Air-Cooled Machines
Air-cooled machines require a minimum of 3 in. (76 mm)
of air space on both sides, 3 in. (76 mm) at the rear, and
12 in. (305 mm) on the top of the machine. Minimum air
clearances must be met to assure adequate air flow for
optimum performance.
Water-Cooled Refrigeration Machines
On the back of the machine, two additional 3/8 in. (9.5
mm) F.P.T. water connections for condenser inlet and
outlet have been provided for easy hook-up. A 3/8 in.

(9.5 mm) inside diameter water lines should be
connected to the machine. Flexible lines are
recommended, if local codes permit. Failure to use
adequate size water lines may cause the machine to go
on high head pressure and shut down.
Depending on local water conditions, it may be advisable
to install a water strainer to prevent foreign substances
from clogging the automatic water valve.
Do not install a hand shutoff valve on the out line.
Water-cooled machines are counter flow, and the water
should flow in this order: first, through the automatic
water valve; second, through the inlet located at the
bottom of the condenser; and third, through the outlet
fitting located at the top of the condenser to an open trap
drain.
Important! Water pressures are pre-set at the factory.
Do not adjust the water pressure. Improper water

adjustments may cause operation discrepancies.
Water Connections
An adequate cold water supply must be provided with a
hand shutoff valve. On the back of the machine, a 3/8 in.
(9.5 mm) MFL water connection has been provided for
easy hook-up. A flexible line is recommended, if local
codes permit. A minimum of 25 psi (172 kPa) water
pressure is required to avoid having the machine cut out
the low water pressure switch. A booster pump must be
provided if this pressure is not available.
Note: Water lines beyond 200 ft. (61 m) require 1/2 in.
(13 mm) water lines.
IMPORTANT! A backflow prevention device is
required on the incoming water connection side. Please
see the applicable national, state, and local codes for
determining the proper configuration.
It is always a good practice to have a filter system to
improve the quality of the water and to avoid clogging the
operating components.
Important! The water filter (064422-SER) must be
thoroughly flushed with water before connecting it to the
machine.
This removes any loose particles present from the
manufacture of the filter that could clog the flow
control.
1. To flush the filter, connect the inlet end of the filter to
the water supply.
2. Position the outlet end of the filter over an empty pail.
3. Open the water supply. Allow water to flow through
the filter until the water exiting the filter is clear.
4. Close the water supply.
5. Attach the outlet end of the filter to the machine.
Reopen the water supply.
