VSP 2018 Operations Manual

6.4.1.2 Water Quality

6.4.1.2.1 Changed (10)
The WHIRLPOOL SPA water, including compensation tank, filter
housing, and associated piping, must be changed every 72 hours,
provided that the system is operated continuously and that the
correct water chemistry levels are maintained during that period,
including daily shock halogenation.

SPA POOL water must be changed as often as necessary to
maintain proper water chemistry. The water must be changed at
least every 30 days.

The date and time of WHIRLPOOL SPA and SPA POOL water
changes must be recorded in the log.

6.4.2 Halogenation

6.4.2.1 Residual Halogen

6.4.2.1.1 Prolonged Maintenance (10)
For facilities undergoing maintenance for longer than 72 hours, the
free HALOGEN residual and pH levels must be maintained or the
entire system must be drained completely of all water. This
includes the WHIRLPOOL SPA and SPA POOL tubs,
compensation tanks, filter housings, and all associated piping and
blowers.

Records must be maintained for the free HALOGEN and pH levels
or the complete draining of the system.

6.4.2.1.2 Shock Halogenation (10)
The free residual HALOGEN must be increased to at least
10.0 MG/L (ppm) and circulated for at least 1 hour every 24 hours.

The free residual HALOGEN must be tested at both the start and
completion of shock halogenation.

The water in the entire RWF system must be superhalogenated to
10 ppm to include the WHIRLPOOL SPA/SPA POOL tub,
compensation tank, filter housing, and all associated piping before
starting the 1-hour timing.

HEATED ACTIVITY POOLS, including interactive RWFs, that
have features that break the water surface of the RWF or create a
mist must be shock halogenated as described. This includes
