Failure to observe and follow Warnings and Cautions and these Instructions could result

in death, bodily injury or property damage. Read this manual and follow its instructions

and adhere to all Cautions and Warnings in the manual and on the Marvair unit.

2.1

Equipment Inspection

Concealed Damage

Inspect all cartons and packages upon receipt for damage in transit Remove cartons and check for

concealed damage. Important: keep the unit upright at all times. Remove access panels and examine

component parts. Inspect refrigerant circuit for fractures or breaks. The presence of refrigerant oil

usually indicates a rupture. If damage is apparent, immediately file a claim with the freight carrier.

Units that have been turned on their sides or tops may have concealed damage to compressor motor

mounts or to the oil system. If the unit is not upright, immediately file a claim for concealed damages

and follow these steps:

1. Set unit upright and allow to stand for 24 hours with primary power turned on.

2. Attempt to start the compressor after 24 hours.

3. If the compressor will not start, makes excessive noise, or will not pump, return the unit to the

freight carrier.

2.2

Installation Requirements

General

1. Inspect unit for completeness. Check for missing parts (e.g. hardware). Refer to the installation

kit information in section 2.3.

2. Remove access panels and check for loose wires. Tighten screw connections.

3. Complete and mail the warranty registration card.

You must consider all of the following when choosing the installation site:

1. Noise. Install the unit so that the least amount of noise will be transmitted to inhabited spaces.

2. Condensate Drainage. Condensate produced during operation must be discharged to a suitable

drain.

3. Placement.

A) Place the unit in a shaded area, if possible.

B) Install it above ground for protection against flooding.

C) The unit exhausts air. Be sure that the airflow is not impeded by shrubbery or other obstruc-

tions.

D) When installing multiple units, please note the recommended clearances noted in Table 4.

4. Airflow Requirements:

The maximum static pressure for the ECUA90 is 1.60 IWG (400 Pa) and 2.20 IWG (550 Pa) for

the ECUA120. Keep duct lengths as short as possible. Do not obstruct airflow through the unit.

Duct work should be designed and installed in accordance with all applicable safety codes and

standards. Industrial Climate Engineering strongly recommends referring to the current edition of

the National Fire Protection Association Standards 90A and 90B before designing and installing duct
