RJ SERIES INSTALLATION MANUAL
MovingandStorage
Move units in the normal “up” orientation. Horizontal units may be moved and stored per the information on the packaging. Do not stack
more than three units in total height. Vertical units may be stored one upon another to a maximum height of two units. Do not attempt to
move units while stacked. When the equipment is received, all items should be carefully checked against the bill of lading to be sure all
crates and cartons have been received. Examine units for shipping damage, removing the units from the packaging if necessary. Units in
question should also be internally inspected. If any damage is noted, the carrier should make the proper notation on the delivery receipt,
acknowledging the damage.
UnitLocation
Locate the unit in an indoor area that allows for easy removal of the filter and access panels. Location should have enough space for
service personnel to perform maintenance or repair. Provide sufficient room to make water, electrical and duct connection(s). If the unit
is located in a confined space, such as a closet, provisions must be made for return air to freely enter the space by means of a louvered
door, etc. Any access panel screws that would be difficult to remove after the unit is installed should be removed prior to setting the unit.
On horizontal units, allow adequate room below the unit for a condensate drain trap and do not locate the unit above supply piping. Care
shouldbetakenwhenunitsarelocatedinunconditionedspacestopreventdamagefromfrozenwaterlinesandexcessiveheat
thatcoulddamageelectricalcomponents.
InstallingVerticalUnits
Prior to setting the unit in place, remove and discard the compressor hold down shipping bolt
located at the front of the compressor mounting bracket.
Vertical units are available in left or right air return configurations. Top or rear flow vertical units
should be mounted level on a vibration absorbing pad slightly larger than the base to provide
isolation between the unit and the floor. It is not necessary to anchor the unit to the floor (see
right).
Bottom flow units should be mounted level and sealed well to floor to prevent air leakage.
Bottom flow units require the supply air opening to be cut at least 1/2˝ larger than the unit’s air
outlet. Protect the edges of combustible flooring with sheet metal over-wrap or other non-
combustible material.
WARNING:Beforeperformingserviceormaintenanceoperationsonasystem,turnoffmainpowerswitchestothe
indoorunit.Ifapplicable,turnofftheaccessoryheaterpowerswitch.Electricalshockcouldcausepersonalinjury.
Installing and servicing heating and air conditioning equipment can be hazardous due to system pressure and electrical components. Only
trained and qualified service personnel should install, repair or service heating and air conditioning equipment. Untrained personnel can
perform the basic maintenance functions of cleaning coils and cleaning and replacing filters. All other operations should be performed by
trained service personnel. When working on heating and air conditioning equipment, observe precautions in the literature, tags and labels
attached to the unit and other safety precautions that may apply.
Follow all safety codes. Wear safety glasses and work gloves. Use a quenching cloth for brazing operations and have a fire extinguisher
available.
