higher water temperature will increase
system capacity, and the anti-scald valve will
reduce the risk of scalding. Since some
areas have specific regulations regarding
combo systems, check your local building
code for details on water tank temperatures,
tempering valves, and pump timers. cooling coil capacities
Possible cooling coil capacities are given in
the Table 1.
INSTALLATION .
The installer must adhere strictly to all local
and national code requirements pertaining to
the installation of this equipment.
Detailed instructions are shipped with all
accessory items and should also be followed
in detail.
air handler mounting
The MaxAir(e)
™ combo air handler can be
installed in most configurations. Some
precautions must be observed for some of
the possible mounting positions.
For installations where the access door faces
up or down ensure the external circulating
pump is not mounted with its shaft in the
vertical position. The pump shaft must be
mounted horizontally to avoid damage during
operation.
The air handler can be mounted by securing
straps through any of the existing screw
holes in the cabinet. Should the existing
screw be too short for securing a mounting
strap, a longer screw can be used provided
care is taken not to damage any internal
components.
When fastening straps using screws, special
care should be taken in the vicinity of the coil
to avoid tube puncture.
The cabinet is designed so that the return air
can be located on either side of the cabinet,
through the bottom of the cabinet, or from the
back. Position the filter rack so that the filter
is readily accessible.
Install the air handler with the door firmly
screwed in place to make certain the cabinet
is mounted without racking. Provide at least
24 inches of service access clearance in
front of the access panel of the air handler.
zero clearance is acceptable on all other
faces.
domestic water piping
Install a
½
” (12mm) sediment faucet for use
as a drain/purge valve. The drain valve must
be located downstream of the pump and
check valve, and upstream of the isolation
valve (if isolation valve is present). This
arrangement will allow any air trapped in the
system to be easily flushed out. Follow the
instructions in the
Start-up & Troubleshooting
sections.
Isolation valves are recommended, but not
required. Installing isolation valves facilitates
easy servicing and ensures positive purging
of the system during start-up.
The isolation valves, if installed in the system
should not be used as a throttling valve.
All joints in copper pipe must be lead free
solder. All piping must be suitable for potable
water use. All pipe & pipe connections shall
comply with local building codes.
When soldering, special care should be
taken to not overheat the water connections
on the unit. Use a wet rag or heat absorption
compound to prevent excessive heat buildup.
Maximum pipe lengths for all MaxAir(e)
™
combo air handlers can be calculated using
the information in the Design Manual.
When both top and side connections are
provided on the water heater,
