7. Freezing Weather Conditions
Your installer or system designer will provide you with special instructions
for what to expect and what to do during freezing temperature conditions
(below 32 °F). Spas installed in inclement weather areas should
incorporate electronic freeze sensors and utilize insulated safety covers
for economy and damage protection.
It is advisable to run filter cycles frequently and to check the equipment
system often during freezing weather. If an extended power outage
occurs, it is wise to drain each pump, filter, and heater through their
integral drain plugs and to trip the main equipment spa breaker to
prevent accidental start-up.
