HEAT EXHAUST CONNECTION NOTES
1. VENT LINE -
The exhaust vent line required for MOJAVE systems using
the Heat Exchanger and systems with the Heat Exchanger removed
have different requirements.
Use metal pipe on systems without a Heat Exchanger while PVC
Schedule 40 pipe can be used on systems with a Heat Exchanger.
Do not make a trap in the exhaust vent piping. Do not use 90
ο fittings.
Also see Exhaust Vent Protection and Ventilation Requirements below.
2. V3, V5 & V7 PUMP EXHAUST VENT CONNECTION -
Connection between
the pump and exhaust vent piping is typically made via the supplied 2-inch
Black Flex tubing.
3. EXHAUST VENT ASSEMBLY -
The supplied assembly must be
installed at the
lower end of the vent pipe to collect condensation
produced during pump operation. The
bottom of the Y connector
should be located 18 inches from floor. Attach the drain tube to the drip
leg quick-connect fitting to allow drainage into floor drain/sink.

Exhaust Vent Protection.
If the exhaust piping is venting to the outside of the building, precautions must be taken to protect
the equipment room from weather elements and animal intrusion. This can be accomplished by
using one of the three methods shown on the right.

Exhaust Vent Requirements.
The MOJAVE equipment must be used in a controlled-temperature environment. Maintain
equipment room temperature between 40 and 105 degrees Fahrenheit. An exhaust fan is
necessary if room temperature is not maintained by other methods.
Adequate forced ventilation must be provided across the unit by placing an appropriate
exhaust fan opposite an equivalent air intake vent . The fan should be placed higher than the
associated intake vent. Recommended minimum exhaust fan requirements for each MOJAVE
unit are listed to the right.
Note:
Only 1 pump is running when operating in idle mode.
