Hoshizaki KM-1300SAH-E, KM-1300SRH-E installation manual English, c INSTALLATION

ENGLISH

•Preferably a dry and well ventilated area with 60 cm clearance on both front and rear for ease of mainte- nance and service should they be required.

•Normal condenser ambient temperature: -28°C to +50°C. Temperatures not within this operating range may affect the production capacity of the icemaker.

•The maximum line length for the standard refrigerant charge is 20 meters.

•The absolute maximum line length is 30 meters and will require an additional refrigerant charge. Please contact your nearest Hoshizaki office listed in the Instruction Manual for guidance.

•The Condenser should not be installed more than 10 meters above the height of the icemaker or more than 3 meters below it measured from fitting to fitting.

Note: If the recommended guidelines of the installation are exceeded, the icemaker performance may be reduced.

[c] INSTALLATION

1)Secure the Legs to the condenser unit with eight M8 x 16 mm. Hexagon Bolts and M8 Nuts as shown in the illustration. See Fig. 7.

Note: Locate the Legs symmetrically.

Fig. 7

2)Eight mounting holes are provided to secure the Condenser to the site surface (bolts not supplied).

3)Install enough length of the two copper tubings between the icemaker and condenser unit. Pre- charged tubes have fitted Aeroquip couplings. Avoid excess loops or coils to eliminate oil traps or crimps in the tubing. Both tubes should always be sepa- rately insulated. See Fig. 8.

•A connector kit “OS-QUICK” is available for field- fabricated lines from HOSHIZAKI EUROPE.

•R-404A precharged tubing kits, available as optional equipment also from HOSHIZAKI EUROPE, are recommended.

4)Line sets fabricated in the field should be leak tested and evacuated before connection to the icemaker/ condenser through the charging ports on the Aeroquip couplings and charged with R-404A refrig- erant vapor to a pressure of 15-30 PSIG (1-2 bar).

Note: Factory fabricated tubing kits are precharged and do not need to be evacuated.

5)Remove the plastic caps protecting the couplings. Lubricate the coupling threads and O-rings with clean refrigerant oil of a type suitable for R404A.

6)Connect and tighten the couplings onto the icemaker and Condenser as follows until they bottom out and then a further 1/4 turn to ensure a good brass-to- brass contact.

Icemaker discharge refrigerant line:

1/2" OD tubing to “DIS” of condenser unit Icemaker liquid refrigerant line:

3/8" OD tubing to “LIQ” of condenser unit
