View Full Version : outdoor walk-in installation
03-09-2006, 11:35 PM
Most of my business is residential. Some of these customers like me to do now also work in their businesses.
For a restaurant owner I need to install an outdoor walk-in cooler. The box is 10x10 with floor. I did an install of a freezer in a college refrigeration class, but you know how that works, one works and four watch.
I need to know now, how many man hours I need to calculate to but the box together and how many hours to install the refrigeration R22 outdoor condensing unit and the evaporator. I am looking for an average time, not for the fastest installer or the beginner.

From uncrating to start-up, 2 men - 2-1/2 - 3 days if you have to pipe it and install the membrane roof.

That's about right I'd say. Is this a new box or a used one? If it's used, all the camlocks are rusted and none of the panels are labeled........you're screwed.

Two guys that have experience building W.I. boxes should have it built, roofed, evap hung, and cond unit set in one day. Next day, ref and drain piping while electrician does his thing. Leak check, evacuation and start up. Could take a little longer for someone who doesn't do it that often but it's pretty easy. One word of advice though. Make sure everything is square and level, starting with the floor. Being it's an outdoor freezer, make sure it's tight, seal any gaps.

Build the box, install roof, hang coil and set condensing unit in one day. Pipe in refrigeration system and drain, evacuate and put in slight holding charge in easy day. Maybe longer if controls aren't pre-installed. Usually have to wait on electrician to wire, then come back and 2 hours or so to start up.
If you have to flash membrane to store building or do any build up to level the box it would add some time.
Like Ice said, if it's a used box they can fight you like crazy, don't tie yourself to a set labor price in that case. In it is used take a case of WD-40 and several tubes of silicone with you.

Thanks for all that good advice. I donít know if it will be a new box or not, both are options.
But I will let him put together the used box. He can take the risk involved. I do hope, he will buy a new condenser/evaporator or I can see him already unhappy, when I have to come back every couple of month due to a breakdown.
