mY SPA IS to Hot IN SUmmeR!
During summer months in hot climates, there may be times when the actual water
temperature exceeds the desired temperature set by the user. E.g. If the spa is set to heat
to 35°C, but the actual water temperature is 38°C. Please consider this - In the Winter
your spa gets cold because the air temperature is cold. To combat this we heat the water
& keep the spa covered when not in use. If the spa is turned off & the ambient temperature
is 15°C, eventually the spa water will lose heat until it too is 15°C. In the summer the same
applies but in reverse - you can turn the heater down, even turn the pump off, but if the
ambient daytime temperature is 35°C - 42°C then the spa water will also remain at that
temperature.
Manufacturers make no attempt to supply a system that cools water. The quickest way to
combat the problem is to change the water, but even this new water will eventually heat up to
the air temperature. Turn the set temperature down so the heater does not come on. Reduce
the minimum filtration time so the pump runs less. The less the pump runs the more the water
will cool. If the nighttime temperature is low, leave the cover off the spa to let heat escape, but
put it back on during the day to keep heat out. Also make sure the spa is shaded from direct
sunlight.
WARNING: Before using ensure that the spa pool has been connected to a suitable weather protected
outlet socket, equipped with a double pole isolating switch, which is of the correct rating and complies with the
local wiring regulations.
When installing, refer to your local wiring code. In particular refer to ECP2 & ECP25 (AS/NZ) and EN60364-
4-1 & EN60364-7-1 (EU). The system must be installed in such a way that live parts are not accessible by
a person in the pool. If a supply cord is not fitted the system must be permanently connected to fixed wiring
through a 30mA or less RCD.
It is recommended that the steel reinforcing in any concrete base on which the pool is sitting be equipotential
bonded to the earth conductor in the supply to the spa. This is to protect against the possibility of low voltage
shocks caused by differential earth voltages. Refer to AS/NZS3000:2000 Sections 5.8 & 7.2 or EN 60364.
WARNING: This appliance is not intended for use by young children or infirm persons without supervision.
Young children should be supervised to ensure they do not play with the appliance.
WARNING: This product must be covered by an enclosure to prevent water ingress.
If the supply cord is damaged, it must be replaced by Davey, a Davey service agent, or a
similarly qualified person in order to avoid a hazard.
