Unit Installation
1. Units should be mounted on a vibration-absorbing pad slightly
larger than the base of the unit. See Table 6.1 below for
Modine vibration pad part numbers. If the unit isn’t mounted
on a vibration-absorbing pad, it must be raised off the floor
to prevent damage due to accidental flooding. It is not
necessary to anchor the unit to the floor.
2. Check to ensure that the unit is level in both directions and
also plumb. If adjustment is necessary, Modine recommends
the placement of metal shims in the outermost corners of the
base.
3. Provide adequate clearance for all access panels.
4. Provide easy access for servicing water valves, fittings and
compressor.
5. Provide access to the controller and all electrical connections.
6. Provide a clear physical path to the unit. Adequate space
should be provided to allow removal of the unit, if necessary.
Water Connections
1. All units utilize swivel pipe fittings for water connections that
are rated for 150 psi.
2. The connections have a rubber gasket seal similar to a garden
hose gasket, which, when mated to the flush end of most 1"

threaded male pipe fittings (MPT), provides a leak-free seal
without the need for thread sealing tape or joint compound.
3. The water piping system should include pressure/temperature
taps for serviceability.
4. Refer to Figure 6.1. Install the brass spacer and rubber gasket in
swivel connector prior to attempting any connection (rubber
gasket and brass spacer kits are shipped with unit). To make
the connection, mate the field supplied male pipe thread fitting
against the rubber gasket in the swivel connector and thread
the female locking ring onto the pipe threads, while
maintaining the brass elbow in the desired direction. Tighten
the connectors by hand, and then gently snug the fitting with
pliers to provide a leak-proof joint.
5.
DO NOT OVERTIGHTEN
, as leaks may occur.
6.
NOTE:
Never use flexible hose smaller than 1" inside
diameter on the unit. Limit the length to 10' per connection in
one direction. Check carefully for leaks.
Installation with Existing Air Handler or
Refrigerant Coil
Modine recommends installing Split units with a new matching
Modine Air Handling or A-coil unit, but the Split unit may be
matched with an existing air handler or coil if the following
conditions are met:
1. Coil must be R-410A rated and use a heat pump thermal
expansion valve with internal check valve.
2. The air coil and line set have been flushed with a compound
that vaporizes in accordance with the instructions provided
with the flushing agent.
Follow the air handler manufacturer’s installation instructions to
install the air handler. Note that such installations do not qualify
for Energy Star.
