SECTION 1 – INTRODUCTION
The ParaFlow™ unit makes very little noise or vibra-
tion (See Typical Noise and Vibration Levels section);
therefore, vi bra tion elim i nat ing mounts are gen er al ly
not re quired. How ev er, when the unit is in stalled in
an area where even mild noise would be a prob lem,
such as on a floor near a con fer ence room, sleep ing
area or roof, where there are very strict noise and sound
re quire ments, seek the advice of an acous ti cal con sult
ant.
Check the type of fuel to be used when selecting the in-
stal la tion site. Gas allows more flexibility in site se lec-
tion than does oil. Standard oil units require gas supply
for burner pilot ignition. Also, a means of metering gas
flow must be provided.
A minimum of 42 inches of service space is rec om-
mend ed along each side of the unit. Tube pull space
equivalent to one unit length must be provided on at
least one end of the main unit shell. The end opposite
the tube pull end should be allowed 60 inches of ser-
vice clear ance. Refer to Appendix A, Unit Weights and
Dimensions for specific Unit Clearance Data.

Leave at least 20 inches of space above
the unit and at least 40 inches above the
first-stage generator.
ParaFlow™ chillers are not suitable for outdoor
in stal la tion. They must NOT be stored in tem per-
a tures below 35°F. The machine room must be en-
closed, well-lighted and properly ventilated to keep
its temperature no higher than 104°F and no lower
than 35°F. Relative humidity in the machine room
must never reach the sat u ra tion point. Condensation of
moisture may cause cor ro sion and damage to electrical
components.
All local utility codes vary with location. Be sure to
check and comply with them when installing the unit.
