When received, the unit should be checked for damage that might have occurred in transit. If damage is
found it should be noted on the carrier’s Freight Bill. A request for inspection by carrier’s agent should
be made in writing at once. All our sales are FOB our warehouse in Fort Worth Texas and any in transit
damage is carrier responsibility.
Nameplate should be checked to ensure the correct model sizes and voltages have been received to
match the job requirements.
If repairs must be made to damaged goods, then the factory should be notified before any repair action
is taken in order to protect the warranty. Certain equipment alteration, repair, and manipulation of
equipment without the manufacturer’s consent may void the product warranty. Contact the MORTEX
MANUFACTURING Warranty Department for assistance with handling damaged goods, repairs, and
freight claims: (817) 624-0820 ext 225.
Note: Upon receipt check shipment for items that ship loose such as filters and remote sensors. Consult
order and shipment documentation to identify potential loose-shipped items. Loose-shipped items may
have been placed inside unit cabinet for security. Installers and owners should secure all doors with
locks or nuts and bolts to prevent unauthorized access
Thoroughly inspect all packages upon receipt of product. Ensure pallet(s) have not been dropped,
crushed or punctured. Inspect all contents for damage. If damage is found, immediately file a claim with
the delivering freight carrier

SAFETY
The installation and/or servicing of comfort conditioning equipment can be hazardous due to system
pressures and electrical devices.
ONLY TRAINED/QUALIFIED PERSONNEL SHOULD PERFORM SERVICE AND/OR INSTALLATION
OBSERVE ALL PRECAUTIONS AND WARNINGS IN PRODUCT DATA OR INSTRUCTIONS ON UNIT.
FOLLOW ALL SAFETY CODES.
Wear eye protection and gloves. Have a fire extinguisher readily available.
DISCONNECT ALL POWER SUPPLIES BEFORE REMOVING ANY PANELS.
DISCONNECTING MORE THAN ONE POWER SUPPLY MAY BE REQUIRED FOR SOME EQUIPMENT.
Locating the Unit
Placement of the unit relative to ductwork, electrical and plumbing must be carefully considered. Return
air plenum or duct can be mounted directly to the return air flanges. Use flexible gasket material to seal
the duct to the unit.
Verify floor, foundation or suspension support can support the total unit weight, including accessory
weights. Unit must be level in both horizontal axes to support the unit and reduce noise and vibration
from the unit.
Allow adequate service clearances as shown on the unit nameplate and unit drawing. Consult your local
building codes for additional service clearance requirements.
Allow adequate space for piping access and panel removal. Condenser water piping and condensate
drain connections are located on either side of the unit.
Suspended Units
Horizontal air handling units are equipped for suspended installations. The unit should be lifted into
position by supporting the unit with the skid used for shipping. The air handling unit must be installed
level and care should be taken to prevent damage to the cabinet. Other installation provisions may be
necessary according to job specifications.
LIFTING AND HANDLIND THE UNIT
Horizontal, Vertical and Modular Units have channels underneath the base which provide lifting access
to the underside of the unit and allow moving without physical damage.
Before lifting the unit, be sure that all the shipping materials has been removed.
Incorrect lifting can cause damage to the unit, injury or death. Lifting equipment capacity should exceed
unit weight by an adequate safety factor. Always test lift unit not more than 24 inches to verify the
proper center of gravity lift point.
