6.
Set the thermostat to the desired temperature.
Until the pool water reaches a temperature of
approximately 70°F (21°C), there may be
condensate on the heat exchanger. This will stop
after the water reaches the right temperature.
If the heater is installed in an enclosed area, keep
all doors and windows open during the first two hours
of operation. After a long shutdown, there may be
some smoke-like emissions from the heater when it is
first fired. This condition will only last a few minutes.
7.5. Setting the Time Clock
The most economical and trouble-free way of
operating a pool heater and filter system is to include a
time clock in the system for automatic cycling.
Adjust the stops on the time clock to provide a
single filter cycle every 24 hours.
The ON cycle should be at least 12 hours to
allow the filter system to properly clean the pool. Set
the ON cycle at least 4 to 6 hours before the pool is to
be used. During cold spells, the heater may have to be
on longer to maintain the proper pool temperature.
Remove all stops on the time clock during these
periods.
IMPORTANT:
Run the heater continuously
during the initial warm-up period by removing all time
clock stops. If the pool temperature is going to be
maintained on standby temperature, operate the filter
pump until the water temperature reaches 70°F
(21°C). If the pool is going to be used for swimming,
bring the water up to swimming temperature before
replacing the time clock stops.
When the water reaches the temperature level
on the thermostat, the heater will turn off
automatically, but the filter pump will continue to run
for about 20 minutes.
7.6 Adjusting the Water Pressure Switch
CAUTION
The water pressure switch should be adjusted to turn
the heater off when the pump is off. Setting the
switch to close at too low of a flow can damage the
appliance. Adjust the switch to turn the heater off,
not on.
The pressure switch is preset at the factory for
activation at 2 psi (14 kPa). However, it is adjustable
in the range of 0.5 psi to 15 psi. Adjust the pressure
switch
only
if any part of the filter system piping or
water level of the pool is 3 feet (0.91 m) or more
above or below the top of the heater jacket.
Do not adjust the pressure switch if the heater is
installed more than 15 feet (4.57 m) below or 6 feet
(1.83 m) above the pool surface. Consult your local
Jandy representative for recommendations.
On some installations, the piping from the heater
to the pool is very short. The back pressure could be
too low to trigger the pressure switch. If this happens,
it may be necessary to install a directional fitting or
elbows where the return line enters the pool. This will
increase back pressure enough for the heater to
operate properly.
Make sure the pool filter is clean before making
any pressure switch adjustment: A dirty filter will
restrict the water flow and the pressure switch cannot
be adjusted properly.
To adjust the pressure switch, proceed as
follows:
1.
Set the heater control to the "OFF" position.
2.
Start the filter pump and confirm by means of an
meter that the pressure switch closes. If the
switch fails to close, slowly turn the thumb wheel
on the pressure switch counterclockwise (when
looking at the electrical connections end of the
switch) until the switch closes. If the switch still
fails to close call your Jandy representative or the
Water Pik Technologies Technical Service
Department at 707.776.8200 extension 260.
3.
Turn the thermostat to the maximum setting and
set the heater control to the 'ON' position. The
heater should start.
4.
Turn the thumb wheel on the pressure switch
very slowly clockwise until the heater goes off.
5.
Slowly turn the pressure switch thumb wheel
counterclockwise
one-quarter turn. The heater
should come back on.
