Winterizing Retardant System
3.9.1 Why Winterize Retardant System
If water is allowed to freeze in the retardant system, serious damage to the hose
system and the pump may occur.
Failures of this type will void the warranty of the pump.
Pump fails to deliver water (wetting agent) to nozzles due to freezing in spray sys-
tem.
The best guarantee against damage is to completely drain the retardant system of all
accumulation and/or use of water in system.
DO NOT use automotive antifreeze to winterize
retardant system. Such solutions are highly toxic.
Ingestion may cause serious injury or death.
3.9.2 Winterizing Retardant System Procedures
To properly drain the system, perform the following steps:
1) Drain the retardant tank completely of any water. disconnect bottom hose
attached to outlet on tank to allow the water to drain.
2) While bottom hose is disconnected, turn pump ON and allow the pump to purge
the water from the hose system, then turn pump OFF.
3) Using an appropriate container to catch the remaining water, disconnect all hoses
that are attached to the pump’s inlet and outlet ports. Turn the pump ON, allowing
it to operate until the water is expelled. Turn OFF power to the pump once all
water has been expelled from the pump. Do not reconnect pump hoses at this
time. Make a note at tank filler as a reminder: “
Hoses Are Disconnected for
Winterizing
Service
”.
4) All pump ports and tank bottom hose must be left open to guard against any
freeze
damage.
