CHANGING THE SWIM SPA WATER
The water in your swim spa must be carefully monitored
and drained regularly as required, depending on size and
amount of use. Draining at least once annually is strongly
recommended and offers the opportunity for inspec on of
jets and suc on fi ng covers. If your swim spa is used daily
or by a large number of bathers, the water should be
drained more o en. One method to determine the approxi-
mate length of me between water changes is to divide the
water volume (in liters) of you swim spa by 13.5 and then
divide by the average number of bathers each day.
EXAMPLE
:
1000 liters divided by 13.5 divided by 2 = 37 days. The swim
spa water must be changed when the amount of dissolved
solids becomes excessive, and is usually indicated by “gray”
or dull looking water.
DRAINING YOUR SWIM SPA
REFER TO FIGURE 1 & FIGURE 2
1 Locate nearest drain facility (Check your local bylaws) .
2 Put the hot tub control system into STANDBY/DRAIN
ASSIST mode. The system will automa cally exit
Standby Mode a er 1 hour and resume normal
opera ng func ons.
3 Remove the skimmer basket so that the hole beneath it
is accessible, and insert the #10 rubber expansion plug
or plas c threaded plug provided.
4 A ach garden hose to hose bib located on plumbing line
beside the hot tub control system.
5 Run garden hose to drain loca on.
6 Open hose bib.
7 Close filtra on pump return gate valve next to the hose
bib (this directs the water out the drain hose).
8 Ac vate the circ pump.
9 Monitor the swim spa while it drains.
10 Use the second garden hose to wash down interior
surface as the swim spa con nues to drain. A sponge
may also be used to wipe down the interior surface.
11 To completely flush the old water from the plumbing lines:
allow fresh water to fill into the foot - well area while the old
water con nues to be pumped out. Always keep at least
10cm (4 in.) of water in the foot - well so that pump 1
remains primed.
12 When the water from the drain hose turns clear (indica ng
fresh fill water), flush is complete.
13 Turn OFF the filtra on pump.
14 Close the drain - hose bib on the swim spa plumbing
line and con nue filling swim spa with fresh water.
15 Place cover on swim spa (to avoid splash - out).
16 Open filtra on pump return gate valve.
17 Press any bu on on the topside control panel (other than
the pump 1 bu on) to take the system out of STANDBY/
DRAIN ASSIST mode. Filtra on pump and the heater will
ac vate to circulate and heat the water while filling con n-
ues. This also reduces the possibility of an airlock occurring.
18 Con nue adding fresh fill water un l level is approximately
19mm (3/4 in.) from the top of the skimmer opening.
19 Once fill is complete, remove the #10 rubber expansion plug
from the bo om of the skimmer housing. *
20 If the filter housing was opened to replace the cartridge
filter, it will be necessary to release trapped air from the
filter housing by carefully loosening the small black air
vent/bleeder valve located on the top of the filter housing.
When water begins to escape close the air vent valve.
21 In the unlikely event of a pump air lock (pump 1 is opera ng
but there is no water movement from the jets), refer to
sec on
PUMP PRIMING/RELEASING AN AIR LOCK
*
It may be necessary to put system into STANDBY/DRAIN
ASSIST* mode in order to remove plug.
Never fill a swim spa with water from a water so ener, as it
could adversely effect the water chemistry, making it difficult to
maintain proper water balance. If you live in an area with hard
or so water, give careful a en on to your Calcium Hardness
level. Topping up with so water is acceptable.
