What type of a spa pump / system
do you have?
Contractor Installed spa in deck, with single speed
Usually, a single
speed spa pump will run at 3650 rpm constantly. In this instance, the best
settings for filtration is for about 2-3 hours per day total running time. Best
way to set this up is for twice daily, about 1 to 1.5 hours each
- Spa with two speed pump and
Most portable spas are set up this way, and also some better
contractor built spas. Most of these are intended to be set up running on the
clock 24 hours per day, continuously heated on demand, as determined by the
thermostat setting. Normally, a spa like this will operate on low speed when
filtering and heating, so, the Filter Timer should be set to filter the water
from 4-6 hours per day, ie, two settings of 2-3 hours each.
1. Filter Timer
Equipped Only. On this type of spa control, there is usually a two or three
position switch that controls the heater and pump operation. Positions will
usually indicate something like:
Timer controls Filter and
Timer controls Filter,
Thermostat controls Heater
For optimum results,
you should set the switch to where the Timer Controls Filtering, and Thermostat
2. Filter Timer and Heater Timer Equipped. There are a few
spas that fit into this category, namely those that utilize Brett Aqualine Spa
Controls, and a few others.
On these spas set the timer to
filter the spa by the timer for 4-6 hours daily. Now usually, the heater timer
is a 7 day type. You have two choices here. If the spa has a heater option
switch with the timer, it can be set to either operate only on the days and
times that you desire, or just have the thermostat control the heater full
time. I generally prefer to let the spa stay hot, and the system controlled by
the thermostat, and filter timer.
3. No Timers, Just a
Thermostat. In this arrangement, all you can really do is set the
thermostat and hopefully, enough heat demand will be present to operate the
pump and subsequently filter the water satisfactorily. If it doesn't,
then turn the spa jets on for about 30-45 minutes every two days or so, or as
necessary. Many small spas do not have timers, and depend on heat demand
to operate the pump filtration system.
