OPERATIONAL & MAINTENANCE

RECOMMENDATIONS

The information in this section is primarily for the Home Owner, but may also

apply to servicing dealers or HVAC service centers. This section contains infor-

mation concerning planned maintenance, proper water flow, maintaining proper

clearances, as well as other vital information.

Heat pumps should be inspected and maintained on an annual basis by a qualified

swimming pool heat pump specialist. Additionally, if the heat pump is located near

the beach or coastal area, where salt spray and sand can become detrimental fac-

tors, more frequent service may be necessary. For service plan information, please

see: Planned Maintenance Program, later in this section, or contact Aquatherm

Customer Support at: 239-482-0606

While annual maintenance is recommended to maintain your warranty, if you

choose not to participate in the Planned Maintenance Program, rinsing the air coil

regularly, and keeping the base of the unit clear of leaves and debris is a necessity.

Safety During Cleaning Operations

Failure to heed the following may

WARNING !

result in permanent injury or death.

POSSIBLE ELECTRIC SHOCK HAZARD . . . Should you decide to wash

the heat pump via water hose, disconnect all power to the pool equipment

pad- including, but not limited to: The heat pump, water pump, and any and

all other electrical equipment. Do NOT spray water directly into electrical

components. Do NOT restore electrical power until such time as all water

has dried completely.

Failure to heed the following may

CAUTION !

result in damage to equipment.

Do not use a pressure cleaner to wash heat pump . . . .

Damage to evaporator fins, as well as other components,

will result.

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. And, 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. Likewise, bathers may be exposed to health risks if water

chemistry is not properly maintained.

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

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

maintained within proper norms. Please see the table, below, for a complete

listing of recommended water chemistry levels.
