MANUAL- I/O SELF-CONTAINED FNGSC-A

WARNINGS:

If the information in these instructions are not followed

exactly, a ﬁre or explosion may result, causing property

damage, personal injury or death.

Installation and service must be performed by a qualiﬁed

installer or service agency.

READ THE ENTIRE MANUAL BEFORE

INSTALLING OR USING THIS EQUIPMENT.

The unit uses R-290 gas as the refrigerant. R-290 is

ﬂammable and heavier than air. It collects ﬁrst in low

areas but can be circulated by the fans. If propane gas

is present or even suspected, do not allow untrained

personnel to attempt to ﬁnd the cause. The propane

gas used in the unit has no odor. The lack of smell does

not indicate a lack of escaped gas. If a leak is detected,

immediately evacuate all persons from the store, and

contact the local ﬁre department to advise them that

a propane leak has occurred. Do not let any persons

back into the store until the qualiﬁed service technician

has arrived and that technician advises that it is safe to

return to the store. No open ﬂames, cigarettes or other

possible sources of ignition should be used inside or in

the vicinity of the units.

FAILURE TO ABIDE BY THIS WARNING COULD

RESULT IN AN EXPLOSION, DEATH, INJURY AND

PROPERTY DAMAGE.

IMPORTANT

Keep in store for future reference!

What to do if my Hussmann Merchandiser compressor will not start and cuts out on overload?

  Wendy RushAug 12, 2025
  If your Hussmann Merchandiser compressor won't start and cuts out on overload, there could be several reasons. First, ensure the cabinet voltage isn't more than 5% below the rating. Other potential causes include a defective compressor or relay (in which case, consider replacing them). Also, check for restrictions like a pinched cap tube (repair or replace if needed) or moisture (leak check, replace drier, evacuate and recharge). A blocked condenser due to dust and dirt can also cause this issue, so clean the condenser. Finally, a defective condenser fan motor could be the culprit, so consider replacing it.

How to fix warm storage temperature in Hussmann Merchandiser?
- M
  Melinda PhillipsAug 16, 2025
  If you're experiencing a warm storage temperature in your Hussmann Merchandiser, start by resetting the temperature control, rotating the knob clockwise. A short of refrigerant could also be the cause, requiring a leak check, replacement of the drier, evacuation, and recharge. The cabinet location might be too warm, so move it to a cooler spot or address any excessive heat sources. An overcharge of refrigerant could be the problem; in this case, purge the system, evacuate, and recharge. Lastly, low voltage causing the compressor to cycle on overload can lead to this issue, so ensure the compressor voltage isn't more than 5% below the rating.
