2.3 INSTALLATION
Typical Remote Pump Installation
The hopper mix pump is completely installed on the
freezer. The remote mix pump is designed for mounting
in a walk-in cooler. Select a location that is close to the
soft serve freezer and a grounded 115 volt (220 volt if
50 hertz) receptacle. The mix pump should not be
located near heavy traffic or in a congested area. Refer
to Figure 2 and the following steps:
REMOTE MODELS INSTALLATION
A. Install the mix pump in an upright position on the
wall. Allow clearance for a mix can under pump.
Mount by bolting bracket to wall using 1/4 inch
(64cm) diameter lag bolts of sufficient length to hold
securely.
B. Connect 5/8 inch (1.60 cm) I.D. plastic food grade
tubing between pump cylinder (inlet) and mix
container.
C. Connect 1/2 inch (1.27 cm) plastic food grade tubing
between pump body mix transfer tube (outlet) and
refrigerated mix transfer line. Secure with No. 26
hose clamp or equivalent.
D. Connect 1/2 inch (1.27 cm) plastic food grade tubing
between safety relief fitting to a separate pail or shot
can.
NOTE
This line allows mix to escape if the system
pressure should exceed 30 P.S.I.
E. Plug mix pump into a 115 volt grounded receptacle.
(Customer must provide plug for 220 volt, 50 hertz
remote pump.)
WARNING
TO MINIMIZE SHOCK HAZARD, THE REMOTE
MIX PUMP MUST BE PLUGGED INT O A
PROPERLY GROUNDED ELECTRICAL
RECEPTACLE WITHOUT THE USE OF A
GROUND ADAPTER PLUG.
2.4 MIX PUMP CHECK OUT
The mix pump has been thoroughly cleaned and properly
lubricated at the factory. Before using, the mix pump
should be disassembled. This is necessary to remove
any foreign materials and to familiarize operators with
the correct assembly procedures.
A. The over-run adjustment is preset at the factory . If
an adjustment becomes necessary, refer to Section
4.1.
B. The pump pressure is preset at the factory. If an
adjustment becomes necessary, refer to Section 4.2.
C. On remote pumps, check for air leaks by placing
the suction line into three gallons of cold water. Place
the freezer switches in the OFF position. Close the
spigot and freezer air vents. Place mix pump switch
in the ON position and allow the system pressure to
build up and pump to shut OFF automatically. Leave
pump on for ten minutes. During this time do not
open spigot or freezer air vent s. If pump does not
automatically start again during this period, the
system is free of leaks. If the pump does start, there
is a leak in the system. Locate leak by applying a
liquid detergent or bubbles solution with a small
brush to all tubing connections and “O”-ring seals.
Correct as required.
