plumbing help for VarioS-4 return pump on Reefer 170

[SFREEF3R]

I could use some help finding simplest way to attach this return.

The Reefer 170 return line is a 5/8" ID tube (*I think*)

The VarioS 4 has a few different options a 1" slip PVC fitting and an 1" barb fitting (which can be reduced to 3/4" barb)

Trying to find the simplest/cleanest way to do this. Any help would be appreciated from those of you with more plumbing experience.

Are you trying to decide if you want to hard-pipe or soft-pipe the VarioS4?

I’m want to use the 5/8” tube but trying to find the most efficient way to connect. At this point I’m thinking of using the 1” Slip union supplied with the Varios and connecting it to a 1” spigot x 3/4” FPT fitting. I can then get a 5/8” barb X 3/4” MPT fitting to connect to that.

3/4" NPT x 5/8" Barbed Straight Reducing Fitting - Indelco
1" Spigot x 3/4 FPT

attaching to the in box union - looks something like this (but I think the threads on the pump are metric):

Schedule 80 Union Slip x Thread

Why does BRS recommend this? We have never heard “I put too many unions on my plumbing.” When it comes to the initial plumbing, servicing, repair, or replacement of any hardware unions will be your best friend. For a couple extra bucks right off the start, down the line they will pay for...
