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.
