3. Check for appropriate ventilation at the rear of the cooling unit. If the space is
too small or restricted for the hot air exhaust to dissipate, you may need to
add a rear duct retrofit kit to separate the hot air exhaust and the fresh air
intake.
4. Check for any obstructions to the intake and exhaust at the rear of the cooling
unit. If you are ducting the rear of the cooling unit, you must use an auxiliary
fan, and you cannot have reducers in the ducting.
5. If the rear of the unit is recessed in the wall, make sure to separate the
exhaust from the intake with an insulated board. Depending on the length of
the recessed space and the cooling unit, you may need to add auxiliary fan
support to overcome the static pressure that occurs from the restricted space.
6. If you have a grill or vent cover where the hot airflow terminates, they may be
too restrictive for the cooling unit. To test, remove the duct covers and see if
the problem is resolved. If so, you will need to replace with less restrictive duct
covers.
If the rear of the unit is ducted:
-
The auxiliary fan MUST be operating when the cooling unit is cycling
-
The fan should be facing towards the cooling unit if installed on the intake
side or way from the cooling unit (preferred) if installed on the exhaust side
-
The ducting must be 6" diameter (or equivalent) from start to finish (ie no
reducers)
If these actions do not resolve the issue, we will be glad to further assist you. In
order to troubleshoot, start with the unit "Off" for 10 minutes, then gather the
following information:
-
Please send pictures of the installation, front and rear, to
with the pictures attached. We need 4 pictures: a closeup of the entire unit
AND a picture showing the unit in the installed environment for both the front
and the rear of the cooling unit.
-
If the hot side of the unit is ducted, let us know if the exhaust and intake
come from different spaces. If so, let us know how big is the space where
you're ducting from and to
