Any service work requiring removal or adjustment
in the fan and/or motor area will require that the
dimensions below be checked and blade adjusted in or
out on the motor shaft accordingly.

1. Caution homeowner to maintain clean air filters at
all times. Also, not to needlessly close off supply
and return air registers. This reduces airflow
through the system which shortens equipment
service life as well as increasing operating costs.
through the system which shortens equipment
service life as well as increasing operating costs.
2. Check all power fuses or circuit breakers to be sure
that they are the correct rating.
3. Periodic cleaning of the outdoor coil to permit full
and unrestricted airflow circulation is essential.
Pressure serVIce POrts
High and low pressure service ports are installed on
all units so that the system operating pressures can be
observed. Pressure tables can be found later in this
manual covering all models on cooling cycle. It is
imperative to match the correct pressure table to the
unit by model number.

specific situations can affect the pressure readings,
this information should only be used by certified
technicians as a guide for evaluating proper system

1 Motor will deliver consistent CFM through voltage supply range with no deterioration
(197-253V for all 230/208V models).
2 Continuous CFM is the total air being circulated during continuous (manual fan) mode.
3 Will occur automatically with a call for “Y” for cooling mode operation.
4 Will occur automatically with a call for “W1” for heating mode operation.
