Hoshizaki FM-1000AKE Installation Manual page 8

ENGLISH
* Pipes between the cooling tower and the icemaker should be
at least 20 mm DIA to reduce pressure loss, even though the
icemaker fittings are 13 mm DIA.
* Pressure loss in the water circuit inside the unit will be 5 to 6 m
when the cooling water flows at the ratio of 4 to 5 lit/min.
* Select a circulating pump referring to the above values of heat
flow.
[Icemaker Connections]
1) Attach the angled end of flexible inlet hose (accessory) to the
G3/4 fitting on the rear of the icemaker as indicated, ensuring
rubber sealing washer is correctly positioned. Hand tighten
sufficiently to provide leak free joint.
2) Attach the other end of inlet hose to the water tap, noting
washer is correctly positioned before hand tightening as above.
Note: If filtration or treatment is used, ensure icemaker section
only is on treated water supply, not the condenser.
3) Attach grey flexible outlet hose (accessory) to the R3/4 fitting
on the rear of the icemaker as indicated, confirming fitment of
rubber washer before finally hand tightening the joint. The hose
can be cut to length as necessary to suit position of main drain.
4) By means of a suitable spanner or wrench, tighten the 1/2-
3/4 and 3/8-3/4 nipples (accessory) into the Rc1/2 and Rc3/8
fittings on the rear of the icemaker as indicated. P.T.F.E. tape
and/or a suitable sealing compound should be used to obtain a
leak free joint.
Note: Jointing compounds should be approved and suitable for
potable water use.
5) Connect the condenser cooling circuit to the free end of 1/2-3/4
and 3/8-3/4 nipples as indicated using a suitable rigid type pipe.
[b] Connections according to regulations other than WRAS
by utilising accessory hoses
1) Follow the instructions from 1) to 4) in [a] above.
2) For condenser connections, use supplied accessory hoses and
make the same connections as 1) to 3) in [a] above to the free
end of 1/2-3/4 and 3/8-3/4 nipples as indicated.
