MOST COMMON INSTALLATION MISTAKES

Pay attention - don’t make these common installation mistakes.

Mistakes marked (1) will destroy your system.

Mistakes marked (2) will make your system always function poorly.

Mistakes marked (3) will make your system maintenance frequent and/or problematic.

Component Locating Mistakes

● Mounting the condensing unit in such a tight space that there is no room for service

access. (3)

● Mounting condensing unit in an area that is too hot or has too little ventilation. (2)

● Mounting the water pump on a resonating platform. (2)

● Failure to mount freezer plates such that no point in the box is greater than 18" away from

the plate. (2)

Tubing Run Mistakes

● Incorrectly routing the suction (return) line and connecting the “T’s” so that oil

traps are created. (1)

● Using high-temperature braze (“Silfoss” or “Phosbronze”) rather than Stay-Brite #8.

solder to make the tubing connections. (2,3)

● Failure to allow sufficient room on the suction tubing to properly mount the expansion

valve sensing bulbs. (2)

● Improperly positioning and/or insufficiently tightening the expansion valve sensing bulbs.

● Overheating joints and using too much solder or flux. (2)

● Using “flare” fittings instead of soldered connections. (3)

Electrical Connection Mistakes

● Making poor quality connections when lengthening the temperature probe wires. (2)

● Failure to connect the “Engine Start Input” wire on ECM control installations. (2)

● Failure to run the wire between thermostatic/ECM controls on multi-zone systems. (2)

● Failure to properly crimp ring terminals. (2,3)

System Startup Mistakes

● Opening the Rotalock valves on the condensing unit before the rest of the tubing has

been properly leak checked and evacuated. (2,3)

● Failure to understand Glacier Bay’s sequential box pull-down (freezer first, then

refrigerator, etc) and thinking there is a problem because “the freezer is cooling but the

refrigerator isn’t”.
