Only after the above steps have been completed should
the water piping be connected to the chiller/heater.
Dowfrost
Important:
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
master module first. Each slave 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 rolled
groove 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 rolled
groove 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.
