the relay, providing the current to be measured.

7. Special installation for
Seasonal (winterized) homes
Most homes in hot, humid climates will usually be left with an air conditioner running at a high setting, to protect the home from moisture damage.  Additionally, these homes will often be left with the water main shut off, as an additional safety measure.

The ACEnergySaver is the best way to protect the air conditioner by reducing wear and electricity consumed.  This section instructs how to prepare the water supply to accomodate this scinerio.

Additional tools and supplies needed for a 3/4" PVC water main:

  • PVC cement and purple primer
  • PVC cutter
  • Teflon tape
  • Shut off ball valve (3/4" is typical)
  • 3/4" X 3/4" X 1/2" Female NPT
  • Boiler valve (to attach the filter and hose bib adapter)

*Use other materials for non-PVC applications or that which is not 3/4", respectively.  Consider using ​speed connections such as SHARK BITE fittings to connect different materials.  These are available at all large home building supply and plumbing stores.


1.  Shut off water main.
2.  Cut pipe above the main, leaving enough to glue a fitting onto or attach a speed fit (see photo example).
3.  Attach a Tee with a female thread (1/2" NPT) to
4.  Attach a boiler drain (house spigot/faucet) using teflon tape on the threads 
5.  Attach another valve above the Tee.  This new valve will be used as the water main, leaving the original water mail open.  This application will allow shutting off water to the home while allowing the ACEnergySaver to have water.
6.  Attach ACEnergySaver FILTER, HOSE-BIB-ADAPTER, 8MM COUPLER & 8MM SUPPLY TUBE from this new connection.

              Piggyback connectors enable sharing terminals. 

Case #1 - Single 24 volt terminal:
    a.  Connect one piggyback to the 24 volt terminal and
    b.  Insert Ground Adapter A into the second piggyback and ground to the steel housing, under a sheet metal screw.

Case #2 - Two separate 12 volt terminals: 
    a.  Connect piggyback connectors to *each 12 volt terminal. 
    b.  No ground is required.
        *12 volt terminal connections are on separate legs.
