Prepare the closet ductwork for later connection
to the case. The collar on top of the case accepts
standard 10" duct. Pull all duct tight. Extra duct
slack can greatly increase static pressure.
CAUTION:
cause airflow restrictions. Do not use flex duct for 90°
bends or unsupported runs of 5 ft. or more.
Size the duct for the CFM based on the specific
combination of ZVAC model and Hydronic Kit model
as shown in the table below. Ensure that the total
external static pressure of the ducting does not
exceed .25" w.c., gauge, when flowing the stated
CFM. Sizing the duct in this way will ensure correct
operation and full heating capacity at high speed,
and proper operation at any reduced speed, if
alternatively selected.
Consult an HVAC engineer for proper application if
necessary. Once the unit is installed and configured,
the external static pressure (ESP) can be checked
(measured) with a manometer or pitot tube, with
the fan set to "High CFM" to make sure it does not
exceed .25" w.c. Once verified, change the fan
speeds for heating and cooling mode to the desired
setting.

For heating and cooling operation, higher CFMs will
maximize the heating or cooling output of the ZVAC,
enhance room circulation and increase duct noise.
Lower CFMs will reduce heating or cooling output,
but provide better dehumidification in cooling mode.

Cut off a suitable length of the supplied tubing
insulation. Slit it along its length and then press it into
the area between the tube and the casing hole to seal
potential air leakage.
Connect to building hot water supply. Insulate hot
water tubing as required.

Verify the actuator switch is NOT LOCKED
in the OPEN position.
NOTE: The valve can be manually operated
by pushing the actuator switch slowly to the OPEN
position. Push down to lock. If the actuator is not
locked, it will return automatically to the closed
position very slowly.
