INSTALLATION GUIDELINES
Unpacking
Verify that all required parts and the correct quantity of each item have been received. If any items are missing, report shortages to your local
representative to arrange for obtaining missing parts. Confirmation of shipment(s) must be limited to only items on the bill of lading.
Storage
Units are protected against damage during shipment. If the unit cannot be installed and operated immediately, precautions need to be taken
to prevent deterioration of the unit during storage.
The customer assumes responsibility of the unit and accessories while in storage. The manufacturer will not be responsible for damage
during storage. These suggestions are provided solely as a convenience to the customer.
The ideal environment for the storage of units and accessories is indoors, above grade, in a low humidity atmosphere which is sealed to
prevent the entry of blowing dust, rain, or snow. Units designed for outdoor applications may be stored outdoors.
Indoor
Maintain temperatures evenly to prevent condensation. Remove any accumulations of dirt, water, ice, or snow and wipe dry before moving
to indoor storage. To avoid condensation, allow cold parts to reach room temperature. Leave coverings loose to permit air circulation and to
allow for periodic inspection.
The unit must be stored at least 3½ in. (89 mm) off the floor. Clearance must be provided to permit air circulation and space for
inspection.
Outdoor
The unit must be placed on a level surface to prevent water from leaking into the unit. The unit should be elevated so that it is above water
and snow levels.
Ensure sufficient support to prevent unit from settling into soft ground. Locate parts far enough apart to permit air circulation, sunlight, and
space for periodic inspection. To minimize water accumulation, place all unit parts on blocking supports so that rain water will run off.
Do not cover parts with plastic film or tarps as these cause condensation of moisture from the air passing through heating and cooling
cycles.
Inspection and Maintenance
While in storage, inspect units once per month. Keep a record of inspection and maintenance performed.
If moisture or dirt accumulations are found on parts, the source should be located and eliminated. At each inspection. If paint deterioration
begins, consideration should be given to touch-up or repainting.
Machined parts coated with rust preventive should be restored to good condition promptly if signs of rust occur. Immediately remove the
original rust preventive coating with petroleum solvent and clean with lint-free cloths. Polish any remaining rust from surface with crocus cloth
or fine emery paper and oil.
Do not destroy the continuity of the surfaces.
