Q. How do I prevent freezing in a truck-mount carpet van?
- Leave your van running with the heater on high, initially at each job.
- Transport the solution hose inside the facility or home to keep it warm until you are ready to start cleaning. If needed, run the solution hose inside of a spare vacuum hose to protect from freezing. Never leave wands and sprayers outside as they can freeze in just a few minutes.
- Get your fresh water supply hooked up and the water moving. Make sure you have sink adapters as most outside faucets will be frozen or under snow.
- You can install thick black foam insulation made for water pipes over the feed line or at least in the places where it would touch frozen surfaces.
- Immediately run hot or warm water through the hoses and try to keep the flow going. Better yet, install a water supply tank in your van. Once you are set up, start your truck-mount, close all doors possible, and shut off the van engine.
- Preplan the entire job so solution is always running thru the water supply and solution hoses.
- When finished, reverse the process. Start the van and disconnect the quick disconnect (QD) from the truck and insert a spare (unattached) mating QD into it. Then disconnect the QD at the wand and do the same thing.
- Elevate the hose as you walk back toward the truck. This will drain the hose so it poses no threats of future freezing until you arrive at the next job.
- Empty the wand by attaching the mating QD to the wand and squeezing the trigger. Or, depress the male disconnect with a wrench while draining the water from the wand. When you hook up at the next job it only takes half a minute for the unit to purge the air and begin delivering heated solution.
Don't rule out the possibility of rescheduling a job when arctic temperatures pose a serious threat to your investment. No homeowner wants house doors standing open in freezing weather.
