Operation

SAFETY RULES

1.Spa or hot tub water temperatures should never exceed 104° F. A temperature of 100° F. is considered safe for a healthy adult. Special caution is suggested for young children.

2.Drinking of alcoholic beverages before or during spa or hot tub use can cause drowsiness which could lead to unconsciousness and subsequently result in drowning.

3.Pregnant women beware! Soaking in water above 100° F. can cause fetal damage during the first three months of pregnancy (resulting in the birth of a brain-damaged or deformed child). Pregnant women should stick to the 100° F. maximum rule.

4.Before entering the spa or hot tub, the user should check the water temperature with an accurate thermometer. Spa or hot tub thermostats may err in regulating water temperatures by as much as 4° F.

5.Persons with a medical history of heart disease, circulatory problems, diabetes or blood pressure problems should obtain their physician's advice before using spas or hot tubs.

6.Persons taking medication which induce drowsiness, such as tranquilizers, antihistamines or anticoagulants should not use spas or hot tubs.

WARNING

Should overheating occur or the gas supply fail to shut off, turn off the manual gas control valve to the appliance. Do not use this heater if any part has been under water. Immediately call a qualified service technician to inspect the heater and to replace any part of control system and gas control which has been under water.

TWO-WIRE OR THREE-WIRE REMOTE HOOK-UP, (cont’d.)

• Three-wire remote:

a)Using 3/16" female quick disconnect connectors, connect the common wire to the "GND" tab of the temperature controller, then connect the two remaining wires to the temperature controller corresponding to the remote control device, pool wire to "POOL" tab, spa wire to "SPA" tab.

b)Now return power to the heater. (Note: If you used the main power switch to turn off the heater, now turn the main power switch on.) At this time, the remote system has control over the heater and if pool or spa temperature is below the temperature controller setting, then the heater will try to come on.

c)If you desire to reset the temperature settings of the temperature controller, the remote has to be in the desired mode for you to change the particular setting. Example: You wish to raise or lower the pool temperature from the factory setting, you must have the remote system in the pool mode, if you wish to change the spa temperature, you must have the remote system in the spa mode.

5.Now turn on the gas valve to "OPEN" position, the heater is now ready to operate.

NOTE

The heater factory settings are 78° F. for the pool and 104° F. for the spa. When connecting a remote control to the MiniMax, you must install the low voltage thermostat wires in separate conduit from ANY line voltage wires. Failure to follow these instructions will cause the thermostat relay to react erratically. A Remote hook-up deactivates the selector keys on the front thermostat display panel and gives selection control to the remote.

3 WIRE REMOTE

This icon is not a fault icon but instead indicates a remote switching device is connected to the Pentair Temperature Controller 7800, and has overriding selection control of Pentair Temperature Controller 7800.
