Dowfrost
I I m m p p o o r r t t a a n n t t : : Dowfrost inhibited propylene glycol-based
solution is listed as chemically acceptable
by the US Department of Agriculture
(USDA). The two ingredients in Dowfrost
water/glycol mixture are generally
recognized by the FDA as safe food
additives under Parts 182 and 184 of the
Food Additive Regulations.
Connecting Module Couplings
Install each module according to its position number
indicated on its electrical distribution cabinet. Install
the primary module first. Each secondary module has
the same installation procedure as the previous
module.
1. Remove the coupling that attaches the headers to
the heat exchangers in order to position the header
with the next module and attach the header
coupling.
2. Remove all four small couplings to allow the main
headers to slide into the previous module.
3. Position each subsequent module approximately
16-inch from the previous module when positioning
the headers.

4. Lubricate the main header coupling gasket with an
approved lubricant and re-install onto the roll
grooved header pipe. Push the gasket flush with the
pipe end to avoid damage when installing the next
module.
5. Remove the small coupling that attaches the main
header to the heat exchanger.
6. After positioning the module, slide the header and
rotate it to avoid damage to the refrigeration piping.
7. Note the refrigeration pipe above the header. Note
the position of modules and headers extended.
8. Position each of the four headers and attach the roll
grooved couplings. Start by positioning the
lubricated gasket so that the gasket fits inside the
two grooves, one from each of the headers.
9. Loosen one side of the metal coupling and remove
the bolt from the other side to allow you to position
it over the gasket.
10. Install and tighten each of the four couplings. Begin
with the inside headers, then the outside headers.
Slide the module back to the previous module and
re-attach the header to the small coupling for the
heat exchanger.
11. Install the remaining modules using this procedure.
