3.8 FILLING THE OIL RESERVOIR
The hydraulic unit is filled with oil at CARVER, INC. and should not require additional oil. In the event there is some
oil loss, lower the platen, remove the sintered breather plug, and fill with oil up to the level of the filler hole on 12 & 25
(107 & 223 Kn) ton models. Fill 30 ton (267 Kn) pump up to within 2" (50mm) of top of reservoir. Only special
CARVER # 2170 Hydraulic Fluid, or a brand name filtered HYDRAULIC JACK OIL, should be used. Refer to
Section 6 for recommended substitutes.
IMPORTANT: Brake fluid and similar products may damage your unit and will void the warranty.
3.9 GASES OR DUST REMOVAL
If the product you use in the press produces dust or gases that could be harmful to the operator, attach an exhaust system
to the press. This can be done by either attaching the exhaust vent to the top of the guard housing or by cutting a hole in
the back of the guard housing and attaching the exhaust vent over the cutout. The cutout must be completely covered.
Airflow will then be drawn up, around the material, and out through the top of the press.
3.10 CONNECTING UTILITIES
1. Electrical Connection
CARVER presses that have electrical devices are supplied with a disconnect switch or disconnect plug. Connect main
power to the press through the disconnect.
CAUTION: On presses with thermostat control, customer is to provide short-circuit protection based upon the
electrical nameplate current draw.
The voltage, phase and current draw information are listed on the serial number tag. Line voltage must be within ± 10%
of the voltage listed on the serial number tag or damage may occur. Phase imbalance must be within 5%.
Fulfill all national, state, and local safety and electrical code requirements.
The power drop must include a ground wire.
WARNING: CONNECTION SHOULD ONLY BE MADE BY A QUALIFIED ELECTRICIAN.
2. Water and Air Inlet Connections
If your press is equipped with cooling plates, then it will be necessary to connect the supplied Teflon lined stainless steel
hoses to your plant air and water supplies. Each platen comes with an inlet and outlet hose attached. Determine which
side of the platens you will use as the inlet. For this explanation the right side when facing the press will be considered
the inlet side and the left the outlet side. The hoses are Teflon lined stainless steel, with a 3/8 inch NPT female fitting,
on the end.
Each inlet hose will be used to supply water, air and water/air mix to the platen it is connected to. For this reason, the
inlet hoses should be connected to a common manifold with the plant air and water supply connected to the manifold.
