Raypak Y-200 manual Mechanical Installation, Electrical Installation, Check Your Power Source

INSTALLATION

If the controller was not mounted on the boiler by the factory, care should be taken to select a suitable mounting location. The controller should be mounted on a solid and permanent base. The unit should be readily accessible for maintenance and installation purposes, and should be mounted so that the display is at a height and location convenient for viewing.

Mechanical Installation

Install the controller within 30 feet of the boiler(s). It must be mounted vertically with the conduit holes fac- ing downward. The condui t holes are sized to accommodate standard 1/2" conduit fittings. If addi- tional or larger conduit fittings are required, locate the conduit connections on the bottom of the module.

Slave units, if present, should be installed adjacent to the master unit. (Y-304 slave cable is approximately five feet long.)

Mount the controller using the mounting bracket and appropriate hardware in four (4) places.

A minimum of eighteen (18) inches clearance from the front, and six (6) inches clearance on all other sides is required for service access. The hinged right side of the box should be installed with sufficient clearance (minimum 3” from bolt hole on the right side) to open the cover.

An electrical distribution sub-panel containing appro- priate disconnect switches and surge suppressors is required at or near the equipment location(s).

Electrical Installation

Requires: 120 VAC, Draws 0.5 amp; 60 Hz.

120 VAC Feeder Circuits: Install a surge protection device sized appropriately for your installation at each module.

Install a separate disconnect means for each load. Use appropriately sized wire for equipment as defined by NEC and/or local code. All primary wiring should be no less than 125% of minimum rating.

It is strongly recommended that the controller and the boiler(s) be supplied from the same power source. Install conduit as appropriate.

NOTE: Shielded 18 (AWG) gauge stranded wire must be used to connect the sensors to the controller. The shielded cable should be protected by conduit whenever possible.

NOTE: Minimum 18 AWG, 105°C, stranded wire must be used for all low voltage (less than 30 volts) external connections to the unit. Solid conductors should not be used because they can cause excessive tension on contact points. Install conduit as appropriate. All high voltage wires must be the same size (105°C, stranded wire) as the ones on the unit or larger.

Check Your Power Source

Using a Volt-ohm meter, check the following voltages at the terminal block inside the unit:
