Installation, Operation and Service Instructions

SAFETY CONSIDERATIONS

The 90MA/MU Units are designed to provide safe and

reliable service when operated within design specifications.

However, due to system pressures, electrical components,

and equipment location, some aspects of installation,

operation and servicing of this equipment can be hazardous.

Only trained, qualified installers and service technicians

should install, operate, and service this equipment.

When working on the equipment, observe all precautions

on tags or labels attached to the unit. Safety notes in the

literature, and any other safety precautions that apply.

• Follow all safety codes.

• Wear safety glasses and work gloves.

• Use care in handling, rigging, and placing bulky

equipment.

WARNING

Never reach into unit while fan is running. Lock

open and tag power disconnect before working

on a fan. Remove the fuses and take them with

you after noting this on tag.

Check assembly and component weight to be

sure rigging equipment can handle them safely.

Note also any specific rigging instructions.

When steam cleaning coils, be sure area is

clear of personnel.

GENERAL

The 90MA/MU water cooled single-package cooling units

are designed to provide air conditioning aboard marine

vessels. The 90MA units are fitted with a water cooled

condenser and are factory charged, wired and piped. The

90MU units are similar to the 90MA except they are

configured for use of a remote mounted condenser.

An accessory discharge plenum may be installed to

provide free-blow into the conditioned space. Also, an

optional electric heater may be specified to provide comfort

heating.

INSTALLATION

Step 1 - Inspect Unit - Check unit against shipping order.

Inspect carefully for concealed shipping damage. If shipment

is damaged or incomplete, file claim with transportation

company and advise Carrier Transicold immediately.
