MAINTENANCE AND OPERATION

MAINTAIN PROPER WATER FLOW

• It is important to operate and maintain the filter according to the manufacturer's

specifications. As a filter gets dirty, the water flow to the heat pump is reduced.

The higher the pressure on the filter gauge, the lower the flow rate.

• Similar to a dirty filter, large amounts of debris in the pump and skimmer baskets

can reduce water flow. Keep baskets free of debris.

• Check for improper valve settings. A partially closed valve after the filter, or a

full-open bypass around the heater, will cause insufficient water flow through

heater.

• If the conditions listed above remain unresolved, the water flow through the

heater may be reduced to a point where internal safety devices (i.e.: "HP" or

"HP5") shut the heater off.

• Before calling for service, always check the filter, the pump basket, and water

valve positions. If the problem persists, please call Aquatherm at: 239-482-0606

MAINTAIN PROPER WATER CHEMISTRY

• IMPORTANT! Your heat pump is engineered for exceptional durability

and reliability. This unit's heat exchanger—being equipped with titanium

tubing—will be nearly impervious to water chemistry damage. However, other

components of the heater, and the remainder of the pool/spa equipment in

general, may be susceptible to damage from prolonged exposure to unbalanced

water chemistry. There can also be health risks involved with improper water

chemistry

• For the longevity of the entire pool/spa installation, and for the safety of users,

it is strongly recommended that the water chemistry be checked regularly and

maintained within proper norms. The table below lists recommended water

chemistry levels.

USER LOCK CODE OPTION [ULC]:

Heat pumps are shipped from the factory with the [ULC] option disabled. En-

abling the [ULC] function permits the heat pump owner to restrict access to the

unit's controls. With the [ULC] function enabled, unless the correct ULC code

number is entered, changes to Level-1 programming are not possible. (I.e.: Alter-

ing temperature set points, Pool/Spa selection, C/F display changes, etc., will not

be possible). The [ULC] option can be thought of as an electronic lockable cover

for the controls.

A. SELECTING ULC OPTION:

1) Press either the UP or DOWN ARROW keys; if "LOC" is momentarily dis-

played followed by "0", the ULC feature is enabled. If "0" displays proceed

to "6)" of this section; otherwise, see number "2," below.

2) Simultaneously press and hold both the [UP ARROW] and [DOWN ARROW]

keys until [CF1] (Celsius / Fahrenheit) code appears.

3) Press the [POOL/SPA] key once to display [ULC].

4) With [ULC] displayed, pressing either the Up or Down Arrow key will display

either "1" or "0". Selecting "0" will allow the keypad to remain unlocked.

Selecting "1" will enable the User Lock Code option. Then, to enter a lock

code number, press the [POOL/SPA] key once to display [ELC] (Enter Lock

Code).

5) With [ELC] displayed, use the Up or Down arrow keys to select a lock code.

The code can be any number from "00" to "99". The factory set lock code is

"0". Not pressing any buttons for 15-seconds will allow the controller to save

the selection and return to the normal operating mode. Pressing the {POOL/

SPA] key will also save the selection, and will step the controller to the next

menu parameter: [CFO] (Call Flex Options).

6) Once the ULC option has been enabled, pressing any key will momentarily

display "LOC" followed by "0" (prompting the entry of the correct lock code

number). To gain access to the controller:

a. Using the [UP ARROW] key, scroll to the correct lock code number,

then;

b. Press the [POOL/SPA] key... Current water temperature will be dis-

played... Control setting can now be viewed or changed as desired.

c. After a period of approximately four (4) minutes, during which time no

buttons have been pressed, the controller will automatically return to the

locked mode. Provided ULC selection is set to "1," the controller will

always fail-safe in the locked mode.
