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. (Note: the bracket is stored in the condenser
air compartment. Remove them before replacing the side screen). 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.
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
obstructions.
D)
When installing multiple units, please note the recommended clearances noted in
Table 4.
4. Airflow Requirements:
Note the minimum CFM requirements (Table 6). 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. Marvair
®
strongly recommends referring to the current edition of
the National Fire Protection Association Standards 90A and 90B before designing and
installing duct work. The duct system must be engineered to insure sufficient air flow
through the unit to prevent over-heating of the heater element. This includes proper
supply duct sizing, sufficient quantity of supply registers, and adequate return and filter
areas. Duct work must be of correct material and must be properly insulated. Duct work
