Note for Tucson, Arizona Area Installations:

Certain building/electrical codes require the use of a

“P-26

Fuse Box,”

such as the G.E. Model No. T-U261F

rainproof power outlet fuse box, when wiring a cooler.

When using this fuse box, a fuse rated at 1.6 Amp might
be required for proper operation of the Power-Clean®
system vs. the smaller 1.25 Amp fuse. These fuses are a
type S time delay and must be used ahead of the cooler
pump and PowerClean® system.

Installation and Operating Instructions

CAUTION:

• Disconnect electrical power to cooler before installing your Power-

Clean® system or servicing cooler.

• Installation must comply with cooler manufacturer’s specifications

and all applicable building and electrical codes. For safety against
electrical shock, cooler cabinet, blower motor, pump(s) and
switch(es) must all be properly grounded.

INSTALLATION PROCEDURE:

1. Disconnect Electricity To Evaporative Cooler.
2. Unplug Existing Cooler Pump.
3. Place Pump Screen Onto Power-Clean® Pump.
4. Mount Power-Clean® Pump Inside Cooler.

Secure pump to

blower housing with mounting bracket.

5. Install Hose Adapter Into Overflow Pipe.

Place proper end of

hose adapter into overflow pipe. See markings on hose adapter.

6. Attach 1/2" Hose From Power-Clean® Pump To Hose

Adapter.

Securely attach hose onto pump. Connect other end of

hose onto hose adapter. Avoid kinking hose — cut hose if
deemed necessary.

7. Plug In Power-Clean® Pump.

Note the specially integrated

plug and receptacle on the Power-Clean® pump cordset.

8. Reconnect

Existing Cooler
Pump

into the

special Power-
Clean® pump
receptacle.

9. Connect Piping To Remove Cooler Water.

Do not allow

cooler water to run onto roof. Connect garden hose, or 3/4" PVC
piping from underside of cooler drain to an appropriate drain
site on the ground. Use of 45 degree elbows instead of 90
degree elbows is recommended. This will prevent unsightly roof
stains as well as potentially damaging effects to roof shingles.

10. Reconnect Electricity To Evaporative Cooler.

OPERATING:

Your Power-Clean® system automatically removes the water in
your cooler once every 8 hours that the cooler pad pump is “ON.”
This periodic draining replaces the “hard” water that naturally
develops in the cooler with clean, fresh water in a consistent
manner. The result is decreased scale build-up, longer pad life,
less cooler maintenance and lower water usage (compared to a
standard bleed-off system).

IMPORTANT:

1. Power-Clean® drains the water depth to less than 1/2 inch.
2. Use of a low draw or low operating level pad pump is highly

recommended to avoid developing dry pads during the draining
cycle. (Use Dial PowerCool™, Dial Contractor™ and Dial
HomeCool™ pumps.)

3. During the Power-Clean® draining cycle, both purge and pad

pumps are “on.”

4. If the Power-Clean® pump drains the cooler reservoir too fast,

the drain time can be extended by installing a pump hose
clamp (Dial PN 9282 or PN 9287) to the Power-Clean® pump
hose. This will decrease the water discharge rate (thus

extending the time required to drain the water reservoir) and
minimize any pad “dry-out” spots that might develop.

LIMITED WARRANTY:

1. Power-Clean® Purge Pump is warranted under normal use and

recommended maintenance for 2 years from date of sale to user.
In event of defect or failure, replacement is made through your
authorized dealer or retailer.

2. Reason for replacement, purchase date, and sales receipt

must

accompany pump returned for replacement.

3. Warranty is void if pump has been abused, altered, water

damaged or improperly installed.

4. We do not pay the cost of a service call at the site of installation

to diagnose cause of trouble, or the cost of labor or transportation
to replace a defective pump.

5. We are not responsible for any incidental or consequential

damage resulting from any malfunction unless required to do so
by state law.
