water level is at least 2" above the filter area. If any part of the filter is above the water
level, it introduces air into the pump causing air lock, low water pressure, pump surging,
damaged heaters, and overheating.
CIRCUIT BREAKERS
Hot Tub equipment is often suspected of causing GFCI circuit breakers to trip. The
problem is usually caused by under-rated or old breakers. Before inspecting the
equipment, it is important to verify the breaker's rating. If a new and properly rated
breaker has been installed and it continues to trip, turn the power off to the Hot Tub and
have your electrician check the following:
1.)
Make sure the 3- or 4-wire connection is correct to the power pack.
2.)
Check for any loose connections inside the power pack.
3.)
Make sure the GFCI is wired according to local codes and the installation
instructions enclosed with the GFCI.
TEMPERATURE CONTROL
Always make sure you use a new thermometer. On occasions, your Hot Tub temperature
may read one or two degrees hotter or colder than your thermometer. This is normal and
is due to the tolerances of thermometers and the temperature probe in the Hot Tub.
Whenever the motor runs, ambient heat is generated. This ambient heat in the equipment
area helps maintain the Hot Tub temperature; therefore, keeping the cost of operation to a
minimum. On occasions, ambient heat may cause the Hot Tub temperature to rise a few
degrees above the set temperature. If you would like to lower the temperature, remove
the cover to allow the Hot Tub to cool to the desired temperature. Also, lower the set
temperature a few degrees to offset the ambient heat.
