Warning, Caution and Important notes appear throughout
this manual in specific and appropriate locations to alert In-
stalling Contractors and maintenance or service personnel
of potential safety hazards, possible equipment damage or
to alert personnel of special procedures or instructions that
must be followed as outlined below.
Hazards may exist within this equipment because it con-
tains electrical and numerous moving components. Only
qualified service personnel should install or service this
equipment. Untrained personnel may perform basic main-
tenance such as maintaining filters. Observe precautions
marked in literature and on labels attached to the unit. Fol-
low all safety codes.
These ventilators can provide 100% outdoor air ventila-
tion or, depending on options selected, varying amounts of
recirculation between the exhaust and supply airstreams.
The VHCs use an enthalpy wheel for total energy recov-
ery which provides superior efficiency in hot and humid
climates. These models are also effective in cold climates
and use various types of frost control or defrost to ensure
proper operation when the outside temperatures are ex-
tremely low. Units intended for rooftop installations must
be installed on a factory or field supplied roofcurb. This
manual contains information on optional components that
may or may not be included with this unit. Refer to the sub-
mittals for options that pertain to this unit.
Using Mammoth units for temporary ventilation during
construction constitutes a violation of Mammoth warranty
terms which indicate that the unit warranty would be void
“…if equipment is misapplied or if any alterations are made
to the basic design or operating requirements as listed
on the original order and shipped from the factory unless
approval is received in writing from Mammoth” Fine dust,
larger particulate matter, solvents, varnishes and other
chemicals may cause filter clogging and elevated cabinet
pressures, higher power consumption and possible ir-
reparable damage to the desiccant material of the enthalpy
wheel, which could reduce energy recovery performance of
the wheel and also reduce the heat transfer effectiveness
of other components. Potential damages include, but are
not limited to, these examples.
Consult local building codes and electrical codes for spe-
cial installation requirements and note additional require-
ments listed in this manual. In choosing the installation
location of the unit, consider the following factors:
• The unit should be installed to allow easy access for
maintenance and for systems operation. See the ser-
vice clearance dimensions in Appendix A .
• When possible, mount the unit over an unused area
such as a hallway. Although fans and motors are
mounted on vibration isolators or are dynamically
CAUTION

WARNING
Mammoth equipment is not designed to be used for tempo-
rary heating, cooling and/or ventilation during construction.
