SHUT OFF VALVE MUST BE INSTALLED AT INLET OF UNIT. ELECTRICAL AND PLUMBING
CONNECTIONS MUST BE FOLLOWED TO MEET ALL LOCAL CODES AND REQUIREMENTS.
After tightening both fittings at the water heater, RUN our pump to allow water to run through
the Spa/Pool heater for at least 5-10 minutes. This process purges all the air from the water lines
and MUST be performed prior to turning on the power at the unit.
FAILURE TO FOLLOW THIS STEP
CAN CAUSE PERMANENT DAMAGE TO THE HEATING ELEMENTS.
Water Flow-Your Spa/Pool heater must have an adequate flow of water flow for proper operation.
Adequate water flow removes the heat produced by the heater and transfers the heat to the Spa/
Pool and prevents overheating. Low water flow usually results from dirty filter or improperly ad-
justed manual by-pass. Manual by-pass valves should be set so that the outlet temperature com-
ing from the heater is 6-8 degrees F. above the Spa/Pool water after five (5)minutes of heater op-
eration. This can be measured using a thermometer.
When any maintenance is performed on the Spa/Pool that may introduce air into the plumbing
pipes, it is important to turn the power off to the Spa/Pool heater and purge the air out of the
lines before allowing the unit to power up.
DRY-FIRINGofELEMENTS:
caused by water voids when power is on. ALL air must be purged from
system before any heat start-up. It is IMPORTANT to purge all air after cleaning or changing a car-
tridge filter. The filter casing acts as an air reservoir during this procedure, the circulation system
must be on for at least 2 minutes before you turn power on.
