Maintaining Spa Water 
Poor water quality can be extremely hazardous to your health. 
We recommend you do following things: 
A: Please use filter cartridge. 
Screw the filter onto the water inlet (lower fitting) on the spa wall by turning it clockwise. 
Note:Two filter cartridge, one is for use, one is spare. 
Note: Do not use filter cartridge when only to heat water or to ensure 
good heating performance. To avoid that the filter cartridge get damaged, 
do not use the filter when there are children or more than two persons in 
the pool. After finish using, replace the filter cartridge. 
B: Clean your filter cartridge at least once a time after it worked continuously for 72~120 hours. The filter 
cartridge should be replaced at least once a month depending on use. 
Please make sure to unplug the power pack from the 
electrical receptacle before the following actions. 
1. Unscrew the filter cartridge by turning it counterclockwise. 
2. The Filter Cartridge can be rinsed off with a garden hose 
and reused. However, if the Filter Cartridge remains soiled 
and discolored the Filter Cartridge should be replaced . (1) (2) 
The MSpa filter cartridge has a lifetime of approx. 6 weeks even it’s well maintained. If the paper wall in the 
filter still looks new, it means the filter can be used for a few more weeks. We suggest preparing more than 
one filter so you can switch between the two filters when one of them is being cleaned. Make sure the filter 
must be totally dry up before use again. If dusts in the water looks obvious, change the filter frequently. 
C: Change water every few days or use appropriate pool chemicals. All spas require the use of pool chemi- 
cals. Please consult your local pool supply retailer for more information about chemical maintenance. Pay 
close attention to the chemical manufacturer’s instructions. Spa damage resulting from misuse of chemicals 
and mismanagement of spa water is not covered by the warranty. 
a. Water Balance: we recommend maintain your water pH between 7.2 and 7.8, total alkalinity between 80 
and 120ppm and free chlorine between 3 to 5ppm. Use test strip to test your water chemistry before each 
use of the spa, no less than once per week. Low pH will damage to the spa and pump. 
Damaged resulting from chemical imbalance is not covered by the warranty. 
b. Water Sanitation: Water Sanitation is the responsibility of the spa owner, achieved through the regular 
and periodic (daily, if necessary) addition of an approved sanitizer. The sanitizer will chemically control the 
bacteria and viruses present in the fill water or introduced during use of the spa. 
Note: 
1. Leftover chemical from any sources should not be used in the spa tub. 
2. Use chlorine powder not tablets to clean the water. Dissolve the power before pour into water. 
3. Do not mix the water with any bath oil or bath salt. 
4. Only use clean water to fill the spa tub. Salted water could damage the pump and filter.
