Apply insulation
All evaporator parts are factory insulated on the shell surfaces, end sheets, liquid feed line to flow
chamber, compressor suction connection, and evaporator liquid heads and water connection
nozzles.
All facility chilled water piping surfaces must be insulated to prevent condensation from causing
any type of operational heat loss or component damage on all piping upstream and downstream of
the chilled water evaporator waterbox nozzles. Johnson Controls do not insulate the facility chilled
water piping surfaces.
Verifying OptiView panel condensate hose routing
The YVAM chiller OptiView control panel uses a cooler to maintain optimum internal temperatures.
This cooler may generate condensate and has a condensate hose that
must
be routed external to
the control panel before operation. This prevents any moisture buildup within the control panel.
1. At installation, locate the condensate hose inside the OptiView control panel.
2. Uncoil the hose and connect it to the rear of the OptiView panel cooler condensate barb fitting.
3. Route and secure the hose on the chiller so that condensate can drip at a preferred location,
with the tube termination pointing toward the bottom of the unit. See the following figure.

Unit heater operation verification
The YVAM chiller uses various heaters to protect all of the devices that are susceptible to low
ambient temperature limits. As part of the commissioning process of the chiller, verify the
operation of these heaters to ensure reliability of the various components. Log the verification
of heater operation using the current values for each heater in
Form 160.88-CL2
during chiller
commissioning. Refer to the
Maintenance
section in
Form 160.88-OM1
for the instructions to test
each device.
WARNING
All appropriate electrical safety measures must be followed when testing these heaters because these
circuits will be energized.
