Rheem 018J*Z, Installation Instructions Manual

Page: 5 / 28

GENERAL
The information contained in this manual has been prepared to assist in the proper
installation, operation and maintenance of the air conditioning system. Improper
installation, or installation
not made in accordance with these instructions, can
result in unsatisfactory operation and/or dangerous conditions, and can cause the
related warranty not to apply.
Read this manual and any instructions packaged with separate equipment required
to make up the system prior to installation. Retain this manual for future reference.
To achieve optimum efficiency and capacity, the indoor cooling coils listed in the con-
densing unit specification sheet should be used.
APPLICATION
Before installing any air conditioning equipment, a duct analysis of the structure and
a heat gain calculation must be made. A heat gain calculation begins by measuring
all external surfaces and openings that gain heat from the surrounding air and
quantifying that heat gain. A heat gain calculation also calculates the extra heat
load caused by sunlight and by humidity removal.
There are several factors that the installers must consider:
• Outdoor unit location • Proper equipment evacuation
• System refrigerant charge • Indoor unit airflow
• Indoor unit blower speed • Supply and return air duct design and sizing
• System air balancing • Diffuser and return air grille location and sizing
CORROSIVE ENVIRONMENT
The metal parts of this unit may be subject to rust or deterioration if exposed to a
corrosive environment. This oxidation could shorten the equipment’s useful life.
Corrosive elements include, but are not limited to, salt spray, fog or mist in seacoast
areas, sulphur or chlorine from lawn watering systems, and various chemical conta-
minants from industries such as paper mills and petroleum refineries.
If the unit is to be installed in an area where contaminants are likely to be a prob-
lem, special attention should be given to the equipment location and exposure.
• Avoid having lawn sprinkler heads spray directly on the unit cabinet.
• In coastal areas, locate the unit on the side of the building away from the water-
front.
• Shielding provided by a fence or shrubs may give some protection, but cannot
violate minimum airflow and service access clearances.
• Elevating the unit off its slab or base enough to allow air circulation will help
avoid holding water against the basepan.
Regular maintenance will reduce the build-up of contaminants and help to protect
the unit’s finish.
